2016 Chevy Volt will have more EV range, bigger battery

Meet the new Volt, not the same as the old Volt. That appears to be the story when General Motors introduces the 2016 Chevy Volt at the Detroit Auto Show in January. Today we're getting some more details on the guts of the new plug-in hybrid, and it turns out they're going to be much improved from the current Volt, which first went on sale at the end of 2010. Sure, the first-gen Volt did get some improvements along the way (a slightly larger battery pack, lane departure warnings) but the new Volt – which will go on sale in the second half of 2015 – marks the first time GM has been able to return to the drawing board and really make the improvements that its customers want. That's how Larry Nitz, GM's executive director of vehicle electrification explained it to AutoblogGreen today when explaining the all-new Voltec extended range electric vehicle (EREV) powertrain. "In the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability." – Larry Nitz Nitz said that the new Volt will be better in almost every sense: a bigger battery, longer EV-only range, 20 percent better acceleration in the low speed range and higher overall efficiency. This is due, in part, to the Volt's two motors being able to both act as generators and power the car. As we noted this morning, the 2016 Volt will use a larger, 1.5-liter four-cylinder engine, a version of which is already used in the Chinese-market Cruze. Nitz said that this has a number of benefits, including more power and quieter operation. "Some people would say, why did you make [the first-gen engine] so big. I would say, why did you make it so small?" he said. "It works good, our customers love it, but the reality is that if you go a little bit off and use the car a little harder, you can get the engine to need to operate at a higher speed. In an EV, that's quite noticeable. So, what we did in the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability and what it has marginally enabled is not only is it more efficient but it's also quieter." Nitz wouldn't talk about how the new powertrain might affect the two other products that use the Volt's underpinnings – the Cadillac ELR and the Opel Ampera – but if you've got a quieter option, we assume that's something ELR drivers would enjoy. But that's a story for another day.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Leveling kit now available for Chevy Colorado, but not yet for GMC Canyon

In various bits of news this year concerning the Chevrolet Colorado and GMC Canyon pickups, we kept hearing about a front leveling kit. GM Authority found a few details in early order guides in January. In February, the kit came up in relation to the Canyon's AT4 Off-Road Performance Package, and again with AEV's upgraded Colorado Bison. After three months of waiting, GMA has more info. The kit eliminates the trucks' raked stance by raising the front by one inch, using an electro-coated upper spacer and a polyurethane lower spacer in order to maintain the proper suspension geometry. Installation is a bolt-on job with low-profile nuts, but the task will require a spring compressor. Fitted properly, the kit doesn't void GM's new vehicle warranty on the Colorado. Why do we only mention the Colorado? Because for some reason, the kit isn't available for the Canyon yet as a standalone component; the GMC stays raked without one of the aforementioned option packages. For Chevy, the leveling kit is compatible with any trim in four-wheel drive except the ZR2. It cannot be installed on two-wheel-drive trucks, nor any truck wearing wheels that are 20 inches or above. The kit is available now, ordered through any Chevy dealer for $150. There is a treat in store for GMC buyers, though, but it requires spending a lot more money. GM Authority discovered that the 2021 Yukon will offer the brand's first illuminated emblem. Priced at $475 as a dealer-installed option, a backlit glow will show off the GMC logo in the grille. The brand makes the logo in red and black, it's thought the red logo will get the nod, at least at first. Only the front logo earns the spotlight, not the one on the tailgate. GMA says the tchotchke will be available on all four trims when the new full-size crossover goes on sale in a few months.
