No traction control here, but the wheezy engine doesn't produce enough oomph to need it in the dry. Brake torque works best, then the car produces a cute chirp as the tires latch on. Sadly, there isn't enough motor to make this car qualify as merely slow. Using manual upshifting near the redline is good for another tenth, however. Watch out!
The pedal feels firm enough and the Yaris feels stable during full-ABS stops. The high 120s seems a bit long for such a light car, but then it has skinny low-rolling-resistance tires for fuel economy. At least it's relatively consistent and predictable.
Slalom: Tuned conservatively to operate safely without stability control. Steering response and overall handling is respectable and well mannered, but not sporting. Gets the job done. Skid pad: Safely understeers its way to a 0.76g lateral acceleration number. Not much adjustability here. Plenty of body roll.
