T.27 EV
Car is just as ugly as the T.25

Gordon Murray is one of the most famed car designers and engineers in the world and his most famous creation in the eyes of many enthusiasts is the McLaren F1 that was the world's fastest production car for years. Murray has since turned his attention to creating cars that are green and powered by batteries rather than fuel swilling cars capable of 200 mph top speeds.

Murray has unveiled a new electric minicar called the T.27. The EV is hailed as the world's most efficient EV and is just as ungainly as its predecessor, the T.25. Murray worked with powertrain partner Zytek Automotive to bring the new T-27 to market and the new car uses a lightweight and fully integrated electric motor, control system, and battery for the best efficiency.

The T.27’s specs include a 25 kW electric motor and a 12 kWh lithium-ion battery pack. The car is very small with a length of 98 inches, width of 51 inches, and height of 63 inches. The car weighs in a 1,500 pounds with the battery and has a 70-inch wheelbase. The range on a single charge is expected to be 100 miles.

Murray said, "The Technology Strategy Board have been incredibly supportive of the T.27 programme and together we are working to keep this in the United Kingdom.  It is a great opportunity to work with Zytek Automotive and our other partners on this very exciting programme.  We always strive to lead the way in automotive design and our current goal is to maximise efficiency of electric vehicles."

Insideline reports that the car seats three and is slated to debut on November 5 at the RAC Future Car Challenge. The car was constructed with financial backing of the British Government Technology Strategy Board.

Pricing hasn’t been announced, but the T.25 sold for a relatively cheap $9,000.

Okay, so, this might be a dumb question, but with these specs...
The T.27’s specs include a 25 kW electric motor and a 12 kWh lithium-ion battery pack.
...doesn't that mean you have a grand total of 1/2 hour battery life? That's just some quick napkin math, but....

Pedal to the metal--you are right. The designers apparently expect stop and go driving and probably brake and downhill regeneration of the battery.

Also, you're highly unlikely to be able to use all 12 kWh from a Li-ion battery. If you do, after a year the battery will probably only hold 6 kWh or less.

To prevent a Li-ion battery's max capacity from diminishing with charge/discharge cycles, you have to limit the cycles so they don't come close to 0% or 100%. So more likely you can only use something like 8 kWh out of the 12 kWh total capacity.

Pretty sure that's the peak power output.

Only if you use all 25kW for the 1/2 hour, and don't recover any energy from braking. Even then, you'd probably get less than a 1/2 hour since you can't draw all the energy from the batteries, and high draw actually lowers the capacity compared to low draw. You might be able to do that, but it's a pretty unlikely scenario.

Try grabbing a non-governed gas car and floor it until your speed tops out, and you'll see some pretty crappy mileage too.
