The Luxe available with all three powertrains and optional packages adds many features providing more flexibility. The 300-horsepower 3.0-liter twin-turbocharged V-6 engine delivers a strong performance in the Luxe trim. If you feel 300-horses are not enough the Red Sport with a stronger V-6 that delivers 400-horsepower should be your answer but it does come at a price.

Power comes effortlessly on both the 300-horsepower V-6 and the 400-horsepower V-6 engine in the Red Sport 400. Both the engines are much zestier with great acceleration. Turbo lag is minimum with impressive driving dynamics. The sound from the engine is remarkable with a resonant V-6 exhaust note. Meanwhile, the Hybrid Q50 is the most fuel-efficient on the roster and is powerful too. It is also mated to a V-6 engine and an electric motor that together produce 360-horsepower.

The Red Sport 400 is equipped with a much powerful V-6 that churns out 400-hp and 350-pound-feet of torque, it is one of the best in the class when it comes to performance. There is a 7-speed automatic transmission on each engine with no manual option. Rear-wheel drive comes standard on both the engine and you get all-wheel drive as an option. The Q50 gets an updated suspension and improved steering which feels light and quick to respond. Handling is agile and there is not much body roll while cornering. 

The 2018 Infiniti Q50 is the quickest of the lot in completing the 0-60 sprint at only 5.7 seconds, which is the best in the class. The closest rival Volvo S60 and the Mercedes C300 take good 6.5 seconds in going from 0-60. However, there is a catch, the Q50 impresses with early acceleration but it fails to hold its ground when it comes to covering a quarter-mile. From being the fastest it drops to be the slowest by taking 15.9 seconds for a quarter-mile. Brakes feel strong and easy to modulate with a braking distance of 109-feet which is best in the segment.

Well, you can't have everything, and the Q50 drops quite low in terms of fuel efficiency in the class. The base engine earns an EPA rating of 23 mpg city and 30 mpg highway. Things become worse from poor as the V-6 engine is rated at 20 mpg and 29 mpg on the highway. The Red Sport with 400 horsepower gets you 20/26 mpg. However, all is not lost with the Infiniti Q50 as the Hybrid comes as a savior. It is rated at 27 mpg city and 32 mpg highway. Not to mention these ratings are still only slightly better than the most non-hybrid cars in the class. 

The Infiniti in comparison has the biggest fuel tank of 20 gallons and the highest overall range of 500miles, followed by the Mercedes C300 with its 17.4-gallon tank and 469 miles of combined range. The BMW 320i is in third place with a fuel capacity of 15.8 gallons and a combined range of 442miles. The Volvo S60 comes in at last with a 15-gallon tank and a combined range of 435 miles.

Infiniti has stuck to its design which is almost a decade old now, however superior material has been used in the cabin of 2018 Q50. It feels robust from the inside and all the controls are within reach. The interior of the Infiniti Q50 as compared to the newer luxury sports sedans feels average. 

The 2018 Infiniti Q50 is very quiet even at highway speed. Getting in and out of the car is easy. Infiniti's seats are extremely comfy and offer plenty of support to the drivers.

2018 Infiniti Q50 Infotainment System

The dual touch screen makes things a bit complicated inside the cabin of the 2018 Infiniti Q50, although it is quick to respond and easy to navigate. Both the screens perform different functions, the upper 8-inch touchscreen unit is the viewer for the rearview camera and navigation system while the lower 7-inch touchscreen unit displays audio, climate, and other systems.

An uncommon feature that the car boasts is that its upgraded climate control system includes an air purifier which is not found in most luxury cars. Standard feature includes:

• HD radio
• Two USB ports
• A rearview camera

Visual differences within the trims are quite prominent. The Pure and the Luxe trim gets a 17 or 18-inch alloy wheel, a smaller fog light, and a body-color exhaust while the Sport and the Red Sport 400 comes with a dark chrome, larger wheel size, and fog light.

It also distinguishes itself further with a black lower-bumper section and a distinct body-color diffuser. Looking at the sides the story remains almost the same with no noticeable changes. Only the windows have now been finished with gloss black matching the side view mirrors. From the back, the taillight has been updated to give a more modern look. 

The Infiniti has the longest wheelbase of 112.2” resulting in the best second-row space, followed by the Mercedes-Benz C300 sedan. The Volvo S60 has the shortest wheelbase among the competition on the list.

Infiniti Q50 Vs BMW 320i

The BMW 3 Series is far more athletic than the Q50. It is one of the sportiest luxury sedans in the market. BMW offers several engine options, while the zesty M3 churns out more horsepower than the Q50 Red Sport 400. It also offers better fuel economy and handling is buttery smooth. Interior gets a plethora of tech features with comfortable seating for adults making it a better choice than the Q50. BMW does come at a price but that is justifiable.

Infiniti Q50 Vs Mercedes C300

Let’s talk about Mercedes-Benz C-Class because comparing the two will be like adding insult to injury for the Q50. The Infiniti, however, scores a point in terms of pricing as Benz is one of the most expensive in the lot. Apart from pricing, there is no reason to choose Infiniti. The C-class showcases a well-designed cabin, comfortable seats, and a surfeit of features. It is also available as convertible and on-road performance is outstanding with better fuel economy.

Infiniti Q50 Vs Volvo S60

There is not much difference in the pricing between the two cars however passengers will feel more comfortable in the back seat of the Infiniti as it offers better legroom. The Volvo although scores better when it comes to fuel efficiency. Overall, you will be happy in an Infiniti as it delivers exciting performance and more available features than the Volvo S60.

There are some things that the Q50 is good at and there are some which it is not. A powerful engine, decent trunk space along active safety features are some of its impressive features. It is however not a class leader in any area along with some notable shortcomings, like fuel efficiency. It is well equipped and relatively cheaper than other luxury cars in the segment but doesn't match up to Germany's finest yet. With so many better options available in the market it is hard for us to recommend the Infiniti Q50 to the buyers.
