The IDEA is fitted with a pedal unit with a plastic mount that houses the brake and clutch pedals. The clutch pedal is plastic.The brake pedal (steel), includes a device that allows the pedal to collapse in the case of impact to limit intrusion into the passenger compartment and injury to the lower limbs.The chosen solution (pedal unit separate from the power unit) permits the installation of a larger brake servo (10').The accelerator pedal (plastic) is fitted separately on a special mount and the accelerator control is electronic (Drive by Wire system) on all engine versions.The accelerator pedal is fitted with two built-in potentiometers (a main one and a safety back-up). These send pedal movements to the control unit, which opens the throttle by the required amount.A pedal/brake ratio of 3.6 combined with aa 15'/16' pump ensures reduced pedal travel and allows brake servo size to be exploited to the full. Braking is also smoother and more gradual.Pedal arrangement has been optimised to make the pedals more user-friendly by considering ideal ankle angle and pedal spacing parameters. On versions with a robotised gearbox and automatic transmission, the pedal unit does not include a clutch release pedal because the function is performed automatically.
