Model Highlights

The 2015 INFINITI Q40 sedan comes powered by INFINITI's fantastic 3.7L V6, which produces 328 horsepower and 269 pound-feet of torque and is mated to a 7-speed automatic transmission. The transmission features manual shift mode along with Adaptive Shift Control (ASC) and Drive Sport (DS) modes. Rear-wheel drive is standard, while all-wheel drive is available, instantly adapting to changing road surfaces and conditions by sending power to the wheels that need it most, enhancing traction and control in less-than ideal driving situations.

The Q40 comes in one well-equipped trim. This includes 17-inch alloy wheels, HID xenon headlights and LED brake lights, INFINITI Intelligent Key, leather seating with heated front seats and 8-way power adjustability, power everything, dual-zone automatic climate control, Bluetooth hands-free connectivity, a rearview monitor, speed-sensing wipers, and an AM/FM/CD stereo with MP3 compatibility.

A moonroof is available, as is the $2,900 Navigation Plus Package, which adds navigation, a Bose stereo, streaming audio, DVD video playback and voice recognition.

A host of airbags are standard, as are anti-lock brakes, electronic brake force distribution, brake assist, traction control and a security system.

Model News

INFINITI's entry-level sport sedan, the G37, took the year off in 2014. In the meantime, the luxury carmaker introduced the Q50 as its replacement. For 2015, however, the G37 returns -- virtually unchanged from its 2013 form -- but is rebadged as the Q40. The car comes in one trim, with either rear- or all-wheel drive, and is powered by the venerable 3.7L V6, which makes 328 horsepower. A 7-speed automatic is the only transmission available. EPA-estimated fuel economy for the rear-drive car is 19 mpg in the city and 27 mpg on the highway.

Value Writeup

The 2015 INFINITI Q40 is made for luxury sport sedan enthusiasts on a budget. Its powerful V6 and rear-drive layout make it ideal for spirited driving, while its modest $33,950 pricetag sets it well below rival cars in its class such as the BMW 3-Series, Lexus ES and GS and Acura TLX.

Crash Test Rating


Overall Rating: Not Rated

Overall Frontal Barrier Crash Rating: Not Rated

Overall Side Crash Rating: Not Rated

Overall Rollover Rating: * * * * *
Dynamic Test Result: No Tip
Risk of Rollover: 10.1%

Note Regarding Driver Rating:

Male: Average sized adult male dummy in 35-MPH crash into fixed barrier. Rating is evaluation of injury to head, neck, chest, legs. Female: Small-sized adult female dummy in 35-mph crash into fixed barrier. Rating is evaluation of injury to head, neck, chest, legs.

Rollover Note: Dynamic (moving) test results (Tip or No Tip) and measured rollover-related properties determine vehicle's risk of rollover in single vehicle crash and its rollover rating. The Rollover Resistance Rating utilizes a "fishhook" maneuver which is a series of abrupt turns at varying speeds to see how "top-heavy" a vehicle is.
