The base model is of course powered by GM's excellent 3.6L V6, though the direct inject version that's available with the Cadillac CTS. Expect around 260 HP for the V6, and it's mated to a five-speed automatic. The G8 GT, meanwhile, gets the General's 6.0L V8 paired with a six-speed automatic. Sorry, there's no rowing your own boat in a Pontiac G8, as no manual transmission appears to be offered.
We're pretty impressed that GM managed to keep the base price below $28,000, and that there's only $2,400 separating the two models. Mark our words, this car will sell out, at least in its first year of production and perhaps one or two after that.
