Cadillac CT6 gets a plug in Shanghai, will come to US

Don't call it the third coming of the Chevy Volt. The unsurprising debut of the Cadillac CT6 PHEV in Shanghai today has a powertrain that sounds an awful lot like the one that can be found in the Volt and the Cadillac ELR. The plug-in CT6 – identical to the CT6 that debuted in New York earlier this month – has an 18.4-kWh lithium-ion battery (just like the 2016 Volt) and offers an all-electric range of around 37 miles. It also copies the "Regen on Demand" feature from the new Volt and the battery cells "use the latest generation cell chemistry found in other GM plug-in vehicles." But Cadillac President Johan de Nysschen doesn't see the two powertrains as similar in at least one important way. General Motors calls the Volt and the ELR "extended range electric vehicles" (EREV) but in a statement, de Nysschen says that the plug-in hybrid CT6 is, "an ideal platform for Cadillac to offer its first plug-in hybrid." That GM is using the PHEV terminology rather than EREV is going to be important to some, even if the practical difference is only semantic. And yes, we all understand the irony of de Nysschen – the same guy who has a history of speaking ill of plug-in cars – hyping them now. Back when he worked for Audi, he said the original Volt was too expensive for what it offered and was thus, a car for "idiots." Speaking in Shanghai today, de Nysschen said the new CT6 PHEV was, "an EV without any of the disadvantages or range constraints," according to Automotive News. If the batteries are similar to GM's other EREV/PHEV cars, the CT6 powertrain is at least different. The ELR uses a 1.4-liter engine, while the new Volt has a 1.5-liter four-cylinder mill. The CT6, on the other hand, has a 2.0-liter turbo four-cylinder engine with direct injection. There is also an "all-new rear wheel electric variable transmission (EVT) with exclusively designed motors," that will give the CT6 PHEV, "smooth, spirited acceleration." The EVT is a two-motor-unit that uses three planetary gears. Maximum overall system output is 335 horsepower and 432 pound-feet of torque. Perhaps most interesting for American audiences is the fact that GM's press release, available below, makes multiple references to US-market sales of the PHEV. Official details on the EV range and fuel economy will be made available closer to the car's US launch.

Dealers mobilize to protect their margins from automaker subscription services

Six individual auto brands — Lincoln, Cadillac, Porsche, Mercedes, BMW and Volvo — have established or are trialing a vehicle subscription service in the U.S. Three third-party companies — Flexdrive, Clutch and Carma — run brand-agnostic subscription services. And three automakers — Mercedes-Benz, BMW, and General Motors — have also launched short-term rental services. Dealers, afraid of how these trends might affect their margins, are building political and lawmaking campaigns to protect their revenue streams. So far, three states are investigating automaker subscriptions, and Indiana has banned any such service until next year. It's certain that those three states are the first fronts in a long political and legal battle. Powerful dealer franchise laws mandate the existence of dealers and restrict how automakers are allowed to interact with customers to sell a vehicle. On top of that, Bob Reisner, CEO of Nassau Business Funding & Services, said, "Dealers and their associations are among the strongest political operators in many states. They as a group are difficult for state politicians to vote against." In California earlier this year, the state Assembly debated a bill with wide-ranging provisions to protect against what the California New Car Dealers Association called "inappropriate treatment of dealers by manufacturers." One of those provisions stipulated that subscription services need to go through dealers, but that item got stripped out when dealers and manufacturers agreed to discuss the matter further. In Indiana, Gov. Eric Holcomb signed a moratorium on all subscription programs by dealers or manufacturers until May 1, 2019, to give legislators more time to investigate. Dealers in New Jersey have taken their campaign to the state capitol, asking that the cars in subscription programs get a different classification for registration purposes. Automakers run the current subscription services and own the vehicles. Sign-ups and financial transactions happen online or through apps, leaving dealers to do little more than act as fulfillment centers to various degrees, with little legal recourse as to compensation amounts when they're called on to deliver or service a car. That's a bad base to build on for business owners who've sunk millions of dollars into their operations.

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.
