Ford Motor Company will introduce a new six-litre V-8 diesel engine and a heavy-duty five-speed automatic transmission for its F-series Super Duty pickup and Excursion sport-utility vehicle, beginning in early 2003.
The new, more powerful, cleaner diesel engine and transmission will combine to develop what Ford claims is a best-in-class 325 horsepower at 3,300 rpm and 550 foot-pounds of torque at 2,000 rpm.
The new diesel will offer up to 10% better fuel economy and 20% lower emissions. The engine also has reduced noise levels and has improved speech intelligibility while driving by more than 20%.
“Truck customers are demanding more power, better NVH and increased fuel economy,” said Ford powertrains vice-president Dave Szczupak.
The Power Stroke six-litre V8 engine is a direct injection, 32-valve diesel with an all-new cast-iron block and cylinder heads. It has a single, block-mounted camshaft in a compact over-head valve (OHV) design, with hydraulic-valve lash adjustment.
