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's bold design means small space gains, a few big losses

So far, every preview we've had of the 2021 Buick Envision compels us to believe that it isn't playing in the same league as the current Envision, nor is it playing the same sport. The chiseled, crisp exterior is matched by an interior that, in pictures at least, sends a genuine premium message. GM Authority got early intel on dimensions for the new crossover, the numbers showing that the only close relationship between the current and the new Envision is in size. According to GMA, the 2021 Buick will be 185.5 inches long on a wheelbase of 109.4 inches, it'll stand 74.1 inches wide without mirrors, and 64.6 inches tall. Front and rear tracks are matched at 63.3 inches. That makes the new version 1.8 inches longer than the current five-seater, with a wheelbase stretched 0.9 inches, while width is 1.7 inches wider but overall height is 2.2 inches lower. The track has been expanded by 1.3 inches front and back. The four-trim lineup will be base, Preferred, Essence and Avenir. Buick's website pegs the current Envision at the single curb weight of 3,755 pounds. GMA writes that the new car comes in at 3,685 pounds in base form, or 3,932 in top Avenir trim. Those could all represent weights for front-wheel-drive models. AWD will be optional on all but the base 2021 Envision. The price for edgier design is a tiny cut in interior room in front. In the coming crossover, front headroom shrinks 0.4 inches to 39.6 inches, front legroom shrinks by 0.5 inches, front shoulder room goes down by 0.3 inches. Front hip room gains 0.7 inches, however, Occupants in the row behind get a tiny bit more space in two dimensions, rear headroom going up 0.4 inches, rear legroom by 1.8 inches, Rear shoulder room gets shaved 0.7 inches, and those haunches on the 2021 model take a bite out of rear hip room, that spec dropping by 5.7 inches to 47.4.  Cargo room sees a slight dip, too, there being 25.2 cubic feet of space behind the second-row of seats compared to 26.9 feet available now. The gap grows with the rear seats down, the coming Envision able to swallow 52.7 cubic feet behind the front row, the current Envision managing 60 cubic feet.  When product starts showing up on dealer lots, we're to expect a 2.0-liter turbocharged four-cylinder under the hood with 230 horsepower and 258 pound-feet of torque, shifting through GM's nine-speed automatic transmission. GMA believes pricing will start around $34,000, which would be about $500 more than the current Envision.    

Junkyard Gem: 1985 Buick Skyhawk Custom Coupe

General Motors began building cars on the compact J Platform in 1981, and J-based machinery stayed in production all the way through the 2005 Chevrolet Cavalier and Pontiac Sunfire. The best-known of the J-cars in North America was always the Cavalier, but The General's Pontiac, Oldsmobile, Buick and even Cadillac divisions each sold their own Js here. The Buick version was the Skyhawk, built for the 1982 through 1989 model years. Here's a sporty '85 Skyhawk coupe, found in a Northern California boneyard recently. The Custom trim level was the cheapest version of the Skyhawk in 1985, and the two door was the most affordable configuration (midgrade Skyhawks were Limiteds and the T-Type was at the top of the Skyhawk pyramid that year). The MSRP on this car started at $7,512 (about $21,220 in inflation-adjusted 2022 dollars), making it the least expensive new Buick offered for sale in the United States in 1985. The Skyhawk name had been used on the Buick version of the Chevrolet Monza during the 1970s. The Chevrolet-badged sibling of this car was much cheaper, with the list price of the base '85 Cavalier coupe set at $6,872 (around $19,410 today). There were cheaper new Chevrolets that year, of course; a new Chevette cost just $5,470, while the Isuzu-built Spectrum was $6,295 and the Suzuki-built Sprint a skinflinty $5,151. The base engine in the Custom and Limited was this 2.0-liter SOHC straight-four rated at 86 horsepower. A turbocharged 1.8-liter version with 150 horses was available for an extra 800 bucks ($2,260 now). A four-on-the-floor manual transmission was standard equipment in the 1985 Skyhawk, but the buyers of most of these cars insisted on automatics. The price for this one was $425 ($1,200 today). A five-speed manual cost just $75 ($210). Velour-ish upholstery in Bordello Red (Buick didn't use that name) was all the rage during the 1980s and well into the 1990s. This car's interior looks pretty nice, considering where it's parked. Community Buick GMC in Iowa is still in business today. The five-digit odometer means we can't know how many miles were on this car at the end. I brought a Chicago-made 1950s Pho-Tak Foldex 30 film camera with me to the junkyard that day, as one does, and I photographed the Skyhawk on Kodak Portra 160 film. The irritatingly perky Skyhawk owners in this TV commercial appear to be about one-third the age of typical mid-1980s Buick shoppers.
