In top-spec form the E-4 Coupe offers 553
lb-ft (750Nm) of torque.
Delta Motorsport, the Silverstone-based automotive engineering
firm, have been developing the E-4 Coupe since 2007.
Last year they entered the car in the Automotive X-PRIZE Competition,
and this year they've brought the design a step closer to full
The Delta E-4 Coupe was designed and engineered from the ground
up to be an electric powered car - unlike many other electric
powered vehicles which are based on platforms originally fitted
with internal combustion engines.
Because the car was solely designed for electric power, the
engineers were able to optimize the car's weight, layout and
structure, without having to make compromises.
The Delta E-4 Coupe features a bonded carbon-fiber one-piece
chassis/body which is both light and strong.
The batteries are all placed low down in the vehicle to keep
the center of gravity as low as possible. The batteries make
up a significant proportion of the vehicle's overall weight,
so finding the best place to put them was an important engineering
The Delta E-4 Coupe can be fitted with a range of different
electric motors and battery packs. The most expensive and powerful
setup uses four individual motors, one for each wheel, and offers
553 lb-ft (750Nm) of torque. That means the 0-60 mph sprint
is over after just 4 seconds, and the car is capable of hitting
150 mph. The lower-spec options include just two motors, one
for each rear wheel, and a less powerful battery pack.
The Delta E-4's range is also dependent on which powertrain
is fitted. The most potent system has a 200 mile range, while
the cheaper option runs out at 140 miles.
