GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.

Two nearly new 1987 Buick Grand National 'twins' found in garage after 30 years

Back in the '80s, a Buick Grand National could leave a lot of vehicles in its dust. The final, 1987 version of the menacingly styled performance coupe produced 245 horsepower and 355 pound feet of torque, and it was never designed to sit still, let alone for 30 years. But two low-mile Grand Nationals did just that. At the time, it was widely known that nothing like the Grand National would be built again, as the Regal platform would be moving to front-wheel drive. So a lot of buyers stockpiled Grand Nationals and rarer GNX versions with the idea of making a buck on them when they gained value. Some people even bought several. That's what happened to these two cars, recently unearthed from their slumber. Thirty years of storage has turned them into barn finds instead of showroom beauties, and they haven't exactly been flawlessly preserved. A story reported on gm-efi.com shows the cars – the "Twins," as they're called – parked side to side, the way they were laid to rest decades ago, with thick dust on them. Two enthusiasts, Shawn Matthews and William Avila, originally contacted the owner, who had posted them for sale on Facebook with a staggering $200,000 asking price. After inspecting the cars and confirming they were legit, the prospective buyers managed to strike a deal for an undisclosed sum. The story does say the seller was a bit eccentric, demanding money in hand before the cars could be touched at all, but the cars were eventually acquired and transported to a shop for desperately needed refurbishing. Time has caused the headliners on both cars to droop, and it's obvious all gaskets and fluids will need to be addressed, but both cars have extremely low odometer readings: One has 807 miles on the clock, while the other hasn't even reached 600. The car with a more miles was moved "once in a while," so clearly the original owner couldn't resist giving it a go while the other one slept. We couldn't've, either.

Cadillac, Buick and Chevy decisions impacted by worries abroad

European Concerns Drive GM, But Beware Of The French Connection
GM's bid to rationalize Europe will impact the products that will be offered domestically.
It seems that Europe is defining the future of General Motors more so than its home North American market. Having axed Saturn, Pontiac and Hummer, GM has done a fairly good job of repositioning its remaining four divisions, Cadillac, Chevrolet, Buick and GMC. Cadillac carries the luxury banner. Chevrolet is aimed at the masses with cars and trucks along with a nod to performance thanks to Camaro and Corvette. Buick bridges the premium gap between Chevy and Cadillac, while GMC offers a hardcore work/upscale proposition.
