Introduction to the BMW B58 Engine

A brief history

The BMW B58 engine is an inline-six engine introduced in 2015 as a successor to the highly acclaimed N55 engine. This powerplant was designed to meet the demands of modern driving with improved performance, efficiency, and emissions. Developed by BMW's engine division, the B58 engine has become a staple of the brand's lineup, powering several of their high-performance models and earning accolades from enthusiasts and critics alike.

Technical specifications

The B58 is a 3.0-liter, inline-six, single-turbocharged engine with direct fuel injection, variable valve timing, and lift control (Double VANOS and Valvetronic). With a compression ratio of 11.0:1, the engine can produce impressive power and torque figures while maintaining efficiency and complying with stringent emissions regulations.

Features of the BMW B58 Engine

Integrated exhaust manifold

One of the most significant innovations of the B58 engine is the integrated exhaust manifold. This design allows for the exhaust gases to be directed straight into the turbocharger, reducing turbo lag and improving throttle response. The integrated manifold also enhances heat management, increasing efficiency and reducing emissions.

Water-to-air intercooler

The B58 engine utilizes a water-to-air intercooler, which is more efficient than traditional air-to-air intercoolers. This design allows for a reduction in turbo lag and improved performance, particularly during spirited driving or under heavy load.

Twin-scroll turbocharger

A key feature of the B58 engine is its twin-scroll turbocharger. This design allows for improved efficiency, with separate exhaust gas channels for each pair of cylinders. The result is quicker spooling, increased power, and improved throttle response.

Direct fuel injection

The B58 engine uses direct fuel injection, which provides more precise fuel delivery and improved combustion efficiency. This technology allows the engine to achieve better performance, fuel economy, and emissions.

Variable valve timing and lift

The B58 engine employs BMW's Double VANOS and Valvetronic technologies, which provide variable valve timing and lift control. This allows the engine to optimize performance across a wide range of driving conditions and ensures smooth, efficient operation.

Efficient cooling system

The B58 engine features a sophisticated cooling system, which includes an integrated water-to-air intercooler and an additional water pump for turbocharger cooling. This efficient cooling system helps manage heat and ensures the engine maintains optimal performance, even under demanding conditions.
