Semi-autonomous Cadillac CT6 has Batman's seal of approval

Earlier this year, Cadillac pushed the launch of its Super Cruise semi-autonomous technology back to 2017, but it looks like the automaker is still hard at work testing the system on its vehicles. Our photographers snapped a CT6 sedan with what appears to be the Super Cruise technology in broad daylight. The CT6 in the pictures, ignoring the massive equipment on the car's roof, appears to be stock. The barely camouflaged vehicle has more sensors on the front fascia and a black rear bumper, but other than those points, looks normal. Getting back to the massive piece of equipment on the CT6's roof. There's no way to definitively state what it is, but there appears to be four cameras on the corners of the rack. A sensor or camera is also fitted to the right side mirror, which is slightly camouflaged. With all of the wires from the roof going into the vehicle, there's a chance that the massive blacked-out piece of equipment on the roof could be used to gather data. While the equipment looks extremely scientific, someone at Cadillac must have a sense of humor, or be a huge fan of DC Comics, as a Batman's logo is prominently displayed on the roof-mounted gear. Cadillac announced its Super Cruise semi-autonomous technology two years ago. The system will be able to speed the car up, keep the vehicle in its lane, and slow it down. The goal, in 2014, was to introduce the technology in two years (2016), but the automaker delayed the tech until 2017.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Cadillac SRX likely to see next-gen built in China

Here's some shocking news to no one: People love crossovers, including those living in China. Since introducing the Cadillac SRX there in 2009, the model's sales have gone through the roof. Now, the brand is considering moving some production of the next-generation model in China to eliminate import tariffs and make it an even bigger player in the market.
According to a recent report in The Wall Street Journal, the crossover is leading Cadillac's Chinese growth, despite its US-equivalent price of over $67,000 after the country's high import tariffs. The CUV's sales are up 23 percent there so far this year, and it's responsible for over 40 percent of the brand's sales. John Stadwick, General Motors' VP of sales, service and marketing in China, told the WSJ that GM could "very possibly" build the next-gen model there.
The SRX is Cadillac's golden goose in China, and it just keeps pushing the brand's sales forward. "It's the vehicle that took us out of being a small niche in the market," said David Caldwell, Cadillac Communications Manager, to Autoblog. Before the CUV, Caddy was selling a little over 20,000 cars a year there, but partially thanks to the crossover's success, the brand sold 50,000 vehicles last year and could reach 60,000 this year. "The SRX is the most popular Cadillac in that market," he said.
