Next-gen Chevrolet Volt to feature Cadillac ELR’s Regen on Demand system

Article by Christian A., on December 22, 2014

The second-generation of the Chevrolet Volt will feature Regen on Demand, the driver-controlled battery regeneration system found in the Cadillac ELR. This feature allows the driver to employ paddle shifters to decelerate while going downhill or nearing a sharp turn, with the car's momentum converted into electricity for storage in the battery pack.

The capability of the system was demonstrated at General Motors’ proving grounds in Milford, Michigan by no other than GM product development chief Mark Reuss and Volt chief engineer Andrew Farah.

The Volt features two paddles on the back of the steering wheel, which a driver could use to adjust the amount of energy captured by the braking system.

The kinetic energy is then transformed into electricity and stored to the Volt's lithium ion battery pack.

According to Farah, the positioning of the paddle on the steering wheel provides an opportunity for the “people who like to finesse their eco-driving a little bit” to control Regen on Demand directly. In the video, Reuss is using the system with his fingers.

New Chevrolet Volt has an appearance similar to that of an upscale, midsize sport sedan. It also gets a sleek yet performance-oriented stance that properly conveys its capabilities. Chevrolet was able to achieve this by giving the Volt a 105.7-inch (2,685 mm) wheelbase and wheels-out stance as well as wide tracks (61.2 inches or 1556 mm on the front and 62.1 inches or 1,578 mm on the rear and a sculpted belt line.

Bob Boniface, director of design, referred to the Volt as a revolutionary car with a sleek and dynamic design. He described the Volt as technical and refined in execution, featuring a number of interrelating surfaces with clean and crisp edges.

Chevrolet’s design and engineering teams worked with aerodynamicists in GM's wind tunnel to shape the new Volt. As Chevrolet's most aerodynamic vehicle so far, the energy needed to overcome air resistance has been reduced, allowing the Volt to go farther by an estimated eight miles of electric range and 50 miles of extended range. The tapered corners and grille as well as the rounded and flush front fascia help air flow easily around the Volt, thereby reducing aerodynamic drag. The rear end is provided with sharp edges and spoiler that could manage air flow. Turbulence and drag are also reduced by the aggressive rake on the windshield and rear glass.

The element-to-element gap and flush relationships on the new Volt are at par or even better than other vehicles in the segment. Employing similarly grained surfaces and colors, every component in the Volt has high standards of appearance.
