The system Electronic Q2 se basa en harnessing installing brakes that sent adequately by the switchboard ESP, creates a behavior very similar to that of a limited slip differential (eg Torsen mechanical device called Q2). In particular, the front brake system, in terms of acceleration curve, timely intervenes in the internal wheel, thus increasing the motor outside of the wheel (more loaded), and thus spreading the torque between the front-wheel drive so dynamic and constantly under driving conditions and the firm of the road. Electronic Q2, which combines the front suspension of quadrilateral exclusive, allows a particularly effective line of the vehicle and sports.
In fact, part of Alfa Romeo's reputation optimal traction among customers presumed front (it is no coincidence that is the solution chosen by the majority of automotive Properties). Suffice it to say that, beyond all the benefits of this type of architecture (weight, habitability, etc..) Under the conditions limits, the behavior of understeer a traction front allows the driver to respond to the efforts of the vehicle a more intuitive : Hence the feeling that the front traction is "sincere" that a rear traction.
By contrast, for versions 4 x 4, the system combines the Electronic Q2 rear axle subsequently increasing the known qualities of pleasure and ease of driving of Q4, giving even greater perception of sportsmanship: the behavior is an integral 4 x 4 with Torsen central and rear electronic limited slip differential.
Therefore, to exalt these benefits, Alfa Romeo has perfected the system Electronic Q2 representing all the strengths of the front traction and traction 4 × 4 significantly increasing grip on the road, motor, stability to drop and the brake, while cushioning the understeer in the acceleration and discomfort in the steering wheel.
