From TreeHugger:
Ruf Automobile GmbH, a German automotive company that has been tuning Porsches for a long time, will make an electric version of the Porsche 911 called the eRUF Model A.
Under the hood, a 150kW (201hp) brushless three phase A/C electric motor that can generate an impressive 480 lb.-ft. of torque and a lithium-ion iron-phosphate battery pack made of 96 160Ah Axeon cells and a sophisticated monitoring system to make sure it doesn't overheat.
But the battery pack could be replaced as new technology comes out. In its press release, RUF says: "The generation of batteries available from Axeon represents by no means the end of the developmental curve. Current performance improvements in battery technology indicate that end of this improvement spiral is nowhere near.
