With six airbags, anti-lock brakes, and stability control standard across the lineup, the Cooper is a safe small car.
Though the NHTSA and IIHS haven't yet tested the 2011 MINI Cooper, the 2010 results from the NHTSA scored five-star rollover ratings.
The Convertible hasn't been tested, but offers standard pop-up roll bars and automatic airbag deployment in the event of a rollover. Hill-start assist helps get things going on steep stretches, minimizing the chance of rolling into the car behind.
Available safety options inclue Xenon headlamps, parking sensors, and run-flat tires (standard on the Cooper S).
