Battery storage capacity increase and cell chemistry changes enable improved range
The all-electric vehicle range of the 2013 Chevrolet Volt will be 38 miles on a single charge, providing owners with a three-mile EV range increase from the 2012 model. The miles per gallon equivalent (MPGe) will increase from 94 miles to 98 miles and the total range, including extended range operation, will be 380 miles.
Based on real-world experience by Volt owners since the vehicle launched in late 2010, engineers made minor changes to the material composition of the battery cell chemistry, resulting in improved performance and durability. Manganese spinel chemistry remains the foundation for the Volt’s battery system, but the amount of each material has been slightly modified to provide better life performance.
“The best way to explain what we’ve done at the cell level is to compare it to a cake batter recipe. Sometimes if you use more sugar and less vanilla you get a better tasting cake. We’ve done some work at the cell level to modify the ‘ingredients’ to make a better end result,” said Bill Wallace, GM director of Global Battery Systems Engineering. “This attention to detail will allow our customers to experience more pure EV range, which is the true benefit of owning a Volt.”
In addition, the total storage capacity of the Volt battery has been increased from 16 kWh of energy to 16.5 kWh, and engineers have expanded the state-of-charge window to use 10.8 kWh of the total battery energy – up from 10.3 kWh used in the 2012 model. The battery system maintains a buffer to ensure battery life, but that buffer has been reduced.
The improved EV range capability will result in slight increases to the Volt’s charge times. A full recharge using a 120V could take 10.5 hours and 4.25 hours using a 240V charging unit.
Cells with improved chemistry have accumulated 150,000 test miles to date. The tests have revealed less battery degradation, the ability to withstand temperatures as low as -30 degrees Celsius and less impact by energy throughput.
For the first 38 miles, the Volt can drive gas and tailpipe-emissions free using a full charge of electricity stored in its 16.5-kWh lithium-ion battery. When the Volt’s battery runs low, a gas-powered engine/generator seamlessly operates to extend the driving range another 344 miles on a full tank. Volt owners have travelled more than 65 million miles since the vehicle launched late 2010. Roughly two-thirds of those miles were powered by grid electricity.

CHEVROLET VOLT: THE INNOVATIVE ANTIDOTE TO PAIN AT THE PUMP
The Chevrolet Volt has established an entirely new segment in the global automotive market. It is a five-door, four-passenger car designed to provide the fuel-saving and emissions-reducing benefits of an electric vehicle without the range limitations associated with all-electric vehicles.
With numerous awards that include prestigious North American Car of the Year and European Car of the Year honors – as well as a loyal and passionate customer base – the innovative Volt is bringing new customers into Chevrolet dealerships.
For 2013, Volt offers an e-AT-PZEV specification that earns the Volt a coveted “green sticker” for single-occupancy HOV lane access in California and New York. Volt also adds a Hold mode that allows owners to direct when the Volt uses its gas generator. This feature helps save money because owners who mix city and highway driving can save the battery charge for city travel, where the Volt’s EV mode operates most efficiently.
Other updates for 2013 include a body-color roof and decklid, available lane departure warning system and forward collision alert crash-avoidance technologies, as well as GPS-enabled navigation capabilities to Chevy’s MyLink infotainment system.
A new exterior color, Silver Topaz Metallic, and new interior color, Pebble Beige, also join the Volt lineup.
The Volt is available throughout the U.S., with additional exports to Europe, China and Canada.
The Volt is built at General Motors’ Detroit-Hamtramck assembly plant, home to the largest photovoltaic solar array in southeast Michigan. The facility can use the 516 kilowatts of solar energy generated by the 264,000-square-foot array (24,526 sq. m) to charge up to 150 Volts or help power the plant.
Volt propulsion system
The heart of the Chevrolet Volt is its Voltec propulsion system, which combines pure electric drive and an efficient, range-extending engine, giving the Volt up to 382 total miles (615 km) of range.
