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.

Junkyard Gem: 1997 Oldsmobile Eighty-Eight LSS Supercharged

Oldsmobile got terminated by The General in 2005, in part because the marketing suits decided that the first three letters of the marque's name made the cars undesirable to the under-75 set (never mind that 21st-century rappers continue to venerate Oldsmobiles). Not long before the demise of Olds, though, you could buy an Eighty-Eight with the supercharged L67 V6, known as the Luxury Sports Sedan or LSS. These cars are very rare today, but I spotted this '97 in a Denver self-service wrecking yard. These Eaton blowers are now so easy to find in wrecking yards that most of them go unpicked by customers. The going rate for this supercharger is about 50 bucks, because everyone who wants one already has a big hoard of the things. If you have ever wanted to drop a supercharger onto your crapcan race car's engine, now is the time. Performance was respectable for the era, with output of 240 hp and 280 lb-ft. The 3800 was the descendant of the ancient Buick V6, which debuted way back in 1962, so GM had had many decades in which to make it a dependable (though not very smooth-running) powerplant. Yes, you could still buy big ol' sedans with rear drums at the dawn of the 21st century. Did the LSS steal any sales from potential BMW or Mercedes-Benz buyers? Probably not many, though its $27,695 price tag must have looked pretty tempting when compared to that of the much slower $32,960 Lexus ES 300 in 1997. Right now is the best time to make a resolution you'll enjoy sticking with. The reviewers at Popular Mechanics were unable to break the first-year LSS.
