Comparing the Camry gas to the GM hybrid is a little unfair since the Tacoma would be a better, in-class vehicle. However, this does let us look at the gas-vs-hybrid for the same models and 150% versus 157% is pretty good. I'm looking forward to test driving the GM hybrid.

Do the Tahoe/Yukon models still use an engine driven, AC compressor? What accessories are still engine driven in the hybrid Tahoe/Yukon models?

Engine driven accessories including the coolant pump are 'low hanging fruit' that can further improve mileage.

Thanks,

I think the point of comparing the Tahoe / Yukon Hybrid to the Camry is basically to point out that the consumer does not have to move from an SUV to a sedan to get decent fuel economy. Placing a V8 Tahoe Hybrid and a 4 cyl Camry side-by-side, it is hard to rationalize that they get similar gas mileage.

If the idea is to compare "like vehicle" the Tacoma comparison is not really apples - to apples either. Pickups and SUVs don't tend to overlap until you get to full size crew cab pickups. SUVs do tend to interact across size and value lines (mid-sized v large, large v luxury, etc). Better comparisons would be....

Highlander V6 (18/24)
Highlander Hybrid (28/25)
4Runner V6 (16/21)
FJ V6 (16/20)
Pathfinder V6 (15/22)
Pilot V6 (16/22)
FX35 (15/22)

Don't know EVERYTHING that's engine driven, but for the hybrid, the AC compressor is not and is capable of operating with engine off.

Peace,
