If your goal is becoming a better driver, a Radical with datalogging and a coach makes more sense than a heavy and expensive supercar.
If your goal is more pussy..heavy and expensive every time 😂
@@mbal4052 Funny how the most expensive cars seem to attract the cheapest minge
@@mbal4052 dosent take all that just to get women
I know there's a part 2 coming but would love to see more experience videos like this! Maybe do a offroading trail or rallycross for the first time? Really like this concept :)
I would also like to see a rally edition SR1! 😅
I love that what is basically a go kart can completely demolish way more expensive cars.
Once you do a couple trackdays in a regular road car you go "...I want a race car". Road cars are so compromised for track use (but track cars are expensive :P ) Thanks Drew for taking us along for the experience, you're especially good at this sort of "everyman having an experience" video. Look forward to part 2!
Fantastic description on just how this "baby" track car is to drive and what it feels like. They are brutally quick, and will lay shame to most road going cars on track, even cars 2 or 3 times their price. When you move from a standard road going car to something like this, you really do have to recalibrate your sense of speed. First time I drove one, I come blasting into a corner, only to look down and realize I'm going 10 mph slower than I would in my street car. It took some time to adjust to the engine noise, wind, and vibration to help gauge speed. But good lord they are fun and addictive!!!
For price, in the US they are in the 80k - 100k range new. But you can pick up used ones quite inexpensive ($30 - 50k). The "cost" of operating isn't the capital cost, but running costs. Engine rebuild every 40 hours, gearbox is every 80 hours or so, $1k for tires. As others have noted, they do take considerably more maintenance than a normal road car and are not well designed for repair and parts replacement when something goes wrong. Body panels are EXPENSIVE, so you constantly see them repairing (and strengthening) them as needed. The Revolution One is far far better designed in that aspect, but runs about $200k - $225k new in the USA.
For a much cheaper price (in the USA), you have the Rush Autoworks RAW SR for $30k - $40k. It is about the size of the SR-1, but as a single seater. The SR-1 really is VERY small, and is super cramped for 2 people. The RAW SR is very much like the SR-1 with a motorcycle engine, chain drive, pneumatic sequential gearbox, and has the same easy to drive at 9/10ths. I was so happy after a test drive that I put my $ down on one a month ago....
Why do you have to rebuild the engine every 40 hours? Isn't this a standard Hayabusa engine? I know the V8 based on the Hayabusa is a fragile engine but didn't expect this one to be so.
@@tomwagemans1872 - These engine live in the 7k to 10.5k RPM band on track, and you are at full throttle typically around 50% of the time around a lap. My understanding is that the 1340cc engine is a touch more tolerant of rebuilds vs the 1500cc they use in the SR3. However, I'm just going by what the SR-1 Manual states... 40 hours for Engine Rebuild. I don't personally own one, so I don't have direct experience on how long you could go. I think engine rebuild costs are in the $3500 USD range (no including removal, installation, shipping, etc)
@@DrPyro2k I also wonder if it really requires rebuilds that often.
Motorcycles used for track days live at the top of the tach all day long, too, and they don't need rebuilds with anything like that sort of frequency.
How is that Rush SR1 compared to a Radical SR1 or SR3? I don't like that it's single seat, and I don't like the looks of it as much, but the price is right and I love that you can replace just one small body panel if you damage it. How is the performance and quality compared to the Radical SR1/3, though? (a used one would be in the same price range as the Rush.)
People never realize how much better a dedicated racing car is. Spectators go crazy when they start to see road vehicles that are one offs and supposably track focus. However, those vehicles are street purpose. So they’ll be compromised when you get them on the track. Put a race car with downforce and you’ll see how much faster you truly are. About the only thing on the track that could match it a little would be the bac mono. Even then, it’s a little compromised, which is why you were able to lap it so easily. 👏🏻. Also, a radical isn’t all that expensive for a truly track focused machine. Sure, you’ll have to purchase a truck and a trailer if you can’t store it locally at the track. But I think it’s still cheaper than getting a limited edition street vehicle that pretends to be track focused. 😉👍🏻
Can’t wait for part 2! 👏🏻
I had a road legal one exactly the same plus light handbrake and horn. So much fun.
Another excellent video from Carfection - I want more!
