Electronic Q2 Feature part 1

The fantastic Alfa Romeo update for 2008 on all Alfa Brera, Spider, 159 and 159 Sportwagon has great advantages:

Example one: Vehicle cornering While following a curve in low grip conditions (wet roads, snow, sleet, etc.) or when driving in a sporty manner, one often encounters loss of grip of the internal wheel. At the moment in which the internal wheel loses its hold of the road surface, a traditional differential transfers an amount of torque to the outer wheel equal to that of the inner wheel, which is insufficient for adequate traction. During this situation there can be two different solutions, depending on the equipment level of the car. In fact, on a model not equipped with ASR –VDC, the perceived result is internal wheel spin and loss of vehicle control (a high level of understeer) as well as a lack of acceleration when exiting the curve. If, on the other hand, the vehicle is equipped with ASR - VDC, the systems will intervene by reducing engine torque output, by means of controlling the throttle valve and acting on the brake system, which makes throttle modulation impossible leading to the undesirable impression of power loss.. In both cases, the result is that one perceives being “sluggish” while exiting the curve.

What happens when the “E-Q2” system is present At the moment in which the inner wheel loses grip, the torque is being partially transferred to the external wheel by means of light braking pulses to the inner wheel, resulting in reduced understeer, increased stability and higher cornering speed. All of which increases vehicle control and driving pleasure.
