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.

Hotter Cadillac CT4-V prototype spied testing at GM's Proving Grounds

Cadillac already teased us once with the hotter CT4-V and CT5-V at the Belle Isle Grand Prix, but these photos are still the best look yet at what's next for the Cadillac V-Series. The car we're looking at in heavy camouflage here is a high-performance CT4, but we don't really have a name to call it at this point. Cadillac hasn't said, so it could be anything. We'll just refer to it as the faster V, as it's certainly looking a bit more racy than the warmed-over CT4-V already revealed. While the styling isn't drastically different from the CT4-V already out there, the front intake and openings look deeper and more aggressive. The middle, raised section of the hood is a little taller and the whole front-end design looks a lot like the one teased in Belle Isle. This vehicle even appears to have the same mirror design as the faster V. The side sills, quad exhaust tips and wide rear tires lend this prototype an aggressive look, but we did note that it doesn't have the big ducktail spoiler we saw teased previously. Maybe Cadillac is trying to keep a low profile while testing. A keen eye will notice a wild apparatus attached to the front, which would serve as a great jousting pole if you were into that kind of thing. We don't know exactly when Cadillac plans to introduce the faster V machines, but we wouldn't doubt if it happened before the year was out. The ATS-V and CTS-V didn't look wholly different than the pedestrian versions of those cars, and this prototype indicates Caddy may follow a similar pattern this time around. All will be explained from GM soon, but for now, we wait.

New Cadillac ELR ad more educational, less controversial than 'Poolside'

Cadillac's first TV commercial for its ELR plug-in hybrid, Poolside, was a smash hit, in that a lot of people saw and talked about it. The 60-second spot didn't say the car was a plug-in, took potshots at the work ethic of all non-Americans and has raked in over a million views on YouTube (you can add one more here). Caddy's new ELR video will get a lot less media attention, but that's exactly the point. Cadillac claims it was happy with the way actor Neil McDonough strutted his way into the controversial ELR discussion. This time around, though, the coupe gets promoted in a more traditional way: with information about the car and what it can do - you know, drive on electricity, capture braking energy into the battery, go further on gas power when needed, those kinds of things – courtesy of GM's executive chief engineer for electrified vehicles, Pam Fletcher. The tone of the video has not been changed because of the Poolside controversy. David Caldwell, manager of Cadillac communications, tells AutoblogGreen that the new video is not destined for TV and is completely different because it's meant for a different audience. "It doesn't have any direct relation to Poolside," he says. "TV advertising is not necessarily the heart of marketing something like the ELR. Notwithstanding the fact that we had a very thought-provoking ad [laughs]." "We definitely have a need to communicate what the ELR is" - Cadillac's David Caldwell The way you reach out to people via the web is different than the mass-media techniques used in spots like Poolside during big TV events (it aired during the Winter Olympics). The two video spots are different because you need to offer different information in different ways, for example having an ELR website as well as an iPad filled with ELR information at the dealership. For Cadillac, TV is "not going to be the predominant methodology," used to sell the ELR, Caldwell said, "the web is closer to what you need to do to reach people. We definitely have a need to communicate what the ELR is. It's not television advertising at all." Caldwell said a handful of other short videos similar to the new one will go live in the near future, showcasing design and powertrain aspects of the car. Keep an eye out for them – just don't look for them on TV. You can watch the new video below.
