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 recalling 524k vehicles over hood latches and toe link nuts

Just hours after confirming to Autoblog its intention to recall 97,540 vehicles in the US (117,651 in North America) for a possible manufacturing defect in the chassis control module of several models, General Motors is issuing two more campaigns that affect another 379,401 units in the US (524,384 in North America).
One campaign covers 290,107 US examples of the 2010-2015 Cadillac SRX and the 2011-2012 Saab 9-4X because the "rear toe link adjuster lock nuts" may be improperly torqued. If not up to spec, the toe adjuster link could separate and allow the wheel to shift while driving, making the handling unstable. GM says that it knows of three crashes and two injuries as a result of this problem. Dealers are inspecting the nuts and installing a new link assembly, if necessary. Autoblog first reported about this potential issue when it showed up on a list of recalls from Transport Canada.
The second recall is for 89,294 examples of the 2013-2015 Chevrolet Spark in the US manufactured from January 17, 2012, through July 29, 2014. According to GM, "corrosion can cause the secondary hood latch striker to stick in the open position." If this happens, and the primary latch also isn't engaged for some reason, the hood could fly open while driving. About 13,000 of these affected Sparks are at dealers and are being held until repaired. The fix requires replacing the hood striker. GM isn't aware of crashes, injuries or fatalities caused by this problem.

2021 Cadillac XT6 adds 2.0-liter turbo and new base trim in second year

The 2021 Cadillac XT6 has been announced, and the three-row crossover is going through a few notable changes in its second model year. There’s a new base trim and base engine, and Cadillac has added tech features to improve the experience. Starting with the new engine: ItÂ’s the 2.0-liter turbocharged four-cylinder that was initially introduced in the XT4 as the base motor. Power output is the same as the compact crossover at 237 horsepower and 258 pound-feet of torque. ItÂ’s paired with the nine-speed automatic transmission and comes with front-wheel drive as standard — all-wheel drive is a $2,000 option. That engine only comes with the new base trim level: Luxury. Every other trim receives the 3.6-liter V6. The new Luxury trim (pictured above) is being added to the lineup as a base model to compliment the Sport and Premium Luxury trims. This will be the cheapest and most basic of the XT6s, but you can still option all-wheel drive. Features include 18-inch wheels, the eight-inch touchscreen infotainment system, black leatherette seats (heated and powered in front), brushed aluminum trim, tri-zone climate control and a number of other smaller extras along with a suite of driver assistance technologies. Cadillac is also adding wireless Apple CarPlay and wireless Android Auto to the lineup as standard equipment — they were standard previously but required the traditional wired connection. ThereÂ’s also a new 20-inch wheel for the Sport model, and three new color options: Dark Moon Blue Metallic, Wilder and Infrared Tintcoat. The XT6 LuxuryÂ’s base price is $48,990, including the destination charge. ThatÂ’s a fair cut below the 2021 Premium Luxury ($53,790) and the Sport ($58,190) trims, but you are losing out on the additional equipment and luxury those trims offer. Cadillac says the updated 2021 XT6 will land in dealerships this fall. Related video:
