Chevrolet Volt's aero efficiency
- Teaser image shows wind tunnel work
- Aerodynamics now 30% more efficient
- Testing to begin in 2008, on sale in 2010?
This teaser image shows the latest incarnation of the Chevrolet Volt electric car.
The Volt is powered by a battery which can be charged by a tiny on-board engine if necessary.
Although the picture gives little away, it shows a significantly more aerodynamic car than the original concept vehicle.
Work in GM's wind tunnel in Michigan, USA, is reported to have reduced the Volt's drag by 30%, making it around 7% more energy-efficient.
In addition, engineers have had to balance the need for aerodynamic efficiency against the requirement to achieve enough under-body airflow to cool the battery pack.
Road testing of the Volt is set to begin in 2008, with a production version of the car likely by 2010.
Latest figures suggest it can run for 40 miles on battery power alone, which would be sufficient to power two-thirds of commutes in the USA.
