Music played through a 10-speaker Bose audio system, which came courtesy of the Premium package included with CNET's test car. This system delivers solid sound, well-balanced but lacking delicacy or a big punch. Listening to a Django Reinhardt collection, guitar and violin on each track came through clearly and were easy to distinguish, but I would have liked a brighter reproduction. The more bombastic production of tracks by Florence and the Machine could have also done with more robust bass.
Ready to pounce
The G37 drove like I expected from earlier versions. The suspension delivered an overall taut feeling, partly due to the Sport package Infiniti included in this car. That package combines a more rigid suspension with a limited-slip differential and 18-inch alloy wheels wrapped in Bridgestone high-performance summer tires. With the sport tuning, rough sections of road became slightly uncomfortable, as the car transmitted bumps and jolts to the cabin.
On smoother sections of road the G37 felt like the premium sedan it purports to be. Still using a hydraulic power-steering boost system where many other automakers have gone to electric, the steering wheel maintains a comfortable amount of heft and resistance at speed. In low-speed maneuvering, it doesn't become overboosted, requiring a little effort to turn.
The engine should be more than familiar to anyone who follows Nissan and Infiniti vehicles. We most recently saw it here at CNET in a. This 3.7-liter V-6 uses variable valve timing, producing 328 horsepower and 269 pound-feet of torque. Stepping on the gas, I didn't feel all that power at once. Instead, there was about a half second where the car marshaled its forces, then let it rip.
This engine has earned plenty of praise over the years, but its days of appearing on the Ward's 10 Best Engines list are probably over, as other automakers have been pushing direct injection and forced injection to enhance efficiency. In this application, it gets the G37 19 mpg city and 27 mpg highway, still fairly average numbers but quickly being outstripped by the competition.
The seven-speed automatic didn't seem prone to seeking low engine speeds through short shifting, maintaining power on tap. In Drive mode, it was ready to shift down as quickly as the torque converter transmission could handle. In manual mode, shifting with the wide paddles fixed to the steering column, I got a sense of the slushy gear changes. Pull the left paddle for a downshift, wait a portion of a second, then feel the power come on and watch the tachometer needle jump.
Somewhat more supportive for playful driving was the transmission's Sport mode. While suffering from the same slushy gear changes, its programming told it to downshift as I jammed on the brakes ahead of a turn, then hold that lower gear as I accelerated through. It let the engine speed run up to 5,000rpm for extended periods of time, when I modulated the gas pedal correctly.
The Bridgestones included with the Sport package were not the best for even the light misting of a San Francisco Bay Area autumn. In just about any turn, they felt like they were ready to break loose, and the traction control stepped in frequently.
Finding its element
During my time with the 2013 Infiniti G37, I found it an enjoyable and easy car to drive. It was in its element buzzing around suburban streets, but I didn't like how quickly the fuel needle dropped in the city. For long freeway cruises, a softer suspension would have been nice, while the automatic transmission does not quite hold its own on a winding mountain road.
The cabin tech is absolutely solid, full of useful features that perform readily. With both a USB port and Bluetooth audio streaming, it should work with the gadgets most people bring into the car. The navigation system gave good route guidance, and the inclusion of traffic data is a necessity in a premium vehicle. However, the lack of any connected features for destination search or social-media integration show the G37's age.
