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.

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 Celestiq electric sedan could top $200,000

General Motors teased a slew of new electric vehicles last week at a media event where cameras weren’t allowed, and now thereÂ’s more news about the Celestiq, one of the two EVs in the pipeline for Cadillac. Reports suggest it wonÂ’t come cheap and will retail for at least $200,000. Wall Street Journal auto writer Mike Colias dished that detail, along with word of a mid-2020 launch, on Twitter, attributing it directly to Cadillac President Steve Carlisle. Cadillac has made no official mention of starting price for either the Celestiq luxury sedan or the Lyriq, an EV SUV that it has previously teased. A spokesman told Autoblog the brand wouldnÂ’t comment on future product speculation. Leftover scraps from Cadillac flagship ‘CelestiqÂ’ news: ItÂ’ll be hand-built in the hundreds per year, Caddy chief Steve Carlisle said. Price? Six figures Â… “and it wonÂ’t have a 1 in front of it.” Due mid-2022. — Mike Colias (@MikeColias) March 5, 2020 If true, the six-figure MSRP would make the Celestiq the most expensive Caddy ever assembled, at least outside of one-off coach builds and the presidential limo, vaunting it into the same class as brands like Bentley, Lamborghini and Rolls-Royce. By way of comparison, the limited-edition ultra-luxury 1957 Cadillac Eldorado Brougham four-door debuted with a $13,074 price tag, the most expensive car of its day and the equivalent of around $120,000 in todayÂ’s dollars. So what do we know about the Celestiq? For starters, itÂ’ll be a halo flagship hand-built in limited quantities somewhere in the Detroit area. Our reporters who saw the white four-seater describe it as having a long, fastback roofline, no side mirrors or visible door handles, with a long wheelbase, short overhangs and a tinted glass roof. A rendering of the interior showed an LED instrument cluster and infotainment display that stretches between both A pillars, with touchscreen interfaces on the rear of the front seats. It also reportedly features a hatch instead of a conventional trunk and styling cues from the Escala concept from 2016, shown above. Cadillac teased it as the “ultimate luxury experience” and said it would be highly customizable. Cadillac also showed off the Lyriq, the name itÂ’s given to its midsize electric crossover that it had previously promised to unveil in April, possibly at the New York Auto Show, if it manages to happen given the coronavirus.
