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.

Drivers buy new $300K McLaren 720S, 2019 Chevy Corvette, and wreck 'em

Two high-powered, high-priced sports cars, wrecked in their infancies. No doubt they were fun while they lasted. In Great Falls, Va., a tony suburb of Washington, D.C., that hugs the Potomac River, someone was out enjoying driving the McLaren 720S they had purchased only the day before on a leafy, two-lane road. Then, horror: In an instant, the car hit a tree, mangled and destroyed "because of speed," according to the Fairfax County Police Department. Purchased Friday. Totaled Saturday. This McLaren 720S, costing around $300,000, was destroyed today in Great Falls because of speed. The driver was taken to the hospital with thankfully only non-life threatening injuries. A reminder to slow down, or it could cost you. pic.twitter.com/XhC3LKRY1t — Fairfax County Police (@FairfaxCountyPD) July 14, 2018 Then on salvage auction site Copart, a brand-new orange 2019 Chevrolet Corvette Grand Sport lies in a warehouse in Lincoln, Neb., its front left corner crushed, wheel askew. It had just 15 miles on the odometer. We know nothing of the backstory, except for the obvious front-end damage and secondary damage to the undercarriage. The rear end and 6.2-liter V8 engine, which makes 460 horsepower and 465 pound-feet of torque, look OK. The most current bid as this was published was just north of $9,000. It's tempting in both cases to assign the blame to over-eager drivers who weren't quite yet able to corral all that power. In the case of the McLaren, the supercar makes 710 horsepower and 568 pound-feet of torque from its quad-cam, twin-turbo 4.0-liter V8. It goes from 0-62 miles per hour in 2.9 seconds and boasts a top speed of 212 mph. We're not saying the unidentified driver was a newbie, but this car is definitely not for newbies. Police write that the incident is "A reminder to slow down, or it could cost you." As in, $300,000. Or at least the depreciation for driving it off the lot. Related Video:

2022 Chevy Tahoe, Suburban and GMC Yukon get updated transmission

General Motors' full-sized SUVs have slipped in one more change before the year turns. GM Authority reports that the 2022 Chevrolet Tahoe and Suburban, and the 2022 GMC Yukon and Yukon XL equipped with gas V8 engines, will pick up a revised ten-speed automatic transmission. The new unit carries RPO code MHS, and Chevrolet communications rep Catherine Scales told GMA the updated gearbox "allows our manufacturing and dealer teams to more easily align the specific calibration needed for the transmission and can enable OTA updates in the future." It seems GM wants to make it easier to update the transmission's tuning and calibration in the future with the automaker's networked Vehicle Intelligence Platform/Global B electronic architecture. The 10-speed auto comes bolted to the 5.3-liter V8 and the 6.2-liter V8. The 3.0-liter inline-six Duramax diesel continues with the 10-speed automatic already in use. To recap the other changes for the full-sizers, we'll start with the 2022 Tahoe and Suburban, which get a new 12.3-inch digital instrument display to replace the former 8-inch unit and physical gauges. Navigation will be standard equipment displayed on the 10.2-inch infotainment touchscreen on all trims barring the base LS. Lane-keeping assist and parking sensors are also now standard, while reverse automatic braking is added to the Enhanced Display and Alert package on the top trims. Finally, the 6.2-liter V8 option is expanded to the Z71, RST and Premier trim levels, but it requires selecting one or more packages on the Z71 and RST. Moving onto the 2022 Yukon, availability of the 6.2-liter V8 expands to the AT4 trim, and the big V8 comes with a shiny pair of exhaust finishers. Redwood Metallic paint joins the exterior color palette, more wheel options are on offer, and illuminated sill plates can gussy up the rocker panels . An Enhanced Trailering Technology Package adds 13 cameras with the option for an interior accessory camera for those with enclosed haulers. On the safety side, expect reverse automatic braking to join the list of available driver assistance features. Inside, the Yukon welcomes the 12.3-inch digital cluster, the Yukon Denali welcomes the power sliding console as a standard feature instead of a $350 option.  Related Video:
