We have all seen electric utility vehicles but never perhaps considered that electric propulsion would dominate the future of full sized family transport. Our view of what a car is may well change markedly over the next 18 months. The Chevy Volt is on track to be delivered at the end of 2010 and in doing so may mark a defining change to the automotive world of gas combustion engine cars we have come to rely on.

The Challenges faced in transport are many but basically there needed to be a wholesale change in the generation, delivery, storage, usage, safety and environmental effects of our use of energy to propel ourselves across this planet. When assessing all these areas to stick to electrical energy makes undeniable sense. As once it is generated electricity can be transmitted, stored and used with relative safety and almost zero harmful emissions. Not only that but the infrastructure and technology already exist to make use of electrical energy. So why has this change taken place before?

Answer, such a major shift in technology and behaviour can only be done when the time is right. The current economic crisis allied with the move to environmental responsibility as well as the need to be more self-sufficient in energy makes this the right time to change.

So the introduction of the Volt is striking the right note with the consumer. To overcome the preconceived idea that battery operated cars run down and leave you stranded the design is termed ‘Extended-Range Electric Vehicle’. It has a rechargeable battery plus an on board gas powered generator for the times when you exceed its basic range. The basic range is targeted at 40 miles with a full charge and that is said to cover the basic daily commute of 75% of American commuters. If you go beyond this or get stuck in traffic then there are no worries. The gas can recharge the batteries or power the car with seamless effort and outstanding efficiency.

Efficiency is the key design concept. In order to make the first 40 miles the design will tolerate no area of inefficiency. So aerodynamics, drive train drag, tire friction and onboard utilities have to be honed for efficiency. Allied to this an energy recovery system will top up the battery when braking putting the used energy ‘back in the tank’. Zero gasoline with zero emissions is the target.
