What we really want to know is how much power it makes.
Plenty of speculation has currently caught up the new Buick Regal in a swirl of rumors, some of which are promising in the sense that they indicate the automaker is moving towards a future of fun to drive vehicles with plenty of power and in some cases, borderline good looks (although that's subjective). A previous rumor indicated that the next generation Regal GS would get a 3.6-liter V6 from elsewhere in GM's lineup, and now The Truth About Cars has found more compelling information.
Keeping enthusiasts interested in Buick to an extent (though don't expect a Grand National GSX anytime soon) was the distant possibility that the new Regal GS would have horsepower outputs comparable to the V6 Chevrolet Camaro, albeit with all-wheel drive available to help get the car off the line more quickly. Thanks to a California Air Resources Board document found by TTAC, we now know that the Regal GS will have a 3.6-liter V6 engine, though the power output remains to be seen. Similar engines of the type make between 305 and 335 horsepower, but as noted by Jalopnik, another practical power plant could be the 288 horsepower LLT V6 from taken from the Buick Enclave.
TTAC seems to think there's a distant possibility that the Regal GS gets even more horsepower, but we would be a slight bit surprised to see that happen as China, one of Buick's main markets, will not even get the option of a V6, sticking only to the 2.0-liter turbocharged engine that makes 250 horsepower. The CARB document also states that the engine will be mated to a nine-speed automatic gearbox with no manual available this time around. As suspected, power will be sent out to all four wheels via Buick's special AWD system that works to send torque where it's most appropriate. Expect to hear more about this odd TourX and Sportback duo in the coming months as it starts to roll out.
