After being surprised of the braking performance of the Elise (incredibly bad) and the SL 500 (incredibly good), I did some testing : The brake tests were done on Fuji, I drove to the first corner, returned, and accelerated to a constant speed of 150km/hr. At the start/finish line, I did a full stop with several cars. After the finish line are the starting positions, which allowed me to "measure" the brake distance from 150km/hr to a full stop. Every test was repeated at least once. 1. Lotus Elise - weight : +/- 700 kg - distance : 5 lines and 2 car lenght 2. Mercedes SL55 AMG - weight : +/- 1800 kg - distance : 4 lines and 2 car lengths 3. Impreza 2003 - weight : +/- 1300 kg - distance : 4 lines 4. Impreza 99 - weight : +/- 1200 kg (in any case lighter then the '03 version) - distance : 4 lines and 1 car length 5. Integra 98 - weight : +/- 1100 kg ?? - distance : less then 4 lines 6. NSX 97 - weight : +/- 1200 kg ?? - distance : 4 lines and 2 car lengths Conclusions --- 1. The lightest car needs the longest brake distance?? 2. The SL55 stops as fast as the impreza, which is 2/3 of its weight?? and faster then the Elise, which is +/- 1/3 of its weight?? Is Polyphony Digital joking with Newtons Law here?? 3. The newer Impreza stops faster then the older, allthough 100 kg heavier : Result of the improvement in technolgy the last years? I'd like to see this confirmed in a R/W test report 4. The Integra 98, however one of the "older" cars, stops very well. Was the braking technology then not so bad by all a few years ago? 5. The NSX is also braking bad. Should the mid-engined cars get an artificial penalty here by PD? The weight distribution in these cars is better then in most other cars, so the brake forces should be better transferred to the ground. Mid engined cars are supposed to stop better, not worse!! Another physics law screwed by PD? 6. The Xanavi GT-R and Takata Dome NSX were tested at 150 and 200 km/hr : both with the same braking performance - 150 km/hr : 3 lines - 200 km/hr : 5 lines Any comments, or real life data to compare this? Btw : the weights are approximative, but the relations won't be to far wrong.
