Does the 09 TSX have VTEC?
The 2009 Honda TSX does feature VTEC technology. It uses Honda’s i-VTEC on its 2.4-liter inline-four engine, providing variable valve timing and lift to balance performance with efficiency.
VTEC in the 2009 TSX: what it means
In the 2009 TSX, the VTEC system is part of Honda’s K-series engine family. The vehicle relies on i-VTEC to vary valve timing and lift on the engine, improving power at higher RPMs while preserving good low-end torque and fuel economy. This setup is a core part of the TSX’s performance characteristics and distinguishes it from non-VTEC compact sedans.
Engine specifics
Core specifications and features of the VTEC-equipped powertrain in the 2009 TSX include:
- Engine: 2.4-liter inline-4, K24Z3, with i-VTEC
- Power and torque: approximately 201 horsepower and 172 lb-ft of torque
- Valvetrain: dual overhead cam (DOHC) with i-VTEC on the intake cam, providing variable lift and timing
- Transmissions: available with a 6-speed manual or a 5-speed automatic, depending on trim and market
In short, the 2009 TSX integrates i-VTEC to optimize breathing at different speeds, contributing to its blend of responsive performance and everyday drivability.
Why this matters for drivers
For owners and enthusiasts, the presence of i-VTEC means the engine can switch to a more aggressive cam profile at higher revs while maintaining smoother manners at lower speeds. This translates to stronger acceleration characteristics in the mid-to-high RPM range and improved fuel efficiency when the engine operates in its lower-RPM, efficiency-focused regime.
Summary
The 2009 Honda TSX does have VTEC technology, specifically the i-VTEC system on its 2.4-liter K-series engine. This setup provides a balance of performance and efficiency, with several transmission choices that align with buyer preferences. Overall, VTEC is a defining feature of the TSX’s powertrain in that model year.
