The World’S Most Efficient Electric Car

Gordon Murray's, T.27, (the world’s most efficient electric car)
. . . Yamaha's, bringing it to production.

8.8 feet long and 4.8 feet wide, seating for 2.
. . . A steel cell with crush zones and
. . . anti-intrusion bars surrounding the passenger compartment.
. . . The powertrain is also installed within structure.

Powered by a compact, 8.8 kilowatt-hour battery pack,
. . . yet delivers up to 100 miles per charge.
The motor weighs just 13 kg [29 lbs],
. . . the gearbox just 11 kg [24 lbs].
These are components that you can pick up with one hand.

This is a new generation of EVCM, that integrates:
. . . . . . torque arbitration,
. . . . . . temperature control and
. . . . . . voltage management to allow better decision making.
It optimizes the driver’s torque request based on a broad range of parameters,
. . . including battery charge and temperature and the grip available at the tires.
By integrating these decisions, we can provide more with less, to improve:
. . . . . . driving experience and
. . . . . . the range while reducing the
. . . . . . size, weight and cost of the power electronics and battery pack.
