The term High Speed Diesel refers to the engine revs, not the vehicle speed. All passenger car diesel engines have always been High Speed Diesels.White Exec wrote:I was a regular reader of Diesel Car magazine in the late 80s and the 90s. Dean is right, the appearance of the XUD was a (possibly the) turning point in passenger car and small diesel power units. It was dubbed a "high speed diesel", and not without reason: the BX19 could reach 100mph, and with extraordinary economy. Another milestone was BMW's 2.5td, a six-cylinder, and this remained a benchmark for several years.
The BMW 2.5 is a great engine as long as you don't require any torque. Sounds good, but outclassed by the Mercedes OM605 and OM606.
