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.

Well, if you want to delve into the aerodynamics of it... There are two major components to drag (these are not the only ones, they're just the major ones):

Surface drag - basically friction between the skin of the car and the fluid (air in this case) running past it.

Form drag - energy expended by the car to displace the fluid, and as the fluid returns after the car has passed. (On ships, this wasted energy shows up as ship's wake directly behind it.)

At high velocities like what a plane travels at, the form drag dominates. So the teardrop shape helps a lot for planes.

A low velocities, as long as your shape is relatively smooth (no big, flat appendages sticking out), the surface drag dominates. In particular, cutting off the tail end abruptly can actually result in lower drag. Doing so increases your form drag, but the loss of all the surface area associated with the long teardrop tail means a larger reduction in surface drag. Your net drag is thus reduced.
