2012 Acura TSX Horsepower: The Definitive Owner's Playbook
The 2012 Acura TSX remains one of the most compelling used sport sedans on the market, combining precision handling, a refined interior, and peppy acceleration that punches above its price tag. At the heart of it all is the 2.4-liter i-VTEC inline-4 producing 201 horsepower — a figure that delivers genuinely fun driving dynamics without crossing into costly territory.
This guide breaks down every specification, real-world performance figure, upgrade path, and maintenance checklist you need to know. Whether you're a prospective buyer, current owner, or automotive enthusiast, this is your complete reference for the 2012 Acura TSX horsepower story.
Key Takeaways
- 2012 Acura TSX horsepower: 201 HP at 7,000 RPM and 170 lb-ft of torque at 4,900 RPM from the 2.4L i-VTEC inline-4 engine (K24Z7).
- Transmission options: Standard 5-speed automatic or available 6-speed manual; both deliver strong real-world acceleration.
- 0–60 mph time: Approximately 6.5 seconds with the 6-speed manual, slightly slower with the automatic (~7.0 seconds).
- EPA fuel economy: Up to 22 city / 31 highway MPG (automatic); 22 city / 29 highway (manual).
- Weight distribution: Near 60/40 front/rear bias with a MacPherson strut front and multi-link rear suspension for balanced handling.
- Known issues affecting performance: Carbon buildup on intake valves, idle control valve (ICV) problems, and timing chain wear at higher mileages.
2012 Acura TSX Engine Specifications
The 2012 Acura TSX is powered by Honda/Acura's well-regarded K24Z7 2.4-liter DOHC i-VTEC inline-4 engine. This is the same family of engines found in the Honda Civic Si, Acura ILX, and RDX, renowned for reliability and responsive power delivery.

How the K24Z7 Engine Works
The K24Z7 uses Acura's i-VTEC (intelligent Variable Valve Timing and Lift Electronic Control) system, which independently varies both valve timing and lift across the RPM range. Unlike older VTEC systems that "switch" abruptly, i-VTEC provides seamless transitions. The result is strong mid-range torque for everyday driving and a free-revving character above 5,000 RPM where peak horsepower lives.
The long 99mm stroke relative to the 87mm bore gives this engine excellent low-end and mid-range torque — a design choice that prioritizes real-world drivability over track-focused top-end power. This makes the TSX feel brisk in normal driving even though 201 HP isn't a staggering number on paper.
Real-World Performance Numbers
Official factory figures tell part of the story. Real-world testing and owner reports paint a fuller picture of what 201 horsepower feels like in a car that tips the scales at roughly 3,200 pounds.
Acceleration Benchmarks
- 0–60 mph: 6.4–6.8 seconds (manual), ~7.0 seconds (automatic) — Car and Driver measured 6.4 sec in a 2012 TSX-S
- 0–100 km/h: ~6.9 seconds (manual)
- Quarter mile: ~15.0 seconds at ~94 mph
- 60–100 mph (passing): ~5.5 seconds in 5th gear, quicker in manual with downshifts
- Top speed (electronically limited): ~130 mph
Driving Impressions by Scenario
- City driving: Strong off-the-line response thanks to 170 lb-ft of torque arriving early. The engine is smooth and quiet below 3,000 RPM.
- Highway merging: Adequate but requires deliberate downshifting in the automatic. The 6-speed manual is noticeably more confident here.
- canyon runs: The chassis shines here. Power-to-weight ratio is favorable, and the steering-ratio shifter (on manual models) enhances driver engagement.
- Full-throttle passes: Beyond 4,500 RPM the K24Z7 comes alive. Rev-matching on the manual produces satisfying acceleration through the gears.