The Volt’s long-life battery consists of a 5.5-foot (1.6 m), 435-pound (198.1 kg) T-shaped, 16 kWh lithium-ion battery pack. It supplies energy to an advanced, 111-kW (149-hp) electric drive unit to propel the vehicle. Using only the energy stored in the battery, the Volt delivers an EPA-estimated 38 miles (61 km) of fuel- and tailpipe emissions-free electric driving, depending on terrain, driving techniques and temperature.
The Volt battery is covered by an eight-year/100,000-mile warranty. When the battery energy is depleted, the Volt seamlessly transitions to extended-range mode. Power is inverted from a technically advanced, 1.4L 84-hp (63-kW) gasoline-powered onboard engine to the electric drive unit to provide up to 344 (553 km) additional miles of range.
Charging the Volt’s battery is simple and intuitive, and can be done with a 120V conventional household electrical outlet, or a dedicated 240V charging station. The vehicle is completely rechargeable in about four hours using a 240V outlet and 10 to 16 hours in a 120V outlet (depending on charging level and outside temperature).
Once the vehicle is plugged in, owners can schedule either immediate or delayed charges, even coordinating charging according to departure time or when electricity rates are lower. Owners also can manage and monitor the Volt remotely via computer on MyVolt.com; or via a smartphone through RemoteLink, an exclusive smartphone application powered by OnStar.
Volt design and exterior features
Working closely with aerodynamicists in GM’s wind tunnel to shape the Volt, design and engineering teams developed the most aerodynamic vehicle in Chevrolet’s history. By reducing the energy needed to overcome air resistance, Volt aerodynamicists contributed an estimated eight miles (5 km) of electric range, and 50 miles (80 km) of extended range.
The Volt’s rounded and flush front fascia, tapered corners and grille enable air to move easily around the car to reduce drag. In the rear, sharp edges and a carefully designed spoiler control air flow. A n aggressive rake on the windshield and back glass also help reduce turbulence and drag.
Additional exterior features include:

Volt chassis and suspension
The Volt’s MacPherson strut-type front suspension, sophisticated compound crank rear axle and quick-reacting, rack-mounted electric power steering system with ZF steering gear have been tuned to deliver a smooth, refined ride with responsive handling and a solid, on-center feel.
A low center of gravity combines with the wide track and long wheelbase for balanced performance. Front and rear hydraulic ride bushings help eliminate road harshness.
An electro-hydraulic regenerative brake system captures energy up to 0.2g for transfer back to the battery. The friction braking system features large rotors with a special finishing process that protects against corrosion and promotes longer life.
The Volt rides on lightweight aluminum wheels that weigh only 17.8 pounds (8.1 kg) each, compared to 24.2 pounds (11 kg) for typical 17-inch wheels. They’re wrapped in Goodyear Fuel Max all-season, low-rolling resistance tires optimized for electric vehicle range, noise, feel and performance.
Volt safety and crash-avoidance features
The Volt helps protect occupants before, during and after a crash. C rash-avoidance features include standard anti-lock brakes with traction control, StabiliTrak electronic stability control and advanced, LED daytime running lamps that make the Volt more visible to other motorists and pedestrians.
Occupant protection continues with a strong structure, and the Chevrolet Volt’s body-frame-integral structure strategically blends advanced steels to help ensure crashworthiness and stiffness. Nearly 80 percent of the Volt’s overall structure consists of high-strength, advanced high-strength or ultra high-strength steel.
Because the Volt operates so quietly in all-electric mode, a driver-activated feature sounds a noise to alert pedestrians, particularly those with visual impairments, in an intersection. The alert was developed in conjunction with the American Federation of the Blind.
Additional safety features include:
Eight standard air bags, including dual-stage driver and passenger air bags; front driver and passenger knee air bags to help mitigate lower leg injuries; roof rail side-curtain air bags that extend over both seating rows for side-impact and rollover protection; and seat-mounted thorax and pelvic side air bags
