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.

2014 Chevy Malibu, Buick LaCrosse recalled over brake mix-up

The recall madness over at General Motors isn't letting up anytime soon, as evidenced by this latest call-back of 8,208 Chevrolet Malibu and Buick LaCrosse sedans. For those keeping track, this is the fifth recall that GM has announced in the past two weeks, not to mention the massive ignition-switch issue from earlier this year.
GM issued a statement saying these sedans are being recalled due to "possible reduced braking performance," according to Automotive News. The problem? Rear brake rotors may have accidentally been installed in the front brake assembly. And since both cars use more robust braking systems up front than out back, braking power could be reduced, increasing the risk of a crash.
Automotive News reports that, of the over 8,000 cars being recalled, about 1,700 are currently in the hands of customers, while the others are still in dealer inventory. GM is unaware of any crashes or injuries related to this problem. All of the affected vehicles are from the 2014 model year.

Buick Verano to go turbo-only for 2014?

If VIN tags recently posted online prove accurate, the 2014 Buick Verano may be getting a new base engine. Presently the Verano makes use of GM's 2.4-liter Ecotec four-cylinder engine in non-turbo trim; 2014 documentation appears to indicate that GM's entry-level luxury compact will instead feature a 1.6-liter turbocharged mill.
If this is the same engine seen in Europe, GM Inside News suggests it may offer 192 horsepower and 170 pound-feet of torque - useful improvements over the larger naturally aspirated mill's 180 hp and 171 lb-ft. More importantly, the downsized engine would likely improve on the Verano's current fuel mileage estimates of 21 city and 31 highway.
We like the Verano in both of its current iterations, but the 1.6 turbo engine sounds like a worthwhile upgrade if this reports turns out to be true. Plus, if more performance is your bag, baby, there's always the Verano's optional 2.0 turbo engine with an impressive 250 horsepower and 260 lb-ft from just 2.0 liters of displacement.
