Buick dusting off Grand National, GNX and T-Type nameplates

Inside Line reports Buick is planning to bring back some of the more storied names from the company's past, including the Grand National, GNX and the T-Type. Those cars rose to prominence in the 1970s and '80s to become performance legends of their day.
The new models will reportedly make use of the rear-wheel drive platform that currently underpins the Cadillac ATS and all would arrive as sedans - according to an unnamed source familiar with the initiative. Odds are the T-Type and the Grand National would share a driveline, with honest money being on a new twin-turbocharged 3.6-liter V6 as the engine of choice. Word has it the mill will be good for anywhere from 350 to 400 horsepower.
That leaves only the GNX. Inside Line seems to think that machine could get down the road with some help from the all-new GM LT1 small-block V8. The engineers behind the ATS platform have already told us the engine bay is large enough for to accommodate the big eight pot, and since GM is most certainly working on an ATS-V, a slightly less powerful, less luxurious Buick iteration makes some kind of sense. We can't wait to see these things in the light of day.

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

Buick rolls out more potent Encore Sport Touring

Buick has announced a new Sport Touring version of the Encore. And more than a trim level or special edition, we're glad to report that the new model packs a more potent engine. Instead of the 1.4-liter turbo four that produces 138 horsepower and 148 pound-feet of torque in the standard Encore, the new Sport Touring model features a newer, more powerful engine that GM says shares little with the existing unit aside from its displacement. The new 1.4-liter turbocharged, direct-injection engine produces a more commanding 153 hp and 177 lb-ft of torque, which is up a good 11 percent and 20 percent, respectively, over the existing engine. It's still mated to a six-speed automatic transmission, and features a stop/start system to optimize fuel efficiency. Buick wasn't willing to estimate where the mile-per-gallon numbers might land, though that information will be available closer to sale. Along with the upgraded engine, Buick is also throwing in 18-inch wheels, a rear spoiler, and the features from the Convenience package as well. The new Encore model follows just a couple of months after we first caught wind of a trademark filed for the Sport Touring name. At the time, it looked like it was set to be applied to the Regal and LaCrosse sedan, which could still follow as well.

It is distinguished by unique exterior cues and driven by an exclusive, all-new 1.4L turbocharged engine featuring direct injection and stop/start technology. The exterior features include a winged rear spoiler, 18-inch aluminum premium-finish wheels and body-color door handles, while the technologically advanced 1.4L turbo is part of a new, global family of small, power-dense engines developed to balance performance and efficiency with exceptional refinement. Direct injection helps it generate an estimated 153 hp (112 kW) and 177 lb-ft of torque (240 Nm), for about 11 percent more horsepower and nearly 20 percent more torque than the Encore's standard engine – and a greater feeling of power on demand, particularly at low- and mid-range engine speeds. It's matched with a six-speed automatic transmission. Stop/start technology contributes to reduced fuel consumption in stop-and-go driving.
