Lotus Dynamic Performance Management (Lotus DPM)
Lotus DPM is an Electronic Stability Control system utilising hard-
ware provided by BOSCH to Lotus’ specification.
This is incorporated into the software programme integrated
within the engine management and ABS electronic control units
(ECUs).
This feature enhances vehicle stability in extreme manoeuvres
typified by accident avoidance attempts or misjudged cornering
demands. Current vehicle behaviour is constantly monitored, and
compared with a determination of driver intent as indicated by
data gathered from the driving controls. When vehicle stability
is at risk, the ABS is utilised to apply a measured braking force
to individual wheels and modulate the fuel injector delivery and
throttle opening as necessary in order to help the driver maintain
control of the vehicle.
This feature can improve vehicle stability in some extreme
conditions of use, especially where variable or differential side/
side surface grip prevails, or when maximum vehicle perform-
ance is being exploited. See also ‘EDL’ (page 88).
If the Lotus DPM tell tale in the instrument panel is seen to
flicker, this is an indication that the system has been triggered

been reached and driving style should be modified accordingly.
WARNING
The enhanced vehicle control that this feature provides should
not induce any relaxation of caution or vigilance by the driver.
Physical limits of cornering and braking still apply, and exces-
sive speed may result in loss of control and an accident. The
driver is at all times responsible for the judgement of appro-
priate speed.
