Overview

The 2012 Infiniti M37x Sedan makes for an excellent contender in the midsize sedan segment. With standalone trim on offer, the Infiniti M37x has a base MSRP of $47,700. It competes directly with the BMW 5 Series 535i xDrive Sedan, the Mercedes-Benz E 350 Sport 4MATIC Sedan, and the more powerful Jaguar XF 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 5.9 seconds, the M37x maintains a combined fuel economy of 20 MPG. Infiniti offers the M37x in 7 stunning colors, with the Harbour Blue being a particular favorite of ours.

Buying Advice

The one trim option leaves you with no choice. Therefore, we recommend opting for the Premium package ($3,450) that adds heated and ventilated front seats, a navigation system, a heated steering wheel, and a 10-speaker Bose stereo with streaming Bluetooth audio and digital music storage improve comfort levels significantly.
