hey aem u.s 325i has 215hp and 3000cc, next time get ur facts right
215 horsepower and 229 lb of torque -> 03 clk 320
215 horsepower and 185 lb of torque -> 06 325i
but remember the clk is heavier, 3515 lbs vs 3351lbs and clk is 5speed while bmw is a 6speed..
again, i'm confident that 325i would win against a clk320
