Nissan GT-R - Engineering Excellence

[rajasoumyajit]

the weight distribution of a GTR aids its cornering speeds. .getting fast times does not depend on how fast (top speed) you show .... its how fast u accelerate , brake and go around corners.. as a ZONDA n ENZO depends heavily on aerodynamic down-force, the density of air hinders with the gross handling of the cars.

and secondly when you are driving a car expensive enough as 16 GTRs .... even a madman will resort to his senses .

and finally " its the man behind the wheel ... not the machine "

[EngineeringExplained]

@rajasoumyajit Well the Nurburgring is certainly a high speed track, so aerodynamics would be in favor of the Enzo. And yes, expense affects the majority of drivers, but professionals drive cars far more expensive than 16 GTRs. A racing class vehicle's cost completely overshadows what any production vehicle may cost, so price wouldn't be an issue with these times.

[KalEl600rr]

All that science and my bike still shits on it.

BMW s1000rr ftw!

[isdisavailable3]

@KalEl600rr Your comparing a car to a bike? wow lol

How much less practicality do get from ur bike dude?

and it seems that ur bike is built for 1 thing, straight line speed.

the GTR has 4 seats in it that carry people in amazing comfort, has a MASSIVE boot and yet still does 0-60 in 2.9 seconds even though it was built for corning. yea mate you pretty much lost that.

[KalEl600rr]

@isdisavailable3 Practicality? My drive to work takes 10 minutes on the bike and 30 mins on the car.

And as for cornering

watch?v=VPNs3v4m7TA

and thats the slowest superbike class machine. your argument = dismantled

[3ua]

@isdisavailable3 You must still be living in 2005.

The BMW S1000RR was less than a second slower than the Atom V8 500 around the top gear test track. Faster than the 12c, aventador, veyron super sport, zonda f, gtr '12, enzo, 458, carrera gt, apollo s, GT2, atom 300hp and pretty much any other car you can come up with. And that on stock tires and stock suspension settings while the atom was on semi slicks.

Yeah, you lost that one gramps.

GTR is #1

[MoronAntidote]

The problem is that power to weight ratio only really tells you how a car will perform in a straight line, though obviously drag coefficient plays a part. Going into a corner, better brakes allow later braking, increasing average speed. Dealing with brake fade and perfecting ABS via technology help immensely. 4WD dynamic control technology improves speed through the corners, as well as corner exit speed, with much less reliance on driver skill. Driver pushes the tech to the limit with confidence

[hakeembisiolu]

There are two things that you kind of forgot to mention. Handling of the GT-R is amazing as stated above in like every comment but the fact of the matter is since it is hand built most GT-R do not get 485 HP. Most get actually much more and nissan has a habit of underselling their engines. There are actually some 2010 GT-R on the road that have 530 whp stock, which is alot for all wheel drive.

[EngineeringExplained]

@hakeembisiolu This is true, and I didn't mention it. Knew it would come up eventually. And 45 hp will make a big difference, but even if you say this car had another 45 hp, it would still be at a clear disadvantage from a power to weight ratio. Basically my intention of this video was to show that you don't necessarily need a ton of power if you want good track times. Japanese engineers have figured it out. Others are a tad (or a lot) behind.

[JohnsonBarry]

Awd is a major piece to the puzzle, the gtr has grip and exit speeds unmatched by other cars. Check out the Evo x as well, I bought one since I couldn't afford the gtr yet look at my review video.

[BicZippo]

Sorry to double post but I have to say that this car is also very easy to extract maximum performance where as other cars require more driver involvement at 10/10ths. cheers

[BicZippo]

Great video! Its a combination of the amazing AWD system combined with the quick shifting dual clutch gearbox, and notoriously underrated motor. The sensors this car has and the algorithm used to manipulate power delivery to the individual corners (wheels) has never been done before in a street car which make this car seem more like magic then engineering. All these thing combined deliver power to the ground in a way never seen before in a road going car. Please continue the great work :)

[djruido1]

23 rules!!!! if any knows haha (Nissan)

[djruido1]

The AWD also looses power by trying to move all four tires.

[MrCarGuy20]

Btw you compared an AWD vehicle to multiple RWD vehicles. It is no magic that an AWD car can far exceed RWD in the handling category. It's simple: AWD=more traction to the ground, especially during the corners.

[MrCarGuy20]

The 2013 model adds 15hp to the 2012's 530hp.

[bmlotkowski]

I love learning every day. Subscribed, keep up the good work

[impeccable24]

the awd on the gtr is ridiculous

[RMS13JACOB]

@EngineeringExplained Oh no, I'm just getting into university. Have you ever heard that a formula one car could theoretically drive upside down(on the ceiling) due to downforce, or negative lift? Do you think a scaled down version of the test would provide similar to realistic results?

[EngineeringExplained]

@RMS13JACOB Yes, and yes. Definitely possible.

[RMS13JACOB]

I love the videos. How far along in school are you?

[EngineeringExplained]

@RMS13JACOB I graduate in May. You know of a job haha?

