About the 2012 INFINITI EX

1st generation EX (2008-2013), fifth model year; no redesign for 2012.

Infiniti positioned the EX as a small luxury crossover for buyers who wanted a more personal, sporty feel than a typical compact SUV. The brand emphasized its coupe-like shape, strong V6 performance, upscale cabin materials, and city-friendly size, while reviewers consistently called out its quick acceleration and nimble handling. Its main draw was not maximum rear-seat or cargo space, but premium feel and responsive driving in a compact package.

The EX35 was the simpler version, pairing a 297-hp V6 with leather seating, a 7-inch display, and a rearview camera. The more fully equipped EX35 Journey added heated front seats, a moonroof, Bluetooth phone connectivity, maple interior trim, and standard HomeLink.
