So I was curious as to how acurate pd made the cars in the game in relation to real life. Heres what I factored in: Horsepower,torque,weight, weight ballance, gear ratios, tires. My test car was the 2009 Chevrolet Corvette ZR1.
Stock specifications are as follows for the real life car.Horsepower:638Torque:604 Gear ratios (:1): First: 2.29 Second: 1.61 Third: 1.21 Fourth: 1.00 Fifth: 0.81 Sixth:0.67 Reverse:3.11 Final drive ratio:3.42 Curb weight 1519-kg/3348.82-lbs. The weight ballance is 51/49 or 51% in the front and 49% in the rear.
Now for the gt5 Zr1. When I bought it the power and weight was slightly off. The dealership shows the correct power numbers but the weight was less than the real life car about 11kg lighter. After I bought it, it didnt come with the power numbers shown in the dealer, it came with much less I think only 612hp even though it says 638. So to make up for this I decided to see if an oil change would make it go the correct power only to find out that it makes it too powerfull at 650hp. I did not do the oil change because I know that will raise the torque as well and you can bring torque lower by adjusting the engine power %. So by surprise i installed the sport intake manifold and racing air filter which brought the power of the car to 638hp and 604ft-lb. The rpms of the these number also stayed the same. Now lets move on to weight. Like stated earlier the gt5 car is 11 lighter than what it is in real life so I added 11kg to make up for it. Now the weight ballance was also not correct. In real life its 51/49 but in gt5 its the opposite 49/51 very strange huh. Also the transmission gear ratios in gt5 were all correct.
Now the real fun begins, testing the following numbers comparing real life vs gt5. I have tested 0-60mph, 0-100mph, and 1/4mile times. The real life times I found from various sources are as follows: 0-60mph 3.2-3.4s 0-100mph 7s 1/4 mile 11.2-11.3s Trap speed around 130mph. Using route X with an automatic transmission I got some interesting results. Soo as you all should know by know high end cars in gt5 come with sport hard tires. When I tested sport hard tires the times in gt5 were way slower than the real life times as an example I couldnt even get under 3.8s 0-60mph at 0.74gs using various launches. So I moved on the sport medium. These were also slower, I couldnt get under 3.5 0-60mph at 0.82 gs. Now for sport soft. using these tires I was able to match all times in real life. The sport soft tires numbers are as follows: at 0.89gs 0-60mph 3.2-3.4s 0-100mph 7s 1/4mile 11.3s. With a black screen launch only the 1/4mile was off at 11.403s but the 0-60/100mph stayed in the real life number window. Timed launches at different rpms produced much lower times compared to the black screen launch but all remained in the real life number window. The fastest 1/4mile time I got was 11.300.
Again I used an automatic transmission and no aids, completly stock except for those 2 upgrades to make the numbers correct and of course adding the sport soft tires. In conclusion I think that in order to get true to life physics (at least in a straight line) is to use sport soft tires on productions cars. Congratulations to Polyphony Digital for creating such a true to life experience in a video game! I think I am going to test other cars too including different drivetrains to truely see the accuracy of gt5, so far its looking pretty good. Also heres some pics.
