GM seeks national mandate for zero-emissions cars

DETROIT — General Motors says it will ask the federal government for one national gas mileage standard, including a requirement that a percentage of auto companies' sales be zero-emissions vehicles. Mark Reuss, GM's executive vice president of product development, said the company will propose that a certain percentage of nationwide sales be made up of vehicles that run on electricity or hydrogen fuel cells. GM says a nationwide program modeled on such a requirement in California could result in 7 million electric vehicles, or EVs, on U.S. roads by 2030. California wants 15.4 percent of vehicle sales by 2025 to be EVs or other zero emission vehicles. Nine other states, including Maryland, Massachusetts, New Jersey and New York, have adopted those requirements. In January, California Governor Jerry Brown set a target of 5 million zero-emission vehicles in California by 2030. The Trump administration criticizes California's ZEV mandate, saying it requires automakers to spend tens of billions of dollars developing vehicles that most consumers do not want, only to sell them at a loss. Reuss told reporters that governments and industries in Asia and Europe "are working together to enact policies now to hasten the shift to an all-electric future. It's very simple: America has the opportunity to lead in the technologies of the future." A national mandate also would create jobs and reduce fuel consumption, CO2 emissions and "make EVs more affordable," Reuss added. GM, the nation's largest automaker, will spell out the request Friday in written comments on a Trump administration proposal to roll back Obama-era fuel economy and emissions standards, freezing them at 2020 levels instead of gradually making them tougher. Under a regulation finalized by the Environmental Protection Agency at the end of the Obama administration, the fleet of new automobiles would have to get 36 miles per gallon by 2025, 10 mpg higher than the current requirement. But the Trump administration's preferred plan is to freeze the standards starting in 2021. Administration officials say waiving the tougher fuel efficiency requirements would make vehicles more affordable, which would get safer cars into consumer hands more quickly. GM on Thursday said it doesn't support the freeze, but wants flexibility to deal with consumers' shift from cars to less-efficient SUVs and trucks.

Buick could import Envision crossover from China

Reports about the Buick Envision's likely arrival in the US go back even before the midsize crossover's debut in China last year, but the brand still doesn't have a official decision about whether to bring it here. According to The Detroit News, the company is somewhat concerned about a poor consumer reaction to launching a Chinese-made model in this country. Even if Buick officials are slightly apprehensive about the public perception, the concerns might not hold back the Envision in US. An anonymous source also tells The Detroit News that the brand intends to launch the CUV early next year and wants to sell around 40,000 of them annually. However, the UAW is reportedly not happy about the possibility of a Chinese-produced model coming here. The Envision launched at the Chengdu Motor Show as a step between the compact Encore and three-row Enclave. Power comes from a 2.0-liter turbocharged four-cylinder with stop/start and 256 horsepower and 260 pound-feet of torque. Buick offers the CUV with a six-speed automatic and all-wheel drive. The interior features active noise cancellation and an eight-inch infotainment system. The Envision also seems like a natural fit for Buick in the US due to the obvious hole in its CUV lineup, and the abundant rumors suggest that the brand sees the possibilities for it. The company now needs to decide whether to take a chance here and offer a vehicle from China.

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.
