Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2014-2016 BMW 435i use?

The 2014-2016 BMW 435i features a rear-wheel-drive (RWD) system as standard, with an optional xDrive all-wheel-drive (AWD) system. The drivetrain is paired with an 8-speed automatic transmission (ZF 8HP) or a 6-speed manual transmission (Getrag GS6-45BZ).

What is the torque rating of the 435i's drivetrain?

The N55 3.0L TwinPower Turbo inline-6 engine in the 435i produces a maximum torque of 300 lb-ft (406 Nm) at 1,200-5,000 rpm. This torque is transmitted through the drivetrain to the rear or all four wheels, depending on the configuration.

How often should the drivetrain components be inspected?

BMW recommends inspecting drivetrain components, including the driveshaft, differential, and axles, every 30,000 miles or during routine maintenance. Pay special attention to fluid levels, wear on universal joints, and any unusual noises or vibrations.

What type of differential is used in the 435i?

The 2014-2016 BMW 435i uses an open differential as standard. However, the optional M Sport package includes a limited-slip differential (LSD) for improved traction and handling during high-performance driving.

Can the drivetrain handle performance modifications?

The N55 engine and drivetrain in the 435i are robust and can handle moderate performance upgrades, such as ECU tuning and bolt-on modifications. However, excessive power increases (beyond 400 hp) may require reinforced drivetrain components, such as upgraded axles or a stronger differential.
