I would speak about some technical aspect of PRV V6. 1. It has 90° between the cylinders because it born as modular engine, it is not true that it born as V8 that became V6 but it was designed from the beginning in way to be a modular engine, V8 and V6. After, during '70 , Peugeot, Renault and Volvo decided to don't make V8 version due to austererithy. 2. V6 at 90° instead of 60° doesn't give big problems, in fact I found a report of Peugeot (that designed it) where the engineers explain that vibrations are little bit higher than V6 60° and much lower to 4 cylinders at all rpm, btw it is not the first engine odd fire in the history, and it is not the first V6 90° also (see Maserati-Citroen SM and Biturbo). 3. PRV is entire aluminium alloy engine, with chains for camshafts on heads instead of sinchronous belt (that some manufacturer already started to use) and emipheric combustion chambers; no bad for beginning of '70. 4. About low power: please remenber that in 1975 (just an example) the 2.7l of Porsche 911 (standard no S version) had 150hp, exactly the same of Alpine A310 with PRV 2.7l; famous Alfa Busso V6 2.5l in 1982 had 150hp. Please remember me how many (normal) cars (no supercars) in 1986 had 200HP? Renault 25 Turbo and Renault Alpine GTA Turbo had this power (just some examples: I remember Lancia Thema 8.32, the monstre, had 215HP; Ford Sierra Cosworth also 200HP, no more...). 4. At the end please remember me all the fanstastic and reliable engines was better than PRV: V8 Rover, V8 Triumph, 6 cylinders Austin...
gotta remember the venturi atlantique with the prv with 600 horsepower
Jeez you’re just a bunch of no-knowing googlers chatting away aren’t you
Agreed.
My PRV may not be fast but it has been reliable in my DeLorean.
Mine too! Spec-1 exhaust system and a cold air set up and throttle body spacer and still run the reliable K-Jet! Car runs and pulls like a champ!
The PRV was a strong engine. Not as reliable as the V6 that replaced him later in the 406 pininfarina that was clearly underused ( N/A with a little preparation it could spit out 300bhp with its only 3L) . The PRV could withstand a tremendous amount of boost, and I've seen 500BHP PRV that lived to tell the tale.
600hp in the Venturi LM600 racecars.
I like the PRV to but the problem was at the beginning, it was meant to be a V8 but they never finish him, this is what explains this lack of a lot of things in the PRV
@@benjamincharlin6770 but it was never meant to be a V8, they made a V6 and wanted to make a V8 out of it later, but that was shut down.
@@benjamincharlin6770 no, a V8 PRV AND a V6 PRV was planed but because the petrol crisis in 1974-75 was the V8 abandoned. A V6 with 90° angle is the most common configuration (to reduce the engine height and simplify the intake) , but need a special krankshaft to run soft...ideal angle for a V6 is 120° (only use in F1 engines), not 60°!
hello 406 is PR24 ENGINE la française des mécaniques prv12 is cool engine
I personaly think that you miss the point with this engine, it originally made for the Peugeot 604 which was a luxury car so of course speed wasn't the top priority for this engine and the other problem is you only speak about bad or ugly cars ( except for the DeLorean of couse ) because some beautiful and good cars were made with this engine. I think you should also speak about that and not only 4-5 bad cars.
corentin troadec couldn't agree more! They forgot to mention that the Safrane Biturbo was available as a Baccara Squadra version, which has 4wd and a 268 hp prv engine tuned by Hartge. And what about Venturi with all their prv cars?
you're absolutly right, i mean Venturi with the PRV V6 could beat Porsche back in the days
Yep, performance was never really the goal, the PRV was a very popular, all-alloy engine, almost 1 million were made, went in a lot of cars and produced from 130-200hp as an N/A setup and up to 910hp with forced induction in the P88. And the whole chopped V6 story is rubbish, they planned to build a V6 first and later a V8 version but the oil crisis caused the V8 version which was to follow to be abandoned. The engines were a 90 degree config for two reasons, to fit into the engine bay of the ever more popular cheese-wedge design cars which were becoming popular at the time and to simplify production, both the V6 and the V8 could be made in the same factory with the same tooling, you cannot design a V8 and "chop two cylinders off", that's not how it works.
