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.

One of the world's largest muscle car museums is auctioning off its cars

Rick Treworgy's Muscle Car City is one of the biggest collections of high-performance American cars in the world. With over 200 cars of mostly GM makes, it's a mecca for fans of the golden age of Detroit iron. Unfortunately, the museum will be shutting its doors for good on Jan. 17 and auctioning off most of its assets with no reserve. The collection is, to put it bluntly, astounding. Advertised as a combined 65,000-plus horsepower, it occupies a 60,000-square-foot retail space in Punta Gorda, Fla., in a former Walmart store. It make sense when you learn that founder Rick Treworgy made his fortune in the commercial real estate business. As a hobby, he began to amass a truly jaw-dropping collection of muscle cars, filling out a collection that often has every year of a particular model represented, or a grouping of the rarest and highest-performance option packages of that year or model. Often, Treworgy bought placeholders while scouring the country for even rarer versions. It helps that Muscle Car City also houses a showroom where unwanted cars are sold, as well as its own speed shop that stocks plenty of parts. There's even a '50s-style diner called Stingray's Bar and Grill. According to a 2014 episode of Car Crazy, Treworgy has 80 Corvettes alone, more than the actual Corvette Museum. Among them are 20 models from 1967, one of Treworgy's favorites. The rest span the decades from 1954 (he once had a '53 but sold it) to a recently acquired 2020 C8, which, according to The Drive, has only 300 miles on the odometer. You like Impalas? There are models of every year from 1958 to 1969. El Caminos? He's got 'em from 1964 to 1972. Novas? Every year from 1963 to 1970 is represented. Most are the more desirable examples of each breed, with four-speed transmissions, the biggest blocks, and unicorn option packages like a factory 1965 Z16 SS396 Chevelle, one of 200 that were ordered off-menu at Chevy dealerships. And don't even get us started on the Camaros, which include not one, but two COPO 1969s. Treworgy even owns the only known surviving example of a 1936 Chevrolet Phaeton, of which only seven were built. On top of it all, many of these cars are concours quality and have won awards at prestigious car shows. While it's sad to see a collection like this broken up, Treworgy told The Drive that he'd been planning to retire next year anyway. However, the COVID-19 pandemic sped up those plans, greatly reducing the number of visitors to his museum.

Is this GM's next electric crossover?

GM made headlines this week when CEO Mary Barra presented the company's electrification and automation plans at the Barclays Global Automotive Conference in New York. "We are committed to a future electric vehicle portfolio that will be profitable," Barra said, which could be taken as a jab at Tesla. In the presentation ( PDF here), though, we see a new vehicle in a slide titled "Leveraging existing BEV platform to expand in near term." The vehicle, seen above, accompanied the captions "New CUV entries" and "two entries by 2020." Is this a sneak preview of an upcoming electric crossover from GM? The image seems too realistic and intentional to be a random placeholder. If this is, indeed, an upcoming battery-electric CUV based on the Bolt, the question remains: Will it be a Chevy or a Buick? It has no visible badging, but it shares DNA from both brands. As Inside EVs points out, though, it does bear a resemblance to the Chevrolet FNR-X concept unveiled in Shanghai earlier this year. With two CUVs on the way, it's not unthinkable that there could be a version for each brand. In addition to this slide, the presentation includes plans for an "All new multi-brand, multi-segment platform" launching in 2021. The all-new modular battery system will cost less than $100 per kWh, providing higher energy density and faster charging. The platform will host at least nine different vehicles, including a compact crossover, seven-seat luxury SUV and a large commercial van. GM has said it will launch 20 new EVs by 2023, and that it targets 1 million EV sales per year by 2026. Many of those sales will be in China. Related Video:
