About the 2014 INFINITI Q70

Y51 generation (2011-2019 U.S. run); first year wearing the Q70 name and the last year before the 2015 exterior refresh.

The Q70 is Infiniti’s flagship sedan for buyers who want a roomy, rear-drive-based luxury car with a stronger performance feel than many softer rivals. Infiniti marketed it around style, performance, luxury, craftsmanship, and technology, with a choice of V6, V8, or hybrid power. Its core appeal is a quiet, upscale cabin, strong straight-line power, and a more driver-focused personality than the typical comfort-first executive sedan.

The Q70 remained INFINITI’s roomy flagship sedan, with three distinct versions. The 3.7 used a 330-hp V6, the 5.6 paired a 420-hp V8 with navigation and Bose audio, and the 360-hp Hybrid emphasized stronger fuel economy while retaining luxury-sedan performance.

What changed, by category

Powertrain

The 3.7 Sport added an engine oil cooler. The Hybrid’s EPA ratings improved to 29 mpg city, 34 mpg highway, and 31 mpg combined.

Suspension

Rear-wheel-drive models equipped with the Sport Package received revised suspension tuning.
