Buick Avenir concept struts into Motown

We love auto show surprises, and Buick has already gifted us a sparkly package on the eve of the 2015 Detroit Auto Show. Dubbed Avenir, this four-door concept is said to signal the future of the Trishield brand by previewing a possible flagship sedan. Incorporating time-honored Buick design hallmarks like the sweep-spear profile, Ventiports, and even a subtle boattail rear-end, the four-place sedan is powered by a surprisingly real-world powertrain – namely a next-generation V6 with cylinder deactivation and stop/start, with the most interesting part of the driveline arguably being a "twin-clutch all-wheel-drive system" and a nine-speed automatic gearbox with paddle shifters. Make no mistake, this is a big car. At 204.5 inches long, it's longer than a standard-wheelbase Cadillac Escalade – a span that's emphasized by the car's long hood and waterfall grille – though it's not quite as wide. While clearly a showcar, the beautifully crafted interior looks largely produceable, including attributes like a next-generation 12-inch touchscreen infotainment system and 4G LTE wifi, but we suspect a production car would pick up a third rear seatbelt and give away some of its flowing contours that are said to have been "inspired by nature and sea waves receding on a beach." No word yet on whether there's actually a showroom future for a car like this – it could simply be an exercise designed to test the waters for a next-generation LaCrosse. After all, sedans aren't exactly popular concept fodder these days, especially as crossovers continue to eat into traditional sedan sales in many of the world's markets. However, China still loves the coddling rear seats of a proper four-door sedan (which in this case include silk and bamboo elements), and with a majority of Buick sales happening in the People's Republic, the Asian nation controls the destiny of this General Motors brand. Said another way? Anything is possible, especially with General Motors known to be working on a large flagship sedan for Cadillac already – the Avenir is reportedly based on the same Omega architecture that will underpin the forthcoming CT6. What do you think? Is this a promising direction for the resurgent Buick? Scroll through our gallery, check out the video, and then have your say in Comments.

1969 Buick Riviera is latest Hot Wheels Legends finalist

The Hot Wheels Legends Tour traveled to Southern California, one of the bastions of car culture in the United States, to find the next custom-built car that it will add to its catalog of scale models. The winner of the latest stop is a 1969 Buick Riviera turned into a head-turning lowrider. Owned by Mario and Nora Zamudio of Los Angeles, the big coupe is finished in a color called Pagan Gold and fitted with bright wire wheels. The husband-and-wife team spent four years working nights and weekends to build the Riviera. They removed the exterior trim pieces to achieve a cleaner look, spent a considerable amount of time detailing the engine bay and fitted a hydraulic suspension system. The interior received the custom treatment as well. Pagan Gold accents on the dashboard complement the exterior, there's an aftermarket steering wheel with three bright spokes, and the beige and brown upholstery finishes to the look. Readers familiar with Riviera models from the 1960s will notice that some of the switches aren't original; they're used to control the hydraulic suspension. Power for this Riviera comes from the original 430-cubic-inch (7.0-liter) V8, which was rated at 360 horsepower and 475 pound-feet of torque in 1969. It spins the rear wheels via a three-speed automatic transmission, and we bet it sounds excellent. One Buggy Mud Muncher Raptor View 13 Photos This eye-catching Riviera will move on to the semifinal round this fall, where it will compete against previous winners for the chance to get scaled down into a Hot Wheels model. The list of past winners is stunningly diverse: it includes a Volvo-powered 1968 Volkswagen Beetle, a kei truck turned into a monster truck, and a 1973 Toyota Celica powered by a General Motors-sourced V8 and nicknamed Tokyo Trans Am.

2020 Buick Encore drops more powerful 1.4-liter four-cylinder option

It's not just Chevrolet Equinox, Terrain and Traverse crossovers and Cadillac CT6 enjoying the engine and trim switcheroos this spring. Based on the order guide, CarsDirect reports that the Buick Encore, Buick's most popular model by far, will lose one of its two engines. The 2019 Encore offers a 1.4-liter four-cylinder in two guises: one with 138 horsepower and 148 pound-feet of torque, the other with 153 hp and 177 lb-ft and stop/start. The more powerful version will not be an option on the 2020 Encore. The upgraded motor is a $250 option, but only after spending an additional $2,600 to move up to the Sport Touring trim, or shelling out $6,100 to reach the Essence trim. Aggressive deals could make the higher trims more economical, though; at the time of writing, the Sport Touring Encore includes $3,250 cash allowance, making it $650 less expensive than the base Encore 1SV. The more powerful 1.4-liter engine also delivered better gas mileage, with buyers getting one more mile per gallon in combined driving. Even so, buyers didn't dig it. In comments to CarsDirect, a Buick spokesperson said those purchasing 2019 Encores have only chosen the burlier motor 12 percent of the time. The weak take-rate could end up doing Buick an easy favor. The Buick Encore GX is expected to make landfall on U.S. shores sometime this year, riding on a different platform than our present Encore, and bringing a longer wheelbase with it. It will slide into the lineup between the $23,200 Encore and $31,995 Envision. This is all hypothetical at the moment, of course, but that seems a perfect place to insert the 153-hp 1.4-liter as an exclusive standard feature.
