Although the 2010 Dodge Challenger hasn't been crash-tested by both major U.S. agencies, it's fared very well in one set of tests; the federal government (NHTSA) gave the Challenger five stars in all frontal and side tests.
Nearly all the expected safety equipment is now included on the Challenger. Electronic stability control, anti-lock brakes, front side airbags, and side curtain bags are standard across the model line. The top-of-the-line 2010 Dodge Challenger SRT8 heaps on additional safety features, which Motor Trend lists as "Hill Start Assist, which helps manual transmission cars launch more securely on inclines," and upgraded Brembo brakes. Cars.com reports that the Dodge Challenger "SRT8 has traction and stability control to avoid spinning the tires and [keep] you headed in the right direction," a valuable feature in a car as prone to wheelspin.
Several reviewers suggest that outward visibility is an issue in the 2010 Challenger. According to ConsumerGuide, the Challenger's "roof design severely limits visibility to the rear corners." Car and Driver expands upon that criticism, finding that the "outward sightlines are hampered by thick pillars, fixed rear headrests, a low roof, and a long hood."