I've done a fun 3 laps at Castle Coombe in an Ariel Atom 3, that was an absolute beast (nowhere near the limits apart from rear wheels spinning up on straight) - it had a similar power-to-weight ratio, but the downforce on this Radical would put it in a different league, I reckon :)
They are! The cornering forces are v v high and I found them a lot more neutral than the Atoms I’ve driven (which have understeered)
Can't wait for part 2
How was that!! Just watched the replay of todays first racing action in Australia in over 3 months. Our local Radical series was first up!!!! ..and straight after I see this youtube video posted from Carfection!!!!
Radicals are awesome in person especially when its just radicals racing. epic racing there are also radicals with 2.7L v8 engine, thats 2 HAYABUSA heads mated to an in house block (Unique Radical designed and engineered RPE 2.7L V8, 10,500 rpm) but you must first learn from the begining
I was invited to try the SR1 and SR3 and managed a few passenger laps in the RXC at Silverstone.
They are brilliant cars and the sense of occasion is very high from driving them.
I’ve lots of motorbike track days and it took me a while to get used to the braking and cornering loads these things can generate.
I’d love one!
370Hp per sounds good!
Also how much it cost 50-60K?
2:53 That look tells 1000 words:)
Very calm and detailed review. Nicee. Highly recommend to try - REVOLUTION RACE CAR next time! No problem ;)
I have never been on a track and never unintentionally spun a car. but honestly, finding that limit on a track will make you a better driver. I guess I need to go to a track now. bye!
Cool
That's a Hayabusa engine
Drew, you are a lucky two watched bastard! 😅👍
so its a hayabusa engine, i see great potential ;)
anda busa gearbox.
So time for a turbo or a compressor.
LIke how it was being trolled by the BAC Mono in the last shot.
That shit was fast man
how do these compare to the Ariel ATOMs
whilst my race kart breaks ribs cornering 🤭
This car is so Radical!
Gotta go fast, faster than ever
Is the engine based on the Hayabusa engine?
Busapower!!!
Wait until you add slicks, a rear diffuser and bigger throttle bodies to take it up to 225bhp. Thats when it gets fun :)
If only they had a car like that….
overtook a BAC mono, that incredible
You do know that he broke the track day rules doing that? The mono (and I know the owner) was on a warm up lap and waiting for the next straight to overtake the Porsche in front safely … as he should. The track day rules for that operator are overtake on the left on the straight and with permission … total fail for Drew
@@jasgts the only thing I know is that BAC mono is a rocket ship vehicle. 😀
@@julieli6313 you are completely correct, it is … I love mine
All that data on screen with the video also needs a course on how to interpret and use it to your advantage
Cars like this not for some countries that have potholes everywhere on the road.
Someone got a prism 😉
Is the SR1 as quick as an SR3?
how much?
So it’s a Hayabusa engine then?
sooo how much's the thing
Im confused as to how this is quicker than a BAC Mono, especially on a straight?
Driver...?
It isn’t. Could be the mono on a warm up or cool down lap. Drew also broke all the track day rules by overtaking in a bend - very poor example to be setting on a video
@@jasgts advanced run groups allow passing in corners at practically every track day I've ever been to.
@@joshduke134 I’d assume that’s not in the uk or is for bikes? It’s never been allowed at any track day I’ve done in the uk
@@jasgts Correct; I'm in the colonies.
That steering wheel is positioned so low that it must be odd steering from the elbows more than the wrists
Pretty sure he’s moving his wrists a lot there
I'll stick to indoor rpm racing
Great fun from Drew much better than his attempts to convince us that Kia's made out of jelly are anything other than a white good.

I always liked Radical, that was until I looked over the newly unveiled version at Goodwood 2019. I was massively shocked at the quality of the fit and finish, nothing lined up and the fiberglass/carbon was so wavy it looked like I did it. Didn't give me much confidence in the quality of the overall package.
I then checked out the bac mono, and yes it was 4x the cost but it looked like a peice of jewelry, but I don't get the single seater thing.
Fit and finish have zero relevance for a track car.
@@engineer1692might be true if you're building it in your garage, but when you're buying it should be right up there.
@@engineer1692 absolutely correct
This felt like a comercial...
