Chevrolet’s Volt extended-range electric car, due here in 2012 as a Holden, will ride on specially-developed fuel-efficient Goodyear tyres
And its Bose sound system is configured to use as little energy as possible, further boosting fuel economy and range.
Chevy says low rolling resistance Goodyear Assurance Fuel Max tyres give the Volt an extra 1.6 kilometres of electric-only range, boosting it to just on 66km.
The Volt’s Bose sound system is 30 percent smaller, 40 percent lighter, and uses 50 percent less energy than conventional Bose set-ups.
Chevy says that in “certain listening and driving conditions” that energy saving results in increased all-electric drive capability equivalent to removing up to 23kg of mass from the Volt.
The Volt uses electricity stored in a lithium-ion battery pack for trips of up to 64km. Then a small engine-generator creates additional electricity to extend the range by several hundred additional kilometres until the driver can plug in to the electricity grid to recharge the battery
