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.

Buick Velite is a not-so-Volt-like plug-in hybrid concept for China

Is the Buick Velite a Volt by any other name? That's a question worth asking after General Motors said that the Buick Velite concept vehicle will make its global debut at the Guangzhou Auto Show later this month. GM says the car "will provide a template for upcoming models being launched under the Buick Blue new energy vehicle strategy." Whether that means the Velite is a variant of the second-generation of the Chevrolet Volt extended-range plug-in is open to interpretation. Some automotive publications, including Autoweek, are saying that's the case, but GM China doesn't mention the Volt in its press release, only saying that the car is a "high-performance" plug-in hybrid vehicle. As we know, GM doesn't use the "PHEV" descriptor for the Volt, which makes us thing the Velite's powertrain is more like the Cadillac CT6 PHEV. Either way, the concept was developed by the Pan Asia Technical Automotive Center (PATAC), which is a joint venture between GM and Shanghai-based SAIC. As far as the name, GM has been shopping the Velite moniker around for a while now. The automaker first used Buick Velite for the convertible concept vehicle it showed off at the 2004 New York Auto Show. More recently, GM in 2014 filed to use the name for the US variant of its Opel Cascada four-seat convertible model, which debuted in 2013. As for the second-generation version of the Volt, that model appears to be gaining favor in the US. Domestic sales of the Volt through October have surged 64 percent from a year earlier to more than 18,500 units. The new version boosted its all-electric range by 40 percent to 53 miles while increasing its power output by 20 percent.

2016 Buick Cascada First Drive

Florida became a state in 1845. It is the third most populous state in the United States, home to the most-visited theme park in the world. It is where you'll find every convertible ever sold in the United States, be it a pasty white Infiniti M30 or a Lamborghini. And soon, many examples of the 2016 Buick Cascada will call it home. Florida is full of Buicks. Wonder if anyone bought a Rendezvous Ultra? It's in Florida. The Buick Reatta, the company's last convertible before this? Also there. Buick, however, is eager to get those who better remember Bush vs. Gore than Nixon vs. Kennedy to ask, "That's a Buick?" Which is how we arrive at the Cascada. The Cascada isn't so much a new Buick as a car that's new to Buick. It's been on sale for about three years as the Opel Cascada in Europe, along with badge-engineered siblings sold by Vauxhall and Holden in other parts of the world. Buick took that time to make several hundred changes to the Cascada for US consumption and then found it without many rivals. The Chrysler 200 convertible, Volkswagen Eos, and Volvo C70 would all be prime targets for the Cascada here, were they not all dead now. Buick's gamble is that these Chrysler, VW, and Volvo (also Saab, for that matter) customers are looking for somewhere to go next. The Cascada isn't so much a new Buick as a car that's new to Buick. One thing is certain: the Cascada is eye-catching to Floridians. I had no fewer than six people in Miami and Key West walk up to me and ask what kind of car it was, or even say, "That's that new Buick convertible, right?" Despite being three years old, the Cascada's looks have aged pretty well. And it's been spared many of the tacked-on details, like fake portholes and chrome wheels, that were adhered to the Regal when it made its trip over from Opel-land. Top up or down, the Cascada is attractive. Unlike the Audi A3 or BMW 2 Series convertibles (the former being the Buick's prime target), there's no abruptness to the design, no sharply ending lines. The Buick looks relaxed in a Palm Beach or Palm Springs way, even on the inside with the convincingly stitched dash top and standard heated leather seats (one of the pieces redesigned for the Buick). That being said, the pattern on the seat material is a misstep, looking like it was inspired by Aunt Flora's 1972 patio furniture. Then it's surprising that you don't exactly sink into the Cascada. While the seats are mounted low, they're not pillow soft.
