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.

General Motors posts record earnings, but global sales fall

General Motors started the year with record success. The automaker's $2.7 billion in adjusted earnings before interest and taxes was its highest ever in in the first quarter of 2016, up from $2.1 billion in from the same time period a year earlier. Net income grew to $1.95 billion, which was more than double the $953 million in the same period last year. The company's figures also beat analysts' predictions, according to the Detroit Free Press. Despite the financial growth, global sales actually decreased by 2.5 percent to 2.36 million vehicles. "We're growing where it counts, gaining retail share in the US, outpacing the industry in Europe and capitalizing on robust growth in SUV and luxury segments in China," CEO Mary Barra said in the company's financial announcement. GM did well in North America with an adjusted EBIT of $2.3 billion, up from $2.2 billion last year. Sales in the region also grew 1.2 percent to 800,000 vehicles. According to The Detroit Free Press, the company has been especially successful at selling more expensive models in the US. The company's average vehicle was $34,600 in Q1, about $3,000 more than the industry average. Elsewhere in the world, GM also showed improvement. Europe practically broke even after losing about $200 million last year, and Opel and Vauxhall sales grew 8.4 percent to more than 300,000 vehicles for the quarter. South America only lost $100 million, which was half as much as Q1 2015's $200 million loss. China remained flat at $500 million of income. Cadillac volume jumped 6.1 percent there, and Buick's deliveries increased 22 percent, thanks to the Envision crossover's success. GM Reports First-Quarter Net Income of $2.0 Billion 2016-04-21 EPS diluted of $1.24; First-quarter record EPS diluted-adjusted of $1.26 First-quarter record EBIT-adjusted of $2.7 billion GM Europe posts break-even performance DETROIT – General Motors Co. (NYSE: GM) today announced first-quarter net income to common stockholders of $2.0 billion or $1.24 per diluted share, compared to $0.9 billion or $0.56 per diluted share a year ago. Earnings per share diluted-adjusted for special items was a first-quarter record at $1.26, up 47 percent compared to the first quarter of 2015. The company set first-quarter records for earnings and margin, with earnings before interest and tax (EBIT) adjusted of $2.7 billion and EBIT-adjusted margin of 7.1 percent.

Buick Encore GX fuel economy out, 1.3L more efficient than 1.2L

EPA fuel economy ratings for the 2020 Buick Encore GX are out, the most powerful engine taking the overall trophy. The new, slighty-less-compact subcompact crossover comes with a turbocharged 1.2-liter three-cylinder as its base engine, putting out 137 horsepower and 166 pound-feet of torque. Available solely with front-wheel drive and with a continuously variable transmission, the powertrain gets 26 miles per gallon in the city, 30 on the highway and 28 combined. The optional engine is a turbocharged 1.3-cylinder with 155 hp and 174 lb-ft. Mating it to the CVT in front-wheel drive guise returns the best fuel economy in the Encore/Encore GX family, being 30 city, 32 highway, 31 combined. That's spot on GM's prediction last year for combined fuel economy. Buyers who opt for the 1.3-liter with all-wheel drive — the engine costing an additional $395, the drivetrain a $2,000 upgrade — get a nine-speed automatic transmission, that combo returning 26 mpg in the city, 29 mpg on the highway and 28 mpg combined. Among luxury front-wheel drive entries, the 2020 BMW X1 sDrive28i gets 27 mpg combined utilizing an eight-speed automatic, the Lexus UX 200 gets 33 mpg combined with a CVT. Among less the expensive options, the Nissan Kicks returns 33 mpg as well through a CVT, the Mazda CX-30 rated at 28 mpg combined and employing a six-speed auto. The Encore once offered two versions of its turbocharged 1.4-liter, but is now left with the lesser-powered unit producing 138 hp and 148 lb-ft, paired with a six-speed automatic. Fuel economy with front-wheel drive is 25 city, 30 highway, 27 combined; with all-wheel drive, that shrinks by one mpg across the board to 24 city, 29 highway and 26 combined. The Encore GX is scheduled to hit dealership sometime this spring. Related Video:
