Interesting. As usual Mercedes won't just jump into direct injection for gasoline engines unless they find a way to make it unique. I wonder if he is talking about the direct-injection version of the new 3.5L V6 that was shown in the hybrid at Frankfurt? That engine produces 292hp before the electrics are added. A 292hp E350, SLK350 etc. etc. sounds good to me.

Mitsubishi promoted their GDI (Gasoline Direct Injections) engines like crazy in Europe stressing improved performance, better fuel economy and other benefits. Unfortunately, it seemed the Mitsubishi GDI engines were only "fuel efficient" if one drove like snail and power? What power? I suppose some carmakers kept that story in mind and won't touch direct-injection until they find more benefits to it. Besides, the average Mercedes gasoline engine offers relatively decent power-to-fuel-economy ratio in my experience.
