22 MPG combined is not why someone buys a 2016 Infiniti Q50S Red Sport 3.0L. Buyers seeking ultimate efficiency look elsewhere. This is a performance-oriented sedan, and the turbocharged V6 under the hood is the priority. Fuel economy is secondary to the thrill of 400 horsepower and spirited drives. The MPG figure is simply a cost of entry, a compromise accepted for the engine’s satisfying power.

City and highway performance

The EPA estimates of 20 MPG in the city and 26 MPG on the highway reveal a predictable tradeoff. City driving, with its constant stops and starts, takes a heavier toll on fuel consumption. The Q50S Red Sport’s responsive throttle and eagerness to accelerate from every light contribute to the lower city MPG. Highway driving allows the engine to settle into a more efficient cruise, yielding the higher 26 MPG figure. However, even on the highway, the temptation to the power will impact your real-world fuel economy. The seven-speed automatic transmission, while generally smooth and responsive, can be slow to upshift when driven aggressively, further impacting efficiency.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2016 Infiniti Q50S Red Sport 3.0L is $2,650. This figure is based on driving 15,000 miles per year and using national average fuel prices. But actual fuel costs will vary depending on driving habits, local fuel prices, and the type of fuel used. The Q50S Red Sport requires premium fuel to achieve optimal performance and efficiency, which increases the annual fuel expense. Remember that the annual fuel cost could easily climb above $3,000 for drivers who accelerate quickly.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy for the 2016 Q50S Red Sport often falls short. Drivers who regularly the engine’s power can expect to see combined MPG figures closer to 18-20 MPG. Those who prioritize efficiency and drive conservatively might achieve the EPA’s 22 MPG, but it requires effort. Terrain also plays a role; hilly areas will see lower MPG figures than flat, open roads. Consider your typical driving conditions when evaluating the Q50S Red Sport’s potential impact on your wallet.

How it compares

Compared to its rivals, the 2016 Infiniti Q50S Red Sport 3.0L sits in the middle of the pack in terms of fuel economy. The BMW 340i, for example, achieves a slightly better 25 MPG combined, for those who want performance and better fuel economy. The Mercedes-Benz C400 4MATIC, with its V6, manages around 23 MPG combined. Audi’s S4, can achieve around 24 MPG. However, it’s important to remember that these figures represent a compromise. Higher-performance versions of these cars, like the BMW M3 or Mercedes-AMG C63, result in a significant drop in fuel economy, often landing in the 17-19 MPG range. For buyers cross-shopping the Q50S Red Sport, fuel economy is one factor among many, including performance, styling, and value.

Tips to maximize efficiency

Use the Q50S Red Sport’s drive mode selector. The “Standard” or “Eco” modes reduce throttle response and shift patterns to prioritize fuel efficiency. These modes may slightly dampen the car’s performance, but they can make a noticeable difference in fuel consumption, especially during daily commuting.

Avoid aggressive acceleration and braking. The Q50S Red Sport’s powerful engine is tempting, but doing so frequently will deplete fuel quickly. Instead, accelerate smoothly and gradually, and anticipate traffic conditions to minimize hard braking. The smoother your driving style, the better your fuel economy will be.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended levels specified in the owner’s manual or on the driver’s side doorjamb. Correct tire pressure improves fuel economy and enhances handling and tire life.

Minimize idling time. Idling wastes fuel and creates emissions. If you’re stopped for more than a minute or two, turn off the engine. Modern cars like the Q50S Red Sport are designed to restart quickly and efficiently, so there’s no need to let the engine run unnecessarily. This simple change can help your overall fuel economy.
