Infiniti's Q70 offers enough refinement to merit consideration as daily driver for a senior executive that has been helped by a 2015 refresh that improved the vehicle's infotainment system and brought Japanese Ash wood trim into the interior.

The Q70 exists in its current generation that began in 2009 when Nissan offered the M37 and M56. Infiniti changed its vehicle nomenclature for 2013 and rolled out the Q70 and Q70L, a long wheelbase model that's 7.6 inches longer.

Infiniti offers the sedan with two engine choices — a 3.7L V-6 or 5.6L V-8 — in rear-wheel drive with an all-wheel option that adds $2,500 to the V-8 model.

The V-8 Q70 provides plenty of power to move metal that drives heavier than its German competitors that have lightened the load. Even with low fuel prices, it can be tough to justify the vehicle's EPA ratings of 16 miles per gallon in the city, 24 mpg on the highway, and 19 mpg combined — performance that I struggled to reach while testing the vehicle.

The Infiniti sedans also offer quirky heavily sculpted hoods that, while seem more understated than their SUV brethren, take some getting used to.

The Q70 offers impressive interior comfort features, especially with its eight-way powered front seats with climate control and comfy leather surfaces.

The Q70 retails for at least $63,755. Our model that included the Premium Select Edition with 20-inch wheels and interior upgrades would retail for $67,055.
