Ford SHO V6 engine

Encyclopedia : F : FO : FOR : Ford SHO V6 engine


Ford Motor Company worked with Yamaha Motor Corporation to develop a compact 60° DOHC V6 engine for transverse application. This V6 was to power a mid-engine sports car in the early 1990s, but that project (known internally as GN34) was cancelled. The company decided to place the engine, dubbed Super High Output (or SHO) into the front wheel drive Ford Taurus sedan.

The SHO engines share a common bellhousing pattern with the following Ford engines: the 2.3/2.5 L FWD HSC I4, the 3.0L FWD/RWD Vulcan V6, and the 3.8 FWD Canadian Essex V6.

The SHO V6 was a high-tech design at its debut in 1989. A 3.0L (2986 cc), it was an iron block, aluminum head 24-valve DOHC engine with an innovative variable length intake manifold. Its oversquare design, which sported an 89 mm bore and 80 mm stroke, gave the high-revving engine an output of 220 bhp (164 kW) and 200 ft·lbf of torque (271 Nm) at the flywheel.

3.2 L

From 1993 to 1995, Ford mated a larger 3.2L (3200 cc) version of the 3.0L V6 to an automatic transmission. This new engine, while retaining the same 80 mm stroke of its 3.0L brother, sported a larger 92 mm bore that helped raise output to 220 bhp (164 kW) and 215 ft·lb of torque (298 Nm) at the flywheel.

In 1996, Ford replaced this engine with a 3.4L V8 and automatic transmission.
