Three sport sedans and a sport touring wagon comprise BMW's mid-size cars for 2003. Sedans vary with the size and type of engine applied. In-line six-cylinder powertrains from the 3-Series drop into two of the 5-Series models -- the 2.5-liter six for 525i and 3.0-liter version for 530i. Top 540i sedan and 540i wagon carry the 4.4-liter V8 that runs up to 290 hp. All 5-Series cars provide the entire spectrum of BMW mechanical systems for performance and safety, including HPS air bags, Dynamic Stability Control (DSC), All Season Traction (AST) and anti-lock brakes (ABS). A moonroof has been added as standard equipment on six-cylinder models and HPS air bags reach to rear seats. For 540i with a six-speed manual transmission, a new sport package mounts spoilers front and rear, plus black side molding, M5 suspension components, 18-inch wheels and keen exhaust pipes.
