Cadillac to Corvette: You’re not getting our twin-turbo V8 engine

NEW YORK — Cadillac president Johan de Nysschen bluntly shot down rumors his brand's powerful twin-turbo V8 is also headed for the Chevy Corvette. Speaking Wednesday at the New York Auto Show, he said: "Just quit the speculation it's headed for Corvette. It's not." The 4.2-liter V8 cranks out 550 horsepower and 627 pound-feet of torque in the Cadillac CT6 V-Sport, which debuted at the show. With that kind of performance and the fact the engine will be hand-built at the General Motors Performance Build Center in Bowling Green, Ky. — at the Corvette factory — led enthusiasts to presume the engine would eventually be under the Vette's hood. De Nysschen, however, argued the engine will also focus on levels of refinement, rather than the Corvette's raw, visceral dynamic. "I think Corvette wants a different kind of character," he said. In fact, the V8 is set to be only for Cadillacs, de Nysschen said, giving the luxury brand its first exclusive engine in years. "It's a matter of being a thoroughbred luxury car," he said. "It's really only a luxury brand that could recoup this [development] cost." A version of the engine making 500 hp and 553 lb-ft will also be used in other Cadillac models. De Nysschen declined say which vehicle will get the engine next. The new V8 uses a "Hot V" configuration more common to German performance cars, and has direct injection, electronic wastegate control, active-fuel management and stop-start technology. It teams with a 10-speed automatic transmission and fits either rear- or all-wheel drive systems. With a new mid-engine Corvette — and potentially more versions of the existing generation Vette — on the horizon, speculation pointed to the sports car getting a twin-turbo powerplant of some sort (V6 rumors also have floated), and the Cadillac 4.2-liter seemed to fit on paper. According to de Nysschen, that won't be the case. Still, even though the Cadillac boss says this specific engine won't go to Corvette, it's hard to not think some version of this engine, perhaps in a different displacement, could find its way under the hood of the Vette at some point in the future.

Cadillac ParkWhiz app helps avoid endless circling to find parking

General Motors recently launched an app for its vehicles called Marketplace that includes various apps that let you order and pay for things from your car. The company is continuing to add apps to Marketplace, and the latest sounds quite useful. It's called ParkWhiz, and it will be available on Cadillacs. Basically, it lets you find and pay for parking from your car. In more detail, ParkWhiz will let you find parking in 250 cities. The app shows locations that have spaces available and which are full, along with prices for all of them. You can then select one and pay for it for however long you'll use it. You can even reserve parking in advance in case you're going to a busy event. The big benefit here is that you should be able to eliminate a lot of cruising around looking for spaces. That will save you time and money. Additionally, this could save you from having to go really early to an event to find decent parking. It's a handy sounding app, and fortunately, if you don't have a Cadillac, you can get the app on your phone. The only downside to the phone app is that it's not built into the car's infotainment system.

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.
