The arrival of the new iX3 represents the latest stage in BMW group’s electrification strategy.This is the first time a pure electric drive system has been combined with the BMW X’s rugged, versatile and roomy, comfortable and iconic sporting capabilities.At the same time, the iX3 is also the first car with the fifth-generation eDrive electric drive system developed and produced by BMW itself.It is highly integrated, does not contain any rare earth materials and is highly efficient.The cobalt and lithium used in the power system come only from reliable suppliers.

The shape ratio of the iX3 is roughly the same as that of the internal-combustion powered X3, but through a specially designed front/rear guard bar, mostly enclosed double-kidney grille, and a newly developed low-wind resistance light alloy wheel hub.

Aerodynamic effects are optimized to have a particularly low wind drag coefficient of 0.29 CD (the same as X3).Since the cooling requirement of pure electric power is not as great as that of internal combustion power, the active double-kidney grid is specially equipped with a 10-stage on function to accurately control the temperature.The new aerodynamic hub features unique plastic inserts that reduce drag coefficient by about 5% and improve efficiency by about 10 km (WLTP) range.The hub metal base can be painted in different colors, and you can choose a matte or polished surface, just like a traditional hub.The appearance of all plastic inserts can be customized to a specified gloss, finish, and pattern.
BMW’s fifth-generation eDrive technology in the iX3 incorporates an electric motor, 400 volts of power electronics and a single-speed gearbox in the same housing.

A highly integrated electric drive system architecture significantly reduces the amount of space required for installation and the weight of components relative to the power generated.About 30% more power density compared to the eDrive technology used in BMW’s existing electrified models.The fifth generation eDrive has made significant progress in performance characteristics, range, weight, required installation space and flexibility.The power system includes a more optimized electric motor (up to 17,000 RPM), power electronic control and charging system.

As well as a high-voltage battery, the new iX3 has a maximum output power of 286hp(210kW) and a maximum torque of 400Nm.0-100km/h acceleration in just 6.8 seconds (petrol powered X3xDrive30i in 6.4 seconds) is limited to a maximum speed of 180km/h.IX3 is widely used for secondary recovery of raw materials in the manufacture of aluminum castings and thermoplastics.The innovative design of electric motors and the full use of renewable energy in manufacturing processes, including high-voltage batteries, without reliance on rare earths have had a positive impact on the car’s environmental footprint.

So, more see iX3 due to not use current of permanent magnet synchronous electric motors, but the battery iron type motor (Currentexcitedsynchronousmotor), so differently by different current, pulse magnetic induction.Therefore, driving will find that the performance characteristics of different driving modes will be significantly different.Therefore, BMW I has retained the three driving modes of the internal-combustion powered model, including sport, comfort and energy-saving PRO.The electric motor of iX3 works on the principle of current induction synchronous motor, so it is significantly different from other high-priced electric vehicles.The rotor is excited not by a fixed permanent magnet but by an electrical feed (electromagnet).
This design allows the manufacture of electric motors without the need for the rare earths needed for permanent magnetic components.Instead of a balanced front and rear 5050, the iX3 has a mid-engine/rear-wheel drive front 43% of the sports car;The latter 57%, and there is no large weight in the front, so it has a completely different handling flexibility than X3.The iX3 features a unique rear-wheel drive subframe and a custom integrated chassis, all designed to meet the specific needs of the pure ev concept.It includes the instantaneous power of the electric motor and the special suspension adjustment of the series, as well as the CONTINUOUS anti-skid control system of ARB.

Provides agile handling, excellent directional stability and maximum traction for use in inclement weather conditions and on roads with poor grip.In addition, the kinetic energy recovery system of iX3 can adaptively adjust the recovery intensity according to the road conditions detected by the navigation system and driving assistance system sensors.For example, when approaching an intersection, a speed limit section or a vehicle in the front is in the way, the recovery efficiency and deceleration effect will be fully enhanced to increase the energy stored in the high-voltage battery;On open roads, the city immediately activates the taxi function every time a driver takes his foot off the accelerator pedal to improve efficiency and comfort.
If the route guidance function of the navigation system is not started, the driving situation will be adjusted.For example, turning on the direction light during taxi will immediately start the kinetic energy recovery operation.The adaptive kinetic energy recovery mechanism of iX3 can be activated when the gear position is selected at D.When switching to The B gear, it will always maintain a large kinetic energy recovery intensity, and release the acceleration pedal, which can be highly felt, into a unique single-pedal driving mode.In addition, driving can also select high, medium or low kinetic energy recovery intensity from the iDrive menu for all driving situations.
The maximum mileage in the WLTP test was up to 460 km, equivalent to the energy efficiency level of 520 km in the NEDC test.These innovations will also be available in i4 and iNEXT in the future.The power consumption of iX3 per 100 kilometers is 19.5-18.5kwh (WLTP), which is more than 30% higher than the efficiency of internal diesel powered X3xDrive20d. If the power comes from green energy, the efficiency is about 60% higher.The iX3 is also equipped with innovative charging units, and the combined charging Unit (CCU) used can be used for various types of charging stations with extremely high flexibility.

When AC terminals are used, CCU can achieve single-phase charging with 7.4kW power, or Wallbox three-phase charging with up to 11kW(0 to 100% charging within 7.5 hours).Due to significant progress in battery development, iX3 high voltage batteries have a higher number of batteries per module, but fewer components, making them more compact and thin.The overall battery is made of aluminum and divided into 10 modules, with a total weight of 518kg, consisting of 188 independently controllable prism cells. The weight/energy density is increased by 20% and the total power is 80kWh(the total operating power is 74kWh).
With a liquid cooling/heating system, the cooling system can perform two stages of control to maintain the best operating temperature;The high efficiency heat pump system, even when the outdoor temperature drops to minus 30 degrees Celsius, can control the excellent operating temperature of the battery and the temperature in the car, and consumes 40% to 80% less electricity than the traditional electric heating system (depending on the outdoor temperature).With a 150kW DC quick charge, the battery can be charged from zero to 80% power in 34 minutes, and it only takes 10 minutes to add 100 km of power (WLTP).
In addition to providing lighting, driving assistance system, sound system, seat heating and other on-board 12V power supply, CCU also specially provides 4kW transformer system to provide all passengers with convenient power supply.The iX3 will go on sale in late 2020 and begin deployment in China.The new iX3 will be BMW’s first electric vehicle to be exported from China, thanks to its joint venture plant in Shenyang, China, where eDrive components are also made.
