Chevy Volt, Nissan Leaf go nearly the same all-electric miles a year

Range anxiety? What range anxiety? The concept is a foreign one to those driving Chevrolet Volt extended-range plug-ins, and as a result, that vehicle's all-electric driving miles are actually pretty close to that of the all-electric Nissan Leaf. Such were the findings of a study conducted by the Idaho National Laboratory (INL), which tracked about 8,700 cars during a three-year period, including a bunch of Volts, Leafs and Smart ED electric vehicles. In short, even though the Volt's all-electric range of about 38 miles is less than half that of the Leaf's, the Volts' collective all-electric driving was just six percent lower than the Leaf's (the next-generation Volt will be even more electro-generous, with a 50-mile range). The logic makes sense considering typical US driving habits, in which a vast majority of people commute less than 35 miles a day. Additionally, Volt drivers obviously have no fear of running out of electricity, so they were far more likely to max out on that range than some Leaf drivers. Overall, the average Leaf is driven about 15 percent less than the national average of about 11,300 miles a year for all vehicles, while Volts are driven about eight percent more. Of all those Volt miles, about 81 percent were in all-electric mode. Additionally, Volt drivers recharged about 1.5 times a day, while Leaf drivers recharged about once a day, and about 85 percent of that charging was at home. As for non-home charging, about 20 percent of the vehicles accounted for 75 percent of the station use, so folks are definitely creatures of habit. Check out the INL's 22-page report here for more interesting details.

Chevy bringing Spark RS Concept to SEMA

Well, the SEMA mess has well and truly begun. Every year, an increasing number of automakers flock to the Las Vegas auto show, bringing accessories and concept vehicles that are both awesome as well as occasionally questionable. Chevy will bring an RS concept of the new Spark to SEMA, signaling that its styling package will be applied to the brand's smallest vehicle in the near future. We can expect the usual stuff in a production Spark RS – larger wheels, a slightly sportier cabin, a more aggressive body kit, and a small drop in ride height – but for the concept, Chevy wasn't restrained by things like budget. The front splitter, and sill extensions, foglight surrounds, and rear bumper insert are all finished in carbon fiber. The 17-inch alloys are apparently inspired by the Corvette Z06's Z07 package, while the Dark Liquid Switchblade Silver paint is broken up only by a driver's-side stripe. The company is also using SEMA to show its new Red Line accessories, features both concept and production parts for the Trax, Camaro, Malibu, Colorado, and Sierra. Every vehicle gets Enhanced Silver Metallic paint, a charcoal finish on the roof, satin graphite/red graphics, black/red badge kits, and aside from the Colorado, tinted lamps. Individual mods for the Trax include relatively simple tweaks, including new 18-inch wheels, blacked-out bowtie badges, a lowered ride height, and custom badging. It's a similar story on the Malibu, except that its 19-inch wheels are a smidge larger, and its lowered ride height is the result of a concept kit. The first concept based on the new Camaro opts for 20-inch wheels, while adding a few more performance items. The ride height has been lowered, there's a new air intake system, and an upgraded brake package. Chevy has also replaced the front upper and lower grilles inserts with red accents. On the pickup side of the coin, the Colorado gets 18-inch wheels, new intake and exhaust systems, Goodyear Wrangler Fortitude tires, and flared wheelarches. The Silverado gets similar intake and exhaust upgrades, as well as the largest wheels of them all, with 22s at all four corners. The full-size truck also gets a Brembo brake package, while every vehicle, aside from the Camaro, gets Thule roof-mounted accessories. You can check out all six concepts in the gallery above, and then be sure to keep an eye open for live images from the floor of the 2015 SEMA show, slated to open next month.

GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video
