Drive Mode Select Switch

Supplementing the NORMAL drive mode of new Lexus, three 'ondemand' drive modes may be selected via the Drive Mode Select switch, adapting the Lexus CT 200h to either a Dynamic or Relaxing driving mood, while further improving either performance and dynamic ability, or driving efficiency, fuel economy and emissions.

EV, ECO and NORMAL drive modes place the emphasis on a Relaxing driving mood, with particular attention paid to ride comfort, smooth acceleration and the minimisation of NVH within the body, chassis and powertrain.

From start-up and at speeds of less than 45km/h the CT 200h can automatically operate in EV mode, driving under electric motor power alone. The driver may also select EV mode manually. This unique driving mode is not available to drivers of mild hybrid vehicles, requiring the full hybrid technology of Lexus Hybrid Drive.

With vehicle range dictated by battery charge, the EV drive mode allows for relaxing urban driving with minimal noise, and zero CO2, NOX and particulate emissions, for up to two kilometres. Because the petrol engine is switched off throughout its operation, the EV drive mode contributes to a significant reduction in the new Lexus' overall fuel consumption.

In ECO mode, throttle response to aggressive accelerator pedal inputs is reduced and air-conditioning control optimized for improved fuel economy. Depending on driving conditions, the ECO mode can help customers adopt a relaxed driving style, and can achieve a perceptible reduction in fuel consumption.

Specifically tuned to deliver greater electric motor power, SPORT mode focuses on a Dynamic driving mood, maximising the new CT 200h's performance and agility.

The hybrid system PCU boosts supply voltage by 150V to a maximum 650V, increasing overall powertrain output. Engine revs are held higher, and throttle and Electric Power Steering (EPS) settings are modified to give a faster response to driver inputs.

In addition, SPORT mode provides less intrusive operation of the Vehicle Stability Control (VSC) and Traction Control (TRC) systems, allowing drivers to fully exploit the new Lexus full hybrid's extended dynamic abilities.

The highly distinct character of both the Lexus CT 200h's Dynamic and Relaxing driving moods is further reinforced through changes to the driver's instruments synchronised to driving mode selection. Backlit in hybrid blue for the EV, ECO and normal drive modes, the instrument panel illumination, Drive Mode Select switch and a spotlight in the centre cluster automatically alter to red when the SPORT mode is selected. Simultaneously, the hybrid power indicator function alters to that of tachometer.
