Ford 6.8L Modular V-10

Ford 6.8L Triton V-10 Specs, Power Ratings, History, & Comparisons

Ford introduced the 6.8L Triton V-10 for the 1999 model year as a replacement for the dated, but well respected 7.5L V-8 (460 CID). Whereas the 7.5L produced up to 245 horsepower and 395 lb-ft of torque during its service life, the 6.8L V-10 was introduced with 305 horsepower and 420 lb-ft of torque. It would receive a small performance boost for the 2000 model year, and a 3 valve version of the engine was introduced for the 2005 model year, bumping horsepower to 362 HP and torque to 457 lb-ft in the Ford F-Series. The 6.8L V-10 remains in service today, however it was retired from the Ford Super Duty platform (non-chassis cab) following the 2010 model year. The 6.2L V-8 replaced the V-10 option in all F-250/F-350 applications, becoming the standard engine the same year that Ford rolled out its 6.7L Power Stroke turbodiesel.

The 6.8L V-10 belongs to the Ford Modular engine family and thus shares commonalities with the 4.6L and 5.4L V-8 engines. In fact, the 6.8L and 5.4L share an identical bore diameter and stroke length; the V-10 simply has two additional cylinders. Like the other Modular engines, the 6.8L is recognized under the "Triton" trademark. The 6.8L V-10 competed against three of Ford's Power Stroke offerings; the 7.3L, 6.0L, and 6.4L diesels. While the diesel displayed superior torque characteristics, the V-10's horsepower rating proved favorable against all three engines.

The 6.8L V-10 is well known for its respectable power, however this comes at the cost of unfavorable fuel economy. In a nutshell, it is difficult to escape the reality that a large displacement engine will inherently consume more fuel. The 6.8L remains available in select chassis cab, Econoline, and medium duty applications, although rumors suggest that the engine will be replaced altogether in favor of a more efficient option. In reality, the 6.8L relies on 1999 technology and is approaching a 20 year service life. Currently, the engine serves as an economical alternative to more expensive diesel options.

Ford's V-10 faired well against its competition in the 3/4 and 1 ton gas engine segment, producing equal or more power/torque than engines of much larger displacement. This includes Chrysler's 8.0L V-10 (310 hp/450 lb-ft) and GM's 8.1L V-8 (340 hp/455 lb-ft). The lower displacement of the 6.8L theoretically grants it an advantage with regard to fuel economy, amongst other benefits against larger displacement engines.
