Alfa Romeo presents the self-locking front differential ('Q2'), which improves all the strong points of a front-wheel drive system in terms of active safety, increasing driving enjoyment and control. The innovative system provides some of the advantages typical of four-wheel drive, but at a significantly lower cost and weight. The system is now available exclusively with the 150 bhp JTDM engine on the Alfa Romeo 147 and Alfa Romeo GT, but will subsequently be extended to other models in the Alfa Romeo range. It is a step forward that reflects the current state of the art of turbodiesel technology which, since 1997, the year that the Alfa Romeo 156 JTD was launched (the first car to adopt Common Rail technology), has seen a considerable increase in torque delivery to the wheels even on compact cars. Alfa Romeo has developed the sophisticated 'Q2' system to guarantee maximum control and traction in all driving conditions.
