2018 Buick Enclave: How engineers made it larger, lighter, more sophisticated

Buick used the unveiling of the 2018 Enclave at the New York Auto Show to introduce its new range-topping Avenir sub-brand to the world. With fancier interior finishes and exterior details, it's Buick's latest effort to make itself a proper luxury brand (or perhaps re-establish itself as such). However, lost in the Avenir song and dance is the fact that the 2018 Buick Enclave is a (very) long-awaited all-new model regardless of the trim level one selects. Like the Chevrolet Traverse upon which it is based, the new Enclave is bigger than the vehicle it replaces but considerably lighter, by about 400 pounds. "We told every engineer, 'get your job done, but then take the weight out,'" said engineer Rick Spina as we hovered next to his larger yet lighter creation. His team therefore set about taking a little bit of weight out from just about everywhere, from using additional aluminum in the suspension to varying the thickness of the frame (thicker in places that needed to be stronger, thinner and therefore lighter in places that didn't). Only about 100 pounds came out of the body with the rest coming from elsewhere. Not only will the reduced weight improve fuel economy (Buick-estimated at 19 mpg combined with FWD versus 18 for the 2017 model) and presumably the old Enclave's rather ponderous handling, but it should only make things easier for the new powertrain: General Motors' now-familiar 3.6-liter V6 and its latest nine-speed automatic. With 302 horsepower and 260 pound-feet of torque, Buick says the new engine will need 7.2 seconds to reach 60 mph with FWD or 7.5 seconds with AWD. That's a second quicker than before. Besides acceleration, towing is also bumped up by 500 pounds to 5,000. For those models with all-wheel drive, the Enclave has the same basic system featured on range-topping versions of the Buick LaCrosse. Besides power being sent front and rear, it can also differ from right to left in the back, although Spina is quick to point out that capability is for traction-enhancing purposes rather than sporty, handling-enhancing torque-vectoring ones. Buick owners already appreciated the Enclave for its quietness so the engineers decided to take it that much further. This included altering the exhaust, improving body sealing (there are triple door seals), including active sound deadening and utilizing advanced materials that absorb sound as opposed to simply being thick, dense and heavy enough to keep it out.

2022 Buick Encore starts at $25,795

The Buick Encore entered the market here for the 2013 model year, its combination of solid, practical, and premium-ish content working well enough to increase sales by about 10% every year until 2019. The shine on that first-year model was such that it was recently voted one of the best used-car buys under $10,000. Still in its first generation, the Encore soldiers into the 2022 model year with a few small changes. The biggest update for the 2022 Encore is a newer 1.4-liter four-cylinder engine with more power. The previous unit produced 138 horsepower and 148 pound-feet of torque; the new 1.4 will unleash 155 hp and 177 lb-ft. That engine will only be available on the Preferred trim — which is the only one left. In 2018, the Encore came in six flavors. Whittling reduced that to a base model and a Preferred model for 2021, and for next year the base departs. Also (kind of) under the hood, an electric heater and defroster replace the traditional heater core system, for faster toasties in cold climes.  The only change outside is the addition of an exterior temperature sensor. Inside, the eight-inch infotainment touchscreen shrinks to become a seven-inch touchscreen. The passenger's seatback will no longer fold flat, so Buick took the opportunity to add a seatback map pocket to the shotgun position. Buick will charge $25,795 for the 2022 Encore, that figure including the $1,195 destination charge. It's the same price as the 2021 Encore Preferred.  The continued paring of the lineup suggests GM is ready to wind the model down now that the tiny-bit-larger and more profitable Encore GX is killing the Encore in the sales race. Through the end of September, the Encore is down on its 2020 sales volume in the U.S. by about half, whereas the Encore GX has more than doubled its 2020 sales so far this year. Automotive News reported that the Encore will quit the U.S. market in 2023 without a replacement as the automaker digs into its electric efforts. GM Authority believes there's a chance the new-generation Encore sold in China could come here. 

2014 Buick Regal GS

A few months ago I drove the 2014 Buick LaCrosse and wrote up a First Drive review of it. For all of my quibbles with that sedan (and I had a fair number), I understand that it speaks to the heart of what new Buick loyalists like in a car; it's roomy, has a cushy ride and is as placid as a summer's morning at highway speeds.
Those qualities, while undeniably desirable, don't mean a whole lot to me personally. I prefer sedans that conjure up words like "nimble," "punchy" or even "raucous" on occasion. So, directionally, the high-performance GS version of the 2014 Buick Regal is more my cup of tea than any other car in the company's current range.
In fact, I'd already come to know the Regal GS from its 2012 model year introduction, and grown more than a little fond of the sporting sedan in its original front-wheel-drive, six-speed-manual guise. The fast, sweet-handling car with well-sorted controls may have suffered from a slight identity crisis in terms of pricing (and may still), but it was undeniably fun to drive. So, when I heard that the GS was coming to market for 2014 with optional all-wheel drive (albeit only in combination with a six-speed automatic transmission), I was stoked to have another go and concentrated my driving impressions on the AWD car.
