Alfa Romeo 147 Q2

The Alfa Romeo 147 Q2 is equipped with front differential (Q2), which provides some advantages of a typical wheel drive, but with the greater weight and a far lower cost.


Alfa Romeo 147 Q2

The Q2 system of the Alfa Romeo 147 Q2 is based on the presence of a limited slip differential, a mechanical Torsen. In particular, this differential has the task of sharing the couple between the front wheel drive so dynamic and continuously under the conditions of driving and road.

Moreover, tied exclusively to a quadrilateral front suspension, the system allows a particularly efficient tuning of the vehicle. The Alfa Romeo engineers, in fact, started high reputation that the front has traction among customers (not by chance is the solution chosen by the majority of Car).

Beyond the benefits of this type of architecture (weight, space, etc.) A significant increase safety for drivers. On the other hand is also said that the front wheel drive - because the wheels are driven - may jeopardize the full pleasure and control in certain driving conditions giving rise to problems in traction curve, a behavior or limit reactions on the steering.

To overcome these drawbacks the Alfa Romeo 147 Q2 has developed the Q2 system that makes all its strengths traction earlier by significantly increasing road holding, traction and stability issue, and at the same time, weakening in the acceleration, the intervention of electronic controls and vibration on the steering wheel.

Going through a curve in conditions of poor adhesion (wet roads, snow, mud, etc.). Or driving in a sport often you are in a position to lose grip of the wheel inside, due to the fact that the differential divides torque to the wheel more "download" that external funding away from that, being burdened by the weight of extra roll of the Alfa Romeo 147 Q2, could use a higher total friction.

In this situation you can have two different answers depending on equipment of the Alfa Romeo 147 Q2. Indeed, on a model without ASR - VDC, the perceived result is a skating inside of the wheel, a loss of vehicle control and the lack of acceleration at the curve.

If the Alfa Romeo 147 Q2 is equipped with ASR - VDC, the intervention of driver assistance systems remove power to the engine, acting on the throttle, making it impossible modulation throttle and giving an unpleasant feeling of loss of power and interaction with Alfa Romeo 147 Q2. In both cases the result is that at a curve one has the feeling of being "firm".

When the inner wheel starts to lose grip, torque is partially transferred to the outer wheel ensuring a greater stability, higher speeds, the curve, a system of vehicle control and less frequent invasive. For the benefit of driving pleasure and full control of the vehicle.

In March on soils with low grip conditions, often going to have the driving wheels in a different drive. For example, along a road after a snowfall or intense rain, a wheel at the edge of the road, in direct contact with residual snow, while the other is in an area already clean or dry.

In these particular circumstances, a departure or a strong accelerated port to have a slip of the wheel with plight of friction, with strong reactions on the steering wheel, an inadequate basis and the need to make continuous adjustments with the steering wheel to maintain the trajectory.

The negative effects are countered by the gradual transfer of torque to the wheel that can exploit the greater coefficient of friction, making it easier, for example, a starting uphill on a mountain road and more safe and comfortable walking on stretches of road with the changing conditions of the road.

In short, the sophisticated Q2 system is further Alfa Romeo demonstration of excellence in finding technical solutions-oriented security and driving pleasure.

Within the new version offers an environment more sports, underlined by instruments with red scale background and white back lighting, black leather seats with red stitching and logo Alfa Romeo 147 Q2.

To complete the allocation of the Alfa Romeo 147 Q2 there are cruise control, radio commands to the steering wheel, car CD player with MP3, Hi-Fi Bose ® with sub-woofer.
