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.

Teaching autonomous vehicles to drive like (some) humans

While I love driving, I can't wait for fully autonomous vehicles. I have no doubt they'll reduce car accidents, 94 percent of which are caused by human error, leading to more than 37,000 road deaths in the U.S. last year. And if it means I can fly home at night in winter and get safely shuttled to my house an hour-plus away — and not have to endure a typical white-knuckle drive in the dark with torrential rain and blinding spray from 18-wheelers on Interstate 84 — sign me up. Autonomous technology will also take some of the stress, tedium and fatigue out of long highway drives, as I recently discovered while testing Cadillac Super Cruise. AVs are also supposed to eventually help increase traffic flow and reduce gridlock. But according to a recent Automotive News article, as the first wave of AVs are being tested on public roads, they're having the opposite effect. Part of the problem is they drive too cautiously and are programmed to strictly follow the written rules of the road rather than going with the flow of traffic. "Humans violate the rules in a safe and principled way, and the reality is that autonomous vehicles in the future may have to do the same thing if they don't want to be the source of bottlenecks," Karl Iagnemma, CEO of self-driving technology developer NuTonomy, told Automotive News. "You put a car on the road which may be driving by the letter of the law, but compared to the surrounding road users, it's acting very conservatively." I get it that, like teen drivers, AVs need a ramp up period to learn the unwritten rules of the road and that a skeptical public has to be convinced of the technology's safety. But this is where I become less of a champion on AVs, since where I live in the Pacific Northwest we already have more than our share of overly cautious human drivers. Since moving here 12 years ago, I've found it's an interesting paradox that a region famous for its strong coffee, where you'd think most drivers would be jacked up on caffeine, is also the home to annoyingly measured motorists. As an auto-journo colleague living in Seattle so aptly put it: "People in the Pacific Northwest drive as if they have nowhere to go." If you drive like me and always have somewhere to go — and usually are in a hurry to get there — it's absolutely maddening.

Forget everything you know about Cadillac V

Cadillac rolled out the CT4-V and CT5-V performance sedans to a rather confused group of journalists last night. What are these cars? Only 355 horsepower in the CTS-V replacement? And just 320 horsepower for the ATS-V successor? Surely, there's something out of place — you can get up to speed with all the details here. Cadillac understood our confusion and explained what was going on rather quickly. The explanation means you have to forget everything you know about what "V" means for a Cadillac, though. Any Cadillac with the singular "V" badge on it previously has denoted the absolute top-tier of performance for that particular model. The CTS-V had the Corvette Z06 engine in it and made 640 horsepower. The ATS-V had a boosted 3.6-liter V6 good for a raucous 464 horsepower. They were equivalent to BMW M, Mercedes-AMG or an Audi RS. We're not talking about the lesser M or AMG models, either. No, the last Cadillac Vs were meant to compete with cars like the C63 or M3, the top-tier of performance in those brands' lineups. This is where you're going to have to start re-learning, because that's no longer the case for a Cadillac with a V badge gracing the rear end. What Cadillac has essentially done is demote what V means, with the intention of offering "something else" above it. With this new strategy, we'd equate a Cadillac V to something like an AMG 43, M340i, or Audi with an S badge on it. Cadillac has even come out with a car similar to this strategy before in the V-Sport. That didn't confuse everybody, though, because the name was different, and the strategy was clear. Now, Cadillac V is just a small stepping stone to these mysterious high performance cars still to come. We asked for any information concerning these future track-ready, fire-breathing monsters, but mum is the word for now. The naming strategy for something above a V is uncharted territory, and it'll also force everyone to learn what the top of the Cadillac lineup is all over again.

Think future vehicles like an XT5-V, XT4-V and others like that. Now that V doesn't mean a Nurburgring-conquering 500+ horsepower luxury muscle car, it makes it far easier for Cadillac to get V badges on everything. Obviously, GM isn't the first to think of this strategy.
