21 MPG combined isn’t going to win any awards, but for the 2016 Lexus RC 300 AWD, it accurately reflects what you get with this kind of experience. This isn’t a hybrid designed to maximize fuel savings; it’s a stylish coupe designed for comfortable cruising and a touch of sporty driving, and its all-wheel drive system adds confidence in any weather. Buyers aren’t prioritizing efficiency above all else. Instead, they value Lexus’s reputation for reliability, a luxurious interior, and distinctive styling, accepting the fuel economy as a trade-off for these qualities.

City and highway performance

The RC 300 AWD’s EPA estimates break down to 19 MPG in the city and 26 MPG on the highway. The city figure, unsurprisingly, is where the 3.5L V6 works the hardest, constantly accelerating, decelerating, and idling. This is where you’ll notice the fuel consumption the most, especially during stop-and-go traffic. The highway figure, while still not stellar, is more acceptable. The engine settles into a more efficient operating range at consistent speeds, allowing for decent mileage on longer trips. However, it’s important to remember that aggressive driving, even on the highway, will quickly diminish these numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Lexus RC 300 AWD at $2,750. This figure is based on driving 15,000 miles per year. It uses the EPA’s estimated combined fuel economy rating, assuming national average fuel prices. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use (premium is recommended), and local fuel prices. This estimate gives potential buyers a standardized benchmark for comparing fuel costs across different vehicles, even if the exact amount will change from person to person. It’s also important to factor in maintenance costs of premium fuel vehicles.

Real-world expectations

While the EPA provides a standardized testing protocol, real-world fuel economy often differs. RC 300 AWD owners often report figures close to the EPA estimates, especially when driving conservatively. However, factors like driving style, terrain, and weather conditions can all impact fuel consumption. Expect to see lower MPG if you drive aggressively or frequently drive in hilly areas. Cold weather can also negatively affect fuel economy, particularly during shorter trips when the engine hasn’t fully warmed up. Check RC MPG across all years for more accurate expectations.

How it compares

The fuel economy of the 2016 Lexus RC 300 AWD places it in a specific segment of sporty coupes where efficiency isn’t always the top priority, even among competing luxury vehicles. For instance, a similarly equipped BMW 435i xDrive coupe offers comparable performance but manages slightly better figures, around 22 MPG combined. The Infiniti Q60, another contender, lands roughly in the same ballpark with an estimated 22 MPG combined for its V6 all-wheel-drive variant. The Mercedes-Benz C300 Coupe, while offering a turbocharged four-cylinder as its base engine, achieves significantly better fuel economy, closer to 28 MPG combined, but with a different driving experience. These comparisons are crucial because they emphasize that the Lexus RC 300 AWD buyer is likely willing to sacrifice a few MPGs for the Lexus brand’s allure and its particular blend of luxury and sportiness, knowing all Lexus fuel economy data can be reviewed online. They are willing to pay more for the experience the brand brings despite cheaper options being available.

Tips to maximize efficiency

One of the easiest ways to improve fuel economy in the RC 300 AWD is to drive smoothly and avoid aggressive acceleration. The six-cylinder engine responds well to a gentle touch, and excessive throttle input only wastes fuel. Anticipate traffic flow, maintain a safe following distance, and allow the car to coast whenever possible.

Proper tire inflation is critical for optimal fuel efficiency. Check your tire pressure regularly and maintain it at the recommended levels, which can be found on a sticker inside the driver’s side doorjamb. Underinflated tires create more rolling resistance, which reduces fuel economy, but they also wear your tires out more quickly.

Regular maintenance is essential for keeping your RC 300 AWD running efficiently. Make sure to follow the recommended maintenance schedule, including oil changes, air filter replacements, and spark plug inspections. A well-maintained engine will always deliver better fuel economy than one that is neglected.

Avoid unnecessary idling. If you’re going to be stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, so idling is simply wasting gas. While this vehicle doesn’t have start/stop functionality, the principle is still the same: if you expect to be sat still for longer than about 60 seconds, switch it off.