It was originally a v8 too.. Because of the fuel crisis it became a v6 instead, and thats a shame, because a around 250 hp v8 would be a lot better fit for those old heavy volvos. And french luxury cars would have been more awesome too with that extra power. The delorean would be.. Well still not a supercar by far, but a whole lot less slow.
Yes, by modern standards its slow, but american v8s of that era were often even slower, it runs circles around american v6s of that era. So all in all id say its pretty decent for a 70s v6 engine.
So the corvette made 200 hp with 5.7 liter in 1982. Prv made 130 hp with 2.8 liter. But it's only the prv that is garbage...
Yeah.. That PRV must really be a piece of garbage... Considering that a Ford 302 of that vintage came with only 129 horsepower. The PRV was a good engine. I liked the Eagle Premier and Dodge Monaco. I thought the engine was smooth, had a nice growl, and had plenty of power.
Guys what are you talking about !? Top speed record at Le Mans is 405 km/h, and it was set on Mulsanne Straight in 1988, by the prototype WM-P88 with Peugeot’s 2.8 PRV V6 Turbo engine, driven by Roger Dorchy.
Please just check it out ok ! :)
Ok so... Where's the argument?
Doesn't the PRV still hold the record for clocking the highest top speed on the Le Mans straight? That sounds like a great engine to me. The PRV in an Alpine is really a great fit. The car does move... Yes.. the Delorean could have benefited from a more powerful unit, even a V8; however, I feel that if it was given the twin-turbo setup that DMC has now, it would have been great. If was emissions laws and ridiculous ride-height laws that gave the Delorean bad press when it was launched. European version were a joy to drive in contrast.
As far as I'm concerned.. the engine isn't given the good press it actually deserves. It's not the best, nor it is the best sounding, but it is a good one.. IMO.
The commenters know more about the topic than the hosts.
The inaccuracies here are so extensive it's almost funny. Friends, the Hollers, have nearly 900,000 miles on theirs. I have over 125,000 miles on mine, without issue. Unreliable? Lol. Keep perpetuating the myths fellas. Appreciate the commenters pointing out the faults and subjective arguments.
Have owned couple of Volvo PRV last 35 years . First Volvo PRV back in 1985 a 1976 264GL B27E ( 489km sold in 2002) Anniversary model, then a 1982 760GLE ( B28E) in 1990 ( 385KM sold in 2004) and now another 1977 264GL B27E 233KM ( bought Oct 2017) . It was in storage for 17 years , got it running in three weeks and in process of recommissioning back on road. Also PRV here in NZ are HIGH compression version and not the LOW compression that US/JAPAN market received. A PRV with M51 gear box is a great combination . Even Alfa Romeo 155 TI was using PRV to win the DTM back in 1996/1997 season, 490HP N/A with Lancia-Thema PRV V6. . PRV is a very strong engine with fully skirted cross bolted cap It was the bases for F1.5 liter Renault-Gordini V6 turbo Formula 1 back in 1977 that produced 1200HP. @12kRPM . The PRV just keep on going if you look after it IMO like any other combustion engine.. oil change every 5K is a must.
The difference between a "GOOD" and a "BAD" engine is reliability and durability; not power output.
I hear engines are designed and used to make power.
Failiures in the cheap heath-robinson cooling system on my delorean have overheated the engine a dozen times, and it hasn't caused any permanent damage. The engine is very resilient.
The Safrane Biturbo was All wheel drive... The german company Irmscher did the body work, and Hartage developped the engine. The car was ok, except his gearbox which was to fragil, and the price was a little to expensive, when you take in consideration on that It was a Renault...
I was going to say the same thing about the Safrane Biturbo. IIRC it was only available with a manual gearbox because Renault didn't have an automatic transmission that could handle the power and torque.
