What engine does an Acura CSX have?
The Acura CSX uses a 2.0-liter inline-four i-VTEC engine, paired with front-wheel drive. It delivers roughly 155 horsepower, making it a Civic-based powerplant tuned for everyday reliability rather than high-end performance.
Engine design and origins
The CSX is the Canadian-market successor to the Honda Civic sedan wearing Acura branding. Its powerplant is a 2.0-liter four-cylinder i-VTEC unit derived from Honda’s Civic engine family. The i-VTEC system adjusts valve timing and lift to optimize efficiency and mid-range pull, while keeping emissions and fuel economy within target ranges for a compact sedan.
What that means for performance
With the 2.0-liter i-VTEC, the CSX prioritizes smooth, usable power across the rev range rather than outright sportiness. The engine is typically paired with a five-speed manual or a five-speed automatic transmission in most trims.
Here are the typical figures for this engine across model years:
- Engine: 2.0-liter inline-4 i-VTEC
- Horsepower: approximately 155 hp (about 115 kW)
- Torque: approximately 139 lb-ft (188 Nm)
- Valvetrain: DOHC with i-VTEC
- Drivetrain: Front-wheel drive
- Transmission options: 5-speed manual or 5-speed automatic
These figures are representative for most CSX models; exact outputs can vary slightly by market and year due to emissions tuning and available transmissions.
Year and trim variations
Across its production run (roughly 2006–2011 in Canada), the CSX retained the same 2.0-liter i-VTEC engine, with minor tuning differences to meet local regulations. The main differences among trims were features, interior appointments, and tech packages, not core propulsion.
In brief, the CSX’s propulsion is a Honda-sourced 2.0-liter i-VTEC inline-4 designed to deliver dependable daily performance and reasonable fuel economy in a compact Acura sedan.
Conclusion
The core answer remains: the Acura CSX uses a 2.0-liter inline-4 i-VTEC engine, paired with front-wheel drive, and is closely related to the Civic’s powertrain family. It emphasizes reliability and efficiency over high-end performance, aligning with the CSX’s role in Acura’s lineup during its Canadian market years.
Summary
Summary: The Acura CSX is powered by a 2.0-liter i-VTEC inline-4 engine, delivering about 155 horsepower and 139 lb-ft of torque, with a choice of a 5-speed manual or 5-speed automatic transmission, and it is shared with Honda’s Civic 2.0L family.
