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.

It leverages the latest technology to balance efficiency, performance and refinement in the upcoming, top-of-the-range CT6 luxury performance sedan. The all-new Cadillac 3.0L Twin Turbo is designed to achieve new thresholds of refinement and specific output for the brand's new prestige luxury sedan, which makes its world premiere March 31, at the New York International Auto Show. Production begins late this year at General Motors' Detroit-Hamtramck Assembly Plant.

2020 Cadillac CT4 spied completely undisguised for the first time

A few weeks ago, Cadillac gave us our first look at its new small luxury sports sedan in the form of the CT4-V. This was a bit unusual considering the company hadn't shown us the regular one yet, and the reveal is still off in the not-too-distant future. But we were lucky enough to catch a normal 2020 Cadillac CT4 parked at a local gas station completely and totally undisguised. Based on what we know about other recent Cadillacs and their trim and design, this CT4 is probably a Luxury or Premium Luxury trim, since it has plenty of bright chrome and red taillights instead of dark gray ones. The differences from the CT4-V are subtle. The mesh grilles of the V are swapped for a main grille studded with small Cadillac badge shapes and the lower grille has simple slats. The little air intakes by the lower sections of the running lights are smaller than the ones on the V. This car also lacks the V's side skirts and wider canards on the edges of the front bumper. There doesn't appear to be a rear spoiler either. While we've had a good look at the exterior of the CT4, we'll have to wait until the car's full reveal later this year to know what's under the skin. We do know that it will continue to use the Alpha platform shared with the CT5, Camaro and the old ATS and CTS. We suspect the base engine will be the same 2.0-liter turbocharged inline-4 from the CT5, which makes 237 horsepower and 258 pound-feet of torque. Since the CT4-V uses a turbo 4-cylinder that makes 320 horsepower and 369 horsepower, there might not be a V6 option for the regular CT4. The CT5's twin-turbo 3.0-liter V6 makes more power and torque, so that's out, and the old ATS's naturally aspirated V6 made 335 horsepower and 285 pound-feet of torque, which would be uncomfortably close the CT4-V's specs. But we could see a V6 of some sort in an even more potent V iteration of the CT4 later.

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.
