The 2018 Honda Civic Sport trim comes with two engine options, but when we're talking about the "Turbo" model, we're specifically referring to the 1.5-liter turbocharged inline-4 engine. This engine is the powerhouse that gives the Civic Sport its peppy and engaging driving experience. So, what kind of numbers are we looking at?

• Horsepower: The 2018 Honda Civic Sport with the 1.5-liter turbo engine produces 180 horsepower at 6,000 rpm. This is a significant jump from the base engine offered in some other Civic trims, giving the Sport model a noticeable edge in acceleration and overall responsiveness.
• Torque: Horsepower isn't the whole story. Torque, which is the rotational force that gets you moving, is also crucial. The 2018 Civic Sport Turbo delivers 177 lb-ft of torque between 1,900 and 5,000 rpm. This broad torque curve means you have plenty of pulling power available across a wide range of engine speeds, making it fun to drive in various situations, whether you're merging onto the highway or navigating city streets.
• Engine Configuration: The engine is a 1.5-liter DOHC (Dual Overhead Camshaft) 16-valve inline-4 cylinder with direct injection. The turbocharger helps force more air into the engine, allowing it to burn more fuel and produce more power than a naturally aspirated engine of the same size. The direct injection system ensures precise fuel delivery, optimizing combustion for both performance and efficiency.
• Transmission Options: The 2018 Civic Sport Turbo is available with either a 6-speed manual transmission or a continuously variable transmission (CVT). The manual transmission gives drivers more control and a more engaging driving experience, while the CVT provides smooth and seamless acceleration, prioritizing fuel economy.

Performance Characteristics

The horsepower and torque figures only tell part of the story. The way the 2018 Civic Sport Turbo delivers its power is just as important. Here’s a breakdown of its performance characteristics:

• Acceleration: Thanks to its 180 horsepower and 177 lb-ft of torque, the 2018 Civic Sport Turbo can accelerate from 0 to 60 mph in around 6.8 to 7.0 seconds, depending on the transmission and testing conditions. This is respectably quick for a compact car and makes it enjoyable for daily driving.
• Handling: The Civic Sport isn't just about straight-line speed. It also boasts sharp and responsive handling, making it fun to drive on winding roads. The sport-tuned suspension, along with the car's relatively low weight, contributes to its agile feel.