Don’t blame the engine. In fuel-injected form, my ex-DeLorean development Alpine A310 develops just over 200hp; after USA emissions it was choked to 130hp. Don’t blame the engine. Friends of mine very successfully race Alpine A310’s and average reliable 285hp. Don’t blame the engine. John Lane in the USA gets over 500hp from his rally engines and is hugely successful. Don’t blame the engine. And don’t criticise what you have no knowledge about!
These guys probably don't even change their own oil. I agree with you though, the prv engine was extremely versatile and relatively tough for the era that it came from. These are good Motors and they are capable of making tremendous power
The Safran Biturbo actually had 4WD, it wasn't a success though
I had two Peugeots with this engine. Reliable, long lived, low stressed. It also had a lovely sound especially in the original oddfire configuration. . It was relatively light as it was all alloy.
the only thing in this video that is hilarious is the faces and haircuts of two guys thinking to be funny
If it's so bad, then tell me why 3 types of Alpine use it and even more Venturi ?
sunk costs and availability. Douvrin cranked out close to a million of these mills.
@@juankenon And yet, Alpine and Venturi are praised again and again
@@me67galaxylife Those aren't mutually exclusive, they were working with what was readily available to them at a reasonable price. By the time the venturi rolled around the prv had been refined from its original iterations and they then pushed its performance envelop further. My only personal experience with it was in an 82 Peugeot 604. I wouldn't call it a terrible engine, it was competent for the era, if a tad thirsty.
F1 engines night now are essentially early prv v6 engines. Single pin crank odd fire right angle v6. I want one!
Renault Safrane was a pretty cool car. I don't know what the hell you guys are smoking. Way cooler than anything American or Japanese in the segment from the period that's for sure.
Was hoping for some discussion over the technical aspects of the engine.
The initial engine for the dmc 12 concepts was supposed to be a rotary engine.
glad it didnt come.
I never understood why John Delorean didn't license out an engine from GM with all the connections he had. Just take the Buick V6 and slap fuel injection on it.
Better to use the Chev small-block V8!
after how he quit I doubt they wanted to supply him with anything plus he's the competition why would they want to help a direct competitor.
At the first time DeLorean wanted to use a motor from the future he wanted use a wankel motor from citroen but couldn't, so use this other choice, the second most futuristic motor at the time
The factory was in, I think Ireland. Probably was way easier to get a domestic engine then have an American engine imported.
So what exactly is bad about that engine?
Alexander Siebert they’re slow and unreliable
@@NiksGMD no, those people don't know what they are talking about
Benjamin CHARLIN
I actually had one and something was breaking in it every 2 weeks
@@NiksGMD the latest version was a bit unreliable and always had a lubrification problems, like most 60's V6, it don't like being neglected. But overall it is quite a good engine, prove itself in rallye raid and in some race.
ferkemall yes, i had a Citroën XM and i was on the side of the road everytime with it
is this not the same engine which came stock in the DeLorean?
Wasn't the twin turbo Renault thing 4wd?
I remember being in my dad's 264 Volvo and suddenly oil and water started spraying everywhere!
NO THAT SAFRANE IS BOTH EXCELLENT AND VERY GOOD
The power it makes is perfectly adequate for a 2.8l v6 from that era
I've seen a DMC with a turbo Buick 3.8L in it, it's fast as hell buddy runs it at Cayuga speedway.
This discussion is way more entertaining than goofy contrived "arguments".
We had a 1982 Volvo 264 with this motor and got 285,000 out of it before it blew. So it did last. Horrible gas milage though
Us Volvo enthusiasts prefer to forget the PRV's existence. In Volvo land you could find it in the 260, 760 GLE and even the early 780 Bertone coupes. I guess in the 70s when a 240 made under 100hp the PRV powered 260 was probably an upgrade, but when the 700 series came out Volvo's own redblock turbo engine easily outgunned the PRV and was considerably more reliable.
We NZ Volvo enthusiasts love the High compression PRV. Dont think USA/Japan ever received any high compression PRV B27/28/280E engines ? on Volvo 264/265/262c/760/780/960/?. Stock B27E produces Gen1 104Kw then Gen2 109KW and B28E 115KW . Not bad for an 1968 designed engine..
