GM's redesigned full-size 2021 SUVs face delay over coronavirus

As General Motors works to conserve cash for the coronavirus pandemic, the automaker reportedly told suppliers that it is postponing development of several future vehicles. The situation may cause GM to delay the launch of the 2021 Cadillac Escalade, GMC Yukon, Chevrolet Tahoe and Chevrolet Suburban SUVs, which had been planned to roll out in April. The original launch plan for the redesigned full-size SUVs, which are some of the most profitable vehicles produced by GM, had called for production of the current models to end at its plant in Arlington, Texas, this week. After a retooling process, the redesigned SUVs were slated to begin production late in the month of April. In an email to suppliers viewed by Reuters and confirmed as authentic by GM, the automaker also said it was suspending development work on six future vehicle programs, including updates of the Chevrolet Equinox, GMC Terrain, Cadillac XT4, Bolt EV, Chevrolet Silverado and GMC Sierra. GM said preproduction work on those programs would be pushed back to calendar year 2021, with most of the updated vehicles scheduled to be launched as 2022 models. According to the Detroit News, work has also been paused on the Chevy Camaro and a future version of the Corvette that has yet to be unveiled and wasn't planned for production during the 2020 calendar year. Last week, the automaker told employees and suppliers it was delaying work on some future vehicles while pushing ahead with near-term models such as its redesigned full-size SUVs and the GMC Hummer EV, Cadillac Lyriq, Chevrolet Bolt EUV and Cruise Origin, as well as its new Ultium battery system. A GM spokesman who spoke with Reuters reiterated on Monday what the automaker had said last week — that the situation with its U.S. plants was "fluid" and that the automaker would "continue to evaluate" whether and when to reopen those plants on a week-by-week basis, with "employee safety" guiding that decision. GM said previously that it was closing most of its U.S. plants indefinitely. In its Monday email, GM asked suppliers to stop work on all pre-production tooling and pre-production parts manufacturing, but also not to dispose of any tooling or materials. GM told Reuters it had solicited volunteers from its workforce to finish the build-out of the current SUVs on a single shift in Arlington.

NHTSA could add 1M cars to GM recall

The Detroit Free Press is reporting that the National Highway Traffic Safety Administration may expand a recall campaign for faulty brake lamps. The agency is currently looking into complaints that certain 2004-2011 Chevrolet Malibu models as well as some 2007-2009 Saturn Aura sedans may have brake lights that do not illuminate when the driver presses the pedal. Alternatively, the lamps may also illuminate without input from the driver. General Motors recalled 8,000 Pontiac G6 models from the 2005 model year for the same problem, and NHTSA is currently investigating whether to add 550,000 more G6 models built between 2005 and 2009 to the list for the same issue.
In addition, investigators are currently examining 97 complaints from Malibu and Aura owners with the same trouble. If NHTSA adds those models to the recall campaign, more than one million units could be covered. GM, meanwhile, says there have been no accidents or injuries as a result of the problem.

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
