Buick working on Encore refresh

It's been three years now since the model we know as the Buick Encore (sold overseas as the Vauxhall/Opel Mokka) first hit the scene. That makes it about due for a bit of a facelift, and judging from these latest spy shots, that's precisely what General Motors seems to be up to. The nose of this prototype (intriguingly wearing Buick badges but German plates) is all covered up, so it's hard to tell what Buick and its European counterparts have in store for the front-end restyling, but the fact that they've covered it so extensively tells us that somethings afoot. The tail should also get new lights and bumper as well. You can fully expect GM to take the opportunity to refresh the cabin while it's at it with tweaked ergonomics and new equipment. Meanwhile our sources tell us the 1.0-liter inline-three from the new Corsa could find its way under the Opel/Vauxhall's hood to join the current lineup of four-pots, but it's too early to say whether that engine might find its way across the pond to the Buick version as well.

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.

1987 Buick Regal GNX driven just 54.8 miles heads to auction

The previously unimaginable prices for seemingly anything on any number of wheels continues to lure garage queens into the open. Here we have another Buick GNX headed to auction, this one Mecum's Summer Special in Orlando from July 6-9. Buick only made 547; it feels like half went to owners who never drove them. The last GNX auction we covered, in 2019 on Bring a Trailer, ended up grossing $200,000 for a model with 8.5 miles. This example has been driven much harder than that, praise be to enthusiasts, with 54.8 miles on the odometer. That means the original owner, who kept the coupe until 2017, got more than six times the use out of his GNX than the 2019 owner. Way to go. For those who haven't attended any classes on the Buick Regal GNX, allow us to summarize the subject matter. When Buick greenlit "a Grand National to end all Grand Nationals," out came the one-year-only 1987 GNX. A racier brand back then, it partnered with ASC/McLaren to work up the wheel lip flares, fender vents, 16-by-8-inch BBS rims, more aggressive tires, and the interior treatment. The Grand National trim used a 3.8-liter V6 making 245 horsepower and 355 pound-feet of torque hooked to a four-speed automatic. The GNX benefited from a larger Garrett T-3 turbocharger with a ceramic impeller, a larger intercooler, more aggressive fuel, spark, and waste gate tables, and a dual exhaust system that boosted output to what some say is an underrated 276 hp and 360 lb-ft.  This GNX headed to auction spices up the standard specs with the original order paperwork, window sticker, dealer invoice, ASC documentation, a GNX coffee table book, and a GNX jacket. That jacket could be the denim one or the high school varsity jacket with the cloth front and back and leather(ish) sleeves, which, sadly, didn't include Buick's attacking eagle logo of the time. We'd mention the black and sand gray cloth interior, power driver's seat and mirrors, and Delco Concert Sound stereo, but it's likely that the future owner won't spend much time with them. Likely fated to be a garage or show queen again, the jet black paint, "original parts stickers still affixed on suspension," and "original chalk markings throughout" will be the major points of interest. Mecum doesn't give a pre-sale estimate for this GNX, so we'll be waiting to find out if the 2019 sale price was an anomaly — well, more of an anomaly — or the new benchmark.