DMC Houston has a PRV V6 that has more horse power now with all things updated
My DMC can breath with long tube header and two three barrel Webber’s even with out a hot cam to come. Remember this was jimmy carter times of choking smog controls and detuned engines
I had this engine in a Volvo 265. It was junk. It would stutter and stall, quit if you made a turn, was gutless. After I traded it I saw that exact car parked on the street and the new owner was getting into it. I said to him “Hey, I used to own that car.” He gave me a dirty look and said “Do you want it back?”
Talking about something they don't know and that is french: of course they are going to talk crap about it.
Well I already had very low esteem of Jalopnik, but this is really hitting a all time low. I fell like thoses guy just looked at the wikipedia page and went on with it, it is just appaling to see their lack of culture and how superficial their analysis is.
You could have made a interesting point about that engine that was sometime misused but... no.
Some of the fact you quote are just plain wrong... the Safrane Biturbo isn't front wheel drive for example (and I don't think it is a bad car). Other mistake the PRV V6 isn't unreliable, just think for a minute: if it was it wouldn't have been used for so long and by many people if it was.
Yep. Safrane bi-turbo was all whell drive.
French cars are terrible! I know, I've worked on them 😡😡😡
Benspeed's Channel they are only shit if you don't know how to maintain them :D
Dom's Garage I know how to maintain them, they are still shit
Really? what car for example?
For the time is was acceptable. For example, had Honda supplied the engine it would have been the 1.8 Ek motor with 96 horsepower. The Toyota inline 6 from the mark ll Supra would not fit. Didn't make more power than the PRV. GM 2.8 was 120hp. At the time, for what was available, it wasn't a horrible choice. But how can I explain this to two chatterbox that I've owned cars longer than you two been alive. PRV is not perfect, but and smalll power plants of the time, it's ok. You need to put into context. They're still rebuilding them to this day in numbers for restored Deloreans. Name one 1981 Honda Engine from 1981 worth rebuilding for any iconic car?
That's the thing, what post OPEC malaise era engine is really all that inspiring?
The human gibbon Raphael is wrong, discount Doug Demuro's delightful Delorean demonization is dead accurate.
Oremud Goud was separated from his twin at birth. He cares neither for quirks nor features.
Funniest comment I’ve read in a long time
"Discount Doug DeMuro" hahaha
The PRV6 was not the best choice for the Delorean. Originally the Rotary engine that was used in the Mazda RX7 was supposed to power that car.
But now, the Delorean is the property of the community who loves the styling and look. There are many LS swapped Delorean’s which really fly down the road. There’s also Stage 2 Delorean’s which you can get from DMC Texas. It’s truly remarkable what’s happened with the Delorean.
Many years ago, I had a 1979 Volvo 265 Wagon. I thought it would be a good car, since it had an Aluminum V6 vs the 2.1L Red Block Volvo 4. Well, the PRV motor wasn't very good. It didn't idle well, was pretty gutless and it had to be tweaked to pass emissions. The 2.1L on the other hand could be abused (late on an oil change ... no worries), driven 100 mph all day long without overheating, would last over 340K miles - my 1978 had 340K (my guess, because the odometer broke twice). Bulletproof as you can get.
The 2.7L PRV did not work for me. Every Volvo I've owned has been a good or excellent car, except for one, the 1979 265 Wagon with the V6 2.7L PRV motor.
Need one for testing Purposes this TwinTurbo thing sounds like you could turn it up with new technology
I always thought the Volvo redblock would of been good in the Delorean, with a turbo. Would of suited the 80s furitistic vibe as turbocharger on production cars were uncommon and they could of put a cool turbo badge on it.
This, and, if the DMC 12 lasted long enough they could have put in the 1984 only B23FT from the 700 turbo series with an intercooler. It would've been an absolute rocket for such a small engine.
