The DRIVe engine changed over to the 8 valve unit when the D2 it is based on came out in late 2010. MY11 & 12 DRIVe cars with 6 gears use the 8 valve engine.
Also I have to be honest, I have had better MPG from my 16 valve units than I get from my current 8 valver but one of them was re mapped and it went really well and got great MPG. You can't remap the 8 valve for as much power and they are slightly strangled in terms of power delivery out of the box and there's not an awful lot you can do to improve MPG and power on an 8 valve. Then again, I'm not the best person to talk to about fuel economy, my other car is a 400 bhp AMG Mercedes V8 so everything else I drive is woefully underpowered in comparison!! I get just about 50 MPG out of mine but I bought it for the spec and the free rfl
