ALTe already has Gen 1 proof-of-concept systems running in a Crown Vic taxi equipped with a 20 kWh Li-ion battery pack. In the Crown Victoria, the proof of concept powertrain conversion systems improve fuel economy from 80%-200% from the base 4.6L Gen 2 system in a rolling chassis. Click to enlarge.

ICEVs have been around for a while, and although they’ve had the time to perfect their manufacturing process and we’ve seen increased pressure on the importance of fuel economy and emissions, the thermal efficiency of the average light vehicle engine remains between 20-35%, and we’re not seeing much improvement beyond this.

One wonders if the recent headway at MIT in building lithium ion cells using ?virus? based technology will actually achieve any economy in production. If no one wants your car (because people think it sucks), then no one will buy it, regardless of how good the fuel economy may or may not be. Interesting in any case.
