Today Gordon Murray Design Limited and
Toray Industries Inc announce a prototype electric sports car named
TEEWAVE AR.1. The AR.1 had an
internal GMD code number of ' T.32' and the car is the result of a
commission from Toray for Gordon Murray Design to design, tool and build
a fully functioning prototype vehicle which utilises many of Toray's
advanced automotive materials in order to achieve Toray's basic concept
of an attractive vehicle for everyone.
The 2-seater sports car is designed to
use the Toray carbon fibre component system with a process time of less
than 10 minutes. A carbon monocoque, one of the key technologies of
TEEWAVE, can be applied to all types of vehicle other than the 2-seater
sports car.
The entire programme from concept
discussions to running vehicle took just 9 months and was delivered on
target, both in terms of cost and final handover. The power train in the
vehicle are the base components used in one of the commercial electric
vehicles currently available, but the unique electrical architecture and
control units were developed by Gordon Murray Design.
A carbon front crash structure was
designed and developed for the car. A Full vehicle Euro Ncap O.D.B
test was simulated in addition to a rigid barrier dynamic impact. A
correlation process was conducted on the front crash structure for both
half energy and full energy using physical tests. Quasi -static bend
and torsion analysis was also conducted.
The AR.1 has a remarkably low weight of
just 850kg (including the 240kg battery) putting the car firmly in Lotus
Elise territory and some 400kg lighter than a Tesla. The ultimate
performance is limited by an output figure of 47kw but a torque of 180
Nm available from a standing start results in lively acceleration.
A great deal of attention has been
given to the low weight, low centre of gravity and suspension geometry
which has resulted in an excellent ride and handling balance.
