It’s time to head for the ski slopes again – and in the ice and snow of winter all-wheel drive systems come into their own. However, this is only part of the story, because an intelligent all-wheel drive system can also ensure increased safety and improved driving dynamics all year round without having to make compromises in terms of everyday suitability. The best examples of this are the intelligent all-wheel drive systems fitted to the Opel Insignia Country Tourer, Opel Insignia OPC and Opel Mokka SUV. They represent the technical pinnacle of over 100 years of all-wheel drive development within the automotive industry. Opel’s all-wheel drive systems are now so sophisticated, they can sense and adapt to changing conditions even before a critical driving situation occurs.

The development of the complex, networked drive systems in today’s Opel models has matched the pace of change seen in the digital information age. For example, at its market launch 22 years ago, the Opel Frontera, a trendsetter in the SUV segment and one of the best-selling off-road vehicles in Europe, still relied on the classic, mechanical on-demand all-wheel drive system. Now its grandchild, the Opel Mokka SUV, controls power distribution on demand with electronic bits and bytes. This, of course, also applies to Opel Insignia 4x4 models led by the Country Tourer. Electronics have become established as a means of ensuring the best-possible distribution of power. In this way, intelligent Opel all-wheel drive technology seamlessly joins safety systems such as ABS and ESP.

The advantages of having an on-demand control of power distribution are immense in comparison with purely mechanical systems still sometimes used today. The inherent drawbacks of such simple all-wheel drive systems – for example, twisting in the drivetrain, substantially higher fuel consumption and a reduction in driving comfort due to stronger vibrations – are almost completely eliminated by the intelligent all-wheel drive systems in today’s 4x4 Opel models. Opel systems score with a precise, on-demand power distribution which reacts in milliseconds to changing driving situations. This makes them clearly superior to other on-demand all-wheel drive systems which rely on the purely mechanical control of power distribution when wheel slip occurs. This usually happens after a noticeable time delay, which has a corresponding negative impact on driving dynamics and comfort levels.

The differences between the all-wheel drive systems in the Opel Mokka, Opel Insignia Country Tourer and Opel Insignia OPC models are the result of different objectives in line with the specific requirements of each vehicle concept.

The all-wheel drive system is activated when the Opel Mokka is stationary to prevent wheel slip at take-off. It also engages unobtrusively in a split second as soon as the driver depresses the clutch pedal. Once up and running, all power is transferred to the front wheels and the all-wheel drive system is only engaged when driving situations require it. As with most SUVs, the Mokka’s all-wheel drive system is supported by Hill Start Assist (HSA) and Hill Descent Control (HDC). Electronic traction control also replaces the function of the axle-differential lock with automatic braking intervention.

When developing the 4x4 variant of the Insignia, Opel engineers focused on optimizing driving dynamics. While the all-wheel drive architecture and its integration with CAN bus data is similar to that of the Opel Mokka, an electronic Limited-Slip Differential (eLSD) has been introduced alongside the multi-disk clutch on the rear axle. This enables power to be distributed transversely, between the rear wheels, as well as longitudinally between the axles. Optimal adaptive driving dynamics are ensured by sporty control logics and the system’s ability to transfer all drive torque to the rear axle. Together with the intelligent limited-slip differential, which also seamlessly distributes power according to the prevailing driving situation, the Opel Insignia 4x4 offers a unique experience which gives the driver best-possible vehicle control. The ESP’s control strategy has also been optimally adapted to suit the all-wheel drive system. As a result, drivers can fully exploit the enhanced driving dynamics of the 4x4 Opel Insignia, especially when 325 hp is available from the powerful OPC version. With Opel’s fast-acting all-wheel drive system, driving safety and driving fun both reach new levels.
