GM intends to offer semi-autonomous vehicles by 2020

Prepare for a few years of technological saber-rattling, as the world's automakers begin pushing to bring self-driving cars to market. Earlier this week, Nissan announced that it aims to offer autonomous vehicles by 2020, while Google, BMW and several other marks are working on similar efforts.
General Motors is doing things differently, though. Rather than push for a fully autonomous car, it's continuing to refine its semi-autonomous Super Cruise, a product that we tested in April 2012 and that will eventually see use on some Cadillacs before trickling down to the rest of the General Motors family. Super Cruise, which is undergoing testing in the Cadillac SRX, doesn't take complete control out of the driver's hands. Rather, under a very specific set of circumstances on the freeway, it will marry the capabilities of things like lane departure warning and adaptive cruise control to allow the driver to take their hands off the wheel. All of which sounds a lot like the system Mercedes-Benz is launching on the 2014 S-Class.
The system is still in development, according to John Capp, GM's director of electrical controls and active safety technology. Now that that the biggest hurdle, steering control, has been cleared, GM's engineers can focus on things like teaching the system to adapt to differing road conditions and visibility levels. As we reported in 2012, Super Cruise is still befuddled in low-visibility situations or when road markings aren't particularly clear.

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.

Want to beat LA traffic? Chargers QB Philip Rivers has found a way

Slogging through traffic in Southern California is about as pleasurable as being slowly eaten by bears or being the awkward third wheel on a bad first date. It feels like it's never going to end. After the team relocated to Los Angeles from San Diego, Chargers quarterback Philip Rivers decided that three hours wasted each day in a car was too much. As The San Diego Union-Tribune reports, Rivers' rolling office makes his days more productive than ever. After deciding that he wasn't going to relocate his family to Orange County, Rivers was stuck with the prospect of either spending considerably less time with his children or skipping out on much-needed film work at the team's training facility (not really an option given his profession). Instead, he began investigating a number of options to make his lengthened commute slightly more viable and productive. First, he considered carpooling with a teammate. That was still too much of a pain. He looked at flying a helicopter, but unless it could land close to both his home and the practice field, it too was useless. A quick online search eventually led to the rolling footage review room you see here. Becker Automotive Design in Oxnard, Calif., builds these rolling offices for a wide range of customers. It sells modified Mercedes-Benz Sprinters, Ford Transits, and, in Rivers' case, a Cadillac Escalade with a raised roof. His needs were simple: a television and an HDMI input so he can hook up his computer. No fancy armor or recumbent exercise bicycle. His goal was to review game footage on his commute rather than slowly waste away behind the wheel of a car. Photos show a sea of leather and wood and a mini fridge, so it's not totally without niceties. Column | Philip Rivers' new ride allows him to stay home https://t.co/btwCEgIsFq pic.twitter.com/DHud3ho5UF — The Union-Tribune (@sdut) September 5, 2017 The Union-Tribune lists the price of the Escalade at about $200,000. That's not including the driver's salary. In 2015, Rivers signed a four-year deal with the Chargers worth $84 million, so he's not hurting for cash. If it increases productivity and saves the headache of being behind the wheel in traffic, we can imagine more people with means (and not just quarterbacks) will be opting for such daily transport.
