The Chevy Impala's architecture is nearly a classic at this point in time, dating back nearly 25 years if you trace its lineage to the W-cars of the 1980s. That said, its safety record has held up remarkably well, with good but not great crash-test scores making up for a lack of advanced safety features.In the National Highway Traffic Safety Administration (NHTSA) crash tests, the Impala fares quite well, with four out of five stars in both frontal and side impact. The Insurance Institute for Highway Safety (IIHS) gives the Impala top 'good' ratings for frontal and side impact, but this Chevy earns only 'acceptable' for rear impact and roof strength.
Standard features have been kept up-to-date. The 2013 Impala comes with standard dual front, side and curtain airbags; anti-lock brakes, traction and stability control; and the OnStar emergency and concierge system is of course included. It's the modern active-safety options that are lacking--features like blind-spot systems, parking sensors, or rearview cameras, that have been trickling down to the mass market the past couple of model years. Those are planned for the new Impala that arrives as a 2014 model next year.
