efforts are likely to reduce during the break-in process.
After 600 miles (1,000 km) have been covered, full throttle
and/or maximum rpm may be used for short periods, but not
until the first 'After Sales' service has been carried out should
full car performance be exploited.
Note that various operating parameters are continuously
monitored and recorded in the engine electronic controller. This
data may be downloaded by Lotus dealers on demand to assist
fault diagnosis and identify vehicle misuse.
Tires: New tires also require a short 'break-in' period before
providing optimum grip.

Engine Special Features

The engine of the Elise is designated VVTL-i for 'Variable
Valve Timing and Lift - intelligent'. Using microprocessor control,
the inlet camshaft timing is advanced or retarded according to
immediate operating conditions, and the lift of both inlet and
exhaust valves is increased at high engine speed. This technol-
ogy is used to provide high power output whilst retaining good
low speed response.
