In addition to the levels of roadholding afforded by the quattro four-wheel drive system, ESP further improves car control by monitoring and manipulating a variety of systems. These include the functions of the anti-lock braking system (which itself is assisted by electronic brake-force distribution), electronic differential lock, anti-slip regulation, engine drag torque control and the higher-level yawing moment controller. That's a lot of electronic gizmos to digest, but basically ESP can detect, and then counteract, any oversteering or understeering tendency. Did you know?One of the main players in getting four-wheel drive from the farm and onto the bitumen was Dr Ferdinand Piech, who in 1977 was chief technician at Audi. Today, Piech is chairman of Volkswagen AG's board of managementAll car reviewsAlfa Romeo Abarth Alpine Alpina Audi Aston Martin BMW Bentley Chevrolet Chery Citroen Chrysler Dodge Cupra Ferrari DS Ford Fiat FPV Foton GWM Great Wall Holden Haval HSV Honda Hyundai Hummer Isuzu Infiniti Jeep Jaguar Lamborghini Kia LDV Land Rover Lotus Lexus Maserati Mahindra McLaren Mazda Mercedes-Benz Mercedes-AMG Mini MG Nissan Mitsubishi Peugeot Opel Proton Porsche Renault Ram Rover Rolls-Royce Skoda Saab SsangYong Smart Suzuki Subaru Toyota Tesla Volvo Volkswagen |
