The Q70 is the flagship of the Japanese premium brand Infiniti. We'll test the Q70 2.2d with the 4-cylinder diesel engine Infiniti developed in cooperation with Daimler and with a 7-speed automatic transmission operated with steering wheel paddles.Even the entry-level version we drove has full LED headlights, chrome accents on the front grille, a rear-view camera, front and back parking sensors, and 18-inch wheel rims -- along with Infiniti's typically generous standard fittings.
