Ford's All New 4.6 Liter SOHC V-8 Engine for the Lincoln Town Car 910680

Ford is introducing the first high volume domestically designed and produced overhead camshaft V-8 engine As the first entry of a family of V-8 engines, the 4.6L 2 valve per cylinder engine was created to replace Ford's work-horse small block V-8 family of pushrod engines. That family of engines was first produced in 1962 in a 221 cu. in. version and have since evolved into the 302 cu. in. (5.0L) engine which previously powered the Town Car.
Design goals of the engine family were:
  • Higher horsepower output combined with reduced engine displacement
  • Improved fuel efficiency and reduced emissions
  • Reduced noise and vibration
  • Advanced technology
  • Precision manufacturing
  • Improved quality and durability
Program Execution was accomplished by extensive use of teamwork processes, including Cross Functional Teams (CFTs) among Design Engineering, Manufacturing Engineering, Suppliers, Purchasing and Vehicle Engineering.
In the Lincoln Town Car, the engine delivers 210 hp @ 4600 rpm and 270 ft-lbs @ 3400 rpm, delivering 90% of its peak torque from 1200 rpm through the normal operating range. The vehicle has achieved improved performance feel as indicated by a 1.5 second reduction in 0-60 mph time while maintaining competitive fuel economy.
