It has been months since I have played GT5 (my ps3 is at home :( )...so I don't know if there are any changes made to the cars in general in terms of speed and what not.

Anyway, a few months back, I test drove both cars - your generic NASCAR sprint car and a generic SUPER GT (saying generic because I don't remember specifically what cars I drove lol). To my amazement, the sprint car actually got a better time at the short track at Suzuka as opposed to the Super GT. The time between the two was relatively close but my times for the sprint cars are always consistent.

I admit, I have yet to take these cars on the other tracks but was wondering perhaps others have already tried this experiment with many results.
If anyone has done a series of tests and experiments on both cars, please do share and give your opinion on which is faster. 👍
 
The NASCAR has about twice as much horsepower, that's probably why you were faster. It also handles good for being such a big and heavy car.
 
I've never thought of comparing Super GT GT500 cars against Sprint cars. Of course, one thing you need to consider is to not run the 300hp+ GT300 class car against the Sprint cars.

I'll run a couple of tests on one or two tracks that demanding enough to test both power and aerodynamic (including downforce). I'll post the result.
 
Nah, I actually used the GT500 class. I remember there was a debate over some other forum about Super GT vs. FIA GT1 cars. In general, at Suzuka, the Super GT cars would lap the track about 2-3 secs faster (correct me if I'm wrong). But the problem I see with this is that aren't all Super GT cars honed at the Suzuka track most of the time anyway? I know they have raced at the Fuji raceway but it seems like most of the videos showcase the cars at Suzuka.

Either I underestimated the sprint car's ability to turn that well or maybe the PD team just somewhat "overlooked" the car's true abilities.

Don't get me wrong, the sprint cars are fast race cars but I figured they are most of the time the kings of 200+mph endurance machines. :scared:
 
I'm not sure about the tire specs for Super GT, but I know the major drawback of a NASCAR COT is that it's tires are thin. If the tires are relatively the same, however, then it not that far to see how the COT is as fast as a Super GT car, considering how much downforce the COT has with the front splitter, real spoiler, and the shark fin on the side.
 
I did the same test a couple of months ago (not seriously though)

on Fuji GT, the impala was faster than the cerumo supra, but I did not do many laps in either. Assuming similarly advanced cars, the GT500, being lighter will always be a bit more agile. The NASCAR, being much more powerful (power to weight and power only) will always be faster when cornering limits are not reached (slight bends). So Fuji, Tokyo, Sarthe and some other tracks will give a significant edge to the american. Try autumn ring mini now...

You will get different results at different tracks. At such a fast track like Suzuka, the extra 400 horsepower is hard to overcome no matter how well the SuperGT cars can handle.
 
Downforce and tire grip aren't simulated all the well. the result is the NASCAR keeps it's speed bust doesn't suffer too much in terms of handling.

This.

If you pump up the downforce on any NASCAR race car, it will handle pretty muy like any other lighter more agile race car.
 
The question is...Which would be faster round an oval if the cars had the same hp. I think the gt500 series cars. I took one round indy and didn't have to brake or let off once.

I think it would be interesting.

The COT NASCAR's create a lot of drag because of their big fat front end. At the same time, they're streamlined purposefully for this type of racing.

The GT500 car will have far more downforce which creates drag, but the natural shape of the body is also much more streamlined to start.

Who want's to be the tester?
 
i am going to do something soon and take all of the race cars around nurburgring and then i will post the times here
with the same tires and everything
i will also do this with street cars and mini cars
i love pitting cars against each other to see which is better
 
Around the Nurburgring it won't even be close. The GT500 car will walk away.

Do the test around Daytona with equal Horsepower and proper gearing.
 
Straight Line = NASCAR wins
Curvy bits = Super GT wins

The aerodynamic modifications a SuperGT car undergoes is simply out of this world. A Maserati MC12 didn't competed at SuperGT because it was 2-3 seconds a lap slower, due to it's "conservative" aerodynamics. Also, they're veeeeery light, which means quick acceleration and superb cornering. I don't know for sure , but I got the sneaking suspicion PD made NASCARs better than how they are really. A car so heavy and so powerful just can't corner that good, at least to me.

On a twisty track, my money goes to the SuperGT. On any course with a long straight the 300HP advantage of the NASCAR will even things up, or even take the checkered.

Race a Super GT against a Nascar at Monaco :)

I woulnd't want to be a barrier in Monaco when I saw a big phat steel car coming close to me :scared:.
 
I did a quick test last night on both Monza (without Chicane) and Nurburgring GP track.

