Unfortunately there's two faster production sedans in similar range. The new Porsche Panamera and the UK-specific model of the Evo, the Evolution X FQ-400. Neither of them will compete, but:For me I think i would have to go with the Cadillac CTS-V. Yes it is a Cadillac but i mean come on its a 4 door, 556hp, 3.9sec 0-60 supercharged monster. The great thing about this car is its quality parts Brembo Brakes, Recaro interior, Tremec Tranny. This car is not only built for speed but longevity. It has great styling ques and hard lines that really look great. Not to mention that it is the fastest 4-door to ever grace the nurburgring. There are some other quality cars in this same class like the V10 M5, but for me the CTS-V just does it!!!
