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.

Buick version of Equinox/Terrain CUV spied testing... with autonomous gear?

Let's get the most pressing bits of this story out of the way right off the bat: What we see here appears to be a new compact crossover from Buick. According to the spy photographer, this machine may be a little bit smaller on the outside than the current Chevrolet Equinox and GMC Terrain 'utes, which makes sense since recent rumors suggest GM's small crossovers will migrate to a new platform that will mark a convergence between the automaker's Delta (Chevy Cruze, Buick Verano) and Theta (Equinox, Terrain) platforms. This Buick would likely use this new D2UX platform.
We've been expecting Buick to unleash a crossover to slot between the very small Encore and the very large Enclave, and various rumors have indicated that the model may be known as either the Anthem or Envision. It's worth mentioning that Buick had planned, back in 2009, to release a vehicle in the compact CUV market, but abandoned those plans after a particularly poor reception.
And now for something completely different... Take another look at the spy shots above, and pay special attention to the cylindrical device mounted to the vehicle's roof. We can't say for sure what it is, but our spy photographer opines that it looks quite a bit like the 360-degree Lidar camera equipment used by Google for its autonomous cars. Is General Motors working with Google on autonomous car technology? We don't know, but you can definitely consider us intrigued.

Why Buick's Encore wasn't a Chevy

Buick is taking a gamble with its 2013 Encore. General Motors' near-luxury brand has enjoyed great success attracting conquest buyers to its larger Enclave crossover, but it has never offered something quite like this small CUV.
Very early signs suggest that the gamble might be working. According to Mark Reuss, President of General Motors, the automaker expected about 1,500 initial orders from its dealers for the Encore, but it's tracking closer to 9,000 units. Alluding to the fact that historically, Buick has shared similar products with GM's other brands, Reuss says that Buick dealers are "thrilled to have an exclusive." The automaker already markets almost identical models in other markets as the Opel/Vauxhall Mokka and Chevrolet Trax, but The General's other brands won't offer a twin to the new baby Buick.
The new Encore is based on the Gamma architecture that underpins the Chevrolet Sonic, and it shares the economy car's available turbocharged 1.4-liter four-cylinder engine. With standard front-wheel drive and available all-wheel drive, GM says its Encore will be pitted against competitors like the BMW X1 and Audi Q3, both of which are much more expensive but also much more powerful.
