About the 2018 INFINITI Q70

Y51-based Q70 generation, introduced under the Q70 name for 2014; 2018 is a late-cycle update year focused on naming and packaging rather than major hardware changes.

INFINITI positions the Q70 as its premium large sedan for shoppers who want strong engine choices, a quiet cabin, and distinctive styling without moving into a full-size luxury flagship. Across the range, the Q70 emphasizes smooth power, upscale materials, and a more personal, driver-focused feel than some larger luxury sedans. The model range also offers a broader spread than many rivals, with V6, V8, and hybrid powertrains.

The 3.7 LUXE is the core Q70, with a 330-hp V6, heated power front seats, a moonroof, and LED lighting. The 5.6 LUXE steps up to a 420-hp V8 and richer cabin technology, while the Hybrid LUXE pairs a V6 with an electric motor; the L-designated versions put more emphasis on rear-seat comfort.
