Power increases from 195kW to 280kW between 6100 and 7000rpm, while peak torque of 440Nm (up from 400Nm) is available from 2500rpm to no less than 6000rpm. Redline arrives at 7000rpm. In conjunction with British Cosworth Technology, which has been part of the Audi Group since 1999, the cylinder-head has been redesigned and is produced using a specially developed casting technique. The admission and exhaust ports have been modified in line with the engine's higher performance, and the cross-section of the air ducts at both the intake and thrust side enlarged. The turbochargers have been enlarged and boost pressure has been increased compared with the S4. The use of larger charge-air coolers with less pressure loss has also improved efficiency. Quick? 0-100km/h is a claimed 4.9 seconds 0-200km/h requires 17.0 seconds and top speed is limited to 250km/h. EU fuel economy figures point to a thirsty 17.0 L/100km on the city cycle and 9.0 L/100km on the highway. Did you know?The RS4's engine's efficiency was also boosted by a new dual-branch exhaust system developed by quattro GmbH, comprising backpressure-optimised middle and rear silencers, larger-section pipes, and primary and main catalytic converters with a metal baseAll 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 |
