That was the XP5 prototype, not the production road car that's in GT5. According to this source, Road & Track did a top speed test of a production road car back in 1999 and hit 217.7 MPH. So if that's correct it seems like the top speed in GT5 is fairly accurate.

There was a notable backlash when the Beetle was provided as DLC and weighed 600 pounds more than it should have.
Otherwise, none of the flagrant errors have ever been fixed, so I'm doubting PD even knows about them (or they did them on purpose, like with the LMP/Group C cars).
Because the gearing is wrong on the GT5 car.

PD does weird things with cars, not sure why the hp in race cars especially the prototypes tend to be very high, no idea what the reason for that was. McLaren F1 was never stated to reach 240 mph in it's regular street trim, you are never going to get there, in fact to reach the world record they had to equip with different tires and I believe allow the car to rev higher than it normally did. Showroom F1's could not reach such speeds even on a closed track without under hood tweaks that ordinary owners could do, professionals were needed. So as it is in the game it's quite correct, although not being able to change the clutch from that clunky and slow stock clutch hurts this car during shifts.
There are plenty cars with incorrect specifications, '02 Saleen S7 it's weight split is reversed, and a host of others. We should as a community keep pointing these things out so that PD will acknowledge it. GT6 with better community features should help us to relay information even better to PD team.

They might have mixed up the data, because there are restrictors involved. The Judd engine in the Pescarolo C60 for instance did 600+ bhp restricted and 800+ bhp unrestricted. Or they purposely went for the higher number to get a faster car, but forgot that the unrestricted engine revs up to 10 000 rpm (it does 7 800 rpm in the game, which is the same as the restricted engine).

If I had to guess it was in order to artificially balance them as being the top dog cars. Hopefully with a better physics engine they see no need to do that and return the cars to the true specs.

Let's hope the physics and all the new data fixes this. I hate trying to pilot those things without tcs as in low gears they require superb finger control. Another thing is how PD implements trigger sensitivity, it's weird and off, since before fully depressing the trigger I am always maxed out on pedal before perhaps about 20% of travel to go on the controller. We need ability to set the values and sensitivity and even make it vehicle specific.
Anyway I got away from my original point, I truly hope we don't have to deal with wildly overpowered cars, that power reducer thing is too useless as it doesn't map the power drop realistically enough to make sense. Probably expecting too much from the engine in GT6, but we might get a nice surprise who's to say. I tend to drive regular cars more than race cars anyway as it's always refreshing to tune and push then swap cars and totally smash the record with the previous car. GT6 will be my last PS3 game before plunking down on a PS4.
PD, no more overpowered Prototypes and Group C horse power ratings, please!

Actually it's because the car that did 240mph had different gearing, and the production versions could never actually reach that speed.
One thing that's been frustrating me for successive generations though, is that cars of older generations become able to produce less power with each new game. I distinctly remember having a 790bhp Nismo R32 on Gran Turismo 4, along with an R34 with about 830bhp, a BMW M5 with 725bhp, and a Z32 with about 800bhp. None of these cars now produce as much power as that, when in real life, with advancing car modification technology, they should infact be able to produce considerably more.
The list I could provide of cars that were able to produce more bhp in GT4 than GT5 would go on and on.

No it didn't. The car that did 243 (for the two way average of 240) had the rev limiter disabled with the stock gearing, making it run about 800 RPM higher than the stock 7500 RPM fuel cutoff. 231 was the speed that the car would get in 6th gear before hitting it. In GT5 the gearing is dramatically wrong, and the car won't even pull 6th gear stock; and since the car's 5th gear is at around 220 MPH that is the car's top speed in GT5.
In addition, the source posted above has many rather glaring inaccuracies contained (in addition to being a post on Supercars.net). It bases a sizeable amount of its premise on how the XP5 was faster than the production cars because the acceleration numbers were notably faster than those in the Road and Track test. The problem is that the Ameritech McLaren F1 that Road and Track tested in December of 1997 and the European McLaren F1 that the XP5 was the basis of (and is in GT5) differed by about 500 pounds.

They applied a straight power multiplier to all of the LMP, Group C and GT1 cars, giving them anywhere from 100-300 more horsepower and the same amount of lb ft of torque over what they should have. It was a choice made on purpose for whatever reason, because for most of the cars they have the correct stats on the purchase screen before you buy them (as I said above, I think it was for balancing purposes due to deficiencies the physics engines of the past couple of games).
The two diesel LMPs also have incorrect torque curves, and rev much too high.

And then there's the good old Volvo 240GLT that weighs about as much as it would with full trunk with backseats folded AND a full trailer on the hitch..

All we can do is to keep pointing at it and make it known, Kaz and PD will take notice as we have noticed that with GT5 they are actually listening to us and making changes that they could within the constraints of the game. GT6 is said to be a new engine that will allow for upgrading, which means that they realized that GT5 base engine wasn't so good in that respect. GT6 could be something changes all that we know about DLC and upgrading on a console, think of any additions later on down the line as beta tests for things that could become features or standard in the next GT game.
We just have to keep on them about it, in fact GT6 community features could allow for us to have PD check on the community and field discrepancies in the game. We don't know until we have GT6 in our hands but they touted improved community aspects so this could pan out to be nothing more than leaderboard or something greater to the point where we really get massive input on crafting GT to be something we can all say that we really helped mold and shape it to what will satisfy a vast amount of gamers. I refuse to give up on PD no matter how bungling they can be.

Reading all these posts makes me wish Gran Turismo was on pc! Can you imagine the thousands of mods and unofficial patches/fixes/addons this game would get?

Either way, the gearing is certainly wrong because the road going McLaren F1 that Road & Track tested was hitting the rev limiter (7,500 rpm) in 6th gear at top speed whereas the 6th gear in GT5 is completely useless -- it's not only unnecessary to ever use but actually slows down the car. The highest speed is only achievable in 5th gear.

We can dream. The biggest plus with PC gaming is the ability to fix the mistakes of the developers.
Another annoying busted thing is (was?) the inconsistent allocation of torque converter/ dual clutch transmission physics. The really annoying part was that only the DLC GT-R's was 'noticed' and resolved.
And some cars don't have correct engine RPM to actual car speed despite correct gear ratios and final drives. (E.g. 8C and V12 Vantage)
Could it be incorrect tire/wheel sizing? Or even inaccurate simulation of tire pressures and other environmental variables?
The odd part is that other cars have it nailed exact to specification provided by manufacturers or motoring publications. (The 2 Audi R8s for instance.)
