Cadillac ATS-V and Mercedes-AMG C63 S pitted Head to Head

Our favorite (and only) Autoblog-alum-turned-Motor Trend staffer is back with another Head to Head video, this time pitting the Cadillac ATS-V with the Mercedes-AMG C63 S. This performance machine shootout is ostensibly a way to figure out which of these new super sedans will earn the right to go toe-to-toe with the undisputed champion of its segment, the BMW M3. In reality, it's just a really good excuse to put three of the hottest sedans on the market on video at the same time... and there's certainly nothing wrong with that. Jonny Lieberman spends time in each of the two new challengers on the road, picking apart their powertrains, chassis and driving dynamics on the kinds of twisty roads drivers of these cars will relish. Then, he hands the keys off to Randy Pobst, who sort of acts as an unmasked version of a certain tame racing driver, except that he talks and has a personality. 0-60 and quarter-mile times are equated, braking performance is measured and scores are tallied before the two sport sedans end up at Willow Springs raceway. Interestingly enough, the car that proves (just slightly) faster at the race track isn't the car that wins the comparison. Curious? We're not going to spoil it for you. Check out the video, above. Then, for more action of these two machines, check out the videos just below.

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.

Cadillac Celestiq previewed as a flagship luxury electric car

Last year, our Autoblog Green editor, John Beltz Snyder, got a sneak peik of GM's upcoming electric car roll out. No photos were given, but he described them in great detail. Now we finally get our own peek at one of those cars, the Cadillac Celestiq flagship sedan. Sadly, we don't get a particularly clear look, since Cadillac is only teasing the car at this point, but it's better than nothing, and better than most teasers. We get a top-down shot that reveals the car will share some key cues with the Lyriq crossover EV. Most obvious is the rear with the boomerang taillights and fastback roof, which is a glass unit separated into four pieces. Each piece can be individually adjusted for transparency, and it appears they can be illuminated as well. The front also appears similar to the Lyriq with a geometric grille covered in a transparent panel. The grille looks significantly larger, though. It also features illumination like the crossover. We also get a look at the interior, which prominently features a full-width screen for instruments and infotainment. There appears to be a screen in the center console/stack that can control functions including the roof panel illumination. According to Snyder, the interior also has extensive wood and metal trim intermingling with nifty ambient lighting. Cadillac didn't say much about the mechanical aspects except the basics. It will use GM's Ultium battery technology that will be shared with other products such as the aforementioned Lyriq and the GMC Hummer EV. It will also feature four-wheel steering as well as all-wheel-drive, undoubtedly courtesy of dual motors, one front and one rear. Cadillac previously confirmed that the Celestiq is headed for production. We also suspect that some of the fancy features such as the screens and multi-panel glass roof could make it to production. This is because it's meant to be a halo product showing off the ultimate in luxury and technology from the brand, and it could have a price tag larger than $200,000. We're expecting Cadillac to fully reveal the Celestiq in a few months, but it could be a while before the production version hits the road. The Lyriq isn't going on sale until late next year, and we would bet the Celestiq wouldn't come ahead of it. Related Video:
