The
F20C and
F22C1 are
inline-4 engines produced by
Honda. They are the only Honda 4-cylinder engines that are designed to sit
longitudinal for
rear wheel drive.
These engines are unrelated to the
F-series engines found in the mid 90s
Honda Accord and
Prelude. They share many properties with the
H-series. These engines, unlike most F-series engines, have two overhead cams, a VTEC system for both the intake and exhaust camshaft, Fiber-Reinforced Metal cylinder liners
,
molybdenum disulfide-coated piston skirts for reduced friction, and uses a timing chain.

- Stroke:
- Rod Length: 153 mm
- Rod/stroke ratio: 1.82
- Power: JDM 250 PS (183.88 kW) @ 8,300rpm & 22.2kgm (217.71 Nm) @ 7,500 rpm
- USDM 240 HP @ 8,300 rpm; 153 ft lb , 207 Nm @ 7,500 rpm
- Redline: 9000 rpm
- VTEC: 6100 rpm
The F20C was designed with high maximum rpm capability in mind, for increased power output; redline is at 9000 rpm, with VTEC engagement at 6000 rpm. Its relatively long stroke of 84mm results in a
mean piston speed of 4965 ft/m, 56.42 mph or 25m/s, higher than any other production car to date. Power output is at 8300 rpm in North America and Europe. The Japanese version, which has a higher compression ratio, is capable of at 8600 rpm. Honda's F20C Engine won a spot on
