Opel Cascada is Europe's Buick convertible [w/video]

As we reported earlier, there has been much speculation regarding a Buick convertible of sorts. The most ringing endorsement of this conjecture comes today from General Motors Europe, as the new Opel Cascada has debuted on the interwebs. Opel calls the four-passenger Cascada an "athletic, glamorous midsize convertible." With a length of 4,697mm (185 in.), the Cascada is as long as an Audi A5, to which GM has said it would be slightly larger.
The Cascada, which is Spanish for waterfall, features a cloth convertible top that retracts in 17 seconds and at speeds up to 50 km/h (31 mph). The Cascada features a 1.4-liter turbo gas engine, 2.0-liter turbodiesel with 165 horsepower and a range-topping 1.6-liter turbocharged Ecotec engine that puts out 170 horsepower and 280 Nm (207 lb-ft). Power is sent through either a six-speed manual or six-speed automatic transmission.
According to GM, the Cascada will also come rife with luxury and tech features. In addition to adaptive forward lighting and ergonomic heated front seats, the convertible will feature Opel Eye, which is a front camera that can recognize traffic signs and incorporates lane departure warning and forward collision alert.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

2021 Buick Envision is a vision of Buick's future that's shockingly stylish

Allow us to introduce you to the new and much improved 2021 Buick Envision. Don’t let the handsome shape and sharp design fool you. This compact crossover is a Buick. The Envision has been a frumpy and rather boring looking crossover since its launch for the 2017 model, and now GM has remedied that sticking point. This new made-in-China (the first Buick sold in America that was assembled there) crossover is full of sharp edges, muscular lines arcing through the body and crisp lighting fixtures. ItÂ’s verging on European in nature. If this is a hint of things to come at Buick, we are quite optimistic for the future of its crossover designs now that the cars are dead. “The 2021 Envision will be lower and wider, with premium proportions and striking styling designed to combine the expressiveness of a car with the practicality of an SUV,” said Helen Emsley, executive director, Global Buick and GMC Design. Perhaps youÂ’re hoping for additional details? We only have a few. Buick says it will be powered by a 2.0-liter turbocharged four-cylinder, and shifting duties will be handled by a nine-speed automatic transmission. ItÂ’s likely the same 2.0-turbo that makes 252 horsepower and 295 pound-feet of torque in the outgoing Envision. ThereÂ’s no word on the 2.5-liter naturally aspirated four-cylinder model, but itÂ’s likely being dropped from the lineup. There are no interior photos, but itÂ’ll have a 10-inch infotainment screen in the center that comes with Apple CarPlay and Android Auto functionality as standard equipment. There will also be a number of safety and driver assistance features tacked on as standard including lane-keeping assist, forward collision warning with automatic emergency braking and pedestrian detection, rear parking sensors and GMÂ’s safety alert seat that pulses directionally for alerts. Some options include a 360-degree camera, front parking sensors, rear cross-traffic alert, blind-spot warning, head-up display and GMÂ’s rearview camera mirror. Buick also says the Envision will be available in their top-tier Avenir trim. Other details will have to wait for later in the year, as Buick says all will be revealed at some point down the road. Consider this a preview with a few tasty bites of info about whatÂ’s to come. For now, weÂ’re liking the direction that Buick is taking this crossover. Related video:
