Cadillac teases production ELR ahead of Detroit Auto Show

General Motors has just confirmed that the 2014 Cadillac ELR will make its official debut next month at the 2013 Detroit Auto Show. We've already seen the ELR testing earlier this year using the same range-extended electric drive system as the Chevrolet Volt, and based on the shadowy image above, we're happy to see that the coupe's styling has stayed pretty true to 2009 Converj Concept.
The two-door ELR will be built alongside the Volt at GM's Detroit-Hamtramck plant starting later next year. Aside from this info, Cadillac has remained tight-lipped on the specific details of the car. But all that will all change on January 15.
Until then, all we have to offer you is the press release posted after the jump.

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 ELR getting massive discounts, some up to $14,000

Well, that didn't go as planned. General Motors had marketed the Cadillac ELR extended-range plug-in as a premium version of the Chevrolet Volt with some Caddy refinements. Now, it looks like that premium, at least from a price standpoint, is shrinking. Shoppers in a number of states are reporting that GM and its dealers are discounting the ELR in order to move more off dealer lots. The issue is that few people are biting at the official price tag of about $76,000, so GM has started offering as much as $8,000 worth of dealer and customer incentives, Transport Evolved reports. More recently, dealers in states such as Florida, Texas and Maryland are offering discounts in the $12,000-to-$14,000 range, and that's before any federal and state plug-in incentives kick in. It's not difficult to guess why. Through the first half of the year, GM sold fewer than 400 ELRs. Last month, Caddy moved just 97 units, or about as many as Tesla sells of its Model S in a day. Perpahs recent spy shots that reveal a test ELR that appears to up the sportiness quotient, with touches such as larger wheels and brakes, will also help sales.
