I believe the X1 can cover the 1/4 mile in a lot less than 9 seconds. My drag car reaches 60mph in oughly 2 and a half seconds and covers the 1/4 mile in just over 9 seconds. Something this light that can reach 60 in 1.3 seconds is going to probably reach 400m / or 1/4 mile in well under 9 seconds. Probably more like low 8's possibly high 7's with the right suspension and tires.
It's not a drag car,but being as light as it is with over 1,500hp and vast amounts of downforce it's going to be fast no matter what.I mean we see 1,500hp drag cars that weigh close to 2,800lbs that are running 7's. Mind you these are purpose-built drag cars. But still, the X1's formula for speed is hard to argue with. Light-weight, crazy downforce, and 1,550hp.
