this car is a clear example of people using exploits to get ahead. How can a 1991 car (almost prehistoric) beat new prototype cars with next gen innovation and some of the most sophistcated designs?!? It’s so unrealistic. This car needs to be toned down a notch or two seriously. I’m tired of leading a lap in a prototype car that I spent hours of racing in to fine tune the tune setup to squeeze that time hundredths of a second at a time, just to be beat by someone who simply download a top rated tune and completely destroy my lap times!!! Please fix this it’s really getting on my nerves. I should be getting rewarded for the hours i spent tuning vs someone who downloads a bs exploited tune for the 787b. Sorry if I offended anyone, just needed to get this out there
No disrespect but maybe the other guys a better driver?
No I understand it’s entirely possible that they may be however I’ve been playing forza since forza 2 and I’ve been especially focused on the prototype cars throughout the years so I know my way around tracks very well, but when some low driver level kid with his kinect mic on manages it pass me it’s extremely frustrating. And it to me is almost like they are the dirtiest racers , cutting corners, crashing into me on purpose and not allowing me to pass when they mess up. I’m not saying that every person that uses the 787b is a dirty racer, but the majority are.
Since 1991 there has also been a lot of rules to make the racing a lot safer. Maybe that’s why the mazda is still able to beat the modern cars
That is a good point, my only question is what exactly did they do to make it safer ? If they wanted it to be safer wouldn’t the car be slower ? Like adding extra safety precautions which would add weight, or maybe less engine power so drivers aren’t at extreme speeds more often than not?
I was looking for actual laptimes of the 787 on lemans, and a modern LMP1 car, but I cannot find anything about the laptimes 
The chicane layout was used in 1991, so although some changes have been made in the past 15 years, you can draw some sort of conclusion from qualifying laptime comparisons:
1991
Fastest 787B: 3:43.503
Fastest Peugeot 905: 3:35.058
2014:
Fastest Audi: 3:23.271
Fastest Toyota: 3:21.789
Try comparing those laptimes to ones set in-game with similar cars using stock setups.
The game simulates it poorly to make it one hell of a monster. But if you look on the boards, it’s not invincible. There are Bentleys up there on speed tracks, etc.
The game does give it a hell of a lot of downforce and not only that, so much mechanical grip too. And that’s on top of its lower drag coefficient. If the other cars could build up into P 998 rather than P 990 something then they might have had more of a chance.
As I’m probably someone who has the top tunes and sets a few top leaderboard times, it is quite annoying that they haven’t balanced the cars or given opportunities to optimise them properly.
One thing I noticed, and your post reminded me, the 787b’s ratings like handling, speed…etc, are far superior than for example the R18. However the R18’s PI is 997 and the 787b is a few lower, but yet the Mazda has all the dominant ratings. That to me makes absoulutely no sense. Like does the ratings mean anything?
The game gives it the same race rubber as anything else, which may buff it more than perhaps it should. But then it also has so much downforce, the same as cars 10 years further down the line, and nearly as much as today’s, that it corners as good as anything. And that downforce and sticky tyre compound will give it acceleration, more so given that it has a healthy amount of power to boot. Today’s LMPs, and those this side of 2010, are the fastest we’ve ever seen at Le Mans, even with course adjustments!
Realistically, given the game’s control variables like tyres, brakes and all that, the Mazda should be a speed track king. But it has too much of everything so it dominates where the Audi/Toyota should easily walk away.
The game is just inaccurate in some of its simulations.
Perfect explanation thanks man. Makes it a little clearer.
When upgraded the Mazda 787B is fair superior to most of the other cars, heck it only won Le Mans in 1991 because it spent the least time in the pit as it wasn’t the fastest! That however isn’t upgraded. The very confusing thing about the 787B is it’s immense amounts of grip for a car with very little aero kit. Yes it has a large wing and big tyres but that doesn’t exactly account for the grip levels.
In truth many, if not all, of the Prototype cars are broken. The Group C (787B and 905) are stupidly good and way out perform what they should be, in fact in Forza 4 all the Group Cs were crazy good making the modern cars look like a repeat of the 1 Million dollar US space pen when a pencil is all you need, with the exception of Porsche 962c (another Group C car) was appalling and yet in real life it dominated the Group C era and even the early GT1 and LMPs(!). Other broken cars include the Toyota TS040 which has a missing 200 horsepower and so the Audi R18 from the same year easily beats it while it was quite the contrary last year and the Rebellion R-One LMP1 (or Toyota Lola R-One as it’s called) is in the same ball park as the Mazda Lola which is a Prototype 2 car, granted it runs in the USCC Prototype class so it may be faster to compete with the Grand Am cars) but still.
It seems like some of them are a bit off from what they should be and yes the 787B is way, way too good for what it should be, fully uograded it’s only 995 and it’s giving the 998 cars a real **** whooping!
Thank you! You know your stuff. Hopefully down the road this 787 and 905c bug will be addressed, I have noticed a slight increase of these Prototype cars in hoppers, I remember back in the day with 3 other people in the lobby and now there is a solid 20 people regularly in a lobby, this being said maybe T10 will put a little more effort into these cars. We just have to wait…another year .
If they put the same effort into Prototypes as they did in FM4 where you had a decent few cars that weren’t half bad, they’d be mint. Of course the Sauber came and stomped everything but before that, the Acura ARX-01b was quick enough on small handling tracks, and the ARX-02a was alright at the medium speedier tracks. We need a couple of cars like that to take on the Mazda.
