But when you push the accelerator harder and the engine revs climb, VTEC kicks in, changing the valve timing and lift to allow for more air and fuel to enter the combustion chamber. This results in a significant boost in power and torque, giving you that extra surge when you need it most – like when you're overtaking or accelerating quickly. It’s a clever bit of engineering that makes the engine feel more potent than its displacement might suggest. The 2021 Civic Sport’s 2.0L engine produces 158 horsepower at 6,500 rpm and 138 lb-ft of torque at 4,200 rpm. While these numbers are solid, it's the delivery of that power that truly shines. Honda has tuned this engine to feel lively and responsive, especially when paired with the available six-speed manual transmission. Even with the CVT, which is designed for maximum efficiency, Honda has programmed it to mimic a more traditional gear shift under acceleration, providing a more engaging feel. The engine also features direct injection, which further enhances combustion efficiency, leading to better power output and improved fuel economy. Plus, it's built with Honda's legendary reliability in mind. These engines are known to last for hundreds of thousands of miles with proper maintenance. So, when you're looking at the 2021 Civic Sport, you're not just getting an engine; you're getting a proven, technologically advanced powerplant that’s designed to be both fun to drive and dependable for the long haul. It’s this attention to detail in engine design that sets Honda apart and contributes to the Civic’s enduring popularity. The VTEC system, combined with direct injection, makes this engine a remarkably capable unit for its class, offering a driving experience that often punches above its weight.

On the other hand, you have the Continuously Variable Transmission (CVT). Now, CVTs sometimes get a bad rap, but Honda's implementation is among the best. For the Civic Sport, the CVT is tuned to be more responsive than in some other Honda models. It does an excellent job of keeping the engine in its sweet spot for optimal power delivery and fuel efficiency. It provides a smooth, seamless acceleration without the distinct 'shifts' you feel in a traditional automatic. For daily commuting, especially in stop-and-go traffic, the CVT can be more relaxing and fuel-efficient. To make it feel more engaging, Honda has programmed the CVT in the Sport model to simulate gear shifts under acceleration, which helps reduce that droning sensation some people associate with CVTs. So, which one should you pick? It really boils down to your personal preference and driving style. If you crave maximum driver involvement and the joy of shifting gears yourself, the manual transmission is an absolute must. It transforms the driving experience and makes the Civic Sport feel even sportier. If you prioritize smoothness, ease of use in traffic, and potentially slightly better fuel economy in certain conditions, the CVT is a fantastic and well-executed option. Both transmissions are paired effectively with the 2.0L engine, ensuring that whether you choose to shift for yourself or let the car do the work, you'll have an enjoyable and capable driving experience. It's great that Honda still offers this choice, catering to a wider range of drivers and their desires for how they want to interact with their car. The decision between the two really enhances the overall appeal of the 2021 Honda Civic Sport.
