However, I'm a bit dissapointed with 27.1mpg, it has improved very slightly since picking the car up (26mpg) and we have done just over 2000miles. I was hoping for more but I guess I'm kidding myself.

Does anybody know if the DMS chip would improve mpg as well as performance?
Clutching at straws here to try and justify the power gains

My main gripe is with BMW for announcing the efficiency dynamics pack (and the lower tax group) just months into the new model being released. Shocked to see that even the sd benefits from the lower tax band. I can't help but question whether these cars will pass their MOT emisions test in 3 years time though...

Lexus put a £5000 premium on the RX400 hybrid, what is BMW going to charge extra for their attempt at the Synergy drive?

DMS chip is supposed to give better consumption and power. They get very good reviews
