The 2015 INFINITI Q40 offers a unique combination of world-class performance, seductive styling and modern craftsmanship. Previously named the INFINITI G37 Sedan, it is available in two well-equipped models: the INFINITI Q40 and INFINITI Q40 AWD.
Like the other luxury performance sedans in the INFINITI portfolio – the redesigned flagship Q70 and stunning Q50 – the Q40 features a strikingly seductive exterior defined by its sleek wave-form hood, raked A-pillars, signature LED taillights and athletic stance.
Inside, the Q40 provides a crafted, heritage-inspired interior environment and standard features such as leather-appointed seating, Intelligent Key with Push Button Ignition and RearView Monitor
Every 2015 INFINITI Q40 comes equipped with a 328-horsepower 3.7-liter VVEL V6 mated to a responsive 7-speed automatic transmission, which along with the 4-wheel independent suspension combine to provide responsive acceleration and agile handling. The Q40 AWD model adds INFINITI's ATTESA E-TS® Intelligent All-Wheel Drive system.
Two option packages are offered for 2015. The Navigation Plus Package features the INFINITI Hard Drive Navigation System and audiophile-quality INFINITI Studio on Wheels® by Bose®. The Moonroof Package includes a power sliding glass moonroof with one-touch open/close tilt feature.
