Audi has added the performance-oriented S4 sedan to the local A4 range, adding more power but a lower price compared to the previous generation.
Styling enhancements are subtle – and inside the cabin the luxury feel is obtained through leather, matt-brushed aluminium and chrome. Standard equipment includes in-car wifi connectivity via a dedicated sim card, 8.3-inch centre display including satellite navigation, Apple CarPlay and Android Auto, Audi Virtual Cockpit and three-zone air-conditioning.
Power comes from a 3.0 TFSI turbocharged petrol V6 making 260kW between 5400rpm and 6400rpm (up 15kW compared to its predecessor), while peak torque of 500Nm (up 60Nm) is available from 1370rpm to 4500rpm. Power is transmitted via quattro all wheel drive through an eight-speed Tiptronic automatic in place of the previous version’s S-tronic dual-clutch seven speed automatic, with torque converter and paddle shifters for the manual override.
The 90-degree engine sports the twin-scroll turbocharger between its cylinder banks, and integrated exhaust manifolds speed up the spooling process, thereby reducing lag.
The Quattro mechanical AWD system sends 60 percent of torque to the rear axle, but can apportion up to 85 percent if the car’s sensors detect a loss of traction. It can also direct 70 percent to the front axle.
The S4 Avant adds practical standard features including a powered tailgate with kick to open and close functionality, a retractable cargo cover, and 505 litres of boot space to the top of the rear seats or 1510 litres with the rear seats folded. All S4 variants feature adaptive suspension dampers as standard, a mechanical centre diff, with a static 40:60 front rear split that can vary torque up to 85 percent to either axle. An optional rear sport differential can apportion even more torque to the rear wheel with the most grip.
Audi claims 0-100km/h times of 4.7 seconds for the sedan and 4.9 seconds for the Avant – a reduction of 0.3 seconds compared to the old S4. Fuel consumption is rated at 7.7 l/100km for the sedan and 7.8 l/100km for the Avant. Safety systems include eight airbags, stability control, active lane assist, adaptive cruise control with stop and go and traffic jam assist, 360-degree surround camera system, Audi pre-sense front, turn assist, collision avoidance assist and high beam assist.
