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.

Chevrolet Malibu gets across-the-board price cuts, hopes to dig out of slump

To say that things aren't going well for the newly redesigned 2013 Chevrolet Malibu is a pretty sizable understatement. Reports have been swirling about the Malibu getting an emergency design refresh, less than a year after its introduction, as well as having its production at the Fairfax Assembly Plant halted twice already this year for excessive inventory. Now, Motor Trend is reporting that the midsize sedan will be receiving price drops across the board ranging from $300 on a number of models up to $770 on the 1LT trim; offsetting some of MSRP drop, though, the destination charge has increased from $760 to $810.
Without destination, the entry-level Malibu LS now starts at $21,995, which is still about $300 more than a Honda Accord and about $300 less than the segment's top-selling Toyota Camry. This new pricing also drops the price of the Eco, 2LT and 3LT trims by $300. The LTZ trim has dropped by $415, meaning that the Malibu's top dog now starts at just under $30,000, excluding destination.
Here are the new starting prices for all eight of the Malibu trim levels compared to the previous prices for the 2013 model year (including destination):