Guys, I like your article about the Avantime but what the heck are you talking about the Safrane? It was a competitor to the E-Class, BMW 5 Series and Audi 100/A6. But in my oppinnion it was (in the "Baccara" Trim) above them. Electronic controlled Dampers in combination with Air Suspension, Ergomatic Seats (air cushions in the seat for more comfort), talking controll system, dual zone climate control, electric adjustable seats (including the rear seats!) and so on.... The Safrane Biturbo was ALWAYS AWD. Not FWD! And with those 2 Turbos the PRV Engine is a beast. They run 260 km/h. Without the turbos and with only 12 Valves the engine is indeed a bit "tired". PSA did a 24V Version (without Turbos) that runs pretty quick.
Take a look: ua-cam.com/video/UyHft8bMnXM/v-deo.html
It is so bad that Venturi (French sport car manufacturer) used it in their cars. Alfa Romeo used as a base for their DTM beast (155 Ti) and it was also the base for the Lemans Mulsanne straight record holder the WM P88 topping at more than 400 kn/h.
I have a Volvo 265 GL 1978 with a PRV B27F, I haven't daily driven it daily.... yet. but it has 105k on it, seems to be well maintained. like proper weight oil and oil change frequency. I like them. I also love the D24/D24T from VW. and the Volvo B21/B23/B230F / FT engines. I have a Great love for them. however, If you don't treat them properly then you are going to have a bad time. I feel that it is important to know what grains to feed it for maximum enjoyment.
This is the best one...
It has just the sort of irrelevant-to-daily-life fun facts I love
Calling this engine a "boat anchor" is a complete and total misnomer. This engine was (and still is) a lightweight design, weighing far less than most competitors of the day at the 2.5-3.0 liter displacement target. It did have it's flaws to be sure. For a engine weighing around 345 lbs in the 80's, 200hp was an excellent output. This was the original design target, various emissions and tuning standards brought it down to around 150hp, which is still quite good for 345lbs of fairly low center-of-gravity weight. By comparison, a BMW M20 was 400lbs and that topped out at 2.7 liters, it was also a lot taller in terms of center of gravity. The M30 was another 60-80lbs heavier still. If the PRV was a boat anchor then BMW's sixes were even more cumbersome (which honestly, none of these engines, PRV or BMW, are what you'd call heavy or an "anchor") Both of those BMW engines had similar power output to the PRV in the late 70s and early 80's. When it comes to engine smoothness, people pay too much attention BY FAR to this notion of "inherent balance." Every adolescent gearhead knows that I6's are balanced, as are cross-plane V8's, and that 60 degrees is the only proper way to make a real V6 right? Horizontally opposed engines are naturally balanced right? Or are they...? News flash, in the real world there ARE imbalances even in all these so-called perfectly balanced designs. That is where NVH comes from, *every* engine on the planet has it regardless of cylinder layout. Engineers, when designing a powerplant, take in a wide variety of competing design requirements from an NVH/vibration perspective. These PRV 90-degree V6's aren't any more or less smooth than any other V6 within their design parameters. At the speeds 70's and 80's cars revved to, which is when this was designed, there is absolutely zero difference. Ferrari makes a V8 with a flat plane crank, the balance on that is absolutely atrocious. Think two I4's competing with each other for a contest of who can be the noisiest/shakiest, yet nobody is complaining about a Ferrari V8.
I used to own a Volvo 264 (In Australia). It had the PRV V6 in it. The thing I found amazing about it was that in city driving I would get about 250kms to the tank of petrol... which is SHOCKING!.. BUT on the open road I could get 640kms to a tank.
LOL I had the Peugeot 604 with carbies agreed the fuel economy was horrendous but much better cruising my 750iLbimmer 5.0 v12 had better fuel economy.
I want remember to everyone that the famous V6 TI in the incredibile alfa 155 DTM was an evolution of the PRV V6 mounted on the lancia thema
Search for Alfa Romeo 155 2.5 V6 Ti Touring car. This car used the PRV engine block with Alfa Romeo designed heads and periferals. This car won many TCC races and Championships. Ir even won the DTM leaving behind Mercedes Benz.
