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 version of Equinox/Terrain CUV spied testing... with autonomous gear?

Let's get the most pressing bits of this story out of the way right off the bat: What we see here appears to be a new compact crossover from Buick. According to the spy photographer, this machine may be a little bit smaller on the outside than the current Chevrolet Equinox and GMC Terrain 'utes, which makes sense since recent rumors suggest GM's small crossovers will migrate to a new platform that will mark a convergence between the automaker's Delta (Chevy Cruze, Buick Verano) and Theta (Equinox, Terrain) platforms. This Buick would likely use this new D2UX platform.
We've been expecting Buick to unleash a crossover to slot between the very small Encore and the very large Enclave, and various rumors have indicated that the model may be known as either the Anthem or Envision. It's worth mentioning that Buick had planned, back in 2009, to release a vehicle in the compact CUV market, but abandoned those plans after a particularly poor reception.
And now for something completely different... Take another look at the spy shots above, and pay special attention to the cylindrical device mounted to the vehicle's roof. We can't say for sure what it is, but our spy photographer opines that it looks quite a bit like the 360-degree Lidar camera equipment used by Google for its autonomous cars. Is General Motors working with Google on autonomous car technology? We don't know, but you can definitely consider us intrigued.

Junkyard Gem: 1962 Buick Electra 225 4-Door Sedan

Buick built its first Electras as 1959 models, with Electra production continuing unabated through 1990 (after which the Park Avenue trim level took over as the model name, much as the Malibu trim level designation had shoved aside the Chevelle model name in 1978). Some of the handsomest Electras were the second-generation models, built for the 1961-1964 model years, and today's Junkyard Gem is one of those cars. I'd always assumed that the Buick Electra took its name from the daughter of Clytemnestra and Agamemnon in Greek mythology, because the people who named cars back then were forced to read Euripides and Sophocles as undergrads. In fact, the car was named after Electra Waggoner Bowman Biggs, a Texas heiress and sculptor who married the brother-in-law of Harlow Curtice, who ran the Buick Division before being promoted to president of General Motors in 1953. How did she feel when the last Electra rolled off the assembly line in 1990? The junkyard is full of history, if you know where to look. The 1959-1960 Electra had enormous tailfins, angled something like the ones seen on the same-year Chevrolet Impalas. This Electra generation ditched the fins but kept much of the general Space Age spirit of its predecessor. The Electra lived on the same platform as the Cadillac DeVille and Oldsmobile 98 from start to finish, and it was the most expensive Buick available in 1962. The MSRP of this one was $4,051, or about $41,462 in 2023 dollars. The engine in this one was present when it arrived at U-Pull-&-Pay, but a junkyard shopper grabbed it within a couple of days of arrival. It would have been a 401-cubic-inch (6.5-liter) "Nailhead" V8, rated at 325 horsepower and a whopping 445 pound-feet of torque (keep in mind that these are gross, not net, power numbers). The Nailhead's small valves meant that it wasn't much good for high-rpm use, but its big torque was perfect for moving two-ton land yachts. The final Nailheads were installed in 1966 Buicks. Every production Electra ever built came with an automatic transmission, and the 1959-1963 models received the extremely smooth and alarmingly inefficient Dynaflow (known as the Dual-Path Turbine Drive for 1962). Originally developed for use in the 1943 M18 Hellcat tank destroyer, the Dynaflow was considered a two-speed automatic but drove more like a CVT with two selectable drive ranges.
