0-100kmph in 4.2 secs is supercar figures? No supercar of this day takes more than 4 secs to reach 100. Most supercars have 3 point something timing. Saleen does it in 2.7 secs., Keonigseggs are below 3 secs, let's not discuss the Veyron.
Even a Porsche 911 Turbo (not a supercar; just a superfast sports car) makes it in 3.7 secs (manual shift) 3.4 secs (tiptronic).
Dudes, even a Lotus Exige that costs just $55K, reaches 100kmph in 4.1 secs. So supercars are definitely a different league but 4.2 secs is not in that elite supercar league.
