Cadillac CT6 beefs up with 400-hp twin-turbo V6

Cadillac's engine lineup is set to get a makeover led by the potent powerplants under the hood of the CT6. Our man Steven Ewing is onsite at an event in Detroit reporting all the details. Here's what we know so far: The CT6's top engine will be a 3.0-liter twin-turbo V6. It's the first twin-turbo with cylinder deactivation, which essentially makes the V6 able to convert to a V4 unit. Power will be 400 horsepower at 5,500 rpm and 400 pound-feet of torque at just 2,500 rpm. No word on what a potential CT6-V would get. The CT6 will also have a naturally aspirated V6 that Cadillac is claiming to be all-new. It's rated at 335 hp at 6,800 rpm and 284 lb-ft at 5,300 rpm. That's an improvement of 14 hp and nine lb-ft compared with today's 3.6-liter V6, and fuel economy increases nine percent. Cadillac says it's the highest output for a naturally aspirated V6 that's SAE-certified and runs on regular fuel. Both of these V6s will have stop/start technology and will be paired to with eight-speed automatic transmissions. The 3.6-liter V6 will also be used in the 2016 CTS and the 2016 ATS. Meanwhile, Ewing reports that Cadillac says the ATS-V is actually more powerful than initially announced, though there are no numbers to flesh that claim out as yet. The brand also plans to offer four- and six-cylinder diesel engines in various vehicles and new V8 options. The CT6 bows at the New York Auto Show. It will use an aluminum-intensive body that reduces weight by 198 pounds compared with a steel setup and continues Cadillac's creased design language used on the CTS and ATS models. The CT6 goes into production late this year in Detroit.

Jeff Gordon will come out of retirement to race new Cadillac endurance racecar

Jeff Gordon is not a man who takes well to retirement, apparently. That's not a surprise at all, given that we've been talking about his return to racing since almost the minute he retired in the first place. This year, he's taken the wheel for Dale Earnhardt, Jr., who is recovering from a concussion, several times already. So we shouldn't be too surprised to find out he's officially coming out of retirement – the twist is that it won't be in a stock car. Gordon has signed onto Wayne Taylor Racing, Motorsport.com reports, and he'll join Ricky and Jordan Taylor as well as Max Angelelli. Their ride will be the newly-revealed Cadillac DPi-V.R racer, a Dallara-chassis car powered by a 6.2-liter pushrod V8 loosely related, Cadillac claims, to the engine in the current CTS-V. You can read all about the DPi-V.R right over here. Remember, Gordon has a total of 93 NASCAR wins to his name, as well as four titles. He knows his way around Daytona pretty well, too, having won the 500 three times. He's also dabbled in endurance racing once before, in the 2007 24 Hours of Daytona with Taylor, Angelelli and Jan Magnussen in a WTR Riley-Pontiac car. They ended up on the podium, so you can say Gordon's inaugural and only outing in endurance racing so far was a success. It's been a decade, so we'll see if he's rusty, although knowing about how competitive champions are, we think he'll blow out the cobwebs and get right down to work. You can read Gordon's statement over at his personal site. Related Video:

Cadillac Escalade reportedly getting 200-hp bump from supercharger

Cadillac is preparing to supercharge the Escalade, according to a recent report. The body-on-frame General Motors SUVs that it shares its basic underpinnings with are allegedly in line to receive a big increase in power, too. Released for the 2021 model year, the fifth-generation Escalade eschewed downsizing and launched with a 6.2-liter V8 as its standard engine. It develops 420 horsepower and 460 pound-feet of torque when it's naturally aspirated, and Motor Trend learned from an anonymous source that the optional supercharger will increase the first figure to anywhere between 600 and 625. The eight's torque output will undoubtedly go up, too. The supercharged Escalade won't outgun the sold-out Dodge Durango SRT Hellcat, which gets 710 horses, but it will pack a serious punch. It doesn't sound like the V8 will require significant modifications to handle the extra power because the supercharger kit will likely be installed by dealers, not on the assembly line. This strongly suggests that it's more of a bolt-on job than one that requires taking the engine out and apart to install stronger connecting rods and forged pistons, for example. ECU tweaks will be part of the package, too, and the fuel delivery system may require some upgrades. Interestingly, Motor Trend learned from Texas-based Hennessey that the SUV's ECU is locked to tuners, which adds credibility to the report. Motorists who want more power will need to go through official sales channels, then. Bigger brakes and a firmer suspension won't be part of the package — at least not yet. The same source outlined a true high-performance evolution of the body-on-frame behemoth that will be quicker and tighter to drive. Oddly, it's not being developed by the engineers in charge of Cadillac's V-branded models, according to the report. If the report is accurate, we'll learn more about the supercharged Cadillac Escalade in the coming months, and it might go on sale in time for the 2022 model year. Expect the supercharger to come with a four-digit price tag. Chevrolet's Tahoe/Suburban and GMC's Yukon/Yukon XL will reportedly be available with a supercharger, too.
