HE ALL-NEW AUDI S8, the fifth generation of the company’s flagship luxury sedan, has arrived in Australia and it looks to be a brilliant piece of work. At the heart of the S8 is a brutal 4-litre TFSI V8 engine sporting two twin-scroll turbochargers and generating 420kW and 800Nm of torque from 2,000 - 6,000 rpm. The potent engine propels the S8 to some truly impressive performance numbers. 0-100km/h is reached in just 3.8 seconds, and top speed is limited to 250 km/h. The engine is made with a cast aluminium crankcase that weighs just 39.1kg, has an advanced variable oil pump arrangement, variable camshafts and a sophisticated fuel injection system. Intelligent efficiency systems further enhance the engine's performance. Its 48-volt mild-hybrid electrical system can recover up to 8 kW of power while coasting or under light throttle. The start/stop system also draws on the 48v electrical system, saving up to 0.8 litres of fuel, per 100km. Additionally, cylinder on demand (CoD) technology Audi S8

Under normal driving conditions, torque is distributed asymmetrically: 40:60, front to rear respectively. However, up to 85 per cent of engine torque can be directed to the rear wheels for especially sporty handling. The quattro sport differential can provide further VIDEO: 2021 AUDI S8
