2018 Buick Enclave: How engineers made it larger, lighter, more sophisticated

Buick used the unveiling of the 2018 Enclave at the New York Auto Show to introduce its new range-topping Avenir sub-brand to the world. With fancier interior finishes and exterior details, it's Buick's latest effort to make itself a proper luxury brand (or perhaps re-establish itself as such). However, lost in the Avenir song and dance is the fact that the 2018 Buick Enclave is a (very) long-awaited all-new model regardless of the trim level one selects. Like the Chevrolet Traverse upon which it is based, the new Enclave is bigger than the vehicle it replaces but considerably lighter, by about 400 pounds. "We told every engineer, 'get your job done, but then take the weight out,'" said engineer Rick Spina as we hovered next to his larger yet lighter creation. His team therefore set about taking a little bit of weight out from just about everywhere, from using additional aluminum in the suspension to varying the thickness of the frame (thicker in places that needed to be stronger, thinner and therefore lighter in places that didn't). Only about 100 pounds came out of the body with the rest coming from elsewhere. Not only will the reduced weight improve fuel economy (Buick-estimated at 19 mpg combined with FWD versus 18 for the 2017 model) and presumably the old Enclave's rather ponderous handling, but it should only make things easier for the new powertrain: General Motors' now-familiar 3.6-liter V6 and its latest nine-speed automatic. With 302 horsepower and 260 pound-feet of torque, Buick says the new engine will need 7.2 seconds to reach 60 mph with FWD or 7.5 seconds with AWD. That's a second quicker than before. Besides acceleration, towing is also bumped up by 500 pounds to 5,000. For those models with all-wheel drive, the Enclave has the same basic system featured on range-topping versions of the Buick LaCrosse. Besides power being sent front and rear, it can also differ from right to left in the back, although Spina is quick to point out that capability is for traction-enhancing purposes rather than sporty, handling-enhancing torque-vectoring ones. Buick owners already appreciated the Enclave for its quietness so the engineers decided to take it that much further. This included altering the exhaust, improving body sealing (there are triple door seals), including active sound deadening and utilizing advanced materials that absorb sound as opposed to simply being thick, dense and heavy enough to keep it out.

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.

It's official: GM selling Opel-Vauxhall to Peugeot-Citroen group for $2.3B

It's a Brexit for General Motors. GM is selling off its Opel and Vauxhall unit, it confirmed today, ending 90 years of automobile production in Europe, and nearly two decades of losses from that division. The deal was announced on the eve of the Geneva Motor Show. The focus for GM now becomes North America and China. "This was a difficult decision for General Motors," CEO Mary Barra said. "But we are unified in our belief that it is the right one." "For GM, this represents another major step in the ongoing work that is driving our improved performance and accelerating our momentum. We are reshaping our company and delivering consistent, record results for our owners through disciplined capital allocation to our higher-return investments in our core automotive business and in new technologies that are enabling us to lead the future of personal mobility." The buyer is French automaker PSA Groupe, maker of Peugeot and Citroen as well as its DS luxury sub-brand. The $2.3 billion deal will make PSA the second-biggest European manufacturer after Volkswagen, with 17 percent of the market share. "We want to create a European automotive champion," said PSA Groupe Chairman Carlos Tavares. "We will totally unleash the potential of the Opel and Vauxhall brands." Tavares gave assurances that jobs would not be lost in the deal. "We respect all that Opel/Vauxhall's talented people have achieved as well as the company's fine brands and strong heritage. We intend to manage PSA and Opel/Vauxhall capitalizing on their respective brand identities." The two companies have agreements for PSA to continue to supply some Holden and Buick models; it's not yet clear exactly how this will work, as Opel models form the basis for several of Buick's core products, including the Encore small crossover and Regal sedan. PSA also is purchasing GM's financing operations in Europe as part of the deal. GM may invest in PSA shares in the future, and the two companies may collaborate on electric and fuel-cell vehicles as part of GM's joint venture with Honda. The sale of Opel and Vauxhall brings GM's global brand total down to eight, including three that are specific to the Chinese market. Buick GM Citroen Opel Peugeot Vauxhall 2017 Geneva Motor Show
