Reuss says Cadillac CT6-based Buick could happen

Could the upcoming Cadillac CT6 and its Omega platform spawn a Buick variant? According to General Motors' product chief Mark Reuss, it could potentially be in the cards, but "not yet." "We're working on that," Reuss told Automotive News at the 2015 New York Auto Show. While there hasn't been a large, rear-drive Buick on dealerships since the Roadmaster in 1996, the company gave a big hint that it could head in that direction with the Avenir Concept, shown earlier this year at the Detroit Auto Show. As Automotive News explains, a rear-drive Omega-platform Buick could be a real hit in China, where consumers buy 13 Buicks for every one Cadillac. That move would be a big help to GM's bottom line, too, as it'd significantly increase the Omega platform's economy of scale. If a large Buick based on the CT6 were to head to China, though, it likely wouldn't be a simple case of badge engineering (thank God). Reuss hinted to Automotive News that while the mixed-material construction of the CT6 platform "is very flexible," doing an "identical version of that platform or not is a different conversation." What are your thoughts? Should Buick adopt the Omega platform for an Avenir-based sedan? Should that vehicle be sold here in the US, or should it be a China-only offering? Have your say in Comments.

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.

Buick Electra E4 and E4 GS Ultium-based EVs introduced in China

China leads the way with Buick's revival, this month seeing the Trishield brand introduce another Ultium-based EV in two flavors for the Asian market. First comes the Electra E4, the crossover-coupe version of the Electra E5 that emerged from hiding in March. We know the formula — a little lower, a little shorter, a littler wider than the traditional sibling, with a steeper slope in the roof and a much faster backlight. The E4 wears a different front fascia design and touts subtle shifts like a single DRL instead of the dual DRLs on the E5. It goes a bit further with dual spoilers out back, a design trend found on decadent crossovers like the Aston Martin DBX and Genesis GV70 Coupe Concept.  The E4 is touch larger than our Buick Envision, the Chinese Electra about 7 inches longer, an inch wider, and 2.4 inches lower than the Envision, on a wheelbase 4 inches longer. The interiors hew to the design shown in the E5, with a bit more flash added. The same EYEMAX 30-inch, 6K curved screen forms the heart of the Buick Virtual Cockpit. The carmaker says front passengers get 39.9 inches of headroom in the E4, and there is "customer-pleasing headroom and knee space for second-row passengers," everyone bathed in light from the 12.9-square-foot low-radiation panoramic roof. It has 28 bins and cubbies for storage and 15.6 cubic feet of cargo room.  Underneath the skin, the entry-level powertrain has a 65-kWh lithium iron phosphate (LFP) battery powering a motor on the front axle making 241 horsepower and 243 pound-feet of torque. Based on China's test cycle, range is estimated at up to 329 miles. For now, the Electra E4 is only available with front-wheel drive.   Then there's the E4 GS, the first EV to merit Buick's Gran Sport designation. It's distinguished from the regular E4 with tweaks like a black diamond grille, black mirror caps, Night Bronze accents outside and in, 20-inch wheels hiding six-piston Brembo brakes on the front rotors, and illuminated sills. The GS starts with the same FWD drivetrain as the plain E4, but adds an AWD trim as well that's powered by a larger 79.7-kWh battery and makes 283 hp and 343 lb-ft. The front-driver can hit 62 miles per hour in 7.6 seconds. The AWD model cuts that sprint time to 6.2 seconds and increases range to an estimated 385 miles. Top speed for both drivetrains is 112 miles per hour.
