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.

Opel to electrify all model lines by 2024, speeding PSA transition

What do you see in the Opel logo? That's right, a lightning bolt. As the German automaker dramatically restructures its future plans, electric cars are in the core of Opel's survival. With attempts to stop leaking money, Opel is speeding up its secession from GM technology, launching nine new models by 2020 with the aim to complete transition to PSA hardware by 2024, leaving only two Opel platforms. This is all part of Opel's freshly announced PACE turnaround plan, which is crucial for the company's survival, according to CEO Michael Lohscheller. "PACE will unleash our full potential. This plan is paramount for the company, to protect our employees against headwinds and turn Opel/Vauxhall into a sustainable, profitable, electrified, and global company," says Lohscheller. Competitiveness will be improved by reducing per-car costs by 700 euros, and by cutting marketing costs by 10 percent. Regarding Vauxhall's future, the statement still includes the British brand. When the Opel sale agreement was reached between PSA and GM in March, the plan was to start implementing PSA technology in 2019, completing the transition in eight years, as Automotive News says. The new business plan is noticeably faster. By 2020, with full access to PSA's electric tech, Opel would have a fully electric next-generation Corsa hatchback and a PHEV version of the Grandland X SUV, which is already based on Peugeot's 3008 model. Currently, there are nine Opel platforms and 10 engine families. By 2024 there should be two platforms and four powertrains; the number of diesel engines in use remains to be seen, and all product lines would include an electrified model. There would be an SUV and a midsize vehicle based on PSA's EMP2 architecture, with the former built in Eisenach — formerly known as the town that built East German Wartburg cars before its Opel era — and the latter built in Russelsheim, where Opel HQ is located. The Russelsheim hub will become PSA's global "competence center," where all Opel/Vauxhall vehicles would be engineered — not Paris. Plans include avoiding any factory closures or personnel layoffs. The PACE statement also mentions Opel's entrance to all of 20 new export markets, with a specific mention of China and Brazil, countries which have traditionally seen Opels sold as Chevrolets. Will the United States be included in that export plan?

Autotrader picks best cars for 2015's college grads

Summer is here and the school season is winding to a close. That means millions of students will be graduating college and (hopefully) entering the workforce. For many, that will mean buying a new car suited to the new stage in life into which they will now be embarking. That can be a bewildering choice, especially for someone who's never bought a car before. Fortunately, Autotrader has come up with a short list of recommended cars – new and used – which it recommends to the graduating class of 2015. Among the site's top choices are some compelling crossovers and hatchbacks, including the Buick Encore, Chevy Trax, and Jeep Renegade, as well as the Honda Fit, Nissan Versa Note, Mazda3 and Fiat 500. Can't stretch to buying new, or don't see the point? Autotrader has also identified the Toyota Camry, Ford Fusion and even the Lexus IS as smart buys in the certified pre-owned category. "Any time someone goes through a major life change, such as graduating college, they need to determine if their current ride makes sense for their lifestyle, from both a financial and functional perspective," says Autotrader editor Brian Moody. "For example, while that hand-me-down SUV from your parents was nice when you turned 16, you may want to opt for a safer, more fuel-efficient car as you transition into the working world."
