2011 Infiniti M

Quick, quiet, and roomy, the 2011 redesign also performed well. A not-so-impressive rear-drive hybrid version was also introduced. The optional Technology Package adds a variety of safety aids. These include lane keep assist, which can also prevent changing lanes into an unseen car. The active cruise control function has autonomous braking, as well as a forward-collision warning system. Model year 2014 brought a name change to Q70. Styling was facelifted for 2015, which also marked the introduction of a long-wheelbase Q70L model.

Brand context

About Infiniti

Nissan’s luxury sub-brand sells stylish vehicles that deliver mixed results. Fit and finish is usually good, especially in the quiet, luxurious interiors. But Infiniti often falls short of competitors in fuel economy and handling. Some of its vehicles also score low in our owner satisfaction surveys, and most new models scored average for predicted reliability. New vehicles come standard with a full suite of active safety and driver assist systems. The brand’s lowest-priced option is a two-row compact SUV with a variable compression engine that attempts to deliver both fuel economy and sporty performance. The brand’s larger midsized, three-row SUV is roomy and quiet, with competitive fuel economy and quick acceleration. The largest Infiniti is a large three-row, high-end SUV that competes against Land Rover and Mercedes-Benz. With options, its price can cross $100,000. Among Infiniti’s discontinued vehicles, some sedans and coupes can be recommended among used luxury cars.
