International Truck and Engine Corporation (Navistar International Corporation) manufactured turbocharged diesel engines for Ford Motor Company starting in the early 1990s. These engines were utilised in the F-series trucks and Ford Econoline vans under the moniker Power Stroke. In 2001, Ford Motor Company and Navistar formed a new joint venture, Blue Diamond Truck Co. LLC.

1985 to 1987 Ford Ranger

Mitsubishi supplied turbo diesel engines to Ford for the Ranger pickup for three years. The engine was a 2.3L that produced 86 horsepower at 4,200rpm, with 60.8kg.-ft. of torque at 2,000rpm. The engine's bore was 3.59 inches by 3.54 inches, with a compression ratio of 21:1.

1995 to 2001

The Navistar International 7.3L 235-horsepower engine with 227kg.-ft. of torque was the meat-and-potatoes engine for the F-series Ford diesels. This engine was the first 7.3L turbocharged diesel to squeeze out enough performance to satisfy owners of the heavy-duty F-series vehicles. The Turbo diesel package remained the same until 2002, when additional performance was called for. There were independent engine packages for manual transmission (275hp) and automatic transmission (250hp) while still utilising the 7.3L.


The Navistar 7.3L 250-horsepower engine with 238kg.-ft. of torque lasted only one year in Ford trucks. With the new federal emission standards dictating better fuel economy and cleaner-burning diesels, the Blue Diamond Truck Company (Navistar and Ford) worked together toward compliance.


The Navistar 7.3L 210-horsepower with 236kg.-ft. of torque lasted for just part of the 2003 year. Ford and Navistar introduced an additional diesel engine the same year to comply with the more stringent federal emissions standards.

2003 to 2007

The Navistar 6.0L 325-horsepower engine at 3,300rpm with 259kg.-ft. @ 2,000 cast-iron block and heads were made for Ford F-series heavy-duty trucks. Smaller than the 7.3L, with more horsepower and torque twist for the highway, this engine featured a much better weight-to-output ratio. This Power Stroke engine was compliant with the new federal emissions standards at the time.

2008 to 2010

The Navistar 6.4L V8 engine produced 350 horsepower at 3,000rpm with 295kg.-ft. of torque at 2,000rpm and was the primary workhorse diesel for the Ford Motor Company's Power Stroke. The Ford heavy-duty truck series and the International Classes 3 through 7 were a success for Blue Diamond.

Ford's 2011 6.7L

Ford designed, engineered and manufactured a biodiesel composite of compacted graphite iron (CGI) block with aluminium heads that produces 390 horsepower at 2,800rpm with 333kg.-ft. of torque at 1,600rpm from a 6.7L turbocharged diesel V8 engine.
