BMW xDrive Technology Featured in the New BMW 2 Series Active Tourer
BMW continues to progress and develop in the field of drive technology. With its intelligent four-wheel drive system BMW xDrive, first used in the BMW X3 and the X5 in 2004, the manufacturer adds a high degree of functionality, improved cornering dynamics and tries to achieve minimum fuel consumption and low emission levels.
Now, the most recent example of model-specific alignment of the four-wheel drive system is served by the BMW 2 Series Active Tourer models. The most cardinal difference when it comes to previous variants and the last ones is that, for the first time, BMW xDrive is used on a front-wheel drive concept with transversely installed engines.
With the BMW 225i xDrive Active Tourer (combined fuel consumption of 6,5–6,4 l/100 km and CO2 emissions of 152-148 g/km) and the BMW 220d xDrive Active Tourer (combined fuel consumption of 4,8-4,6 l/100km with CO2 emissions of 127-122 g/km), the intelligent four-wheel drive system is now available for top-notch power units. Both BMW vehicles are equipped with BMW xDrive as standard in combination with the 8-speed Steptronic transmission.
What the xDrive system does is utilizing an energy-efficient operating strategy which enables the BMW 2 Series Active Tourer to be driven only via the front wheels. And since, in this case, BMW is really about compactness, convenience and practicality, in order to make use of additional saving potentials, the manufacturer has given the multiple-disk clutch a spring-loaded Efficient valve. It decreases the oil level in the clutch and reduces friction losses (oil splash losses).
Furthermore, thanks to the Dynamic Stability Control feature (DSC), which analysis, collects and provides an information about the running condition, any possible wheel slip, for instance, is detected at an early stage. Additionally, the xDrive manages and directs excess force to the front wheels in case the rear of the vehicle turns outwards. This ensures an ultimate four-wheel performance which is possible even before the occurance of any swerves. In consequence, xDrive featured in the BMW 220d Active Tourer and BMW 225i Active Tourer provides with better traction, more safety in different road conditions and enhances the vehicle stability, cornering dynamics and ride comfort.
