Performance and Driving Experience

Okay, enough with the numbers! How does the 2021 Lexus IS 300 F Sport actually feel on the road? That’s what truly matters, right? The engine plays a massive role in defining the overall driving experience, and in the IS 300 F Sport, it strikes a great balance.

First off, the acceleration is smooth and linear. Thanks to the turbocharged engine, there's minimal turbo lag, which means the power comes on quickly when you need it.

The exhaust note is particularly pleasing under hard acceleration, providing a subtle but satisfying soundtrack to your driving experience. The combination of performance, handling, and sound makes the 2021 Lexus IS 300 F Sport a truly engaging and rewarding car to drive.

Fuel Efficiency

Let’s be real – fuel efficiency is super important. No one wants to spend all their cash at the pump! The 2021 Lexus IS 300 F Sport manages to strike a decent balance between performance and fuel economy. It’s not the most fuel-efficient car out there, but it’s also far from the worst.

The EPA estimates for the 2.0-liter turbocharged engine are around 21 MPG in the city, 31 MPG on the highway, and 25 MPG combined. These figures are pretty competitive for a sporty sedan in this class. Of course, your actual fuel economy will vary depending on your driving habits and conditions. If you have a heavy foot and enjoy pushing the engine, you can expect to see lower numbers. Conversely, if you drive conservatively and stick to the speed limit, you may be able to exceed the EPA estimates. Several factors can affect fuel economy, including the type of roads you drive on, the weather conditions, and the condition of your car.

One of the reasons the IS 300 F Sport achieves decent fuel economy is the use of advanced technologies like direct injection and variable valve timing. Direct injection helps to precisely meter fuel into the cylinders, optimizing combustion and reducing fuel waste. Variable valve timing adjusts the timing of the intake and exhaust valves to maximize efficiency across the engine's operating range. These technologies work together to improve fuel economy without sacrificing performance. In addition, the eight-speed automatic transmission helps to keep the engine in its optimal efficiency range by providing a wide range of gear ratios.

While the IS 300 F Sport requires premium unleaded fuel, the overall fuel costs are still reasonable, especially if you prioritize fuel-efficient driving habits. By driving smoothly, avoiding hard acceleration, and maintaining a steady speed, you can maximize your fuel economy and minimize your trips to the gas station. Regular maintenance, such as keeping your tires properly inflated and changing your oil regularly, can also help to improve fuel efficiency. These factors combined make the 2021 Lexus IS 300 F Sport a practical choice for drivers who want a sporty and enjoyable car without breaking the bank at the pump.
