i doubt the new engine would have crazy torque levels and rev range to benefit from a DSG box

stop/starts are fail imo, if youre THAT concious about fuel economy, buy a charade...would be sooo annoying in peak hour traffic jams i reckon

the performance figures arent that significant either concidering the car is 200kgs heavier than a cl9...if they want better fuel economy why not just lighten the car?
