Welcome to the WOT universe. At WOT, the engine is an obsession. All our developments are done based on engine code. B58H is the internal engine reference for your BMW X5 45e. Let us sublimate your engine thanks to homologated engine reprogramming.

Vehicles other than the BMW X5 featured on this page also use the B58H.

The BMW B58 hybrid engine

“Driving pleasure” is far more than just a motto for BMW; it is the cornerstone of its success as a company.

From engine placement to agile suspension systems, the vehicles designed by this German manufacturer reflect its excellence in the competitive premium automotive market.

In Europe, the SUV market has grown dramatically in recent years, mainly due to their versatility. With its latest X5 model, BMW has had to meet European expectations by also offering a hybrid version, very popular with companies due to of its reduced CO2 emissions.

This provides significant fiscal benefits in terms of deductibility or fringe benefits. BMW’s strategic partnership with Toyota paved the way for remarkably high-performing hybrid powertrains, embodied in the 45e model. It is the only 6-cylinder hybrid engine to emit less than 49g of CO2 at the time of launching. It is precisely this environmental prowess that has earned this vehicle its place among our fleet of test and courtesy vehicles.

Front view of

While most manufacturers opt for the transition to hybrid by settling for a highly electrified 4-cylinder engine, BMW has chosen a different path. For BMW, abandoning the venerable in-line 6-cylinder engine that made it famous was out of the question. The Bavarian engineers therefore took the bold decision to reduce its power while combining it with a generously sized battery pack (24 kWh). This hybrid engine is called the 45e and is based on the now well-known B58 which, in this configuration, develops 394 hp for a torque of 600 Nm. A veritable technological feat.

Little anecdote

By way of an anecdote, the X5 45e sold in the USA has the same battery as its European counterpart, but is electronically capped to 17.06 kWh capacity instead of the 21.6 kWh offered in Europe. A choice that is difficult to understand and likely explains abandoning the 45e version in the United States in favor of the 40i version without hybridization, which is less heavy and less costly.

The development process

We select the vehicle which combines the most significant criteria contributing to pollution, in particular: consumption, weight, air resistance (drag coefficient) and type of transmission. For this B58H engine, we opted for the BMW X5 45e model. If the vehicle successfully passes the numerous pollution tests, the official verification body can logically conclude that the other, less polluting models in the range will also obtain positive results. This is why, within WOT, such importance is given to the engine code.

What about the warranty?

At WOT, we invest heavily in research and development to provide you with an experience where performance and reliability go hand in hand. However, it is possible that during a routine inspection, the manufacturer has detected that your vehicle has undergone modifications. Even if the improvements made by WOT are homologated, this detection can lead to the loss of the factory warranty.

For this reason we have created an additional motor warranty, specifically designed to meet your highest demands.
