2016 Audi S4 Spyshots-12

The new B9 Audi A4 was revealed in June, and we now have spyshots of a hotter S4 variant undergoing summer testing in the Alps, with no camouflage on the mule. A Frankfurt motor show debut later this month, perhaps?

The black coloured test mule seen here wears a more aggressive lower bumper than the A4 S line, which is already sportier in appearance than the standard A4. Compared to the S line, the S4’s bumper has larger air intakes, and there appears to be a vent at the outer edges of the intakes. Zoom into the lower edge of the single-frame grille and you’ll see that the lines turn outward. Yup, stuff that you have to squint to see.

At the back, a diffuser-like element and twin-pipes on each side of the bumper (double that of the standard car) mark it out as a higher-performance variant.

In the B9 A4’s petrol engine range, there’s a 1.4 TFSI with 150 PS/250 Nm and a pair of 2.0 TFSI units, one with 190 hp and 320 Nm and another with 252 hp and 370 Nm. The more powerful of the duo does 0-100 km/h in 5.8 seconds in the sedan and 6.0 seconds flat in the A4 Avant, with quattro AWD and the S tronic dual-clutch gearbox.

That’s the bar the S4 will have to beat with a comfortable margin. With the outgoing B8 S4 pushing out 333 PS, a figure of around 350 PS from a V6 turbo engine would a realistic expectation. Stay tuned.
