GM CEO Akerson calls out Tesla, says Cadillac will compete on EVs

Cadillac will be taking on Tesla Motors, the underdog EV manufacturer that's seen heaps of critical acclaim and stock market buzz with its most recent sedan, the Model S. "If you want to compete head-to-head with Tesla, and we ultimately will, you want to do it with a Cadillac," Dan Akerson, the chairman and CEO of General Motors, told media in Washington, according to The Detroit News.
Akerson continued, telling The News, "We'll sell more Volts and lose less money on the Volts than they'll lose on the Model S." He also took time to point out that Tesla getting vehicles out to customers isn't a guarantee of success or permanence, using Fisker as an example, saying "Does anybody even remember Fisker? I mean, there were a number of them; they are all gone."
This strong talk from Akerson comes after Doug Parks, another GM exec, let slip that the Detroit-based manufacturer has an EV in the works that will cover 200 miles per charge and only cost about $30,000, a massive upgrade over similarly priced EVs that struggle to top 100 miles per charge. Until that vehicle arrives, though, GM is preparing the Cadillac ELR, a small coupe that, like the Volt with which it shares technology, uses a gas engine as a mobile generator to recharge the batteries. Akerson took aim at Tesla again, saying, "But I do think when the ELR comes out late this year, early next - it's certainly the same postal code as Tesla, but now we're going to move up. It's not going to be a mass-produced car."

Cadillac planning its own engines, halo cars

Cadillac is in the midst of some big changes. It's got a new chief executive. It's taking some distance from parent company General Motors and moving to a new headquarters in New York. And it's instituting a new naming scheme that will allow not only for a more clear progression in its lineup, but also for more models. But that's not the end of the story. Not by a long shot.
Speaking with Automobile magazine, Cadillac's new president Johan de Nysschen revealed his intention to develop several new models and powertrains. For starters, he does not want Cadillac to continue borrowing engines from the GM parts bin, but intends to develop a new range of engines specifically for the luxury automaker. The program will likely start with smaller-capacity engines but eventually lead to new V8s as well, taking the place of the long-serving Northstar engine that finally ended its lifespan a few years ago after some two decades of production. Along with other technologies, de Nysschen envisions possibly sharing these powertrains with other GM divisions, but developing them first and foremost for Cadillac.
The bigger question, however, is where those engines would go, and de Nysschen had some thoughts to share on that front as well. For starters, the former Infiniti and Audi exec sees room for an even bigger sedan above the upcoming new CT6 that will cap the current range. Maybe even two of them. But that's not all. Johan wants to see Cadillac get (back) into the sports car game with a new halo model or two - something it hasn't really done since the Corvette-based XLR roadster. A pair of new crossovers are also said to be in the works, flanking the SRX on both sides with smaller and larger models.

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.
