After making its debut in 2004, the 6-Series returns for 2005 with no major changes. The 6-Series consists of two models: 645Ci coupe and 645CiC convertible. A 4.4L V8 engine producing 333-hp and 332 lb-ft of torque powers both models. This engine is capable of reaching 0-60 miles per hour in 5.5 seconds. Three six-speed transmission choices are available along with sport suspension and adaptive cruise control. The interior can be ordered with either dark or light birch appliques as well as heated front seats. The optional Sport package offers active steering, sport bucket seats, shadowline exterior trim, and 19-inch Alloy wheels with performance tires. Additional options include park distance control, a head-up display, and Sirius Satellite radio.