I think all the love for the PRV's "fantastic well-built reliability" in this comments section comes from people who don't know what 'realiable', 'fantastic', or 'well-built' actually mean
Bad language for this engine.if you read and search the v6 prv engine was the base of 1996 alfa romeo 155 dtm .so an engine near 500hp n/a with over 11.800 rpm os not a garbage
These guys couldn't close an umbrella.
Raphael, great name , great hair. Approval from the South Coast.
Very amusing.
cool
Currently having a debate with a guy who says the PRV was a great engine because of the numbers made...I think he's missing the point
🤔🤔 wasnt this engine in the racing Alfa Romeo 155 v6? Not the busso engine, Im talking about the race car.
So I guess it's not bad at all...
Not a garbage, remember the Alfa 155 v6 ti? well , in terms of homologation for DTM, they had to use it, because Alfa Romeo couldn't use his engine, and couldn't use one out of production, like the Montreal one. Alfa 155 was one of the most iconic car in racing history, and had this engine, obviously over-tuned by nice crazy italians lol.
Oh yeah! what a car Just watched Davide Cironi's Drive Experience ua-cam.com/video/BMAPcaC4Yx8/v-deo.html .
Finally something truly informative and interesting in carguments. Thank you.
Safrane es malo según ellos?, me parece mas atractivo que vehículos de EEUU de esos años
The PRV V6 in its 12 valve form was very reliable, even if a bit underpowered. The 24 valve 3.0L version as used in the Citroen XM and Peugeot 605 was more powerful but highly unreliable in the long run due to lubrication issues.
the 3l 24v is only PR ,build on ,la française des mécaniques (ont Volvo) an prv its the same
I add that probably PRV with very low power (130HP) was the wrong choose for a DeLorean but it is not due to the fact that is PRV but beacuse it had too many few HP. If DeLorean used the same engine in Alpine version (that had 193HP) the story was different, maybe.
The PRV use by Alpine Renault on the A310 was the 2664cc with 150HP never the 2.8L...And the later A610 use a turbo PRV
@@leneanderthalien Not completely exact: the Boulogne version was 2850cc with 2 carbs triple barrels, new cams and so on, declared 193Cv, 0-100km/h close to 6s. Few cars manufactured, maybe 34 pieces. That was an evolution of a Talbot Tagora engine that had 185Cv. It sounds like good music
According to Wikipedia, the Safrane never eeked out more than 165 hp from it's PRV. en.wikipedia.org/wiki/Renault_Safrane
Huh, really interesting. As someone in Europe, the big French cars always used this engine for decades, now I know more about it. Cheers.
The dude in the white shirt is Doug demuro wearing a slight disguise
If you cut off part of Doug demuro, another one grows from the severed piece of Flesh
What's sad is that this engine started as V8 but they axed two cylinders because of the oil crisis.
@4:48 : The SAFRANE was not imported in USA only because RENAULT had left the US market by then !
The safrane biturbo is all well drive and developing 264 bhp it was prepared by hartgue but his gear box was so dumb that the horse power was limited otherwise the gear box break every 40000 kilomèters
Where I can see that info about 40000 km?
bore size 93mm ain't shit, GTR only used 88mm, PVR just need a right gear transmission, and new buttom stock
The federalised US spec had 130bhp the European spec had 170bhp and had a lower suspension set up because of US crash regulations. That not to say it wasn’t bad car it was compromised and flawed but I’d have one purely because of back to the future if I ever had enough money
Great episode
The power was right on point for the era. There were v8's twice its size making less power at that time. These guys have no clue what they are talking about.
I want to SHO swap a DeLorean.
UUMH ALFA V6 DTM __2.5 PRV ENGINE NEARLY 550 HP n/a
I was hoping they actually did some research for commenting on cars they never drove, saying a Safrane was a bad car for instance, like the world needed more opinionated Americans already. Bae, back to regular car reviews or something...
