Making of BMW iX,All Electric BMW iX Development, Testing in wind tunel, arctic cold & Heat,
The fifth-generation BMW eDrive technology fitted in the BMW iX is centred around a drive unit which brings together the electric motor, power electronics and transmission within a single housing. This highly integrated electric drive system topology has a beneficial effect on both power density and efficiency, at the same time as making highly economical use of the installation space in the area between the front and rear axle.

Both motors in the BMW iX work according to the principle of an electrically excited synchronous motor, where the excitation of the rotor is induced by the feed-in of electrical energy rather than fixed permanent magnets. This enables them to put their maximum torque on tap immediately on pulling away and maintain it over an extremely broad rev band. Combined torque peaks at 630 Nm (464 lb-ft) in the BMW iX xDrive40 and an even higher 765 Nm (564 lb-ft) in the BMW iX xDrive50.

The BMW iX is ready for series production and is due to arrive on the world’s roads from November 2021. The BMW Group’s new technology flagship combines locally emission-free driving pleasure, sporting agility and a compelling operating range with a character profile dedicated squarely to sustainability. With its trailblazing design and an interior devoted to luxurious spaciousness, the BMW iX embodies a fresh new take on the Sports Activity Vehicle (SAV) concept. Conceived from the outset for purely electric mobility, this model is based on a new toolkit for the future, whose vast potential for innovations in the areas of automated driving, operation, connectivity and digital services translates into a premium mobility experience unparalleled in this segment.

The BMW iX will be launched with a choice of two model variants. Both are equipped with an electric all-wheel-drive system, with combined output of 385 kW/523 hp in the BMW iX xDrive50 (electric power consumption combined in the WLTP cycle: 23.0 – 19.8 kWh/100 km [62 miles]; CO2 emissions: 0 g/km) and 240 kW/326 hp in the BMW iX xDrive40 (electric power consumption combined in the WLTP cycle: 22.5 – 19.4 kWh/100 km [62 miles]; CO2 emissions: 0 g/km). The drive technology’s efficiency paired to the very latest battery cell technology results in WLTP-calculated ranges of up to 630 kilometres (391 miles) in the BMW iX xDrive50 and up to 425 kilometres (264 miles) in the BMW iX xDrive40. Also set to join the model line-up at a later date is the BMW iX M60 (electric power consumption combined in the WLTP cycle: 21.6 kWh/100 km [62 miles]; CO2 emissions: 0 g/km) with a maximum output in excess of 440 kW/600 hp that promises an exceptionally sporty all-electric driving experience. (The figures relating to motor output and energy consumption for the BMW iX M60 are predicted values based on the car’s current stage of development.)


The standard chassis technology for the BMW iX comprises a double-wishbone front axle, five-link rear axle, lift-related dampers and an electric steering system with Servotronic function and a variable ratio. Two-axle air suspension with electronically controlled dampers, Integral Active Steering and Sport brakes can all be found on the options list. As an alternative to the standard 20-inch light-alloy wheels, there is a choice of 21-inch and 22-inch Air Performance Wheels. These can be fitted with noise-reduced tyres, which have a layer of foam on their inner surface to improve acoustic comfort.

Electric all-wheel drive and near-actuator wheel slip limitation.
The electric all-wheel-drive system in the BMW iX transmits exactly the right amount of drive torque to the front and rear wheels in all driving situations. Its intelligent control enables fully variable power transmission ranging from highly efficient pure rear-wheel drive through to an all-wheel-drive set-up that maximises traction.

The near-actuator wheel slip limitation technology fitted in tandem with all-wheel drive for the first time brings about a further improvement in traction and handling stability. Integrated into the motor management, this system produces very precise and lightning fast corrective inputs and thereby enables the car to make effortless progress at all times, even in adverse weather and road conditions. The BMW iX xDrive50 posts acceleration of 0 to 100 km/h (62 mph) in 4.6 seconds, while the BMW iX xDrive40 hits the same mark from rest in 6.1 seconds.
