Chevy monitors drivers' biometrics while experiencing new Corvette Stingray

We tell you about what a car is like to drive every day, remarking on throttle response, steering weight and feedback, squat, dive, brake fade and a dozen or more other factors of performance. What we can't tell you, though, is what the car does to us - how its performance impacts us, physically. That's what makes this video series from Chevrolet so darn cool.
The Bow-Tie brand rented out Spring Mountain Motorsports Ranch, got several (very) different individuals together, strapped a bunch of sensors to their bodies to record biometric data ranging from heart rate to respiration to brain activity, and then handed them keys to the new Chevrolet Corvette Stingray. The results are explained in a series of videos, devoted to each driver, showing how different people react to the Corvette's performance.
If, like your author, you're a nerd for medical science, this is going to be a fascinating set of videos. If not, it's still pretty cool to see how the body of someone with racing experience, like Gran Turismo creator Kazunori Yamauchi, reacts to tracking a car like the Corvette Stingray compared to the owner of legendary Detroit barbecue joint, Slows BBQ. Take a look below for all six videos from the series, or hop over to the Corvette Vimeo channel for the interactive experience, where you can see all the different metrics.

GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

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.
