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.

GM cutting vehicle trim options to save money for electrification

Information continues to filter out about GM's plans based on comments the automaker made during its Capital Markets Day event in February. GM President Mark Reuss said the company's push to save money by rationalizing the number of build combinations will continue in 2020, carrying on the work done in 2019. As GM Authority covers, last year, the carmaker cut 3,500 components across model lines, a 12% drop in the number of parts it needed to stock in its plants. Reuss used the next-generation Chevolet Equinox and GMC Terrain as examples for more cost efficiencies, saying build possibilities — which include international markets and their options — will be cut by more than 50%, and use more shared parts. "We will reduce total trim levels on Equinox and Terrain from eight to six," Reuss said, "reduce engine variants from 11 to 5, reduce build combinations from more than 200 to less than 100 per program, and see significant cost savings of an already paid-for architecture that took the mass out, helping us self-fund electrification programs." GM will plow a large amount of the money it saves into its ambitious EV program. In 2017, the automaker said it intends to have 20 electric vehicles on the market by the end of 2023, some of which could be shared between brands. An automotive analyst at Seeking Alpha and a piece in Automobile attempted to put specifics to what we should expect. As Automobile points out, the first two EVs in the 20-car program are already on sale, being the Ariv Meld and Ariv Merge eBikes available in Belgium and The Netherlands. We've seen the Cruise Origin autonomous rideshare taxi, although we don't know when it will hit the road. The next three, which we should see in the metal shortly, are two Cadillac EVs and the GMC Hummer EV pickup. The Cadillac pair are expected to be sized like the XT4 and XT5, and along with the Hummer, should hit the market starting in late 2021.

2020 Cadillac CT4-V First Drive | The Cadillac of compact Cadillacs

With the launch of the 2020 Cadillac CT4, GM is pushing back into the smallest luxury sedan segment that in recent years has almost exclusively featured entries from Germany. We're pleased to see it return, and importantly, that it definitely came back prepared. The CT4’s key differentiator is its platform. Unlike the bulk of entry-level luxury sedans currently on the market, the Cadillac rides on a rear-wheel-drive platform. All-wheel drive is available throughout the lineup for those who need (or just want) four-season flexibility, but itÂ’s meant to be a convenience feature rather than a performance upgrade — the same is not true of its front-wheel-drive competitors. The CT4 ostensibly replaces the discontinued ATS, but reality is a bit murkier than that. Stop us if youÂ’ve heard this before, but the Cadillac CT4 is not entirely size-appropriate for the class. While the CT4 is aimed at the subcompact luxury sedan segment (and the CT5 at the compact), itÂ’s dimensionally a bit closer to the likes of the Mercedes C-Class than it is the A-Class. This gives Caddy a bit of an advantage, but itÂ’s nothing we havenÂ’t seen from GMÂ’s luxury arm before. Cadillac has chosen instead to target the segment based on price, which is a win for consumers in a way, as you can get a little bit more bang for your buck if theyÂ’re willing to take a chance on the underdog. Cadillac is offering its new small sedan in three states of tune. The base (“Luxury”) model boasts a 2.0-liter engine good for 237 horsepower and 258 pound-feet of torque. The Premium Luxury and CT4-V models get the 2.7-liter — which is still a four-cylinder — that makes 310 hp and 350 lb-ft of torque in its base tune and 325 hp and 380 lb-ft in the CT4-V. All three variants make use of GMÂ’s active fuel management tech which allows them to run on just two cylinders to conserve fuel while cruising. Yes, you read that correctly. The CT4-V boasts just 325 hp, which may seem like a pittance considering the outrageously powerful V models of CadillacÂ’s past, but GMÂ’s luxury arm has decided to re-jigger its performance hierarchy by eliminating “V-Sport” entirely, shifting “V” down to fill that role, and introducing a series of new range-topping performance models dubbed “Blackwing.” In that context, the CT4-V may seem like an also-ran, but consider the company it keeps.
