Toyota and Tesla have officially announced that the electric prototypes being developed by the California startup are based on the RAV4 crossover, and the two companies hope to have a production version ready by 2012.
Toyota press release says ...

With an aim to market the EV in the United States in 2012, prototypes will be made combining the Toyota RAV4 model with a Tesla electric powertrain.
No information on range or price. I guess late 2012 - so about 30 months away.
