GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

It looks like Buick is working on a new Regal GS

When Buick revealed its Regal-badged version of the Opel Insignia/Holden Commodore sedan and wagon, it left out one significant model, the GS. The high-performance Regal was missing in action, but these new spy photos seem to indicate one is coming soon. It looks like it will be pretty subtle on the outside. Upon close examination, we can see that each side of the front bumper features a much larger grille than the normal Regal Sportback and TourX. The thick upper borders on the grilles also look like good places for some LED accent or fog lights. These larger grilles appear to be the only significant difference to the front, though. On the sides, there are slightly deeper side skirts than those on a standard Sportback, and the rear bumper looks to be lifted from the TourX, but without the wagon's aluminum cladding. One other indication that this is a high-performance Regal is the car's front braking equipment. We can make out a Cadillac logo on the front brake calipers, which shows that this isn't running standard Regal stoppers. As for what's under the hood, it's tough to say, but we don't think it will use a turbocharged four-cylinder as the previous generation did. Instead, we think it may be using a V6. That's a hard maybe. The base Regal's turbo four makes as much power as the old GS, and although Buick could crank up the boost for more power, it could also make use of the V6 it will offer overseas. In the mechanically identical Commodore, a 308-horsepower V6 will be available along with a 9-speed automatic and the same type of all-wheel-drive system as the Ford Focus RS. This option would make the upcoming GS more powerful than the old one, and the new standard model, plus offer all-wheel drive. We would like to see even more power than 308, since the top-dog previous-generation Insignia OPC had a 325-horsepower V6.

Last-ever Buick Grand National heads to Barrett-Jackson auction

This 1987 Buick Grand National brought the curtains down on a heap of General Motors history. When this black beauty rolled down the line at 5 p.m. on December 11, 1987, it represented the end of manufacturing at GM's Pontiac Assembly Plant after 60 years building cars. This was the last car to sit on GM's G-Body platform, having supported legendary names like Monte Carlo, Cutlass Supreme, and Regal. And this was the last-ever Buick Grand National, a big coupe that in just five years on the market had helped make the Buick Regal lineup an object of sincere lust among enthusiasts. Powered by a 3.8-liter turbocharged and intercooled 3.8-liter V6, the engine made 245 horsepower and 355 pound-feet of torque. The only car above it in the lineup was the exceptionally rare GNX, which made 276 hp and 360 lb-ft. The Buick Grand National is headed to the Barrett-Jackson auction block in Scottsdale next month.    Louisiana resident Bob Colvin bought this car from the factory. The Drive spoke to Colvin, who explained that then-GM President Roger Smith told him he could have the penultimate Grand National, but Buick planned to put the last car on display. When Colvin arrived at the plant, though, Colvin said the plant manager told him, "I'm running this plant and you've gone through the effort to be here. It will be a real celebration," and got him the last car made. As proof, a GM film crew followed the car down the line, plant workers and two GM execs signed various parts of the engine, including current GM President Mark Reuss. The car comes with all of the autographs and signage the autoworkers created to go with the car, as well as the original window sticker. Colvin and his wife built an addition onto their house to display the car. Save for a trip to the Buick Centennial Celebration in 2003, the Buick has lived in its special place all its life and has just 33 miles on the odometer. Behind the new-car plastic that shrouds the interior, the only flaw appears to be a tiny crack in the steering wheel center cap where a bolt might have been overtorqued. The car is being offered with no reserve, the pre-sale estimate landing right around the $500,000 mark. That would about double recent auction sales for low-mileage GNX's this year, but there's every reason to believe this car's one-of-one place in history could get auction paddles waving.