[kabamm900000]

AWD .. handaling is the key factor here lol... the only way tht ur theory or w.e. would be impressive is on a drag trak buddie... sooorrryyyy... but .. u cant make horsepower and weight the key factor. u need handaling and traction to put power to the ground

[EngineeringExplained]

@kabamm900000 Oh wow, hey thanks, now I know...

Handaling. That's what I was missing.

[Truthseeker182]

I'll tell you how it's possible.

The AWD. System in this car is is the most sophisticated in the entire world.

The way this thing transfers power between the tires is just incredible.

And you forgot to mention the TwinTurbo. That thing spools up so quick :).

I love this car so much.

[EngineeringExplained]

@Truthseeker182 You're right about the sophistication. Those darn Japanese, always showing how it should be done! Such an incredible vehicle.

[stebs1690]

NEEESAAAAANN

[EngineeringExplained]

@stebs1690 Something wrong?

[joeslimon]

I think he's referring to the added weight that awd systems give to vehicles?

[JETZcorp]

I tend to think the Porsche 911 Turbo is a bit more magical than the GTR. What makes the Porsche special is that it has some fairly similar stats to the Nissan (albeit with a bit less weight) but the engine is in the back, which everyone keeps saying is a bad thing for the car's handling, yet it remains a supercar benchmark.

By the way, the 2012 911 Carrera S, with less than 400hp, just nearly matched the previous 911 Turbo's lap time at the 'Ring. The next Turbo ought to be insanity.

[EngineeringExplained]

@JETZcorp There are advantages and disadvantages to a rear engine. Better braking and acceleration. The problem is with all the weight in the back the cars moment of inertia about the vertical axis (straight down into the car) is high, meaning the car doesn't want to rotate. If they improved the cayman more, other cars would have some fierce competition, but it seems like they don't want anything better than the flagship, which makes sense.

[NissuTSX]

It is indeed and amazing car. It's Japanese. That says everything :)

[azulcrema06]

i enjoy watching all your videos. respect and thanks for the info. i hope you keep making more videos.

[spartanfootball27]

2011 Porsche 911 Turbo has 7 lb/bhp (500 bhp, 3500 lb) and has a 0-60 around 3.2s, kind of the same anomaly. Turbo S, not quite as much with 6.3 lb/bhp and a 0-60 of around 3s.

[b00beezz]

wow your videos are absolutely amazing. very informative, to the point and very easy to digest. Good job man!!!

[juliannevillecorrea]

@EngineeringExplained help..ci combustion delay and reducing knocking... my freind is rebuilding his diesel motorbike ... thanks..

[juliannevillecorrea]

@JohnnyDeniz help..ci combustion delay and reducing knocking... my freind is rebuilding his diesel motorbike ... thanks..

[jy0408]

Your videos are wonderful. Could you make a video or the entropy relations of each state in internal combustion engines? For instance, could you explain why we use Gibb's free energy term for the calculation of the engine's efficiency(Efficiency_engine=G­ibb's energy term/Low heating value of the fuel) etc. Thanks in advance. By the way, you are really good at explaining stuff. Keep up the good work!

[EngineeringExplained]

@jy0408 Thanks! My thermo teacher didn't seem to be fond of Gibbs (not sure why, we spent little time on his equations). We did however analyze thermal efficiency (both Otto and Diesel), volumetric efficiency, and mechanical efficiency in depth. Perhaps I can make an analysis video going through all the engine cycles and calculate efficiencies in the end. And I'll look up what I need to know on Gibbs.

[ThePustr117]

Asians are good at everything.... i wish i was asian, minus the rice

[madass888]

All the exotic super car engineers must feel like idiots. Their cars gets powned by a fourseater wich costs significantly less.

[360mmspider]

i have also thought of the GTR has the best bang for your buck. high end sports car. i never put the time into what you just said. thanks for the info. it really does make sense.

[thekkl]

One of the reasons it's possible is because you're looking at peak horsepower, which isn't fair to the GTR's engine, which may not have that high of a peak power rating, but has quite a fat powerband.

And as for comparing the GTR to the Vette, it's more fair to consider price then to compare power and weight when deciding if they should be compared since you can have two cars with the same weight and power but one was designed with much more money put into performance and it will be way faster.

[hfsdsdfsdgasdfgaf]

Because it's built by Japanese ofcourse!!!

[joeslimon]

The GTR is pretty good, but your analysis is too heavily focused on the power/weight ratio. The GTR is quick mainly due to its torque vectoring awd setup. None of the vehicles you mentioned have awd or torque vectoring. Also, compared to the Atom, higher horsepower will prevail at higher speeds due to increasing drag forces. Which is why the Veyron can be so portly yet have a higher top end speed then cars with much better power/weight ratios.

