MB sixes are alright in terms of power output. 218 horsepower is decent for a 3.2 liter SOHC V-6. However, Audi's 220 hp 3.0 liter and BMW's 225 hp 3.0 liter and Acura's 260 hp 3.2 liter all better it.....

Now the V-8 situation is somewhat sorrier.

The Infiniti Q45: 4.5 liters. 330 hp.

Lexus LS430: 4.3 liters. 300 hp.

BMW 745i: 4.5 liters. 330 hp

Mercedes S500: 5.0 liters. 302 hp

BMW M5: 5.0 liters. 394 horsepower (possible from an NA 5.0 liter)

BMW X5 4.6 iS. 4.6 liters. 350 hp.

Ford Mustang Cobra (I know, I know) 4.6 liters. 320 hp.

Has MB lost its way with the larger engines?
