1. Stowed position
2. Deployed position
Airbrake - AERO button OFF
The Airbrake remains stowed at speeds below
93 mph (150 km/h).
At speeds above 93 mph (150 km/h) the Airbrake
deploys, moving dynamically dependent on the
vehicle's requirements. This enhances vehicle's
high speed stability with increased aerodynamic
drag. The Airbrake may actively deploy at speeds
below 93 mph (150 km/h) during sudden braking
or when high vertical or longitudinal G forces are
measured.
Airbrake - AERO button ON
The Airbrake is deployed and moves dynamically,
dependent on the vehicle's requirements. This
enhances vehicle stability with increased
aerodynamic drag. The Airbrake will raise at any
vehicle speed.
1. Press the ACTIVE button to switch on the
Active Dynamics Panel.
2. Press the AERO button and the Airbrake
deploys.
NOTE: The Airbrake may automatically
lower to reduce aerodynamic drag in
favour of straight line speed if the
vehicle is travelling in a straight line at
full throttle.
