The 2013 Chevrolet Corvette hasn't been crash-tested by either the NHTSA (National Highway Traffic Safety Administration) or the IIHS (Insurance Institute for Highway Safety)--but then, neither have most other high-end sports cars.
All Corvettes come with anti-lock brakes, Active Handling stability control and traction control, dual front and side airbags, immensely capable brakes, and agile handling--all the better to help avoid an accident in the first place.
One issue we've found with the Corvette, though not everyone will mind, is visibility. Rearward visibility through the hatch and forward visibility over the long hood and flared fenders can make it hard to place the car in close quarters or see nearby obstacles. Another potential drawback for some is the lack of side-curtain airbags.
