I wouldn't let one review cause such an outrage. Although, in Mercs defense, they really have stepped up their AMG cars. Coming from someone whose family owns a Merc and Audi dealership (let's not talk about why I drive a bmw
) The new AMG's are much more responsive than the older ones. And the exhaust note is just something to be heard. I haven't driven the brand new twin turbo e63, but I have driven the new cls63 and it is an amazing ride. Plus, don't forget that Benz offers the high output package which gives it more HP from an increase in the psi for the turbos (550 hp, 590 torque). I do think its a bit of a shocker though that this new m5 weighs more, you'd think that it'd be lighter, and it has a smaller motor than the benz. Gotta see what other reviews say!
