Editor’s note: If you’re looking for information on a newer Infiniti Q50, which has replaced the Q40, we’ve published an updated review: 2019 Infiniti Q50 Review.
The 2015 Infiniti Q40 might be a new name for the brand, but the car itself is a familiar favorite. Formerly the 2013 Infiniti G37, the Q40 sedan works on many levels. This is partly the result of its brilliant driving dynamics but also because it excels at coddling its passengers. The Q40’s rear-drive layout is preferred by driving enthusiasts over the front-drive sedans from Acura and Audi, and its taut suspension delivers superb handling.
Available this year only with the V6 engine, the Q40 is priced slightly higher than some 4-cylinder entry-level competitors, but it still represents a remarkable value. The Q40 combines the attributes of a premium-brand car with an admirable reliability, repair and resale history. On the flip side, the Q40 doesn’t offer many newer technology and safety features, leaving those so inclined to shop for a BMW 3 Series, Audi A4 or Cadillac ATS.
What’s New for 2015?
Other than the obvious name change, the Q40 is nearly identical in configuration to the former G37. Sadly, the manual transmission and Sport package do not come along for the ride.
What We Like
Great V6 engine; available all-wheel drive (AWD); dynamic handling; strong resale and repair history; fluid styling
What We Don’t
No advanced telematics or app-oriented audio systems; uninspiring color choices; no manual transmission; interior materials feel dated
Under the Q40’s hood resides a 3.7-liter V6 — an engine shared with the Nissan 370, a performance legend. With 328 horsepower and 269 lb-ft of torque, the 3.7-liter engine has the muscle to make the Q40 a contender. See the 2015 Infiniti Q40 models for sale near you
Fuel economy figures are 19 miles per gallon in the city and 27 mpg on the highway with rear-wheel drive and 18 mpg city/25 mpg hwy when equipped with AWD.
Standard Features & Options
The 2015 Infiniti Q40 is offered in one trim, with the option of rear- or all-wheel drive.
The Q40 ($34,855) includes standard leather seating, 8-way power driver and passenger seats, intelligent keyless entry and push-button start, a rearview monitor, heated front seats, heated side mirrors, a tilt-telescopic steering wheel, Bluetooth, a 6-speaker AM/FM/CD stereo with a USB/iPod port, automatic climate control, cruise control and HID headlamps.
The Q40 AWD ($36,455) adds all-wheel drive.
There are two option packages for the Q40. The Moonroof package adds a power glass moonroof, while the Navigation Plus package adds a 10-speaker Bose audio system teamed with Infiniti’s hard-drive-based navigation, NavTraffic, NavWeather, and voice recognition for navigation, audio and vehicle information.
The Q40 sedan comes equipped with 4-wheel anti-lock brakes, electronic traction and stability control, and six airbags (front, front-side and side-curtain). The National Highway Traffic Safety Administration (NHTSA) has not yet tested the Q40, but the Insurance Institute for Highway Safety (IIHS) gave the 2013 G37 a rating of Good in the moderate front-overlap and side-impact tests, a rating of Average in the small-overlap and roof-strength tests, and a rating of Marginal in the head-restraint and front-seat tests.
Behind the Wheel
We’ll flat out say it: The Q40 is still one of our favorite performance sedans. In its most basic form, the 2015 Infiniti Q40 delivers exhilarating acceleration with razor-sharp handling. The Q40 lives for the curve, exhibiting excellent stability and tenacious grip. All-wheel drive makes a great car greater, but we long for the old 6-speed manual transmission, because the 7-speed automatic just isn’t as much fun.
The biggest drawback for us is the Q40’s lack of cutting-edge technologies, namely features such as adaptive cruise control, collision warning and mitigation, and an app-based audio system. The interior could also use some higher quality materials. At this price, there are just too many competitors that have better fuel economy and better features to consider the Q40 a top pick.
Other Cars to Consider
BMW 3 Series — The 3’s performance is still sharper than the Q40’s, but it can get pretty pricey once you start adding options. Then again, many of those options are not even offered on the Q40.
Acura TLX — The TLX has excellent reliability and resale numbers, and its V6 and available AWD easily rivals the Q40’s features. The Acura also offers a 9-speed transmission, a better ride and more features.
Cadillac ATS — The slightly smaller Cadillac ATS is better equipped, gets better fuel economy and offers handling that is equally adept as the Q40’s, with the added bonus of a manual transmission option.
Used Infiniti M37 — A 2011-2013 Infiniti M37 will give you all the performance and fun of the Q40, but with more luxury, more features and more interior room.
In this league, the best value is a loaded Q40 AWD with the Moonroof and Navigation Plus packages. Anything less just doesn’t hold up in this field of newer and better-equipped luxury performance competitors.
