Buick really wants us to know the new Cascada convertible won't leak

Quality testing on the factory floor is nothing to joke about. Automakers need to make sure the work being done is up to snuff, and that means some extensive checks. For Buick, that means using a lot of water for each of its Cascada convertibles. Each vehicle that rolls off the floor is subject to a high-pressure, ten-minute soaking that sprays nearly 20 gallons of water from each nozzle during every bath, just to guarantee the fabric roof hasn't sprung any leaks. For some reason, Buick has chosen to show off this testing with the help of what we imagine is the Gorton's Fisherman's baby cousin. Check out the strange testing video, available up top.

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.

2018 Buick LaCrosse Avenir gets dash of flash

The 2018 Buick LaCrosse Avenir continues the rollout of the top-trim Avenir line, joining the Enclave. They use the same strategy: package some extra features as standard and give the vehicles more design flair. On the outside, the LaCrosse Avenir gets shiny chrome mesh grilles and Avenir badging, just like the Enclave. Two types of wheels are available on the LaCrosse, either 19-inch pieces finished in "Pearl Nickel" or 20-inch versions finished in "Midnight Silver." Inside, there is exclusive chestnut brown leather interior. The Avenir logo is stitched into the headrests of the seats and is displayed on the door sill plates. Aside from the visual tweaks, the Avenir trim adds a bunch of standard features. Among the convenience items are navigation, a sunroof and a Bose sound system. It also features the nine-speed automatic transmission hooked up to the 310-horsepower V6. But items such as the trick all-wheel-drive system and continuously adjustable suspension are still options. Pricing hasn't been announced yet, but expect it to be more than the $42,090 of the next highest-trim LaCrosse Premium with the V6. And Buick expects it will sell plenty of these cars, since it also revealed that 90 percent of LaCrosse buyers choose the top two trims out of the four available. The car goes on sale early next year. Related Video: Featured Gallery 2018 Buick LaCrosse Avenir View 10 Photos Image Credit: Buick Buick Luxury Sedan buick avenir
