Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2005-2011 BMW 335i use?

The 2005-2011 BMW 335i is equipped with a rear-wheel-drive (RWD) system as standard, with an optional xDrive all-wheel-drive (AWD) system available on certain models. The drivetrain includes a 6-speed manual or 6-speed automatic transmission (6HP19/6HP21), depending on the configuration.

What is the torque rating of the 335i's drivetrain components?

The N54 and N55 engines in the 2005-2011 BMW 335i produce a maximum torque of 300 lb-ft (406 Nm) at 1,400-5,000 RPM. The drivetrain components, including the driveshaft and differential, are designed to handle this torque output efficiently.

How often should the differential fluid be replaced?

BMW recommends replacing the differential fluid every 60,000 miles (96,000 km) under normal driving conditions. For high-performance or heavy-duty use, such as frequent towing or track driving, the interval should be reduced to 30,000 miles (48,000 km). Use only BMW-approved synthetic gear oil (SAE 75W-90).

What is the gear ratio of the 335i's differential?

The standard final drive ratio for the 2005-2011 BMW 335i is 3.08:1 for automatic transmission models and 3.46:1 for manual transmission models. The xDrive AWD models may have slightly different ratios depending on the configuration.

Can the 335i's drivetrain handle aftermarket performance upgrades?

The drivetrain components of the 335i are robust and can handle moderate performance upgrades, such as a Stage 1 tune. However, for significant power increases (e.g., Stage 2 or higher), upgrading the clutch (for manual models), driveshaft, and differential is recommended to ensure reliability and prevent premature wear.
