Straightline

Gah! So much for that GL420 CDI I'd been hoping for. Oh well. I think it's kind of a non-sense claim anyways. Who really Needs any more that a turbo four in Anything? Think about it, V8's of a decade ago were barely making 250 hp, and now we've got a 260 hp turbo four, and the torque isn't that far behind. That'd actually be really fun to see-just how liveable is GM's 2.0 Turbo/ 6-speed automatic in something like a Tahoe or Suburban? I'd bet people would be surprised at how easily daily life progressed. And with Hybrid-beating fuel mileage to boot! The point is, people don't Need more power, they WANT more power. Especially in the luxury car arena. I see Audi coming out ahead on this bone-headed move.

Performance hybrids have mostly failed here, you have to wonder if it makes sense to market performance diesels.
 
I say go for economy. They can meet that goal and still have more than adequate performance with a turbo diesel 6.
