Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2019-Present BMW 340i use?

The 2019-Present BMW 340i features an xDrive all-wheel-drive system as standard, with an optional rear-wheel-drive (sDrive) configuration. The xDrive system uses a multi-plate clutch to distribute torque between the front and rear axles, with a default 40:60 front-to-rear torque split for optimal handling.

What is the transmission type and gear ratio for the 340i?

The 340i is equipped with an 8-speed Steptronic Sport automatic transmission (ZF 8HP). The gear ratios are as follows: 1st (4.714), 2nd (3.143), 3rd (2.106), 4th (1.667), 5th (1.285), 6th (1.000), 7th (0.839), and 8th (0.667). The final drive ratio is 2.81 for xDrive models and 2.93 for sDrive models.

What is the maximum torque output of the 340i drivetrain?

The 340i's B58 3.0L inline-6 turbocharged engine produces a maximum torque of 369 lb-ft (500 Nm) at 1,520–4,500 rpm. This torque is efficiently transferred through the drivetrain to ensure responsive acceleration and dynamic performance.

How does the xDrive system enhance performance in the 340i?

The xDrive system in the 340i continuously monitors driving conditions and adjusts torque distribution between the front and rear axles. It can send up to 100% of torque to either axle, improving traction, stability, and cornering performance, especially in adverse weather conditions.

What maintenance is required for the 340i drivetrain?

Regular maintenance includes checking and replacing the transfer case fluid every 60,000 miles (96,000 km), inspecting the driveshaft and differential for wear, and ensuring proper lubrication of all drivetrain components. BMW recommends using only genuine BMW fluids and parts to maintain optimal performance and warranty coverage.
