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.

GM recalling 1.5M cars in China for faulty bracket

General Motors and its Chinese partners have announced their second recall in the People's Republic this year, following a 2,653-unit recall of the Cadillac SRX earlier this year. This latest recall affects nearly 1.5 million cars built between 2006 and 2012. It's not explicitly stated, but as there's no movement from the US NHTSA, we suspect that the cars in question were all Chinese-built rather than imports.
The vast majority of the affected vehicles are Buick Excelles (pictured), with 1.2 million units being recalled over a faulty bracket that's meant to secure the fuel pump. The Excelles in question were built between 2006 and 2012, while an additional 250,000 Chevrolet Sail superminis, built between April 2009 and October 2011, are being recalled for a similar reason.
According to the PRC's Administration for Quality Supervision, Inspection and Quarantine, the faulty bracket could crack and potentially cause a fuel leak.

2014 Buick Regal priced from $29,690*

Buick has announced pricing for the refreshed 2014 Regal. The base model offers a 2.0-liter, turbocharged, 259-horsepower, four-cylinder engine for $30,615 (*after $925 delivery and destination fee). The standard turbo can be replaced by Buick's eAssist mild hybrid system for $32,485. The electrified powertrain delivers 36 miles per gallon, in place of the turbo's 30 mpg on the highway.
The big powertrain news for 2014 is the inclusion of an all-wheel-drive system for an extra $2,175. Marking one of the few uses of all-wheel drive on a Buick car, the new Regal AWD has an electronic, limited-slip differential and a HiPer Strut front suspension, which is the same front arrangement used on the hot, front-drive Regal GS.
Speaking of the Regal GS, it's not so hot for 2014. It sports the same 259-horsepower engine as the standard Regal, but offsets that with a wealth of standard, optional or flat-out exclusive equipment like active dampers, Brembo brakes and a Bose stereo. Prices (all including the $925 fee) start at $37,830. Like the standard car, the GS will be available with all-wheel drive for the first time, bringing it a bit more in line with its cousins across the pond - Opel Insignia OPC and Vauxhall Insignia VXR. Prices for the GS AWD start at $40,195.
