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.

Junkyard Gem: 1962 Buick Electra 225 4-Door Sedan

Buick built its first Electras as 1959 models, with Electra production continuing unabated through 1990 (after which the Park Avenue trim level took over as the model name, much as the Malibu trim level designation had shoved aside the Chevelle model name in 1978). Some of the handsomest Electras were the second-generation models, built for the 1961-1964 model years, and today's Junkyard Gem is one of those cars. I'd always assumed that the Buick Electra took its name from the daughter of Clytemnestra and Agamemnon in Greek mythology, because the people who named cars back then were forced to read Euripides and Sophocles as undergrads. In fact, the car was named after Electra Waggoner Bowman Biggs, a Texas heiress and sculptor who married the brother-in-law of Harlow Curtice, who ran the Buick Division before being promoted to president of General Motors in 1953. How did she feel when the last Electra rolled off the assembly line in 1990? The junkyard is full of history, if you know where to look. The 1959-1960 Electra had enormous tailfins, angled something like the ones seen on the same-year Chevrolet Impalas. This Electra generation ditched the fins but kept much of the general Space Age spirit of its predecessor. The Electra lived on the same platform as the Cadillac DeVille and Oldsmobile 98 from start to finish, and it was the most expensive Buick available in 1962. The MSRP of this one was $4,051, or about $41,462 in 2023 dollars. The engine in this one was present when it arrived at U-Pull-&-Pay, but a junkyard shopper grabbed it within a couple of days of arrival. It would have been a 401-cubic-inch (6.5-liter) "Nailhead" V8, rated at 325 horsepower and a whopping 445 pound-feet of torque (keep in mind that these are gross, not net, power numbers). The Nailhead's small valves meant that it wasn't much good for high-rpm use, but its big torque was perfect for moving two-ton land yachts. The final Nailheads were installed in 1966 Buicks. Every production Electra ever built came with an automatic transmission, and the 1959-1963 models received the extremely smooth and alarmingly inefficient Dynaflow (known as the Dual-Path Turbine Drive for 1962). Originally developed for use in the 1943 M18 Hellcat tank destroyer, the Dynaflow was considered a two-speed automatic but drove more like a CVT with two selectable drive ranges.

Buick Envision CUV displays full-frontal nudity

Earlier this month, Shanghai GM gave us a glimpse of the production version of the Buick Envision concept revealed at the Shanghai Motor Show back in 2011. And now it's released the first unveiled shot and initial details of the crossover to slot in the considerable gap between the Encore and Enclave.
The new Envision is set later this year to reach Chinese showrooms, where it will be called the Ang Ke Wei, after which we're expecting it to arrive Stateside. The production-ready Envision is about the size of the Chevrolet Equinox or GMC Terrain, but is differentiated by a more upscale treatment and Buick's signature waterfall grille, flanked by Xenon headlamps and LED running lights and riding on 19-inch wheels.
Power comes from GM's familiar 2.0-liter turbo four with direct injection and stop/start ignition, driving 256 horsepower and 260 pound-feet of torque through a six-speed automatic transmission to all four wheels. That's about all that GM's Chinese operation has announced at this point - it's not even clear what platform the vehicle is on - but you can check out the press release for yourself below.
