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.

Opel Insignia OPC getting facelift. Will the Buick Regal GS see it, too?

We've seen spy shots of the base Opel Insignia wearing facelifted front and rear ends, and now it appears that the more potent OPC version will be benefitting from a nip/tuck, as well.
The front bumper has been redesigned, incorporating new air intakes - toned-down versions of the model's signature fangs - as well as a new grille. Out back, there will be minimal changes to the overall fascia, most likely stuff like slightly redesigned taillamps, and inside, these spy shots show a larger navigation/infotainment screen sitting atop the center console.
This is all well and good for the Insignia, but we're wondering how these changes will impact North America's Buick Regal GS. No, it may not share the same powertrain punch as the Euro-spec OPC, but visually, the cars are nearly identical. When questioned about possible changes for the GS, a Buick spokesperson told us that the automaker "can't comment" on any changes at this point. Even so, we wouldn't be surprised if some small changes come our way in the next year or so.

Leno recalls '90s showdown with Tim Allen and his mullet

Not many of us have buddies with garages full of classic cars, but that isn't the case for Jay Leno and Tim Allen. Of course, one of the advantages for two guys with such vast collections is occasionally getting to pit their cars against each other. The two comedians did just that in the mid-'90s with a burnout battle on The Tonight Show between Allen in a race-prepped Mustang and Leno in a drag racer. After some time away from regular television, Leno is returning to the airwaves with a Jay Leno's Garage series premiering on Oct. 7 (tonight) at 10:00 p.m. ET on CNBC. Let this clip serve as another taste of what to expect for the new TV show's mix of comedy and cars. After reminiscing about the old days in a gorgeous garage, the comedians get into two modern machines to reprise the classic challenge – after a little trash talk anyway. Don't worry because the YouTube series isn't going anywhere, though.
