2006 NY Auto Show
The X5 continues in the same three models: X5 3.0i, powered by BMW's legendary inline 6-cylinder engine; X5 4.4i, with the 4.4-liter V8; and X5 4.8is, the flagship model that elevates the X5 to new heights of performance, handling and luxury. Of the three models, only the X5 3.0i has always been powered by the same engine: a legendary 225-horsepower inline 6-cylinder unit that provides this most accessibly priced X5 with smooth, willing and sonorous performance.
Alone among the X5 models, the 3.0i is available with a manual transmission. It is a 6-speed, and is standard equipment; optional is a 5-speed version of BMW STEPTRONIC automatic transmission, with Normal, Sport or Manual operating modes. In the Manual mode, the driver effects shifts by tipping the shift lever forward or rearward.
With its Valvetronic V8 engine, the X5 4.4i delivers 315 hp. The X5 4.8is employs a larger bore and stroke to obtain a displacement of 4.8 liters. In turn, this means even greater power and torque: 355 hp, and 360 lb-ft. of torque vs. the 4.4i's 324 lb-ft. So motivated, the 4.8is model reaches 60 mph from a standstill in just 5.9 seconds.
