What is the differance between Volvo's L1 (B5) Engine Code and M1 (B5) Engine Code?

The main difference between Volvo's L1 (B5) and M1 (B5) engine codes lies in their drivetrain configuration:

L1 (B5) Engine Code:

This refers to a B5 engine with front-wheel drive (FWD) configuration.

M1 (B5) Engine Code:

This denotes a B5 engine with all-wheel drive (AWD) configuration.

Both L1 and M1 engine codes use the B5 powertrain, which consists of:

A 2.0-liter turbocharged four-cylinder gasoline engine

A 48-volt mild hybrid system

The B5 engine typically produces around 247 horsepower and 258 lb-ft of torque. The mild hybrid system includes a lithium-ion battery pack and a 13-horsepower integrated starter generator, which helps improve fuel efficiency and provides smoother acceleration.

The key distinction between these two engine codes is the drivetrain layout, with L1 being front-wheel drive and M1 being all-wheel drive. This difference can affect factors such as traction, handling, and potentially fuel economy, depending on the specific vehicle model and driving conditions.

It's worth noting that the availability of FWD or AWD options may vary depending on the specific Volvo model and market. For example, some SUV models like the XC60 and XC90 may come standard with AWD, while sedans like the S60 might offer both FWD and AWD options.
