^^ It is. But if Caddys came in a 300 hp 4 cylinder vs a 300 hp V8, I wouldn't be as happy. A V8 brings with it a certain sterotype regarding money.
"A big car needs a big engine" is what I have heard many, many times. Not necessarly in regards to horse power, but size (cylinders and liters). And we must remember most people measure a car by the number of cylinders it has, hp & torque figures are second seat.
Plus, the power delivery that comes from an engine with more cylinders is more even and smooth, thus, associated with luxury.
The M3 is definitely sport first luxury a far second. The Cad500 puts out smooth, even power. The northstar puts out less smooth, even power, since it's aimed for a higher RPM range. An M3 I6 puts out nothing on the bottom end and everything on top.
This is all a moot point. Once Lincoln get's the super sedan built, it will all be for naught. The CTS-V, SRT-8's, M5's, E63's, S6's will all be at or near 500hp. A 400hp Lincoln will not be competitive and priced anywhere north of $40K will not sell. Price below $40K and they can't make money. Too little, too late.
No, it doesn't. CTS-Vs have regularly gotten low to mid 4's in the 0-60 sprint. I don't think I've ever seen any IS350 in the 4's. So no, the same cannot be said for the Lexus.
