The Smart Diablo runs in a super tuned Suziki Hayabusa 1260hp, and does 0-60mph in 3 sec , thats faster than the bike because it is 80 kg lighter then the bike, the car weighs less than 600 kg!
or from youtube
"youst for fans , a smart diablo runs in a super tunned hayabusa susuki powerfull 1200hp + 60 hp of the tunned aregement , and makes not two 60mph or 100kmh in 3 sec , thats faster than the bike becouse if you are under the 80 kg you and the car weight less than 600 klg so is litter than the bike and a 1260 hp tunned engen moves that really faster"
I think it's something to do with power to weight ratios - is that what this means?
