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.

Junkyard Gem: 2002 Buick Regal Joseph Abboud Edition

Ever since we saw that snazzy green 2000 Buick Regal GSE last month, with its supercharger and Monsoon Audio speakers, I've made it my junkyard-searching goal to find a genuine Joseph Abboud Edition Regal among the not-so-interesting Luminas and Vues in the GM sections of my local car graveyards. While this publication once stated that the Joseph Abboud Regal was "the low point of the brand" (in my view, the nadir was achieved with the Iron Duke-powered Skylarks of 1980-1985), my great love of designer-edition Detroit cars overrides any so-called rational opinions on the subject. It took less than three weeks of walking the aforementioned junkyard GM sections to find a Regal with the mark of the famous menswear company on the fenders. The heyday of designer-edition cars came during the 1970s, when Lincoln offered Continentals co-branded by Bill Blass, Givenchy, Pucci, and Cartier. At the same time, American Motors teamed up with Levi's and Oleg Cassini, and fashion-industry players continued to work with car manufacturers here and there after that time. It appears that the Abboud package got you nice leather seats with these monograms, plus the stylish fender badges. Otherwise, it was just a nicely-equipped but unspectacular late W-Body. For you GM trivia fans out there, the W platform stayed in production for an impressive near-three-decade span, from the 1988 Pontiac Grand Prix through the (fleet-only) 2016 Chevrolet Impala Limited. The final W-based Regals rolled off the assembly lines in 2005. This car has the 240-horsepower supercharged 3800 V6, so it's the GS version. You could get the Abboud package on the non-supercharged LS Regal as well. If you did, you got the better tires and suspension used on the GS. These Roots-type Eaton M90 blowers are by far the easiest superchargers to find and extract from a junkyard car. In fact, there's such a glut of these things at swap meets that the going price now hovers around 50 bucks. This car looks to have been in decent shape when it arrived in the junkyard. The original owner's manual was still in the glovebox when I found it. The 240-horse supercharged engine was Harley Earl's idea, turns out. He'd been dead since 1969, but that's a technicality. Some tips for selling the new Regal.

GM admits goal of 500,000 EVs by 2017 won't be met

After a little over four years of Chevy Volt sales, General Motors has a better handle on how many people it expects will buy cars with plugs. And it's less than the company thought back in 2012, when then-senior vice president of global product development, Mary Barra, said that GM expected to sell 500,000 "vehicles with electrification" by 2017. In a sustainability report released this week, GM says that half-million vehicle target will not be met but that it still, "believes the future is electric." In the report, GM says that, "For our commitment to electrification, our forecasted outlook currently projects us, along with the broader automotive industry, falling short of expectations for 2017. ... We continue to aspire to our stated goal." GM's electric lineup includes the Volt, the recently popular Spark EV, the slow-selling Cadillac ELR and upcoming Malibu Hybrid, CT6 plug-in hybrid and eAssist technology in the Buick LaCrosse and Regal. GM says it has 180,834 electrified vehicles on the road in the US today. In 2013, it had 153,034; 95,578 in 2012, and 39,843 in 2011. The company's next big plug-in vehicle will be the second-gen Chevy Volt, which is coming to market later this year, followed by the 200-mile Bolt EV coming, we think, in 2017. GM Employees on Mission to Transform Transportation Sustainability report outlines vehicle and manufacturing progress; sets new targets 2015-05-07 DETROIT – General Motors' just-released sustainability report chronicles efforts by the company's 216,000 employees to live out GM's newly defined purpose and values by earning customer loyalty, applying meaningful technology advances and improving the communities where it does business. These actions – led by CEO Mary Barra – further drive sustainability into the company's culture through building safer and smarter vehicles with less environmental impact. "GM will take a leading role in the auto industry's transformation as it undergoes an unprecedented period of change," said Bob Ferguson, senior vice president, GM Global Public Policy. "From GM's labs to its assembly lines, our people are driving the world to a better place through improved mobility." The company believes the future is electric, with billions of investment to support an all-in-house approach to the development and manufacturing of electrified vehicles. It now counts 180,834 on the road in the U.S – up from 153,034 in 2013.
