Earlier today, I spent some time discussing the development of the Chevrolet Volt extended-range electric vehicle at the Management Briefing Seminars in Traverse City, Mich. My team has put a lot of effort into creating a beautifully designed, fun-to-drive vehicle – inside and out. The beauty of the Volt’s design is much more than just surface deep, the interior and exterior design is an important element of the vehicles overall mission to be one of Chevrolet’s most energy efficient vehicles - ever.
Why are our efforts in the design studio so important? When you’re driving down the road, it takes energy to slice through the air that is pushing against the car. That force is known as drag and it can account for up to 20 percent of the energy consumed in an average vehicle. One of the challenges as a designer is to reduce aero drag, while still creating a design that is compelling. We do that by experimenting with different angles and curves and then testing the car in our wind tunnel, which blasts air at the car to measure the effect of drag.
Aerodynamics is extremely important for an electric vehicle like the Volt, which is designed to drive up to 40 miles using only electricity to power the car. By minimizing aero drag, we can maximize the range of the battery. So, it shouldn’t come as any surprise that my exterior design team spent countless hours in the wind tunnel with our aerodynamicist to refine the Volt’s exterior. We believe this was time well spent - when you’re trying to extend gas-free driving of the vehicle, you’ll take all the efficiency you can get.
(Take a look at this video, which you can also see in our video sidebar, inside the wind tunnel.)
We believe the Chevrolet Volt’s exterior design is an attractive balance between aerodynamic performance and styling. Included below is a detailed image of the driver-side front quarter of the vehicle. If you look closely, you can see the rounded and flushed front fascia, tapered corners and closed grille are aesthetically beautiful and functional, enabling air to move easily around the car. In the end, we believe the vehicle is both aesthetically pleasing and extremely efficient.
The pictures below also showcase many of the exciting styling elements and design themes carried over from the concept vehicle to the production model design. Let us know what you think of the photos by leaving a comment.
Today at the Management Briefing Seminars in Traverse City, Mich., Bob Boniface, director of design for Chevrolet Volt at General Motors, showcased how aerodynamics is shaping the design of the Chevrolet Volt. According to Boniface, \
