2021 Buick Envision fuel economy revealed

Despite being revealed a few months ago, the 2021 Buick Envision has been lacking in in-depth details. But thanks to the EPA, we have a bit more information on the luxury crossover, specifically fuel economy. And it seems the new model is significantly more efficient than its predecessor. The only powertrain combination we have numbers for at the moment is the turbocharged engine with all-wheel drive. The Envision is expected to have a front-wheel-drive version, too, though an example with the old model's naturally aspirated four-cylinder is probably long gone. As for the turbo, all-wheel-drive Envision, it will get 22 mpg in the city, 29 on the highway, and 25 combined. That's the exact same as the old naturally aspirated, front-drive Envision, and it's an improvement of 2 mpg in town, 4 on the highway and 3 in combined driving over the previous turbo, all-wheel-drive version. As an extra bonus, the EPA notes that the new turbo Envision runs on regular gasoline, rather than premium like the old Envision. So not only will it use less gas, what it uses costs less. We're expecting the new Envision to go on sale early next year. While we know that the Envision will have a turbocharged engine, and the naturally aspirated one is probably discontinued, we don't know which engine it is. It could be an updated version of the old engine, which made 252 horsepower and 295 pound-feet of torque, or it could be the engine from the Cadillac XT4, which makes 230 horsepower and 258 pound-feet of torque. The latter seems more likely, since the XT4 gets similar fuel economy. A nine-speed automatic and front-wheel drive or all-wheel drive are also planned for the crossover. Related Video:

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

2018 Buick LaCrosse gets a mild hybrid model, lower price

Update: Buick provided us with horsepower and fuel economy figures. The text has been updated to reflect this. Buick is rolling out a variety of updates for the 2018 LaCrosse, including a new mild eAssist hybrid. Like the previous generation LaCrosse and Regal eAssist models, this one features a small electric motor and an equally small battery pack that together augment rather than supplant the gasoline engine. The motor, attached to a 2.5-liter four-cylinder engine, helps to make takeoffs smoother and provide additional torque on demand. The gasoline engine still does the majority of the work, though. Combined, the powertrain produces 194 horsepower and 187 pound-feet of torque. It will also allow the LaCrosse to get 25 mpg in the city, and 35 mpg on the highway. While the electric powertrain doesn't provide primary propulsion, it does come with other benefits. The small battery means the LaCrosse maintains a folding rear seat. The battery also provides power to accessories when the engine shuts off at a standstill. This mild hybrid powertrain will be the standard engine for all 2018 LaCrosses, and they come with a lower base price. The 2018 model will start at $31,415, which is about $1,500 less than the lowest priced 2017 V6 LaCrosse. The V6 will still be available as an option, and Buick has updated it, too. The 2018 V6 models will also all come with a new 9-speed automatic transmission. The new LaCrosses will go on sale this fall. Related Video: Image Credit: Buick Green Buick Hybrid Luxury Sedan