One thing to consider with the Sprint car. The skidpad test number for Sprint car is usually around 1.15g although there have been fews that tested lower and while that's higher than most supercars, it is much lower than FIA GT1 cars and therefore Super GT cars. I don't know the exact number for Super GT cars but they're in the vicinity of GT1 cars which measures at 1.7g (although it might even be slightly higher for Super GT GT500 cars, equivalent to LMP2 cars).

If you use the tire calculator for GT5 (found here: http://bit.ly/o44zkc) with the 1.15g measurement the equivalent tire is Sport Soft.

Basically, in order to get an equivalent real life grip performance from Sprint car, you need to use Sport Soft and not Racing tires. However, the 1.7g for GT1 or Super GT cars, Racing tires is definitely the choice.

Once I got the tires sorted out the test went accordingly. For Sprint car, I use the Toyota Camry and for Super GT, the Lexus SC430.

For setup, I leave both cars close to its default setup. ABS are turned OFF since both FIA and NASCAR doesn't allow any traction and stability control including ABS. On both cars the strength and brake ratio are set at 4(F):2(R). The FFB on my G25 is set to maximum 10.

For the lap- I did a few casual lap to familiarize myself with the cars. The it's a three lap time-trial. I heed to the basic TT rules- to keep two inside tires on the track at all times especially in corners and tight chicanes.

The results are as follow:

Nurburgring GP/F:

2010 Joey Lagano #20 Camry (SS tires for equivalent RL grip)- 2:05.131
" " " (RH)- 2:03.761

Petronas Tom's SC430 '08 (RH)- 2:01.627

Monza (without Chicane)

2010 Joey Lagano #20 Camry (SS tires for equivalent RL grip)- 1:41.459

Petronas Tom's SC430 '08 (RH)- 1:41.887

Great test. It confirms what has been discussed in here, the more the turns the worse for the NASCAR.

Bonus points for the research on tyres. It kind f confirms as well my thoughts about NASCARS being too fast on corners for cars that weigh so much. Could you please share your source for the 1.15G number?
 
I did a quick test at the Nordschleife ... one hotlap in a NASCAR and one in a Super GT. I fully expected the Super GT to blow the NASCAR out.

My NASCAR had 892 hp, 567 tq and 658 pp, downforce maxed to an utterly ridiculous 50-70, racing hards.

My Super GT was the Takata Dome NSX '03, which is my favorite NSX of the ones I've used extensively. 511 hp, 330 tq, 596 pp, downforce maxed to 35-60, racing hards.

Firstly, how can a NASCAR have more downforce than a Super GT? That's just stupid. The cars are built to go around and around an oval all day long.

The only other time I had a NASCAR on the Nordschleife was for the Seasonal Event. This Takata Dome NSX '03 I've put in many laps there.

Well, from the first corner I knew the NASCAR was going to put in a good time LOL. I am either totally underestimating NASCAR or the ones in this game are total BS. Car weighs nearly 1600 kg and you don't feel it at all under braking or in the corners? Come on.

Anyway, my time in the NASCAR was 1.2 seconds faster than my best ever time in the NSX, even displaced it from the leaderboard, LOL. Uh oh, so I knew I had my work cut out for me on the NSX hot lap.

Luckily I pounded out a lap that was 5 seconds quicker than the NASCAR, my new record the for the Takata Dome NSX '03. :)

Hardly a blowout I would say, but that has to speak to the NASCAR being just stupidly unrealistic for GT5 purposes. No way that thing is going around the Nordschleife that fast. My NASCAR topped out over 200 and a good 20 mph faster than the NSX on the straight, so it made up lots of time there, but still ... I'm just glad my Super GT won, but I bet if I practiced with that NASCAR I would close that gap down. Then again I'm also sure there are faster Super GT cars than the '03 I was using.

ABS 1, all other aids off for both.

The adjustable downforce doesn't take in to account the natural downforce (or lift) generated by the car's body so the numbers in the tuning window aren't the whole story of the car's aerodynamics.

It appears to me that my suspicion is confirmed again, NASCARs have apparently been pumped up by Polyphony. Maybe a perk of the NASCAR contract, but who knows.

I still find it difficult to believe how a big lump of stock car can be, according to GT5, more aerodynamic than a SuperGT. I mean, look at a picture of them both and try thinking which one produces more drag, which one handles better the airflow, etc. The SuperGT cars are lower, have ridiculous 3D wings, have complex diffusers fore and aft, canards, the lot! I'm not saying NASCARs suck, but surely they can't be equal or better at cornering than a SuperGT.
 
