If I am stuck in 30 miles of bumper to bumper traffic, how many miles of that would be pure EV if the speed never reached over 20 - 25 mph ?
Hi Cd,
The Prius has approximately 2 hp-hr battery capacity. If you start your crawl with the battery "full" and discharge down til the engine starts to recharge it you can use about 1.2 hp-hr. The Prius uses about 2 or 3 hp to maintain 25 mph. So the most optimistic estimate is at a constant speed you could go about 15 miles. But if it's stop & go, the accelerations and braking will reduce that considerably. Accessories too. High or low temperatures reduce battery capacity.
