BMW celebrates the 25th anniversary of the BMW 325iX – the first all-wheel-drive car – this year. It’s a rare occurrence not to come across the cars that had been derived from it -- from gas guzzling SUVs such as the X5 to the 3 series 328i xDrive.
The BMW 325iX was the first of its kind when it was introduced in 1985. It featured the sharp steering prowess that all BMW models are famous for along with improved traction in challenging conditions. Back then, the model was only offered with one engine: a 2.5-liter six-cylinder petrol engine that delivers 171 hp (126 kW).
Power was divided between the front and rear axles at a constant 37 to 63 split, favoring the rear. In the 1990’s, more complicated electric controls started to be used, controlling power distribution.
BMW’s 5 Series was the first to apply the system that features multi-plate clutches that changes the amount of power sent to each corner of the car. Its engineers were truly tested with the arrival of the X5, the first dedicated SUV built by the company.
Each action of the car is controlled by sophisticated on-board computers through standard systems such as Dynamic Stability Control (DSC), Automatic Differential Brake (ADB-X) and Hill Descent Control (HDC).
In the last 25 years, BMW was able to steadily make a name for itself with cars that provide good handling partnered with traction in all driving conditions. Because of this, one in four BMW cars sold around the world now features the xDrive. With the time that has passed, enthusiasts are eagerly awaiting a special edition 325iX rally worthy car.
