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:

2022 Buick Envision mostly costs a little less than in 2021

When Buick gave the world the second-gen Envision for the 2021 model year, the brand also gave Buick shoppers big discounts, cutting $1,700 from the entry-level Preferred trim's price compared to 2021. Buick's done the same on a smaller scale for 2022, albeit this time the brand made it an exchange, not a freebie. Pricing for the 2022 Envision after the $1,195 destination charge, as well as the differences from 2021, is: Preferred FWD: $32,695 ($300 less) Preferred ST FWD: $34,140 ($180 less) Preferred AWD: $36,345 ($1,550) Preferred ST AWD: $37,790 ($1,670) Essence FWD: $36,795 ($400 less) Essence ST FWD: $38,290 ($230 less) Essence AWD: $38,595 ($400 less) Essence ST AWD: $40,090 ($230 less) Avenir FWD: $41,045 ($550 less) Avenir AWD: $42,845 ($550 less) Buick's publicized list of changes for the 2022 Envision are the addition of a new Sapphire Metallic exterior color, and the Sport Touring package now including the "ST" logo embroidered on the front seat headrests and alloy pedals for all trims, plus contrasting red stitching on the Essence ST trim. What Buick left out, as GM Authority reports, is that some previously standard equipment is now optional, explaining the discounts of a few hundred bucks. Buyers need to buy a new $200 Safety Package to get blind spot and rear cross traffic alerts, which used to be standard with the Driver Confidence Plus suite. Powered lumbar for the driver's seat is also a new option that was formerly standard, bundled with different items and costing a different amount depending on trim. The real shocker is the four-figure price leap tacked onto the Preferred all-wheel-drive trims. In 2021, it cost $1,800 to send power to the rear axle. For 2022, it costs $3,650 to get AWD on the Preferred, but the AWD option on Essence and Avenir trims hasn't budged from $1,800. We aren't clear on the reasons for the change. Every Avenir is powered by a 2.0-liter turbocharged four-cylinder with 230 horsepower and 258 pound-feet of torque, shifting through a nine-speed automatic transmission. Related video:
