6.8 0-100kph on a sorento.:bwahaha: sorry but unless it's heavily modified it would be impossible.
anyway tons of cars these days can reach 0-100kph in 10seconds or less the better question is their trap speed. i've seen cars that can reach 0-100kph in 8-10 seconds but then needs another 8-10seconds just to add 30-50 more kph. for me anything that can reach 0-100kph is good enough for my needs. if we're talking about sports cars then that's a totally different story then.
