Engines
Originally, the Range Rover was fitted with a detuned 135 hp (101 kW) version of the Buick-derived Rover V8 engine. The 3,528 cc (3.5 L; 215.3 cu in) engine was increased to a displacement of 3,947 cc (3.9 L; 240.9 cu in) for the 1990 model year, and 4,197 cc (4.2 L; 256.1 cu in) in 1992.
Petrol-fuelled Range Rovers were fitted with carburettors until 1986, when they were replaced by Lucas electronic fuel injection, improving both performance and fuel economy. The Lucas injection system continued to evolve over the next several years, culminating in the 1990 to 1995 Lucas 14CUX. Some export markets retained carburettors, with the original Zenith/Stromberg manufactured units being replaced by Skinners Union (SU)-manufactured items.
From 1979 onwards, Land Rover collaborated with Perkins on Project Iceberg, an effort to develop a diesel version of the Range Rover's 3.5 litre V8 engine. Both naturally aspirated and turbocharged versions were built, but the all-alloy engine blocks failed under the much greater pressures involved in diesel operation. The project was, therefore, abandoned. The effort to strengthen the Rover V8 for diesel operation was not, however, completely wasted; the 4.2 litre petrol variant of the engine used crankshaft castings developed in the Iceberg project.
Because of the Iceberg failure, it was not until 1986 that Range Rovers gained diesel engines from the factory. The more efficient 2,393 cc (2.4 L; 146.0 cu in) inline-four VM diesel from Italy was made available as an option for the heavily taxed European market as the 'Turbo D' model, and were increased to 2,499 cc (2.5 L; 152.5 cu in) in 1989. The VM engines were highly advanced and refined diesel engines for their time but were received poorly by the UK press, who tended to compare their performance to the V8 models. To counter these criticisms Land Rover used a Turbo D Range Rover to set several speed and endurance records for diesel vehicles during 1987, including a continuous run over 24 hours at over 100 mph (160 km/h). The VM were replaced by Land Rover's own 200Tdi turbocharged diesel engine in 1992. and 300Tdi at the end of 1994.

Famous quotes containing the word engines:
“America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.”
—Thomas McGuane (b. 1939)
