Shelby call it the world's fastest production electric car. But doubt surrounds their other claims — like the 10 minutes it takes to recharge the batteries completely off a 220V plug.

They also reckon their Ultimate Aero EV car will use a twin motor "All-Electric Scalable Powertrain" (AESP) to produce close on 750kW and over 1000Nm. That, the people at Shelby, figure enable the car to hit 100km/h in 2.5 seconds on to a top speed of 332km/h.

Add that to a claimed range of 240 to 320km on a single charge and the vehicle sounds almost too good to be true.

But the claims keep on coming. Shelby's three-speed automatic transmission achieves electronically controlled shift times of 0.24 seconds. And the entire AESP is liquid cooled allowing it to run for extended periods of time at "peak performance" with no overheating issues.

Shelby expect to roll out its first full-scale, pre-production Ultimate Aero EV in the second quarter 2009. Ultimate Aero EV deliveries will start as early as fourth quarter 2009.
