- How did Université Laval win the 2014 Shell Eco-marathon Americas? Attention to detail in all the parts of a vehicle that consume energy. Low rolling resistance, extremely low drag, and a highly efficient engine. Though they had previously hit numbers in the 3,500 mile per gallon range, Université Laval still managed to take home the win this year achieving 2,824 miles per gallon with their eco car.

NEW VIDEO EVERY WEDNESDAY!
For those using the metric system, that's 1200 km per liter or 0,08 liters per 100km,
2:18 I love his expression / reaction when being asked about the mechanical aspects of the vehicle.
Straight from Québec Province, really proud !
good to see you get some proper recognition with your channel. I am so jealous of your job and your wrx sti.
I understand that he was nervous and struggling with his answers since they were trying to solve a problem with the car during the competition and he was not speaking in his native language. To help with the comprehension, you did repeat or rephrase some of his answers and it helped alot and make the video more interesting..
Felicitation les gars!
I wish you had the guy speak in his first language, judging by his accent I would hazard to guess French, then translated it.
Right from my hometown! Way to go guys!
Hey @EngineeringExplauned, I'll run with my team for Shell Eco Marathon Brasil and hopefully win it. If I win, I really would like to meet you in Shell Americas 2020. I'm such a great fan of you and think that your videos are great.
Omg you were 10 miles from my home god i wish i knew you back then
Do they run this uphill sometimes? or are the 6 miles mostly flat? Even if the road is flat it is still amazing!
Pretty flat, yes.
Engineering Explained lol.
at 1:03 you asked abou the size displacement, and he replies 39cc.. think you could make a vid explaining the CC, thats something i've never understood, starting back with Super MarioKart... pls
justedbin CC, cubic centimeters. It's the displacement of the engine (the volume the piston sweeps between its lowest point, and its highest point).
so... the higher the cc the higher the octane?
Nope, the higher the volume of the engine. Octane is something relating to the fuel: Octane Rating - Explained
I think it would be a little more practical if it could go 60 mph+ even if you would have to put like 85cc motor,it would still get at least 200mpg probably
With its 1.9 HP engine this thing probably *could* go 60 mpg if they adjusted the gearing.
Is there a reason you're doing these interviews? Were you hired or is this just done for you? Thanks, great videos :-)
I was not hired, Shell invited me to check out the event and make some videos on it. :)
Engineering Explained I see. Just curious. Keep up the good work. I enjoy these Shell videos. It would be cool to see you at SAE or AIAA events such Mini Baja, Formula SAE, or Design/Build/Fly which are competitions I was in while in college :-)
A good job but what could you do for 77 LTD or chev 350 engine in a full size car. Honda had 2 seat car geting 70 mpg years a go. keep up the good work some day they may use your system in racing.or on the road but to day this is only high tech toy
If you could get 50 MPG on the high way in those cars you would have done it the chev vega or ford pinto with the carb system did all right on the road but still had a long way to go and with all the high tech and light weight cars is the MPG all that good.
Keep up the good work who knows you make the next engine that gets 100 MPG
on the High way when you get out of school or drop out and do it. after all more than
one person has left the path and blazed a trail in the world.
That is amazing!!!
i wonder how efficient the motor is. 3500 mpg is extremely impressive for 89 lb car. but honestly its one thing to make a car lighter, smaller, and more aerodynamic, and drive at 20mph, but the real challenge is making the motor more effiecient. is the motor even at least as efficient as any other? we need to invent an engine that has zero nox and carbon monoxide
A 6 stroke engine might be used to further optimize the efficiency. Notice that the engine is insulated, perhaps a measure of keeping the maximum amount of heat generated by the gas combustion inside.
About 15-20% average efficiency. It comes down to rolling resistance and air drag + only running the engine at peak efficiency (burn + coast method). Laval's engine might a little over 20% efficiency since they did a nice job in that area of the car.
Whats the point in having a 1.9 horse power car when you can have a horse and its more fuel efficient where is peoples logic these days ?
You sir lack logic gretly.
Josh Herridge You'd only have one. That's .9 less. Plus you have to feed it, which is extra fuel, it's always running burning fuel, you can use it till it's a bit older, it needs taken care of. So many disadvantages.
@@joblessalex And the emissions...ooooh, the emissions...
I wonder what these cars could average in the real world in city driving.
They are not practical at all for urban road conditions. So they would probably break down before you could get an average mpg number. But it is awsome to see students work about effiency of gasoline and there are actually a lot of effiency clues to be used at commercial vehicles.
boost it
it couldn't do that in real life because hills, traffic and traffic lights exist.
That is basically true (if real life means on normal public roads), but it is not necessary for hills or traffic lights, to affect the efficiency very much. If you make it to the top of a hill, you can get most of your energy back by driving down the hill. And if you do not use brakes (you just coast to a stop), you do not lose much energy from stopping repeatedly, because you can save a bit of fuel by not running your engine as you slow down.
Legion Long not only that but recover some with regenerative braking
do you have a facebook page ?
So it's been 8 years since and my car still only gets 16 miles to gallon.
Québec city fuck yeah!
wow
I like EE a lot but what's up with the way Jason is interviewing this guy? Little to no eye contact with the camera nor the dude being interviewed, and he just keeps saying "okay." "okay." "okay...." maybe he has a little anxiety or something idk
Cla mmy Okay.Jokes aside, this was my second event ever. I'll get better with time! :)
Engineering Explained Your videos are amazing man - you've taught me a lot about how my Subaru actually works, and much more. I didn't mean any offense, you just normally seem so comfortable in front of the camera! Keep doing what you're doing!
@odombones94 I'm uuuh done
wow pretty amazing
so these guys can do 2800 mpg but gm,honda,toyota, and vw cant????
Its proving a concept. You would never buy a vehicle that would only go between 15 and 30 km/hr ish. Transports 1 person. And this is all tested on a flat surface with no traffic.
Bel accent hehe
turtles move faster than this car
Uhhh first of all we use uhhh gasoline uhhh for the uhh the fuel. Uhhh we are in category prototype. And uhhh the strategy we use it's uhhhh to have a lightweight vehicle uhhh reliability engine that consume uhh very low. And after that uh confident that very lightweight but strong enough to uhh tough the run............... Right here is uhhh the engine block....... It's uhhh 39cc.....I'm done..
He speaks French primarily, not English. But if it was in French I wouldn't understand, he was kind enough to translate for me. Cheers.
Would you rather he speak in French? I can almost guarantee that you would not be able to understand at all if he spoke in French.
Learn to respect others who speak more than one language. You appear culturally devoid.
Engineering Explained
Still, almost everybody under 30 can speak english pretty well (except for the french...).
vinigretzky97
Hahahahahahahahaha. Everyone under 30 from US and England maybe.
No in europe.
