2011 Lexus CT 200h

Lexus says the point of the Drive Mode Select is to allow "highly distinct characters" for more driver choice. Waxing poetic, the company calls the CT 200h's "hybrid attitude" the Darker Side of Green.
The four driving modes are Normal, Eco, EV and Sport. The first three are intended to emphasize "more relaxed driving" including smooth acceleration and minimal interior noise. The EV mode is for speeds under 25 mph and for up to a mile, on electric motor power unaided by the engine. Eco mode reduces throttle response to "aggressive" use of the accelerator and modifies the air-conditioning for the best fuel economy.
As its name suggests, Sport mode is the most dynamic choice, with faster response to driver input, higher rpm and more direct steering feedback. Operation of Lexus' vehicle stability control and traction control systems is "less intrusive" for more driving fun, the automaker says.
The Normal, EV and Eco modes use a "hybrid blue" backlighting on the instrument panel and show a hybrid power indicator. In Sport mode, the backlighting changes to red and the hybrid power indicator is swapped out for a tachometer.
