The M37 is the entry-level model in Infiniti's M midsize luxury sedan lineup, which also includes the M Hybrid and the V8-powered M56. It boasts sporty rear-wheel-drive handling dynamics, a well-designed interior and loads of optional high-tech features wrapped together in a high-value package.
Flowing, organic lines coupled with an athletic stance define the M37's exterior. The theme carries over in the spacious interior, which is constructed from high-quality materials and features a somewhat button-filled center console thanks to the lack of an iDrive-style control knob.
Despite being the least expensive M model, the M37 still features a punchy 3.7-liter V6 that makes 330 horsepower and 270 lb-ft of torque. The engine is mated to a seven-speed automatic transmission that offers rev-matched downshifts. While the powertrain combo makes for swift acceleration, it isn't as strong in the realm of fuel economy, which is rated at 18 mpg in the city and 26 mpg on the highway (many rivals return 30 mpg or more on the open road). Those living in northern climates can opt for the M37x, which utilizes an all-wheel-drive system that enhances traction in inclement weather but takes a one mpg city, two mpg highway toll on gas mileage.
Standard and Optional Features
The M37 represents a strong value due to its high level of standard features, with highlights include leather upholstery, genuine ash wood trim, heated and power-adjustable front seats, a sunroof, dual-zone automatic climate control, an intelligent key with push-button start, a seven-inch information display, a rearview parking camera, Bluetooth smartphone connectivity, 18-inch aluminum wheels and a six-speaker AM/FM/CD audio system with a USB input and XM satellite radio.
