Although styling differences are only subtle, the S4 range sits 23mm lower than a regular A4 on larger 19-inch alloy wheels. Unique front and rear bumpers, quad-tipped exhaust, and aluminium-look mirror housing round-out the S4’s changes.
With sedan pricing starting from $99,900 (plus on-road costs) the S4 range starts more than $6200 below the previous generation and splits the difference between its closest rivals, the BMW 340i at $89,855 and Mercedes-AMG C 43 from $104,400.
Inside, the cabin is dressed in leather, matt brushed aluminium, and chrome-look highlight lines, with standard equipment extending to in-car wi-fi 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..
The wide-angle 90-degree V6, to be shared with the coming S5 and SQ 5, features twin turbochargers mounted within the cylinder banks for lighter weight, more compact under-bonnet packaging and better pedestrian impact protection.
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.
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. For $2900 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.
