Audi will launch high-performance S6 saloon and Avant, S7 Sportback and S8 luxury car at the Frankfurt motor show next month.

The cars all feature a new V8 4.0-litre TSI engine, with the S6 and S7 getting a 414bhp version, while the flagship S8 comes software upgrades that boost power output to 513bhp.

Despite an increase in performance over the existing S models, Audi says fuel consumption has improved by as much as 25%.

The performance models all have what Audi calls 'cylinder on demand' technology which helps fuel economy. Four of the engine's eight cylinders can be deactivated – therefore use less fuel under certain conditions. Audi says this is most pronounced at 'moderate highway speeds'.

To counter any refinement issues from deactivating four cylinders, Audi says it has a package of acoustic measures including its Active Noise Cancellation (ANC) system.

Four microphones record the noise in the cabin which is analysed by a computer. If the computer detects unwanted noise, it broadcasts an 'antiphase' sound through the stereo speakers which in theory cancels out the intrusive sound.

There's no word yet on prices or on-sale dates for any of the models, but order books should open by the end of the year.
