As icing on the cake, the hybrid models will reportedly be equipped with a special version of the 6.0-liter V-8 engine, larger than the standard Tahoe's 5.3. Add the larger displacement to the added boost of the hybrid motor, and you've potentially got a pretty quick ride.
So, are there any downsides to the new big hybrids? Sure, a few. You take a 2,000-pound hit in towing capacity, and an estimated $10,000 premium for the hybrid hardware. Initial production estimates are a conservative 10,000 units, but could potentially go much higher.
Our Take: It seems Americans have an insatiable appetite for big things. If you can get as good or better economy than the new unibody crossovers, and still have your big, beefy body-on-frame chassis and V-8 power, some may be willing to pay a premium. Would you?
