BMW’s new traction control system debuts with i3s and spreads across range
BMW’s updated traction control, introduced with the i3s, now reacts 50 times faster and will be fitted to all BMW and Mini models, including petrol and diesel cars.
BMW has launched a new traction control system claimed to react 50 times faster than its predecessor, debuting the technology with the i3s electric hatch before rolling it out to all BMW and Mini models, including those with petrol and diesel engines.
The new system, which BMW engineers developed to improve both traction and driving stability, was first seen on the i3s at its Frankfurt Motor Show debut in September 2017. The i3s, a sportier version of BMW’s compact electric car, features a more powerful 184hp (135kW) electric motor and revised suspension. The traction control upgrade was part of a broader mid-life refresh for the model.
How the new system works
BMW says the main advance is moving the control process directly into the powertrain, eliminating the longer signal paths of previous systems. This change means the system can respond to changing grip levels much more rapidly, particularly in adverse weather, during energy regeneration, or when accelerating out of tight corners. The result is more consistent and predictable handling, especially on slippery surfaces.
Not just for electric cars
Although the system was introduced with the electric i3s, BMW will fit it to all conventionally powered models as well. This includes front-, rear- and all-wheel drive configurations across both BMW and Mini brands. The company says drivers should notice greater assurance when pulling away in poor conditions and more stability under hard acceleration or regeneration braking.
The move comes as part of a wider effort by BMW to improve the driving experience through software and electronic controls, not just hardware upgrades. The company has not announced any changes to the hardware itself, focusing instead on the software’s role in managing power delivery and stability.
Context: i3s and the updated BMW line-up
The i3s sits at the sportier end of BMW’s electric range, with more power and firmer suspension than the standard i3. The traction control upgrade was one of several changes introduced in the model’s 2017 facelift. BMW has since confirmed that the faster-responding system will become a standard feature across its entire line-up, including future petrol and diesel models.
