Test Driver Ratings & Comments
Acceleration commentsNothing to be gained by using brake torque or disengaging stability control. There's a slight stumble off the line as the car decides to leave, but from there on out the acceleration is linear and smooth. Some whining and whirring from hybrid powertrain but far less than in Prius.
Braking ratingGood
Braking commentsQuite a lot of forward pitch, but good stopping power with adequate results. Straight, controlled and quiet stops.
Handling ratingAverage
Handling commentsSkid pad: With stability on, throttle reduced to limit performance. With stability control disengaged, the car is well-balanced, tiptoeing on the edge of understeer. Steering feel is remarkably good and feels only a little artificial. Surprising grip. Slalom: Typical reactions with stability control engaged. Conservatively low limits with a beep warning just before automatic brake application. Once stability control is disengaged (it disengages completely), the car is willing to be tossed around, but then it starts to feel heavy and reluctant to respond. Overall, a better performance than expected.
