The 2015 Volkswagen CC is a reasonably safe pick, although a few issues keep us from declaring it one of the safest larger sedans.
First and foremost, the CC only earns a 'marginal' score in the new Insurance Institute for Highway Safety (IIHS) small overlap frontal impact test. It scores the top rating, 'good,' in the rest of the IIHS tests.
The CC hasn't changed structurally in many years; it's based on the previous-generation Passat family. It received four out of five stars in the government's rollover test, and despite the worrisome rating from the IIHS, it does well in the Institute's other crash tests--though it's no longer a Top Safety Pick, due to that "marginal" score.
The other concern is that the CC's outward visibility is compromised by its stylish design, making the view out almost as bad as in a smaller two-door coupe. The steeply raked windshield is small, the fast backlight produces a narrow slit to look out of when backing up, and the short side windows can create a challenge when checking blind spots before changing lanes.
Volkswagen has remedied the rearward visibility issue with a rearview camera system that's included on most trim levels for 2015. And otherwise, the safety-feature set is great--including side and side-curtain airbags, electronic stability control, and anti-lock brakes are all standard in the CC, and rear side bags, a feature not always offered in this class, are optional. Front and rear parking aids are offered in the CC, but they're still the exclusive domain of the top VR6 4Motion Executive.
