According to Edumnds.com:

Del Sol S curb weight: 2295 lbs
Del Sol Si curb weight: 2414 lbs
Del Sol VTEC curb weight: 2522 lbs

EG VX curb weight: 2094 lbs
EG CX curb weight: 2108 lbs
EG DX curb weight: 2178 lbs
EG Si curb weight: 2390 lbs

Obviously the EG VX is extremely light, but the Si is heavier than the S. Why aren't Sols used more for racing?
