Overview

The 2015 Infiniti Q40 makes for an excellent contender in the mid-size class. With standalone trims on offer, the 2015 Infiniti Q40 has a base MSRP of $33,950. It competes directly with the BMW 5 Series, the Acura TLX, and the Lexus ES 350. Only a 3.7L V6 engine is offered, mated to a 7-Speed Automatic transmission. Together, they produce 328 horsepower and 269 lb-ft of torque. 

Accelerating from 0-60 in 5.5 seconds, the Q40 maintains a combined fuel economy of 22 MPG. Infiniti offers the Q40 in 4 stunning colors, with the Liquid Platinum being a particular favorite of ours. 

Buying Advice

A few standard features offered on the Q40 are 17-inch alloy wheels, a rear window defroster, heated power front seats, leather upholstery, cruise control, a 7-inch color vehicle information display, and a 6-speaker sound system. Meanwhile, you can buy the optional power sliding moonroof and navigation package which includes a 10-speaker Bose sound system, Infiniti hard-drive navigation system with touch-screen, voice recognition, and other features.
