DaimlerChrysler ESX3

What is it?
DaimlerChrysler ESX3

What's special about it?
The ESX3 builds on the previous ESX concept vehicles -- the Dodge Intrepid ESX in 1996 and the ESX2 in 1998. Like its forbearers, the ESX3 concept vehicle is an exercise in building a family car with significantly reduced fuel consumption, emissions and costs. It is powered by a hybrid electric powertrain that combines a clean, efficient diesel engine, an electric motor, an advanced lithium-ion battery, and an electro-mechanical automatic (EMAT) transmission. DaimlerChrysler claims the ESX3 can achieve an average fuel economy of 72 mpg. Helping this figure is a low curb weight of only 2,250 pounds. This is achieved in part by a lightweight body constructed from injection-molded thermoplastic and aluminum.

Why should you care?
Vehicle manufacturers continue to research new ways to improve fuel mileage and reduce emissions. The ESX3 contains some interesting technologies, most notably the injection-molded thermoplastic body structure. While the ESX3 itself probably won't ever see production, many of its features could be applied to feature products. For example, the 2001 Jeep Wrangler's hardtop will be made from of thermoplastic to reduce weight.
