All a little to radical, how about Dodge ESX3's mild hybrid electric powertrain combines a clean, efficient diesel engine, electric motor and state-of-the-art lithium-ion battery to achieve an average 72 miles per gallon fuel efficiency (petrol equivalent).
The lightweight body makes use of another DaimlerChrysler innovation - injection-molded thermoplastic technology that achieves significant improvements in weight and cost. The ESX3 weighs in at just 1020 kg (2,250 pounds) while meeting all federal safety standards and providing the roominess and comfort of today's family sedan. As a bonus, the entire vehicle is more than 80 per cent recyclable.
Improving fuel efficiency is key to the future of American prosperity
