GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

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.

Cadillac CT5 spied with quad exhaust, could signal a hotter version is coming

The 2020 Cadillac CT5 just broke cover at the NY Auto Show this year, but one of our spy shooters caught one decked out in camouflage looking a bit different than the versions we've already seen. Instead of the dual exhaust on both the turbocharged four-cylinder and twin-turbo V6, this one has a quad exhaust outlet. We'll note that the placement of the quad outlets is one and the same with the two larger outlets on the CT5 already revealed. Also, the rest of the car looks relatively ho-hum. It has the wheels from the CT5 Sport trim, and the front end appears to most closely represent the Luxury trim. Some of the coverings appear to be opened up on that front end, possibly in an attempt to increase airflow. The most obvious change of them all is the quad exhaust, though, which brings us back to a conversation we had with a Cadillac representative at the car's initial media launch. As we were standing around gawking at the new CT5 in Sport trim, a brand representative told us all the "Sport" models (four-cylinders and V6s) would be getting quad exhaust, while the "Luxury" trims would get dual exhaust. We pointed at the CT5 Sport right in front of us and noted that it just had a dual exhaust setup. This ended up causing more confusion, as the Cadillac representative was adamant that they had seen the CT5 Sport with quad exhaust. When all was said and done, there wasn't exactly a clear explanation given for what was up with this mysterious CT5 model with quad exhaust, so we left it at that. We can guess, though. Perhaps the Cadillac rep had seen a Sport model with quad exhaust, but it was a future "V-Sport" variant we weren't allowed to know of yet. Cadillac hasn't revealed its future plans for the CT5 fully, but it did hint that at least one performance variant would be on the way. This camo'd up car here does not look anything like a full-on V model, but it could be the beginnings of a slightly more powerful version of the sport sedan. The 3.0-liter twin-turbo V6 makes 335 horsepower and 400 pound-feet of torque. Of course, there's always room for more power in this class, and a V-Sport model would slot in nicely to the new sedan's range. Keep in mind this all remains speculative in nature. However, our curious conversation with Cadillac combined with these spy shots signal that something could be afoot.
