The latest EPRI* Journal (PDF) has an interesting article about the future of hybrid vehicles and the benefits of new plug-in technology, which has led to the ungainly name of PHEV (Plug-in Hybrid Electric Vehicles). New York, Kansas City and LA are apparently testing a Dodge Sprinter PHEV and seeing some pretty amazing results.
At current U.S. energy prices — that is with the cost of gasoline at $3 per gallon and the national average cost of electricity at 8.5c per kilowatthour — a PHEV runs on an equivalent of 75c per gallon. And given that half the cars on U.S. roads are driven 25 miles a day or less, a plug-in with even a 20-mile-range battery could reduce petroleum fuel consumption by about 60%.
A PHEV passenger car is said to be able to recharge in three to four hours on a regular 120V (well, regular for the US) outlet, and ideally would be charged at the end of the day when “40% of the generating capacity in the United States sits idle or operates at reduced load overnight.”
I hate to ask but will the diesel version of the Sprinter (based on the Mercedes engine) have a PHEV option? The electric-city/biodiesel-highway vehicle seems like the perfect high-performance low-cost solution to help drive the US economy and military away from the impending petroleum disaster.

Here is one of the graphs from the report, which actually mentions increasing security risks due to petroleum-based energy:
