The BMW 135i is a small car that's rear wheel drive with a 3.5 liter twin turbo inline 6. It throws down a lot of hp for a car of its size, and it's 0-60 is about 4.8 from what I show online.The Civic Si is front wheel drive and has a 2.0 liter inline 4 with vtech. It gets from 0-60 in 6.8 seconds, a full two seconds behind. I'm sure that there are plenty of turbo kits and whatnot for it, though, that would get it up into the same range as the 135i for acceleration. Don't know about handling, though... the 135i has a MUCH sportier chassis.I'm not sure about the top speeds. I can guarantee both are electronically limited.
