Figured that would get your attention.
It might actually be true, though...at least for 0-60 times of new cars in 1991.
The 959 (0-100km 3.7) had ceased production in '89
Jaguar's XJ220 (3.6) wasn't released until '92
Ferrari F40 3.6
Lamborghini Diablo 4.4
Lotus Esprit SE 4.7
911 Turbo 4.8
Ferrari Testarossa low 5s
Corvette ZR1 low 5s
Am I missing anything?
..."Tuner" cars don't count! (Callaway, Koenigsegg, Saleen, Shelby Etc.). They didn't BUILD the car, they just saved you the trouble of buying one and tuning it yourself.
Let the debate begin!
