Detroit Electric SP:01 delayed again.

The revival of Detroit Electric and the imminent arrival of its first vehicle, the SP:01 sports car, have us hooked, not because the EV is the most innovative design around (based on the Lotus Exige, it's strikingly similar to Tesla's discontinued Lotus-based Roadster), but because it promises to be yet another American-built high-performance EV with some unique twists. We like the fact that customers can opt for a four- or five-speed manual transmission (particularly unusual in an EV), or use the car to power a building in the case of a power outage. Unfortunately, we'll have to wait a bit longer before the SP:01 hits the road, because Detroit Electric has yet to finalize a lease or purchase agreement of its chosen production facility in Plymouth, Michigan, The Detroit News reports.

Detroit Electric has been trying to hammer out an agreement, but the negotiations for the Plymouth facility are producing enough uncertainty that Detroit Electric's North American President Don Graundstadt says the automaker-to-be is negotiating with other parties.

Previous plans for SP:01 production called for its manufacture to begin by this month, but plans change, and production will be pushed back. There is no mention of when the electric sports car will become a 2,500-unit-per-year reality, but rather ominously, The Detroit News notes that "the immediate fate of the automaker should be known in the next couple of weeks."
