For 2014, Infiniti has renamed its former M midsize luxury sedan the Q70, but there are only a few actual changes. Fuel economy is improved on the Q70 Hybrid, which has a 31 mpg EPA combined rating -- up from 29 combined on last year's M35 Hybrid. Beyond that, rear-wheel-drive 2014 Infiniti Q70s with the Sport package have revised suspension tuning, and all 3.7 Sport models get a supplemental engine oil cooler. The optional four-wheel active steering system is no longer available.

In case you haven't heard, has renamed its M midsize luxury sport sedan the Q70 starting this year. Otherwise, the 2014 Infiniti Q70 is little changed from the car formerly known as the M35h, M37 and M56.
