I thought I'd try to find performance curves for the engine Mercedes use in the AMG A35, this is a 2.0L twin scroll turbo, normal power output is 306 bhp, peak torque is 400mn at 3000 rpm.

The red lines are as standard, the blue a "Stage 1" re-map offered by an after market supplier. Tempting...

BUT the key point I wanted to make is that the torque curve shows a much more "traditional" shape, unlike the almost vertical one of the BMW. This makes the car easier to manage and the 4WD makes all the power more usable.

Take a look....
