Junkyard Gem: 1982 Buick Riviera Diesel Coupe

After appending the Riviera name to various cars during the 1950s, Buick finally made the Riviera a model in its own right for the 1963 model year. Seven more generations of Buick's rakish personal luxury coupe followed over the next 36 years, but only one ever had an oil-burning engine available from the factory. Today's Junkyard Gem is one of those cars, a vividly purple '82 Riviera with 105 horses of Oldsmobile diesel power under its hood, found in a Denver-area self-service boneyard recently. Starting in the 1966 model year, the Riviera had been living on the same platform as the Cadillac Eldorado and Oldsmobile Toronado, both of which featured radical front-wheel-drive powertrains that used longitudinal V8s powering the front wheels via sturdy chains. However, despite the common platform, the Riviera alone kept the then-traditional front-engine/rear-drive setup, making it something of a corporate oddball for the next 12 years. Then General Motors decided to downsize the Eldorado/Toronado platform for the 1979 model year, and the Riviera got those cars' front-wheel-drive rig at the same time. Sales of the smaller Rivvy were strong, no doubt due in large part to certain geopolitical events that sent gas prices skyward and caused fuel rationing and gas lines. Back in the late 1970s and early 1980s, diesel fuel was much cheaper than gasoline in the United States. Mercedes-Benz and Peugeot had done reasonably well selling diesel-engined cars here during the 1970s, and so General Motors developed a diesel-burning version of the Oldsmobile 350-cubic-inch (5.7-liter) V8 engine. As was typical of naturally-aspirated automotive diesels of the time (every modern car's diesel engine is turbocharged), horsepower was miserable but torque was strong; the engine in this car was rated at 105 horses and 205 pound-feet. The 5.7 diesel first showed up in the Riviera for the 1981 model year. The base engine was a 4.1-liter version of the Buick V6, while the oil-burning Olds cost an extra $924 (about $3,206 in 2023 dollars). A comfortable and smooth-riding Riviera with the cheap fill-up price and long range of diesel sounded great, even if you had to line up with Freightliners and Peterbilts to get to a pump, but there were problems. Oh, so many problems! Oldsmobile's 350 V8 had been around since 1968 and it had proven to be both reliable and powerful.

2022 Buick Enclave revealed with refreshed styling, more standard features

Buick gave us a sneak peak at the 2022 Enclave back in January, but it officially pulled the sheet back Wednesday to reveal the extent of its updated styling and detail a few updates to its feature content, including a new suite of standard safety tech.  We can now better see the various exterior styling touch-ups, including a larger, more pronounced grille, new head- and taillights, and more angularly sculpted front and rear bumpers. The Avenir's exterior treatment was also updated to incorporate the new elements. The changes aren't too dramatic, but Buick did enough to make the 2022 visually distinguishable from previous years.  The new standard safety suite is Buick's Driver Confidence Plus package. It includes automatic emergency braking with pedestrian detection, lane keeping assist with lane departure warning, blind spot monitoring, forward collision warning, rear park assist, rear cross-traffic alert and automatic high-beams. Buick's midsize crossover is still powered by a standard 310-horsepower V6 with optional all-wheel drive. The range-topping Avenir model includes an adaptive suspension and unique styling elements.  Despite our previous expectations, the Enclave's cabin didn't really get an upgrade apart from the standard safety items listed above. Buick did not include pricing information in Wednesday's announcement, so you can look forward to yet another update before the 2022 Enclave goes on sale later this year.  Related video: 2021 Buick Envision Running Footage

Buick Encore production increased to lift supply by 50%

Trying to zero in on the Buick Encore leads us to the conclusion that the only place it really fits is in buyers' driveways. Every member of its so-called competitive set – we've read everything from the Ford C-Max to the Nissan Juke to the Volkswagen Tiguan to the BMW X1 – is so different in small yet fundamental ways that the Encore neatly slinks between them all, and with 48,892 sales in 2014, it doesn't stop slinking until it reaches consumer garages. That success, and preparation for the aggrandizing of the compact CUV segment, is why General Motors is upping production for the US market by 50 percent. Analysts keep predicting there will be more shoppers for tiny crossovers, and that's why those that don't have them are getting them. Yet the Encore came out in 2013 before people realized the power of the segment, and it has substantially out-performed GM and observer expectations: analysts predicted 18,500 US sales in 2013 and 25,000 in 2015; in 2013 we wrote, "We admit it. We have no earthly idea how this whole thing is going to shake out." It shook out 31,046 sales in 2013, puffing that number up by more than 50 percent last year. GM thinks that this year it will it will go from Buick's third-best-selling vehicle to its best-selling vehicle. GM wants that to continue, what with the Honda HR-V, Jeep Renegade, and Mazda CX-3 on the way. Dealers say they'd sell more if they could get them, and the four-month lead time at the moment between a dealer ordering and taking delivery – about double the normal time – creates a handicap. Plants in Mexico, Korea, and Spain will hive off production to bolster US inventory to keep the "downsizing empty nesters" who love it, happy. Seeing as the coming competition is falls meaningfully outside the Buick's combination of traits, there's a chance its popular tale can continue.