[sheennick12345]

@joeslimon I would also like to add that on the track handling of the car also makes a major difference in the lap times and the japs as you would expect from them have done a phenomenally excellent job of making the onboard computers do the job...

its not always about how much power you have ...but more like how much you can put down on the road...and thats where nissan shines

[zozlimits]

@joeslimon yes but add actually is worst for a track, these are lap times so the gtr is at a disadvantage

[zozlimits]

@zozlimits AWD* sorry 

[EngineeringExplained]

@zozlimits Could you explain why AWD is a disadvantage on tracks (or anywhere)? Sure, it's more friction, and at higher speeds it's much tougher to accelerate. But AWD allows for the maximum possible amount of torque at any time. You can't floor it below 40 without awd and expect no wheel spin with 500 hp at peak rpm. Around the corner, the torque goes to the tire with the most grip, not the tires holding the car around the corner. I'd just like to hear your reasoning, that's all.

[zozlimits]

@EngineeringExplained i always was told when cornering add gives a car a disadvantage because of handling thats why i thought ferrari and lamborgini and some other track focused cars didn't use awd. maybe I'm wrong my friend told me 2wd on a track is always best all the time but fell free to prove him wrong lol

[EngineeringExplained]

@zozlimits AWD adds friction and weight. RWD is great because weight transfers to the back, however AWD allows the most torque to be applied to the tires at any given time. Also, the majority of Lamborghinis are AWD.

[zozlimits]

@EngineeringExplained most lambs are awd? i never knew that but thanks so what would you say is better

[JohnnyDeniz]

Can you make a video about rebuilds or talk about the torch specs for the engine casings and more detail about intake valves

[EngineeringExplained]

@JohnnyDeniz I can make a video on valves no problem. What information did you want specifically? Like differences between dohc/sohc/pushrod and how the valves relate? Also I do not know much about torque specs on engine casings. As far as rebuilds, what did you want to know? Thanks for your interest!

[iDunnoYuTellMe]

Great analysis and thank you - i've never thought about the GTR like this. You're the best, keep the videos coming!

[EngineeringExplained]

@iDunnoYuTellMe Thanks! Just started back in school, so it'll be a little more spaced out now, though I've got an automotive engineering course and another on internal combustion engines.

[iDunnoYuTellMe]

@EngineeringExplained ahhh thats gay. What do you want to be when you grow older? I'm thinking of becoming an automotive mechanic (repairing cars and stuff at a dealership) but I've heard the pay isnt good :\ btw - you have a lot of my respect for these videos, they deserve much more views.

[EngineeringExplained]

@iDunnoYuTellMe You may start off not getting paid well, but after 10 or so years at a dealer, you could easily start your own business, and make much better money (and do it in a more honest and helpful manner). I hope to work in somewhere in the automotive industry. I have no specifics other than that. Anything from Fiat to Pagani hahah

[Beef1188]

@EngineeringExplained The GTR is nothing less but a masterpiece of automotive technology, a true mona lisa of the sports car world.

Unfortunately its a bit of a gas hog. I rented one for a day because I was curious and during that time I blew 180€ worth of gas. I'd say it was worth it but owning one would be ridiculous.

[dxb8788]

Cornering machineeeeeeeeeeeeee

[valcked]

... the new car ditched 4w steering to reduce complexity and drop some weight.

A car is as it is ... some are very light (Atom), extremely powerful (Corvette), have great down force (Pagani), etc ... they are choices makers make and give cars there particular look and character. So, a GTR has 4WD, 4 place, 6 cylinder 3.8L engine, it weighs 1800Kg, has a DragCo of 0.27-0.26 ... it is what it is, so for some, appreciate what was made.

And any person can go fast in it ...

[valcked]

Great you put the video together, and for conversational purposes a very good comparison.

... as I have a GTR ... it also has 4 places and a big boot!

The GTR can move its torque from 0-100% to 50-50% over the length of the car, then it also has per wheel torque vectoring allowing it to push harder on the outside rear and front wheel when cornering. So when you turn left, the outside right-hand side wheels put more power down, helping the car to turn. The Skyline GTR R32-34 had 4w steering.

[vgdd4]

Good analysis

[StevenSWM]

Was wondering...do you know if all this data collected on these cars was using the same track (same kind of pavement), using the same driver? And I suppose the tires were not the same type tires, but tires inherent to the cars themselves? Also, the GT-R is a 4WD...but are those other cars?

[EngineeringExplained]

@StevenSWM Same tracks, both Nurburgring and Top Gear's test track. Tires were all different, but to my knowledge none of the cars were using slicks so grip is comparable for each car. The other cars are not 4WD, they are all RWD, however Nurburgring is a high speed track, and at high speeds grip is comparable for both 4WD and RWD. Also, 4WD tends to cause mild understeer, as well as reduce excessive speeds because of the added friction.

[nerdypielover]

I never really thought about this myself, i do believe its the cornering speeds and all the stuff they use to enhance it, via electronics, and other stuff like that,

[EngineeringExplained]

@nerdypielover Yes, it does corner very fast. Though by the numbers its lateral grip doesn't seem too impressive. It seems that it can switch directions and not lose grip as much as other vehicles though. Respectable.
