The Honda S2000 uses two generations of high-revving inline-four engines: the AP1 models run the 2.0-liter F20C, while the AP2 models switch to the larger 2.2-liter F22C1. Both are naturally aspirated DOHC VTEC units designed for spirited, high-rev performance.
Two generations, two engines
The S2000, launched in 1999 as a lightweight roadster focused on driver engagement, initially arrived with a compact 2.0-liter powerplant. In 2004, Honda refreshed the lineup with a larger displacement engine to broaden the torque curve while preserving the car’s characteristic high-rev nature.
AP1 — F20C 2.0-liter inline-four
The first-generation S2000 (AP1) used Honda’s F20C engine, a 2.0-liter DOHC i-VTEC four-cylinder designed for peak performance at high engine speeds. It helped establish the model’s reputation for a thrilling, race-inspired driving experience.
Key specs:
- Displacement: 2.0 L (1997 cc)
- Configuration: Inline-4, DOHC, i-VTEC
- Redline: ~9,000 rpm
- Power: ~240 hp (US); up to ~250 hp (JDM)
- Torque: ~153 lb-ft (207 Nm)
AP1 S2000s are celebrated for their precision shifting, ultra-high rev limit, and a pure, communicative throttle response that appealed to driving enthusiasts.
AP2 — F22C1 2.2-liter inline-four
The 2004 refresh (AP2) swapped in the F22C1 engine, increasing displacement to 2.2 liters. The upgrade aimed to deliver more mid-range torque while keeping the rev-happy character that defined the car’s appeal, albeit with a slightly lower redline than the AP1.
Key specs:
- Displacement: 2.2 L (2237 cc)
- Configuration: Inline-4, DOHC, i-VTEC
- Redline: ~8,000 rpm
- Power: ~237 hp (177 kW)
- Torque: ~162 lb-ft (220 Nm)
AP2 engines offered stronger low- to mid-range torque and were paired with subtle chassis refinements, maintaining the S2000’s spirited driving dynamics across markets.
What engine is in a Honda S2000?
In concise terms, the S2000’s engine evolved from the 2.0-liter F20C in AP1 to the 2.2-liter F22C1 in AP2. Both are naturally aspirated inline-four engines equipped with Honda’s VTEC technology, delivering high-rev performance with a distinctive exhaust note.
Summary
The Honda S2000 is powered by two generations of high-revving, naturally aspirated inline-four engines: the F20C 2.0L in AP1 and the F22C1 2.2L in AP2, both using VTEC to balance performance and responsiveness in a lightweight roadster.
