The BMW of the near-future will have your gearchanges ready before you think you'll need them

Engineers at BMW are busy developing new 'Predictive DriveTrain Technology' that will be capable of improving your driving without you even noticing.

BMW 5 Series review

The system uses the current sensor arrays and radar hardware found in Adaptive Cruise Control systems to carefully monitor the traffic around you, and should the situation dictate, will prime the car's automatic transmission with a lower gear to improve response. 

Normally, as a driver approaches slower cars in the lane ahead and decides to overtake, a quick prod of the throttle pedal causes the gearbox to change down, creating a pause before it's safe to perform the overtaking manoeuvre.

• Driverless cars: all you need to know

Using BMW's new system, the nose-mounted radar detects the slower car ahead, the system predicts the potential overtake and as soon as the indicator is touched to signal out the transmission seamlessly engages a lower gear to enable a smooth move. This also has benefits in terms of reductions in fuel consumption by using 'overrun' shifts up rather than power shifts down.  

Another benefit of this new technology is discovered when merging with other traffic. Should the side and rear sensors detect a vehicle in the car's blind spot it will automatically boost acceleration by downshifting and enabling the car to nip in front and avoid any potential incident.

BMW engineers say that intensive testing of this system will continue for up to another year before being rolled out to customers, and although the system uses no additional hardware it is not yet known whether it could be added to existing vehicles as part of a software upgrade.
