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.

Is Buick's surprise Detroit concept a Camaro-sized coupe?

Tomorrow night marks the unofficial start of the 2016 Detroit Auto Show. Keep your eyes peeled for a number of reveals, including a surprise debut from Buick. Yes, Buick. And we think it's going to be something really hot. According to a report from Bloomberg, the Tri-Shield's secret car could be a Camaro-sized sport coupe concept. As Bloomberg explains, it'd certainly gel with the impression the company is trying to put out – that it's no longer a brand for those with one foot in the grave. Introducing a sports coupe, even as a concept, could certainly reinforce that message. And if it happens to make production – which is not a certainty, Bloomberg's secret source says – it could certainly help Buick drive its average buyer age down from 59. Bloomberg doesn't offer any speculation on Buick's new coupe, but we have no problem making educated guesses. Our most reliable conjecture is this: it will ride on General Motors' Alpha platform, which underpins both the Camaro and the Cadillac ATS. And with a certain twin-turbocharged V6 in the GM stable, we've got an idea of what kind of engine could be shown. That speculation will have to suffice for now. But don't worry, we'll have official details, live images, and video tomorrow when Buick unveils its new concept in Detroit's Eastern Market.

Buick boss shuts down idea of importing Opel Adam

Anyone hoping for Buick to sell small city cars in America, you're not going to like this story. Buick boss Duncan Aldred has effectively ruled out importing the stylish Opel Adam city car for US drivers. Yep, this is us being bummed. Admittedly, the business case for Adam is not as strong as it used to be. Gas is cheap and consumers have fallen back in love with the idea of high-riding crossovers instead of efficient cars. That's why Buick sold twice as many teeny, tiny Encore CUVs in 2015 as it did its smallest car, the Verano. With that in mind, slotting in another car, let alone one below the Verano, isn't a great idea. Of course, Aldred didn't come out and say as much, even though he campaigned for a US-market Adam in the past. "I very much did feel when I came over that that could really help accelerate the Buick brand story," the executive told Automotive News at last week's New York Auto Show. "I don't see that as much. Whether the market shifted or the fashion nature of those cars has changed, I don't know. But I wouldn't be looking for a small, B-segment car today." That, friends, is a real bummer. Adding a car like the Adam, even in a small, captive-import capacity would add a real dose of fun to Buick showrooms and (we're guessing) would bring in younger foot traffic. Related Video:
