Lotus Evora – Safety Systems
In common with the Elise and its derivatives, the Evora's bonded extruded
aluminium chassis tub has incredible inherent strength, particularly in regard to
front and side impacts. Additional torsional strength is given to the whole
structure by the tubular steel seatbelt anchorage frame.
Deformable, sacrificial aluminium front and steel rear subframe modules are
attached to the tub using joints which are designed to minimise damage to the
tub, protecting the main passenger cell in the event of an accident.
Driver and passenger airbags are standard as are pyrotechnic seat belts for
the front two occupants. The airbag on the passenger side is cleverly
engineered to deploy vertically and then be deflected rearwards by the
windscreen, to provide protection.
Anti-lock brakes are standard on all models, as is Lotus Traction Control
(LTC); these systems have been specially developed as a collaboration
between Lotus and Bosch engineers and enable drivers to consistently exploit
the braking and performance capabilities of the Evora, whilst allowing skilled
enthusiasts the freedom to enjoy the full Lotus driving experience.
The Switchable Lotus Traction Control (LTC) system has been developed
simultaneously with the ABS and works through the engine management
system to reduce power to the rear wheels when required to maintain traction.
To maintain front end traction or to reduce understeer, the LTC will gently
reduce engine torque to stabilise the Evora bringing the front wheels back into
line – known as "Understeer Recognition". Unlike many traction control
systems, LTC has been tuned to complement the skills of the driver without
taking over. The Lotus LTC is active above 5 mph (8 km/h) and operates much
more quickly than many brake based systems. The system can be deactivated
completely, giving no traction control intervention.
A Bosch Electronic Differential Lock (EDL) is fitted as standard to the Lotus
Evora. This advanced technology controls the speed of individual rear wheels
through the precise activation of the rear brakes, slowing an excessively
spinning rear wheel to ensure that traction is maintained without causing
detriment to the handling – often the case with a mechanical limited slip
differential.
Hydraulic Brake Assist (HBA) and Electronic Brake Distribution (EBD) are also
fitted as standard. HBA detects an emergency braking situation and increases
brake pressure up to ABS activation threshold which results in shorter
emergency stopping distances.
As with all Lotus cars, the Evora is very driver focussed and therefore all the
electronic intervention systems can be completely overridden by the driver
(apart from the ABS). In standard mode, all the systems above are in
operation; pressing the sport button (Sport Pack option only) sharpens the
throttle response and increases the engine rev limit. The sports mode traction
control is adjusted to give increased slip and yaw angle before intervening,
and also removes the understeer recognition.
