Thanks mainly to its domination of common-rail diesel technology, Robert Bosch has moved past Visteon to become the world's second-largest supplier.
Bosch's automotive sales rose from $19.1 billion in 1999 to $20.55 billion in 2000, overtaking Visteon.
Delphi reported sales of $29.1 billion in 2000, and Visteon $19.5 billion.
Bosch said its growth was mainly due to expanding diesel injection sales.
Bosch has been the sole supplier of common-rail diesel systems -a technology much sought-after by European carmakers.
Reported revenue was also boosted by first-time consolidation of Bosch Automotive Systems in Japan.
When calculated in euros, Bosch's automotive sales grew 13 percent, compared to 7.6 percent in US dollar terms. Sales in dollars were pulled down by the depreciation of the German mark from an average 1.84 to the dollar in 1999 to 2.12 to the dollar in 2000.
