Lo and behold, the road and track summary for the IS 350 -
0 to 60 MPH in 4.9 seconds
1/4 mile in 13.5 seconds
At the risk of sounding semi tacky, I'd like to make it known that the IS 350 is as fast in a straight line as a 1999 aston martin db7 vantage. But, oddly enough, if you were to just throw those two names out there and asked people to respond (within one second) which is faster, '99 aston martin db7 vantage or IS 350, I think most people would almost immediately say "aston martin."
Even down low (and I think most people can attest to this given how strong the low end acceleration is IF you get good traction and that ninny traction control is not interfering), the IS 350 is, what, tenths of a second slower than an '03 lamborghini gallardo -
Gallardo: .................... IS 350:
0 - 10 MPH: 0.6 s ........ 0 - 10 MPH: 0.5 s
0 - 20 MPH: 1.1 s ........ 0 - 20 MPH: 1.0 s
0 - 30 MPH: 1.8 s ........ 0 - 30 MPH: 1.9 s
0 - 40 MPH: 2.5 s ........ 0 - 40 MPH: 2.7 s
0 - 50 MPH: 3.4 s ........ 0 - 50 MPH: 3.8 s
Hell, the first gear (0 to ~36 MPH) is actually just as strong as that of a gallardo.
You're getting to 50 ".4 seconds" slower than a $200,000+ gallardo? I'll take it. Although, to be fair, .4 seconds is actually..a lot, but there are very few sports luxury sedans/coupes that can match that. bmw 335i and 135i are two that certainly can. '08 g35 6mt is close (why am i not mentioning the g37? because sadly it's sadly SLOWER than the '08 g35s. go figure). 370z can, and the '07+ HR 350zs are capable as well, but when we go into 350z/370z territory we're moving away from the "luxury sedan" segment. I mean, of course they should be able to produce those kinds of numbers, that's what they are made
for in the first place, while the IS 350 is made for being a luxury sedan.
IS 350 is no slouch for sure. And the best part about it? The purpose of the IS 350 is to act as a luxury sedan first and foremost. The powerful acceleration is merely an added bonus. In terms of "bang for your buck" the IS 350 is very very hard to beat. It's a luxury sedan..that gets to 60 MPH in under 5...all for ~$20,000-$25,000 used. If you want pure speed/acceleration, then obviously there are a slew of better cars out there, BUT there are very very few cars that have the combination of powerful acceleration..AND luxury..AND reliability..AND "bargain pricing" that the IS 350 has. It's a very low maintenance luxury sports car.
But you know, I don't really blame you for wanting the IS 350 after driving it. I say go for it.
