2004-2008 BMW 5-Series: Technical Specifications

BMW's 5-Series sedan comes with quite a choice of powertrains. A 184-horsepower 2.5-liter inline six-cylinder engine goes into the 2004-05 525i, mated to six-speed manual or six-speed automatic transmission. The 530i holds a 225-horsepower 3.0-liter six-cylinder engine, with the same transmission choices plus a sequential manual transmission (SMT). A 4.4-liter V8 rated at 325 horsepower goes into the 545i, with a six-speed manual or SMT, or a five-speed automatic. For 2006, a 215-hp 3.0-liter six replaced the 2.5-liter in the 525i, and the 3.0 in the 530i gained 30 horsepower. A new 4.8-liter V8 went into the 550i (formerly 545i). BMW also launched an M5 sedan with a V10 engine and seven-speed SMT. A Power button could switch the V10 between 400 and 500 horsepower. New 6-cylinder engines marked the 2008 BMW 5-Series. 528i and all-wheel-drive 528xi sedans replaced the 525i and 525xi. 535i sedan and AWD 535xi sedans and wagons replaced the 530i and 530xi. The 528 and 535 got a new 3.0-liter 6-cylinder engine; it made 230 horsepower in 528s, 300 in the turbocharged 535s .
