Opel director Sedran to succeed Docherty as Chevy Europe boss

When longtime General Motors executive Susan Docherty announced she would be stepping down from her post as the head of Chevrolet and Cadillac in Europe, there was some idle chatter that plans for the creation of a new global overseer position for the Bowtie brand was behind the move. And while US sales chief Alan Batey has indeed assumed control of Chevy worldwide since her departure announcement, Docherty's vacancy is being filled after all, with Opel chief strategist Thomas Sedran taking up the reins.
That's according to Automotive News, who reports that Sedran will be tasked with pulling Chevy out of a sales funk, much of it pegged on Europe's stagnant auto industry, which has sunk to a 20-year low. AN notes that Chevy's EU sales plunged 32 percent to 57,584 units through the first five months of 2013, but the everyday value brand is faring worlds better than Cadillac, which has sold just 167 units in Europe over the same time period.
Sedran, 48, has been in the auto industry for over 20 years. Most recently, at Opel he had been working on long-term plans for the marque, and was appointed to the brand's management board in April of last year. Prior to joining GM, Sedran was employed as a management consultant for AlixPartners, where he worked closely with Opel for six years. Sedran will assume his new duties beginning July 1.

2013 Cadillac ATS 3.6 AWD

All-Wheel, All Right
There is no escaping the luxury all-wheel drive empire Audi has built for itself over the past 15 years. While nearly every high-end marque has at least one offering with power at all four corners, the hardware can't help but play second fiddle to Ingolstadt's Quattro kingdom. Leather-lined all-wheel drive is simply Audi the way minimum wage is an English degree. But General Motors seems hell-bent on raiding as many established fiefdoms as possible with the 2013 Cadillac ATS. Engineers and designers made no secret of the fact that the baby Cadillac was penned specifically to take on the BMW 3 Series, but Audi should be no less concerned about the newest luxury prince from Detroit.
GM has been stuffing all-wheel drive systems under their vehicles for years, but the effort hasn't come without nasty side effects. Unfortunate understeer, extra ride height, smallish wheels and porky curb weight meant opting for all-wheel drive was like signing your driving pleasure's death warrant. Would you like polished brass or brushed nickel hardware for your right foot's coffin, sir?

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.
