2017 Chevy Bolt EV arrives in late 2016 with 200-mile range

For those keeping track, the production 2017 Chevy Bolt that was just revealed at CES in Las Vegas is, well, pretty much just what we were expecting. As promised, GM claims the EV crossover-ish hatch will have a 200-mile range, and be "affordable." While pricing hasn't been announced, we've posited in the past that "affordable" is code for around $30,000 after incentives. The Bolt will use a couple of features, both novel and expected, to enhance range. The EV is expected to use information on the owner's driving history, the weather outside, the terrain, and even the time of day to help manage and predict range. The nav system will optimize routes to conserve range, if needed, and show nearby charging stations. That should ease, if not eliminate, range anxiety. Another range-conserving feature is a low-draw Bluetooth system. Speaking of charging stations, there's no word so far about how long it'll take to recharge a Bolt, or the capacity of the battery pack. Inside, the large center-mounted MyLink screen measures a full 10.2 inches, and provides a display for the wide-angle rear camera with a birds-eye view capability. OnStar provides 4G LTE and a wifi hotspot to occupants, and the sorts of efficiency and driving habit apps you'd expect will be available. It seems like remote start and cabin preconditioning will be standard. Interestingly, the Bolt will feature "Gamification" features intended to promote efficient driving by pitting Bolt drivers against each other for green driving awards or rankings. Details on are sparse on this feature, but then again, information on the Bolt in general is a little sparse right now. If you want to know things like detailed specs, the specifics of chassis componentry, or even trims and options, you'll have to wait. Check out our first quick spin of a prototype Bolt in Las Vegas for a preview of what GM's EV is like on the road. Chevrolet Introduces 2017 Bolt EV First long-range, affordable EV with customer-focused connectivity LAS VEGAS – Chevrolet is introducing the 2017 Bolt EV at the Consumer Electronics Show, fulfilling its promise to offer a long-range, affordable electric vehicle for the masses. The Bolt EV, which will go into production by the end of 2016, will offer more than 200 miles of range on a full charge. It also features advanced connectivity technologies designed to enhance and personalize the driving experience.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.

2023 Chevrolet Silverado HD reportedly getting mammoth torque

Chevrolet just gave the light-duty Silverado a significant round of updates. It hasn't detailed the changes it has in store for the heavy-duty model yet, but a recent report claims the truck will arrive with significant engine upgrades. Without citing sources, website TFL Truck reported that the current pickup's 6.6-liter Duramax turbodiesel V8 will return in the updated model. Its displacement won't increase, but its output will reportedly grow to 505 horsepower and a mammoth 1,085 pound-feet of torque. To put those figures into perspective, the 6.6-liter makes 445 horsepower and 910 pound-feet of twist in the 2022 Silverado HD; GMC's Sierra HD is available with it as well. Bumping the Duramax's output is a way to keep up with the competition. Arch nemesis Ford offers buyers who have extremely heavy things to tow 475 horsepower and 1,050 pound-feet of torque from a 6.7-liter turbodiesel V8. Over at Ram, the most powerful engine available in a heavy-duty truck posts numbers of 420 and 1,075, respectively. If the report is accurate, Chevrolet will enviably take the horsepower and the torque crowns in the segment. What remains to be seen is what effect the increases will have on the Silverado's towing capacity. As of writing, it's capable of towing up to 36,000 pounds (approximately 15 times the weight of a 2021 Mazda MX-5 Miata). Moving out of the engine bay, the 2023 Silverado HD will receive an updated exterior design that will again help differentiate it from the smaller, light-duty model. We're expecting the next round of updates will also bring new tech features, and it's reasonable to assume that the trim structure will evolve; Chevrolet might notably shift the HD in a more outdoorsy direction to satisfy a growing demand for off-road-focused trucks in the United States. None of this is official; Chevrolet is keeping its lips sealed about the updated Silverado HD. Full details will likely emerge in the coming months, and sales are tentatively scheduled to start in time for the 2023 model year.
