Overview

The 2011 Infiniti M37x makes for an excellent contender in the midsize sedan segment. With standalone trim on offer, the Infiniti M37x has a base MSRP of $49,200. It competes directly with the Lexus GS 350 AWD Sedan, the Mercedes-Benz E-Class 350 Sport 4MATIC Sedan, and the BMW 5 Series 535i xDrive Sedan. Only a 3.7L V6 engine is offered, mated to a 7-speed automatic transmission. Together, they produce 330 horsepower and 270 lb-ft of torque. Accelerating from 0-60 in 6.1 seconds, the M37x maintains a combined fuel economy of 20 MPG. Infiniti offers the M37x in 8 stunning colors, with the Liquid Platinum being a particular favorite of ours.

Buying Advice

The 2011 Infiniti M37x Sedan is a sporty and premium sedan offered at an impressive price point. It is a standalone trim while there are some packages offered. We recommend getting the Deluxe Touring package that adds a power rear sunshade, an in-car air purifier, upgraded leather upholstery and interior trim, and a 16-speaker Bose surround-sound stereo.
