Ingolstadt is bringing the Audi RS 6 Avant back into the game, this time together with the RS 7 Sportback. Both have now been given a “performance” label, replacing the “plus” suffix used on older models.

At the heart of the vehicles lies the same twin-turbo 4.0 litre TFSI V8 engine, which has now been tuned to produce 605 hp and 750 Nm. That’s 45 hp and 50 Nm more than the “standard” variants. Here, an overboost function is present – this lets the driver obtain the full 750 Nm of torque.

The engine management system has been tweaked to give the turbocharger added boost pressure, while both continue to be paired to an eight-speed Tiptronic gearbox with Sport and Manual modes. The 0-100 km/h sprint is now done in 3.7 seconds, which is 0.2 seconds faster than before, while accelerating from 0-200 km/h is done in just 12.1 seconds, 1.4 seconds faster.

A dynamic package that lifts the top speed from 250 km/h to 280 km/h can also be specified by customers. Although the performance models feature more power, Audi claims that the fuel consumption numbers are unchanged. The Audi RS 6 Avant performance averages 9.6 litres per 100 km, and the RS 7 Sportback performance achieves 9.5 litres per 100 km.

Of course, quattro all-wheel drive comes as standard on both model, while an optional sport differential with active torque distribution on the rear axle is an option. Suspension-wise, the performance models come with a, RS-tuned adaptive air suspension that is lower by 20 mm. One can also choose the stiffer RS sport suspension plus with dynamic ride control instead.

Furthermore, other options to enhance the drive include dynamic steering with a continuously variable steering ratio, which can be integrated into the Audi drive select system. The system can now be switched between comfort, auto, dynamic and individual from a button on the RS multifunction steering wheel, similar to the Audi R8.

Inside, both models come with RS sport seats, while a new Alcantara and leather combination upholstery can be requested. The overboost function is displayed on the driver information system, changing from white to red when it’s activated. Additionally, other optional interior items include night vision assistance, adaptive cruise control with Stop&Go function and Audi connect.

Outside, the RS 6 Avant performance stays pretty much the same, but it now features updated LED headlamps and rear tail lights, matte black coated roof rails and rims in a 21-inch aluminium five-V-spoke star design, with a matte titanium and gloss finish. The RS 7 Sportback performance gets a different five-double arm design, in the same finish.

A new metallic colours is also available – Ascari Blue. The RS 6 Avant performance goes for 117,000 euros (RM550,225), while the RS 7 Sportback performance is priced at 121,700 euros (RM572,366). Both RS performance vehicles will go on sale in Germany in November.