Probably the best comment here. I could tell that this is just their opinion about something they have no experience with. Jalopnik, for idiots by idiots
Late to this video. But i have to disagree on some points. firstly, the prv was never a v8 with 2 chopped of cylinders, the v8 and v6 was designed at the same time and like mercedes's m112 / m113 v6 / v8's was designed so that they shared as much tooling and parts as possible. Secondly it should be noted that there are really 2 generations of prv's gen 1 from 1974-1985 ish these are the ones that earned the engine it's bad reputation. the second gen motors which came 85-86 ish although similar looking had so many changes it's debatable if it's even the same engine. different crankshaft, heads, block, pistons etc. the 2nd gen motor has an even firing order unlike the earlier oddfire engines. they have oil cooled pistons and forged crankshafts that are very strong, the 2nd gen motors also have cross bolted main bearings.
The prv is also quite light for it's time at 150 ish kgs / 331 lb which was lighter than volvos then new 2.1L 4cyl redblock engine. the gen2 engines have 80% of it's max torque available from idle and up and never dips below 80%
The renault safrane you mentioned is in fact awd and worth mentioning ran only 8psi/ 0.55 bar max boost and a ridiculously low compression ratio of 7.6:1 to make it's 258hp and 263lb-ft / 363Nm max torque. The engine was capable of more, but renault were worried the gearboxes couldn't take the power.
Is the prv the best engine in the world? no definitely not. Is it the worst engine ever made? also no, i think the earlier engine definitely deserved it's bad reputation, The later engines do not. although requires more frequent maintenance. and is plagued by not sophisticated enough fuel injection systems.
Certainly the early V6 suffered from cam wear on startup, but later ones had an oil bath cam, and the one in my 1990 760 has done nearly 200,000 without major problems. It is certainly smoother than any of the 4 cylinder Volvos, and being late non-cat spec seems fast enough. The only thing I don't like is that the FI system doesn't have many options for fiddling with it.
My Volvo 780 has 200k miles on it's PRV and it's the wiring that's shit not the engine.
alfa romeo win the dtm championship with the PRV!
The Alpine A610 was way cooler than the De Snorian..
The PRV is a total piece of shit, but it's actually one of the better things about the fucking awful DeLorean. There's a reason why both Peugeot and Volvo replaced it as soon as they could, Peugeot with the excellent ES 24-valve V6 and Volvo the short-block straight-six. The Safrane Turbo was a great car though! Very technically sophisticated and a lot more reliable than you'd think, as the engine was completely redesigned and rebuilt by Hartge and Irmscher... and it was 4WD, so you guys are plain fucking wrong about that! Some later Safranes got the ES-series V6 too, and that was a GREAT engine. They also used the Volvo inline five on some lower models... lovely engines but (ironically, as they were 100% Volvo) rather fragile compared to the robust French V6.
prv great v6 engine
the worst car besides the Delorean to have the PRV has got to be the Alpine GTA & 610. When they updated that car, they just reused the old 310's engine :( Its still a really cool car but it could have been so much cooler if they licensed another engine like the Alfa v6
Russell Robinson Except that Alpine was to Renault kind of what Abarth is for Fiat.
The A310 V6 was a 2664cc with 150HP, and the A610 V6 was the new version from the PRV with special crankshaft for smoot running, with 2975cc and 250hp (later had 280HP)
@@leneanderthalien Oh I did not realize the 610 had such a substancial bump from the GTA
II have owned several cars with the PRV V6. One I still have which is an Alpine GTA with the naturally aspirated 2.849l V6. It was strange in that it had the very odd Single choke solex and a twin choke solex. The car was very easy to drive but took a bit to get in stride, had a strong midrange but ran out of puff around 5,500 rpm. Even so the aerodynamics were so good it could still nudge 150mph on a long straight. I had the carburetor changed for a twin choke webber (off a south African 3.0l ford) which dramatically improved the off idle acceleration. A couple of years later when the muffler developed a hole I had a custome made stainless steel free-flow exhaust made. OMG the car would rev instantly and easily to 7000 rpm. This transformed the driving experience from very good (the car corners exceptionally well) to utterly fantastic. 6500 rpm was the new sweet spot for changing gears and driving it is like ballet as you obliterate the corners with total confidence and just flow down the road. The engine is totally reliable and will respond to tuning. Porsche did the tuning on the Clio V6 upping power to 255bhp, and I know people who are getting 300 hp from there PRV V6 engines without forced induction. The car now can confortably top 150mph, however, its the combination of the new found throttle response and very high grip levels that make this car such an incredibly fun car to drive ( the Hallmark of all Alpines) The PRV V6 "honi soit que mal y pense!"
