BMW i4 Range

The i4 has an 83.9 kWh battery pack with a WLTP-claimed range of 590 km. The electric motor has an output of 335 bhp and 430 Nm. With this setup, the i4 can go from 0 to 100 km/h in about 5.7 seconds, highlighting its performance capabilities. However, several factors can affect its range: 

• Driving Style: Driving style plays a critical role in conserving energy. It is essential to prioritise smooth acceleration and gentle braking, as aggressive driving with rapid and hard braking can quickly deplete the battery. To maximise range, the i4's regenerative braking system can recover some energy by releasing the accelerator early when slowing down. However, maintaining a consistent and moderate driving style is the most efficient method to extend the range.

• Speed: Driving at high speeds, particularly on highways, can significantly diminish the range of the BMW i4 electric vehicle. Conserving energy and maximising distance can be achieved by maintaining a steady and moderate speed, as higher speeds consume more power, similar to traditional fuel usage.

• Cabin Preconditioning: Preconditioning the cabin of the i4 before driving can save battery power and preserve the vehicle's driving range by using power from the grid instead of the battery. This is especially important during extreme weather conditions.

• Traffic Conditions: Routes with heavy stop-and-go traffic or frequent stoplights can negatively affect range. Frequent braking and acceleration consume more energy than steady driving on open roads. Whenever possible, plan routes with less congestion to improve efficiency.

• Vehicle Maintenance: Regular maintenance of the BMW i4 is essential for optimal performance and range. Proper tyre pressure, wheel alignment, and battery health checks can prevent unnecessary energy loss. A well-maintained vehicle operates more efficiently, contributing to extended mileage.

• Wind: Headwinds can significantly impact the range of electric cars as they create resistance, requiring the engine to work harder to overcome this effect. Electric vehicles with the most extended range are typically characterised by the lowest air resistance or Cw value, also known as the air Resistance Coefficient.

• Load: The heavier the cargo on board, the greater the strain on the engine. Although there is no definitive data on the impact, carrying more passengers and luggage certainly reduces the efficiency of an EV. Therefore, it is advisable to avoid unnecessarily transporting unused items.
