Hey guys! Let's dive deep into the heart of the 2017 Honda Accord Sport: its engine. If you're curious about what powers this popular sedan, you're in the right place. We'll cover everything from engine specs to performance, reliability, and even some common issues you might encounter. Buckle up, and let's get started!

Engine Specifications

The 2017 Honda Accord Sport primarily features a 1.5-liter turbocharged four-cylinder engine and a 2.4-liter naturally aspirated four-cylinder engine. Let's break down the specifics of each:

1.5-Liter Turbocharged Engine

• Engine Code: L15BE
• Displacement: 1,498 cc (91.4 cu in)
• Bore x Stroke: 73.0 mm x 89.5 mm (2.87 in x 3.52 in)
• Compression Ratio: 10.3:1
• Horsepower: 192 hp at 5,500 rpm
• Torque: 192 lb-ft at 1,600-5,000 rpm
• Fuel System: Direct Injection
• Valvetrain: 16-Valve DOHC VTEC

This engine is known for its balance of fuel efficiency and responsive power. The turbocharger helps deliver torque at lower RPMs, making it feel peppy around town. It’s a great choice for daily driving, offering enough punch for merging onto highways and overtaking other vehicles.

2.4-Liter Naturally Aspirated Engine

• Engine Code: K24W1
• Displacement: 2,356 cc (143.8 cu in)
• Bore x Stroke: 87.0 mm x 99.0 mm (3.43 in x 3.90 in)
• Compression Ratio: 11.1:1
• Horsepower: 185 hp at 6,400 rpm
• Torque: 181 lb-ft at 3,900 rpm
• Fuel System: Multi-Point Fuel Injection
• Valvetrain: 16-Valve DOHC i-VTEC

The 2.4-liter engine is a reliable workhorse. While it doesn't have the low-end grunt of the turbo, it delivers smooth and linear power throughout the rev range. Many drivers appreciate its simplicity and proven track record. Both engines are solid choices, and each offers a slightly different driving experience depending on your preferences.

Performance and Fuel Efficiency

How do these engines translate to real-world performance and fuel efficiency in the 2017 Honda Accord Sport? Let's take a closer look.

Acceleration

The 1.5-liter turbo engine generally offers quicker acceleration due to its higher torque output at lower RPMs. Expect 0-60 mph times in the mid-7-second range. The 2.4-liter engine is a bit slower, with 0-60 mph times typically in the low 8-second range. While the difference may not seem huge on paper, it's noticeable in everyday driving scenarios. The turbo engine feels more responsive and eager to accelerate.

Fuel Efficiency

Fuel efficiency is another area where the 1.5-liter turbo engine shines. EPA estimates for the 2017 Honda Accord Sport with the 1.5-liter engine are around 30 mpg in the city and 38 mpg on the highway. The 2.4-liter engine is still respectable, but slightly less efficient, with EPA estimates of around 26 mpg in the city and 35 mpg on the highway. Keep in mind that real-world fuel economy can vary depending on driving conditions, habits, and maintenance.

Driving Experience

The driving experience differs slightly between the two engines. The 1.5-liter turbo provides a more modern feel with its instant torque and smooth power delivery. It's well-suited for navigating city streets and provides ample power for highway cruising. The 2.4-liter engine offers a more traditional driving experience. It requires a bit more revving to get into its powerband, but it's still a capable and enjoyable engine to drive.

Reliability and Common Issues

Both engines in the 2017 Honda Accord Sport are generally reliable, but like any engine, they have some potential issues to be aware of. Here's what you should know.

1.5-Liter Turbo Engine Issues

• Oil Dilution: Some owners have reported issues with oil dilution, where fuel mixes with the engine oil. This can lead to premature wear and tear. Honda has issued software updates to address this issue, but it's still something to monitor.
• Turbocharger Problems: While not widespread, some owners have experienced issues with the turbocharger, such as leaks or failures. Regular maintenance, including oil changes, is crucial to keeping the turbo in good condition.

2.4-Liter Engine Issues

• Direct Injection Carbon Buildup: This is a common issue with direct injection engines. Carbon deposits can accumulate on the intake valves, reducing performance and fuel efficiency. Regular cleaning of the intake valves can help prevent this.
• VTC Actuator Rattle: Some owners have reported a rattling noise on startup, which can be caused by a faulty VTC actuator. This issue is usually more of an annoyance than a serious problem, but it's worth getting checked out.

General Maintenance Tips

Regardless of which engine your 2017 Honda Accord Sport has, following these maintenance tips can help keep it running smoothly:

• Regular Oil Changes: Use the recommended oil type and change it at the intervals specified in your owner's manual. This is especially important for the 1.5-liter turbo engine to prevent oil dilution issues.
• Air Filter Replacement: A clean air filter ensures proper airflow to the engine, which improves performance and fuel efficiency.
• Spark Plug Replacement: Replace the spark plugs at the recommended intervals to maintain optimal combustion.
• Check Coolant Levels: Ensure that the coolant level is adequate to prevent overheating.
• Inspect Hoses and Belts: Regularly inspect hoses and belts for cracks or wear.

Which Engine is Right for You?

Choosing between the 1.5-liter turbo and the 2.4-liter engine in the 2017 Honda Accord Sport depends on your priorities.

• If you prioritize fuel efficiency and responsive low-end torque, the 1.5-liter turbo is the better choice.
• If you prefer a more traditional driving experience and value simplicity, the 2.4-liter engine is a solid option.

Both engines are reliable and offer a good balance of performance and efficiency. Ultimately, the best way to decide is to test drive both versions and see which one you prefer. Consider your daily driving needs, typical driving conditions, and personal preferences when making your decision.

Swapping Engines

Thinking about swapping the engine in your 2017 Honda Accord Sport? While it's possible, it's not a straightforward process and comes with some serious considerations. Swapping an engine involves significant mechanical knowledge, time, and money. Plus, it could affect your car's warranty and resale value. It's usually more cost-effective to simply buy a car with the engine you want from the start.

Cost and Complexity

Engine swaps can range from a few thousand dollars to upwards of ten thousand, depending on the complexity of the swap and the cost of parts. You'll need to factor in the cost of the new engine, any necessary modifications to the engine bay, wiring harnesses, and potentially even the transmission and ECU. It's not just about dropping a new engine in; you'll need to ensure everything is compatible and working correctly.

Potential Issues

Engine swaps can lead to a variety of issues, including:

• Compatibility Problems: The new engine may not be fully compatible with your car's existing systems, leading to electrical or mechanical issues.
• Emissions Compliance: Swapping an engine can affect your car's ability to pass emissions tests, especially if the new engine is not certified for use in your vehicle.
• Safety Concerns: If not done properly, an engine swap can compromise the safety of your vehicle.

If you're seriously considering an engine swap, it's essential to consult with a qualified mechanic who has experience with Honda Accords. They can help you assess the feasibility of the swap and provide you with a realistic estimate of the cost and potential challenges.

Conclusion

The 2017 Honda Accord Sport offers a choice between two capable engines: the 1.5-liter turbocharged four-cylinder and the 2.4-liter naturally aspirated four-cylinder. Each engine has its own strengths and weaknesses, so it's important to consider your priorities when making a decision. Whether you value fuel efficiency, responsive power, or traditional simplicity, there's a 2017 Honda Accord Sport engine that's right for you. And remember, proper maintenance is key to keeping your engine running smoothly for years to come!