I wager that GT500 cars actually generate more drag than NASCAR. Big wings and bodywork that looks like the car had encountered an axe murderer at some point of it's production is prone to do that... :P

I think PD just screwed up on the tire physics. When Good-Year makes tires for NASCAR, they use tires that are really hard, because if they're too soft, the tires tend to explode, However, by PD allowing the COTs to race on softer tires that don't explode, they significantly increased their times.

The problem with this test is that first you're assuming that both Sprint car and GT500 cars have maximum lateral grip. They don't as I've pointed out earlier. And secondly, neither series allows ABS which means you want to turn the ABS to "0" not 1. And I would also assume, GT500 cars will have a much stronger brakes than Sprint car.

Try running the same test again but this time using Sport Soft for the Sprint car and Racing Hard or Medium for Super GT. That result will probably be a better indication of what the car should be performing on that particular track.

I think PD just screwed up on the tire physics. When Good-Year makes tires for NASCAR, they use tires that are really hard, because if they're too soft, the tires tend to explode, However, by PD allowing the COTs to race on softer tires that don't explode, they significantly increased their times.

Which is the reason skid pad test for Sprint car are only slightly better than supercars in the 1.08g to 1.15g. If you use the GT5 tire calculator (I've posted the link earlier) which gives you the best tires in relation to a car's skid pad test, the right tire choice is actually Sport Soft and not Racing tires.

But essentially if you want to compare the two series, based on the maximum lateral grip for the Sprint cars and GT500 race cars, for the latter you need to use softer and grippier compound. For example, if you insist on using Racing tires for the Sprint cars (and not the Sport Soft), use Race Hard for it and use either Race Medium or Soft for the GT500 cars.

Most people have a tendency to assume that Sprint cars just race on oval tracks and are not competitive or fast on regular race track. Just a few weeks ago they had the Nationwide series at Road America. When these cars are set up for race tracks, they can be fast. The fastest car at Elkhart Lake (another name for Road America) was the Ford driven by Billy Johnson' at 2:14.871 followed closely by Jacques Villeneuve at 2:14.938. If you look at last year's result in the GT2 class in the American le Mans series (ALMS) at Road America, the fastest car was the Corvette ZR1 (driven by Oliver Gavin) at 2:08.014. That's just 6 seconds for what is a really long and demanding track. And the Sprint car was faster than the ALMS' GT-C race cars (that's GT Challenge series of mostly Porsche 911 Cup series car) by 1 second. So don't overlook the fact that close to 900hp makes a huge difference especially when these cars are setup properly.

One a road curcuit, Super GT cars are a lot faster than NASCAR cars.

But when it comes to top speed, nothing can beat a NASCAR car (ok, an Indycar car could....and a dragster :D ).

One thing to consider with the Sprint car. The skidpad test number for Sprint car is usually around 1.15g although there have been fews that tested lower and while that's higher than most supercars, it is much lower than FIA GT1 cars and therefore Super GT cars. I don't know the exact number for Super GT cars but they're in the vicinity of GT1 cars which measures at 1.7g (although it might even be slightly higher for Super GT GT500 cars, equivalent to LMP2 cars).

If you use the tire calculator for GT5 (found here: http://bit.ly/o44zkc) with the 1.15g measurement the equivalent tire is Sport Soft.

Basically, in order to get an equivalent real life grip performance from Sprint car, you need to use Sport Soft and not Racing tires. However, the 1.7g for GT1 or Super GT cars, Racing tires is definitely the choice.

I want to know where you got 1.15. When I googled it the first two with actual lateral-g figures were 1.9 and 1.8.
 
The problem with this test is that first you're assuming that both Sprint car and GT500 cars have maximum lateral grip. They don't as I've pointed out earlier. And secondly, neither series allows ABS which means you want to turn the ABS to "0" not 1. And I would also assume, GT500 cars will have a much stronger brakes than Sprint car.

I was not assuming anything, it was just a direct comparison of the cars on stock tires with max downforce. I may do it again with default downforce ... in which case I think the results will be more in favor of the Super GT car.

As for ABS ... braking in this game is nothing like reality. What they call "ABS" is not an ABS system like in a real car or racecar. IMO, the game can't simulate braking accurately so they have the "ABS" aid. Until they have accurate force feedback brake pedals, the braking in this game is just an educated guess.

ABS used or not used in series X or series Y has nothing to do with the reality of actual braking. Most street cars don't go skidding under light application of the brakes at 100 mph like they do in this game with ABS off.
