[redyaris]

The Yaris is aprox 1200kg and the GS500 is aprox 300kg both with the driver/rider. The estimated Cd of the Yaris with aeromods is Cd=0.27 and the estimated Cd of the aeromoded GS500 is Cd=0.5 - 0.6. with respect to frontal area the Yaris is 2.5 - 3.0 time larger. Subjectively on a down hill section of road the yaris will start at the top of the hill at 100km/hr and be going 120km/hr at the bottom of the hill EOC. The GS500 on the other hand will start at 100km/hr at the top of the hill and will be going 90km/hr - 100km/hr at the bottom EOC. I can only recall 2 or 3 times when the GS500 gained speed going down hill!
