Toyota has several fingers in a few electric pies. There's the electric car it's working on in-house, in conjunction with Panasonic, using proprietary technology. Then there are two mash-up prototypes that Tesla is building for Toyota, which according to Bloomberg include an electric RAV4 and Lexus RX. According to the report, the crossovers were chosen because they're the best fit for the weight of Tesla's battery pack, which uses 6,831 lithium-ion batteries.
Even though the Elon Musk says he expects, "range and acceleration exceeding that of other announced electric vehicles of this class," we wonder if he's including a crossover like the BYD e6. The electric SUV from China is currently testing in the Shenzhen taxi fleet and claimed to have a range of 186 miles. If that's his target, then the numbers would exceed the figures Toyota has for the joint project, with an ideal cost of "about $40,000 with 150 miles (240 kilometers) of driving range per charge."
Tesla's electrified RAV4 and Lexus RX are predicted to be delivered to Toyota this month, so expect a barrage of news to be forthcoming.
