The S4 models follow the all-new A4 sedan and wagon, which broke cover in June and will join the S4 at the Audi stand in Frankfurt making their first public appearance.
For the powered-up S4 models, the same 3.0 litre turbocharged petrol V6 form the previous model will send drive to all four wheels via Audi’s quattro system.
While the engine is the same, power has been lifted from 245kW/440Nm to 260kW and 500Nm while the dual-clutch automatic transmission gains an extra ratio to become an eight-speed unit.
The 0-100km/h sprint has been shortened to match the new power output, with the new time of 4.7 seconds bettering the old model by 0.4 seconds. Top speed is limited to 250km/h.
As with the regular A4, the new S4 has been on a diet which sees fuel consumption improve to 7.4 l/100km - down from 7.8 l/100km - and the automatic transmission features a ‘freewheeling’ mode to save fuel when drive isn’t required from the engine.
Weight has dropped from 1780kg in the S4 sedan and 1825kg in the Avant to 1630kg and 1675kg respectively.
The quattro system can regulate power from front to rear, with a 40/60 front/rear split during normal driving. Under load, up to 70 percent can be sent to the front and up to 85 percent to the rear.
Audi says a new suspension set-up for the 2016 S4 sees cornering speeds improve along with straight-line stability, while a ‘variable speed-dependent dynamic steering’ system is optional.
The German carmaker describes the S4’s new look as “sporty understatement”. An 18-inch alloy wheel design is standard fitment, while a 19-inch package is optional.
Inside, passengers will experience a quieter ride compared to the outgoing model, with Audi claiming the new S4 models set new standards for the class.
Cargo space ranges from 505 to 1510 litres in the Avant depending on the position of the rear seats, with 480 litres on offer in the sedan boot.
Elsewhere, there’s sports seats wearing Nappa leather and Alcantara available in rotor grey, magma red or ebony, along with a fully-digital instrument cluster, an eight-inch touchscreen and vastly improved phone connectivity.
Safety features include lane assist, park assist, cross traffic alert, road sign recognition, and adaptive cruise control with traffic jam assist which can operate semi-autonomously at speeds of up to 65km/h.
“At Audi, we have more than 20 years of expertise in developing our sporty S models,” Audi’s Professor Dr Ulrich Hackenberg said.
“From day one, our formula for success has been a combination of outstanding quattro performance, restrained design, and state of the art drivetrain, suspension, and infotainment technology. The new Audi S4 and S4 Avant impressively continue this sporty tradition.”
The new Audi S4 and S4 Avant will go on sale in various markets from next year. The first models are expected to arrive in Australia around the end of next year, with pricing and specifications yet to be confirmed.
