Cadillac CT6 V-Sport wants to take prisoners with 550-hp 4.2L TT V8

With the refresh of the Cadillac CT6 for 2019, Cadillac welcomes the first CT6 V-Sport as well as a new trim strategy. The changes at the front for the CT6 lineup don't appear substantial viewed head-on, one needs a side view to appreciate the greater three-dimensionality. Thinner headlights and a thinner bumper above a slightly larger lower front intake emphasize the mesh grille, and the vertical LED DRLs make more dramatic statements thanks to those narrower headlights. By angling the main units back toward the rear of the sedan, the CT6 now has a certified, sculpted snout. The rework appears to add substantial overhang, but overall length only increases by a tenth of an inch, to 204.1 inches. What's under the V-Sport's probing hood is just as interesting as the redesign and the sporting thrust: A clean-sheet design of a 4.2-liter DOHC twin-turbo V8. In the V-Sport, the engine produces 550 horsepower and a Bentley-esque 627 pound-feet of torque. As an optional engine elsewhere in the CT6 range, the same engine produces 500 hp and 553 lb-ft. The displacement, specs, plus the fact that "each engine will be hand-built at the Performance Build Center in Bowling Green, Kentucky" indicate this was one of the rumored powerplants for the mid-engine Corvette. The coming sports car was tipped to get a 4.2-liter and 5.5-liter DOHC twin-turbo V8. Based on the position of the turbos in this engine vs. their positions in the previous CAD drawings, we assume the drawings represented the 5.5-liter. (Note: Cadillac said Corvette will not get the new 4.2-liter twin-turbo engine.) The 4.2-liter item features an aluminum block, heads, and pistons, direct injection with a 9.8:1 compression ratio, cylinder deactivation, cylinder oil jets, and a variable-pressure oil system. The twin-scroll turbochargers capable of 20 pounds of boost sit in the 90-degree vee, working alongside twin water-to-air intercoolers, twin throttle bodies, and twin electric wastegates. Cadillac says 90 percent of torque arrives at 2,000 rpm and loiters through 5,200 rpm. Power gets sent through GM's 10L90 ten-speed automatic transmission and on to the standard all-wheel-drive system. Cadillac didn't list 0-to-60-mph times in its press release, but engineers have track-worthy alacrity in mind for the CT6 V-Sport.

Autoblog's ultimate holiday rides

Over the hills and through the woods, it's the time of year when many of us visit family and friends for the holidays. But getting there can be a chore. It's cold and snowy across much of the United States, and even if the climate is favorable, the drive to grandmother's house often is not. Think back to holiday road trips of yore: They probably included crying babies, antsy children, hungover adults and frequent bathrooms stops all around. Now, we're all at different life stages here at Autoblog, and the perfect car for one staffer might be as useful as a team of Budweiser Clydesdales to another. Some of us bounce from family event to family event with children and a labrador in tow, while others prefer a quieter, simpler holiday. But whatever the endeavor, we all need wheels. With that in mind, here is the unofficial Autoblog list of the ultimate cars in which to tackle the holiday season. 2015 Ferrari FF To borrow a chestnut from Top Gear presenter James May, "As you'd expect, I've done this properly." That oddly voluptuous ruby bolide in the photo above? It's a 2015 Ferrari FF – all 652 all-wheel-driven horsepower of it. What makes a Ferrari the ideal for holiday time in PaukertLand? My Midwestern winter breaks are wonderful, but they're typically frenetic and slushy, involving a lot of schlepping from house to house and even city to city, not to mention inevitable last-minute runs for forgotten presents and dinner ingredients. Needless to say, a powerful V12 is a welcome ally for such duties. And this one isn't just a friend when the road is clear. The FF has been gifted Ferrari's novel 4RM AWD system, and despite sitting lower to the ground than, say, an SUV, it's a pretty effective tool for real winter driving, especially when outfitted with a set of snow tires. Unlike other Ferraris, it's also a rather practical thing, with legitimate seating for four adults and 15.9 cubic feet of cargo space – that's precisely as much room as a Mercedes E-Class – and you can fold the rear chairs and cram 28.2 cubes-worth of holiday cheer in the back. Okay, so it's far from cheap and fuel economy isn't that great, but who cares? Just drop a paddle-shifted gear or two, bury the throttle and Repeat The Sounding Joy.

GM intends to offer semi-autonomous vehicles by 2020

Prepare for a few years of technological saber-rattling, as the world's automakers begin pushing to bring self-driving cars to market. Earlier this week, Nissan announced that it aims to offer autonomous vehicles by 2020, while Google, BMW and several other marks are working on similar efforts.
General Motors is doing things differently, though. Rather than push for a fully autonomous car, it's continuing to refine its semi-autonomous Super Cruise, a product that we tested in April 2012 and that will eventually see use on some Cadillacs before trickling down to the rest of the General Motors family. Super Cruise, which is undergoing testing in the Cadillac SRX, doesn't take complete control out of the driver's hands. Rather, under a very specific set of circumstances on the freeway, it will marry the capabilities of things like lane departure warning and adaptive cruise control to allow the driver to take their hands off the wheel. All of which sounds a lot like the system Mercedes-Benz is launching on the 2014 S-Class.
The system is still in development, according to John Capp, GM's director of electrical controls and active safety technology. Now that that the biggest hurdle, steering control, has been cleared, GM's engineers can focus on things like teaching the system to adapt to differing road conditions and visibility levels. As we reported in 2012, Super Cruise is still befuddled in low-visibility situations or when road markings aren't particularly clear.
