Default GM CEO Akerson Talks 20-Percent Improvement on Volt Electric Range




Quote:
General Motors CEO Dan Akerson’s latest comments have all but confirmed rumors of improved electric range for the next-generation Chevrolet Volt plug-in hybrid. The 2014 Chevrolet Volt achieves an all-electric range of 38 miles according to the EPA, but, in a recent interview with Bloomberg, Akerson said GM hopes to significantly extend the electric range of the next-generation Volt by 20 percent.

Akerson mentioned numbers of up to “50 or 60 miles” in the interview in regards to electric range. He also noted GM is continuing research on battery technology for the next-generation Volt, which should arrive within the next three years.

With rumors of a new three-cylinder, turbocharged engine for the Chevrolet Volt circulating as well, the second-generation car could see improvements in overall range and efficiency as well. The 2014 Chevrolet Volt currently uses a 1.4-liter turbocharged four-cylinder engine as a generator for the batteries and achieves an EPA combined number of 37 mpg with the gasoline engine after the electric range has been depleted. The alleged 1.0-liter turbocharged three-cylinder, which will make its first appearance in the Opel Adam subcompact in Europe and is reportedly slated for Volt duty in the future, could improve the next Volt’s fuel economy numbers as well which would make for a longer total cruising range when electric range and gasoline range are combined.

Since the Chevrolet Volt’s introduction in 2011, it has seen numerous tweaks and updates, including a recent $5000 price cut for the 2014 Volt. Expect to see more of these small updates leading up to the completely redesigned Volt in 2016, when we will see if Akerson’s claims come true or not.

Then there should be some new patents coming out on this, unless 20% range increase = 20% decrease in vehicle engine/battery/electronics lifespan.

Give me a CUV not 20% more range. Give me another seat, not 20% more range... anyway geez it already covers like 75% of peoples daily travel on electricity. You increase the range and you get diminishing returns in terms of additional daily travel it would cover b/c they will never get range to drive 200-1000 miles in a PHEV and should not.

I'd rather have a Prius.

My gripe with the Volt is not the range but the lack of a 3rd back seat and horrible back seat head room. The Prius and Leaf have better utilization of space.

This. And the poor visibility.

The extra range is a decent improvement, but I agree. The lack of a 3rd back seat prevents it from being an option for me.

Default 2016 Chevrolet Volt Plug-In Hybrid



Quote:
According to General Motors, the 2016 Volt is “the most customer-inspired car to be launched in recent history.” While there’s basically no way to verify that claim, it’s no secret that Chevrolet kept in close contact with owners of the current Volt during its production run. When asked how to improve the upcoming 2016 Volt, the owners responded with an overwhelmingly universal reply: extend the EV range. While this was hardly a revelation, customers’ second request—that Chevy make the car more fun to drive—took the maker by surprise. And so Chevrolet tried to do both.
Power Trio

Called the Voltec Extended-Range Electric Vehicle (EREV) propulsion system by GM, the Volt’s powertrain ties together a battery pack, the drive unit, and a range-extending engine, as well as myriad control electronics. Volt chief engineer Andrew Farah describes the process of engineering the setup as an “exercise in energy management.”



To provide the powertrain with a healthy source of current, GM revised the battery-cell chemistry, increasing the storage capacity by 20 percent while simultaneously reducing the total number of cells from 288 to 192 and shedding about 22 pounds of weight. The battery is now capable of storing 18.4 kWh (versus 17.1 kWh previously), and its discharge rate has also increased slightly to 120 kW from 110 kW, which helps improve performance. Still assembled into a T-shaped pack, the cells are now positioned lower in the unit, which contributes to a lower center of gravity for the car. The battery advancements enable the new Volt’s claimed 50-mile EV range, a significant improvement over the current car’s 35-mile rating. Overall range while using the onboard gasoline engine is projected to be 400 miles, and GM is quoting an anticipated MPGe figure of 102.



While horsepower remains the same at 149, torque increases by 21 lb-ft to 294. Designed with improved noise, vibration, and harshness characteristics in mind (reduced NVH was third on the customer wish list), the new motor-generators are closer in size in contrast to the previous car’s large-motor/small-motor configuration. We’re told that the use of rare-earth elements has been almost eliminated in the motors’ construction—one motor uses none of the materials, the other only a very small amount—and that this saves costs and reduces reliance on outside suppliers. GM says the motors are capable of operating either in tandem or individually in the interest of optimizing performance and efficiency. Power flow is managed by the Traction Power Inverter Module (TPIM), which has been integrated into the drive unit to reduce mass and size and to improve powertrain efficiency. GM says the two-motor setup is 12-percent more efficient than before and that nearly every component in the system is new or overhauled.

The motors operate together more frequently than before, sharing the load in more driving scenarios and during both EV and extended-range situations. A single motor often can supply power for low-speed situations—such as urban driving—but both motors can be engaged for heavy-load or higher-speed demands such as merging or passing at highway speeds. Using both also helps acceleration, with Chevrolet claiming that the 2016 Volt dashes to 30 mph in 2.6 seconds and to 60 mph in 8.4 seconds, 0.5- and 0.4-second better than the best times we achieved in the outgoing car.
New Engine, Four Holes

The third member of the Volt’s efficient propulsion trio is the range-extending internal-combustion four-cylinder engine*. Note the description—rarely will a member of the Volt team refer to it simply as “the engine.” Replacing the previous 1.4-liter four-cylinder unit is a naturally aspirated 1.5-liter four producing 101 horsepower. The first domestic application of GM’s new Ecotec engine family, the 1.5-liter counts direct injection, a variable-displacement oil pump, cooled exhaust-gas recirculation, and wideband cam phasers among its bag of efficiency tricks. Despite running a comparatively high 12.5:1 compression ratio, this Volt will happily sip regular gas, whereas the previous Volt demanded premium. Motivated by the gasoline engine alone, the 2016 Volt, GM says, is capable of returning 41 mpg on the EPA’s combined cycle.



Four driving modes are available: Normal, Sport (more aggressive accelerator and power-delivery characteristics), Mountain (the engine and battery combine power to traverse steep grades), and Hold (forces the Volt into extended-range operation for longer-distance highway driving and to maintain battery charge). Those bent on getting back a maximum return on their momentum investment will be thrilled with the new Regen on Demand feature. Activated by a steering-wheel-mounted paddle, it increases the energy-regeneration function, recapturing excess energy on deceleration that otherwise requires an application of the brake pedal.

I think GM did a good job on updating the volt. At least a car seat can be stuck in the middle now. It still doesn't meet the requirements I have for my next car, but it really is a significant improvement in many ways. I do hope they did not regress on battery lifetime. GM was way better about that than their competitors previously. I wonder if they will change their wording to emulate Nissan now or keep their better warranty.
