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.

Here's how Detroit is selling more luxury vehicles than Germany and Japan

Now there's an attention-grabbing headline, eh? Although the answer to the riddle - pickup trucks and SUVs - might be somehow deflating, the numbers involved deserve a going over. According to TrueCar's figures (click on the table to enlarge), six of the year's ten best-selling vehicles in the US that sell for a transaction price above $50,000 are body-on-frame, and the Mercedes-Benz E-Class is the only foreigner to crack the top five. Every enthusiast knows that pickup trucks are 'Murica's most popular vehicle by a colossal margin, and there have been plenty of reports about the popularity of luxuriously appointed trucks and SUVs, but compare these figures from TrueCar: 70 percent of Chevrolet Tahoe sales have a transaction price above $50K, and The Bowtie is expected to make $3.9 billion in revenue on 66,945 predicted high-dollar sales; 95.1 percent of E-Class sales break $50K, so the German company will make $4.0 billion on 67,006 predicted sales in that pricing sphere. It's about the only time you'll see the Tahoe ranked right next to Mercedes' bread-and-butter sedan. Ram is ahead of those two with $4.2B coming from $50K-plus sales. The Ford F-Series does almost as much revenue as the next three combined, with an expected $10.8 billion coming from sales of trucks over $50K - more than a quarter of the model's total sales, when a base F-150 can be had for about $26,000. Yes, the Germans make a lot more money on fewer sales, but considering the comparison, the bottom line isn't too troubled by such facts. Weighing like-for-like, the full-size Ford walks it in every category; elsewhere, the Chevrolet Silverado outsells the Ram, but the Ram outsells the Chevy by 6.7 percent above $50K. And for all the flak GMC takes over swapping out grilles, the Sierra also outsells the Chevy in the well-appointed segment, 16.1 percent of sales versus 11 percent – the Professional Grade brand is a huge profit center for The General.

Chevy Bolt, GM's 200-mile EV, could debut in Detroit

It's not news that General Motors is working on a $30,000 electric vehicle with a 200-mile range. Then-CEO Dan Akerson said as much back in 2013. What we've heard before is that this mystery EV will be based on the Chevrolet Sonic and will will arrive in 2017. So, if that's all correct, then it would make sense that confirmation of this plan would come at the 2015 Detroit Auto Show, which is just around the corner. And lookee here... The Wall Street Journal is reporting that GM will unveil a concept Chevy Bolt at the Detroit show on Monday. That name sure makes sense, too, since GM registered that trademark back in August. According to the Journal, the rumored numbers – 200-mile range, $30,000 price – are still what's expected. Some new purported details are that the battery will come from LG Chem, which also makes the Volt's batteries, and that the Bolt will be a crossover that could be sold around the world. This all smacks of a preemptive strike against the Tesla Model 3, which is also due around 2017. Currently, GM sells the Spark EV in limited areas of the US, despite a lot of excitement for wider availability. To sell a 200-mile EV for $30,000 means that GM and LG Chem will likely have drastically reduced the cost of making a big plug-in vehicle battery. What this means for the new Volt and GM's future plans is something we're more than a little excited about to learn more of on Monday, the same day that we get to see the redesigned Chevy Volt for the first time. Well, aside from the CES teaser. Green Chevrolet Crossover Electric 2015 Detroit Auto Show Chevy Bolt bolt
