Frequently Asked Questions

Find answers to common questions about torque specifications

What type of transmission is used in the 2000-2003 BMW Z8?

The 2000-2003 BMW Z8 is equipped with a 6-speed manual transmission (Getrag Type D) as standard. It features a rear-wheel-drive configuration with a 3.15:1 final drive ratio for optimal performance and handling.

What is the engine displacement and power output of the BMW Z8 drivetrain?

The BMW Z8 is powered by a 4.9-liter S62 V8 engine, producing 400 horsepower at 6,600 RPM and 369 lb-ft of torque at 3,800 RPM. This engine is paired with the manual transmission to deliver a 0-60 mph time of approximately 4.5 seconds.

What type of differential is used in the BMW Z8?

The BMW Z8 uses a limited-slip differential (LSD) with a 3.15:1 ratio. This differential enhances traction and stability during high-performance driving by distributing torque evenly between the rear wheels.

What is the recommended service interval for the drivetrain components?

BMW recommends inspecting the drivetrain components, including the transmission and differential, every 30,000 miles or 24 months, whichever comes first. Transmission fluid should be replaced every 60,000 miles, and differential fluid every 50,000 miles.

Can the BMW Z8 drivetrain handle aftermarket performance upgrades?

While the BMW Z8 drivetrain is robust, any aftermarket upgrades should be carefully selected and installed by a certified technician. Upgrades such as performance clutches or differentials may void the warranty if not approved by BMW. Always consult the official documentation before modifications.
