This Is How The New All-Wheel Drive System With Alfa Romeo's Q4 Technology

It was just yesterday when we commented that since its debut at the Paris Motor Show, Alfa Romeo will offer – for 55,500 euros in Italy – the Giulia Veloce, a model that comes with two interesting engines, a lot of equipment and best of all, a Traction system integral of which today we are going to speak…

In the Giulia Veloce debuts the new 2-liter gasoline engine (a 4 cylinder made entirely of aluminum) that develops a power of 280hp at 5250 rpm and a maximum torque of 400 Nm at 2250 rpm. In addition to the electrohydraulic actuation system of the MultiAir valves, the peculiarities of this engine include the “2 in 1” supercharging system and the direct injection with a high pressure system of 200 bar, which translate into a particularly fast response when driving The accelerator at any speed and in a remarkable efficiency in the consumption.

As an alternative, the Giulia Veloce can be equipped with the new 2.2 Diesel that develops a maximum power of 210 hp at 3500 rpm and a maximum torque of 470 Nm at 1750 rpm. In particular, the Giulia 2.2 turbodiesel is the first Diesel engine in the history of Alfa Romeo made entirely of aluminum. This four-cylinder in-line is characterized by the state-of-the-art MultiJet II injection system with Injection Rate Shaping (IRS) and 2000 bar operating pressures.

The variable-geometry turbocharger of electric drive represents the most advanced in mechanics and minimizes the response times, guaranteeing also advantages in terms of efficiency. The most sophisticated levels of comfort and driving experience are also guaranteed by the use of a counterbalancing balancing shaft.

Both mechanics are associated with the automatic transmission of 8 speeds.

The Q4 system architecture that equips the Giulia Veloce includes an active transfer case and a front differential designed to adapt to the specific technical requirements of Alfa Romeo, in order to control a high torque in very fast times with a specially compact design and Light weight ( weight gain only 60 kg ). The transfer case uses state-of-the-art active clutch technology that provides extremely dynamic driving while ensuring reduced fuel consumption. The responsiveness and torque distribution accuracy are guaranteed by the Next-Gen integrated actuator, depending on the mode selected by Alfa DNA.

This technology is able to predict the loss of wheel grip, based on the information gathered by the lateral and longitudinal acceleration sensors, steering wheel angle and vehicle skidding speed. In normal conditions, the Giulia Veloce with Q4 system behaves like a rear-wheel drive vehicle: 100% of the torque is sent to the rear axle. Approaching the wheels’ adhesion limit, the system transfers in real time up to 60% torque to the front axle, thanks to a specific transfer case.

A rear-wheel drive vehicle.
