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.

Next-gen LaCrosse, Cascada convertible coming to Buick showrooms in 2016

It's difficult to overstate how significant the post-bankruptcy years have been for General Motors' Buick brand. Arguably the most improved American automaker, Buick has rounded out its range with an excellent compact in the Verano, a well-balanced midsizer in the Regal and a segment-busting mini-CUV, with the Encore.
Seeking to keep that momentum going, the next several years will see the brand address a trio of its most obvious issues. First and foremost will be a replacement for the aging LaCrosse, a vehicle whose only bit of attention since its 2009 debut was a very light refresh in 2013.
According to Automotive News, we should expect the next-generation LaCrosse to arrive late next year or early in 2016, as a 2016 model. AN expects big design changes, as Buick attempts to further the LaCrosse from its popular platform-mate, the Chevrolet Impala. The changes won't be so radical, though, as to do away with its front-drive architecture, as the latest version of the Epsilon platform will underpin the next LaCrosse. The 3.6-liter V6 is likely to carry on, although a smaller, budget-minded offering is also extremely likely (we'll eat our hat if it's not the 2.0-liter, turbocharged four-cylinder from the Regal, Verano and Cadillac CTS et al.).

Buick Velite 6 to come in PHEV, electric versions for China

In addition to the all-electric Enspire crossover concept revealed this week ahead of the Beijing Auto Show, Buick is adding a new production variant to its Velite series of electrified vehicles for China. It's called the Velite 6, a plug-in hybrid that will launch this year in Buick's largest market. A full-electric version, shown in the lead photo above at right, is coming later. Buick already sells a vehicle called a Velite 5 in China, which is essentially a rebadged Chevrolet Volt, only with a higher electric-only driving range. This one is based on the Velite concept PHEV introduced in late 2016 at Auto Guangzhou. The PHEV and battery-electric versions look nearly identical, with a wide stance, plenty of creases and a hatchback design that bears some similarities to the longer 2018 Regal TourX wagon. The Velite 6 uses two AC permanent-magnet synchronous motors, a lithium-ion battery and a 1.5-liter four-cylinder combustion engine. Buick says combined gas-electric driving range is 435 miles, which is 15 miles greater than the Volt. Buick will assemble what it calls the "new-generation" ternary battery pack at its new SAIC-GM Power Battery Development Center in Shanghai. The company says the Velite 6 electric vehicle "will adopt a new-generation pure electric drive system to offer customers a smooth, quiet and natural driving experience." Both models get the cloud-based Buick eConnect technology, which allows over-the-air software updates, real-time integration with China's WeChat social media network, and other digital perks. Owners will also be able to use their smartphone as the vehicle's key, and they can also authorize others to use the car through their phones. China has long been Buick's largest market, with more than 1.18 million vehicles sold in 2017 compared to just 219,231 in the U.S., and the country has established aggressive mandates for production of electric vehicles. GM has plans to add 20 new electric and fuel-cell vehicles globally by 2023. Related Video:
