The Premium variant of the Q50 is the most value for money and comes with almost all the modern bells and whistles. There is no dearth of safety features and equipment in this trim, and the cabin too comes with several luxuries and amenities. With a starting price of $40,000, the Q50 Premium is definitely a great choice for the buyers of this segment.

2015 Infiniti Q50 Engine and Performance

7.0/10

The 2015 Infiniti Q50 gets the same 3.7L V6 engine which has impressed us with its performance, power delivery, and refinement in the past. On paper, the engine produces 328 hp of peak power, while the peak torque output stands at 269 lb-ft. This engine comes mated to a 7-speed automatic gearbox that channels power to the rear wheels as standard. An optional all-wheel-drive system is also on offer for those who need more capabilities and performance.

The gearbox is not only fast with the shifts but is fine-tuned to complement the power delivery of the engine. This helps the powertrain deliver a great driving experience. The low-end lag is well masked, and the engine starts coming to life once the tachometer crosses the 3,000 RPM mark. There are no harsh vibrations felt on the pedals or the steering wheels. In all, driving this car in urban traffic as well as on the highways is an effortless and blissful experience.

Despite being one of the most powerful cars in the segment, the Q50 is not the fastest during the 0-60 mph performance runs. However, in day-to-day driving scenarios, it's a great car and offers decent performance. The BMW 3 Series is only a little down in terms of power on paper but manages to be further ahead in real-world performance. When comparing the price tag, BMW is also the most expensive option in the competition.

2015 Infiniti Q50 Fuel Economy

6.0/10

The Infiniti Q50 is definitely not the most fuel-efficient car in the segment and offers average fuel economy figures. To start with, the car gets a claimed fuel economy of 20 MPG for city usage, while the highway economy stands at 30 MPG. The combined fuel economy figure is claimed to be 23 MPG. However, the fuel tank is quite generous and offers a 20-gallon capacity, resulting in a combined range of 460 miles.

The Q50 gets one of the biggest fuel tanks and thus offers one of the highest ranges on a single tank full of fuel. The fuel economy figures of the vehicle, however, are not the best in the segment. The Mercedes-Benz manages to perform the best in terms of economy, while the BMW comes close to it. The Infiniti is not made to look bad as the Lexus is even less fuel-efficient.

2015 Infiniti Q50 Interior

9.0/10

The interior of the 2015 Infiniti Q50 is well laid out and feels very premium and luxurious in addition to the sheer levels of comfort that it offers. The dashboard is ergonomically sorted, and all the buttons and controls are placed within the driver’s reach. In addition to this, there are a lot of storage spaces inside the cabin, and the front seats are spacious and comfortable. Both the front seats get an electric adjustment feature, while the driver’s seat also gets manual lumbar support adjustment. The front seats are also available with a heated function.

The rear seat bench is spacious, and the seats offer great support. The cushioning is well-balanced, hence making the vehicle suitable for long-distance travel. On the features front, the car comes with features like dual-zone automatic climate control, leather-wrapped steering wheel, tilt and telescopic steering wheel, an illuminated and lockable glove box, and several other features that also include keyless entry, push-button start, and auto headlamps. The build quality of the cabin is great, and the occupants enjoy a premium experience inside the cabin.

The cabin of the Q50 is spacious and comfortable, hence giving stiff competition to the rivals. It has the most spacious rear seats out of any car here along with adequate cargo capacity.

When comparing the cargo capacity, Merc offers the least at 12.6 cubic feet. Standout interior features include: 

  • 8-way power-adjustable driver’s seat with manual lumbar support

The audio system comprises a standard 6 speaker setup, while the higher trims get an Infiniti Studio on wheels by Bose that features a 14-speaker audio system. Standout infotainment features include:

  • Infiniti Studio on wheels by Bose 14-speaker audio system

2015 Infiniti Q50 Exterior

8.0/10

The design of the Q50 definitely looks great and gives the vehicle a strong road presence. The subtle design language gives the vehicle an elegant look that can be appreciated by the buyers. The higher trims get 19-inch alloy wheels that not only look nice but look extremely sporty and premium. The rear, however, feels a little too busy where the LED taillights grab all the attention. On the features front, the car gets projector LED headlights that also offer automatic functionality. Other features include the availability of DRLs, tinted glasses, and chrome trim.
