2021 BMW X5 PHEV
May 10 2021,
As BMW moves towards a future of electrification, the steps along the way bridge the gap from the combustion-engined vehicles most of us drive to pure electrification. One of those steps is the plug-in hybrid electric vehicle (PHEV), a category of vehicle that could be described as the ‘best of both worlds’ from the current market and to where the future of car buying lies. In the case of the BMW X5 xDrive45e, BMW moves their midsize SUV forward with a six-cylinder engine shared with the 40i models, an electric motor between the engine and the 8-speed transmission, and a dedicated electric range of 50km. The total combined output for this system is 389 horsepower and 443lb/ft of torque.
The critical difference between a hybrid and a PHEV is the dedicated electric driving range. Hybrids have a small electrical capacity that is optimized for fuel efficiency. For PHEVs, they feature a much larger battery pack and the ability to charge up by connecting to any power outlet. For the X5 xDrive45e, a 24kWh lithium-ion battery is housed underneath the trunk floor. Like any other electrified vehicle, the X5 xDrive45e has regenerative brakes that feed a small amount of electricity into the battery pack when coasting or when the brakes are applied. Some pure electric vehicles feature a ‘one-pedal driving experience’ where the regenerative brakes are so strong, they can bring the vehicle to a dead stop without ever using the brake pads and rotors. BMW avoided this approach with their X5 xDrive45e as the braking experience and one-pedal attitude can be an unnatural for drivers. At the end of the day, BMW still wanted their X5 xDrive45e to drive as well as any other BMW product.
The X5 xDrive45e has a variety of different driving modes selected by the button layout beside the crystal gear-shifter. These modes include: Sport, Hybrid, Electric and Battery Hold mode. The first three modes a relatively straightforward. Each of these models prioritizes the power delivery of the electric system and the straight-six gasoline engine in varying levels of output. The Sport mode always has the engine running with the electric motor giving XtraBoost capacity at the top of the rev range where an additional 40 horsepower is unlaced in 10-second surges. Hybrid modes uses both systems to maximize efficiency and response. Then Electric mode will lock in the electrical fore of the X5 xDrive45e to use up all its charge before igniting the engine. Battery Hold mode retains a selected level of battery charge set that the energy has be preserved for later on. For example, when driving on a highway, the electrical charge will be used up quicker so if the Battery Hold eDrive setting is engaged, this battery power can be used once off of the highway and driving around at a low speed to reduce fuel consumption.
As you can tell, there is a lot to discover with the new 2021 BMW X5 xDrive45e. To learn more about this PHEV, head over to Calgary BMW on Heritage Meadows Road where the team will help further explain the advantages of the 2021 BMW X5 xDrive45e!
