Test Driver Ratings & Comments

Acceleration commentsExceptionally slow off the starting line. At least there's a bit of sauce near the rpm redline. Engine is rather noisy, and not in a good way. Very slow upshifts. A trace of wheelspin when brake-torquing at starting line. Quickest run came with manual-shift mode, although it still automatically shifts before redline. Console lever pulls back for downshifts in performance style although doesn't blip throttle for quick downshifts.
Braking ratingGood
Braking commentsLots of body dive under braking and a bit of wiggling back and forth, but pretty stable overall. Lots of ABS commotion. Pedal effort is moderately firm. First stop was shortest at 119 feet but gradually inceased to 123 feet after seventh stop.
Handling ratingGood
Handling commentsSkid pad: The skid pad shows that the Rio's good handling came through suspension tuning, not its tires, as there isn't much grip. The chassis is not overly responsive to throttle corrections, so it is basically a matter of riding out the understeer. Stability control is not overly intrusive, only cutting the throttle a little bit. Slalom: Pretty darn quick, and several mph faster than previous Rio 5. Car is very composed and never gets out of shape. Excellent suspension tuning and car corners with minimal body roll. Steering very responsive as car turns into corner, though effort level is light and insubstantial. Gearing is such that transmission would usually try to shift into 4th at the last gate, which isn't ideal for quick time. Stability control would occasional apply brakes.
