Mainly motorways 4 up at a steady 70-80. Good job I don't run it all year round.

Think the turbos may actually help the mpg as there is loads of torque so you don't need much throttle input. Trouble is the m3 used to do 30+ and the cavalier turbo nearly 40.

Should be 30 plus I'd of thought matt. Think mine would do 30 if it were 2wd.

Mine also does about 25 mpg, 320 bhp MSD with closed loop and wasted spark. I wonder what it would do when it was just 2wd.
