3.6 vs 3.6
A bit confusing.
What is the difference between the two V6's
Gas mileage, power, and RELIABLITY-
One is Direct injection, one has variablle valve timming.
Any other great differences???
I'm still looking at 09's and asking price seems to vary a little between the two engines.

Re: 3.6 vs 3.6
VVT- 263 HP @ 6200 rpm
DI- 304 HP @ 6400
VVT- 253 lb-ft torque @ 3100 rpm
DI- 273 lb-ft torque @ 5200 rpm
I don't have exact EPA numers, but the DI engine was rated the same as the VVT engine IIRC. That was a big selling point for the DI engine as it was more powerful and just as efficient. And the DI engine is supposed to be better from an emissions standpoint. As for reliability, I don't think there is much difference between the two. The 3.6 VVT has been around since the 2004 CTS and SRX and the DI version arrived with the '08 CTS. I haven't driven a non DI model, but based on the torque numbers, I imagine it has more punch down low while the DI motor loves to rev.