It not like your american V8's were that great either after the oilcrisis of the 70's
The V6 PRV an "unreliable engine". You obviously don't have a clue ! There are still old running cars with that V6 PRV today ... not bad for a "rubbish engine" ...
1% of the PRV's still run, they are total unreliable crap...
You can say that for fucking anything, if something is well maintained it will usually last a while. But if the engine is treated like most beater cars they will last not as long.
maybe the old odd-fire engines were unreliable and underpowered but Volvo re-developed the PRV (B280F, 170hp,Volvo 760/780) which was a hell of a lot better then the first PRV in the Peugeot 604 and PRV B27 in the Volvo 264/265/262coupe Bertone
The PRV was a modern aluminium engine which was uncommon back then. The odd fire design caused by the hacking off of 2 cilinders from a V8-design caused it to have a weird crankshaft, distributor cap and odd firing order. On top of that some PRV engines (Alpine A310) got a weird carburetor setup that was not easy to diagnose, setup and tune.
You needed more knowledge then the averidge grease monkey to maintain a PRV engine
the PRV was also used in the Venturi, a beautiful mid engined sportscar from Monaco. This car was turbocharged and the fast versions (LM600) also raced in GT1 in the 24 hrs of LeMans in 1995 .
3 Venturi cars finished this very hard race. Very respectable
Peugeot 605 and Citroen XM had PRV's with 24 valves, these engines were not underpowered at all.
all in all this video is full of fake fact free 'info' and internet lore.
I had a Volvo 760 with one. It is a rubbish engine.
Most of it's "bad reputation" came from the odd firing carburated first gen PRV which idle poorly, had carburettors that were pain in the ass to tune, and on some rear engine cars had issues with the cooling system, but the updated versions with fuel injection were kind of bulletproof with proper maintenance
Sorry but assholes here(!?). What a great sounding engine and Alfa used it as a basis to build their own V6 to beat the Mercedes and Germans in the DTM..
if i can buy a DELOREAN i swap 13B MSP WANKEL ENGİNE :D
hahah yeah these guys talk such shite, remind me how much power American v6's were pumping out around the same time as the PRV's were in general use?
Don't know why I bothered, you quite categorically have no clue do you?
These guys don't know crap.
Renault = Run? No!
renault produces f1 engines
Very ignorant...
Ignorance begats arrogance.
please stop with the "like" "like" "like" millennial diarrhea.
Forget the PRV6, The Infiniti VQ35/VQ37 is old outdated garbage that's STILL being used. And that noise, ugh!
Let's discuss rationally in a calm and collected way.
FedoraMcGentlesir 350z and 370z seem to do just fine with it. I don't shit about engines but I've seen both of those making good power with turbo/twin turbo setups
If you wanna argue that VQ motors in general are bad, thats not true. The VQDE motors are bad because of oil consumption issues & they don’t like making power beyond full bolt ons, but HRs are decent platforms to build on and they’re proven to be reliable until 500hp on stock block.
How are you so confident in being wrong?
ShoryukenDatAzz
If I agreed with you, then we'd both be wrong.
Disagree, vq35hr and vq37vhr are stout motors. Not very efficient but stout powerplants
has anyone here ever worked on a PRV in the DeLorean? - everyone "NO" stop posting please.... this Engine is truly a POS. Need to take the entire Engine apart just to do some fix on the Distributor, etc. Change Cams? Welcome to take the Heads of and everything above. Takes two days and then good luck that it will run. That´s the reason why so many have survived sitting in Barns garages, etc. As they failed no one could really fix them easy and the got stored to "fix one day". NOT because they were so well built. PRV - no thanks !!!
The fuel distributor is on the top of the engine and the spark distributor is immediately beneath it - why do you have to take the whole engine apart to work on them?
