is not only one of the most
exciting cars on the road,
it is also one of the cleanest.
This is achieved using a range of
technologies, including twin
catalytic converters and stereo
Lambda or oxygen sensor circuits.
One pair of sensors is used to
measure the oxygen levels in each
of the twin exhaust tracts. An

entirely from stainless steel.
All lightweight materials are easily
recyclable, while the variety of
synthetic components has been
reduced. Recycled plastics are
used in all areas of the car where
they meet our exacting technical

Water-based paints are used
throughout the car, thus reducing
dependence on chemical solvents
in both production and subsequent
servicing. All areas of the vehicle
are free from asbestos, CFCs,
and components manufactured
using CFCs. The result is a car in
which environmental protection
is an integral part of the design.
