How to hack a Buick Regal with CarKnow

If you own an Apple iPhone or Android device, perhaps you've been tempted to jailbreak or root it. This process gives you access to the the software's code, and can be used to make minor or drastic changes to its operating system. CarKnow, a company in Boston, is working applying a similar concept to the automobile.
Translogic recently took a look inside CarKnow to see just how it can tweak the computers inside a car and what sort of things can be done. As our transportation tech sister site explains, CarKnow basically created a digital duplicate of their Buick Regal in the cloud, while harvesting data generated to create custom apps and infiltrate the deepest function of their test car.
And before you freak out about people maliciously taking over your car, CarKnow's founder, Josh Siegel, stresses that it isn't quite so easy as driving up alongside someone. Take a look at the full video below to see just what it's like to jailbreak a car.

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:

Buick luxury sedan design sketch would make a great flagship

Over the Thanksgiving holiday General Motors posted a sketch of a futuristic Buick sedan to social media. In fact, the sleek wedge is just the latest in a series of illustrations that seem to point the way to a luxury EV coming in 2024 (for model year 2025). That's when Buick has promised its first fully-electric vehicle, with the promise that the entire lineup will be gasoline free.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) The sketch shows a low, long sedan that seems to be inspired (or perhaps served as the inspiration for) the Buick Wildcat concept revealed in June. However, there are significant differences as well. The sketch shows a profile that's more cab backward than the Wildcat's, with a gently sloping roofline that's more Audi A7 than the physical car's aggressive Nissan GT-R-like top.  The front end is less busy than the Wildcat's as well, with the chrome better integrated into the fascia and headlights. Similar brightwork appears on the rocker panels and on the fenders behind the wheel arches, cues the Wildcat concept lacks. Buick's updated logo sits at the end of a sporty BMW-esque trough on the hood. Of course, the exaggerated wheels have such little clearance they wouldn't really be able move or turn, much less survive a pothole, but we can forgive that artistic liberty. Other recent sketches shown on the GM Design account on Instagram show a more refined version of the same sedan, but without the Wildcat's Honda CR-V-esque taillights. Another super-luxurious coupe with hints of Syd Mead looks just as beautiful but is unbranded and may work better as a Cadillac. The Buick brand feels a bit redundant these days, but stunning designs like these could help differentiate the brand. The General has plenty of trucks and SUVs already. If it's going to foist crossover after crossover at us, maybe the Buick division could stand out as the sedan-and-coupe-only brand. Related video:
