Audi S6 and S6 Avant uncovered
* New 414bhp, 4.0-litre TFSI engine * Saloon: 0-62mph in 4.8seconds, 29.1mpg * Order books open later this year...
Audi's S6 and S6 Avant will get their public debuts at the Frankfurt motor show next month, before going on sale by the end of the year.
The cars have a new eight-cylinder twin-turbo 414bhp 4.0-litre TFSI, which powers the saloon from 0-62mph in 4.8 seconds the Avant is just 0.1 secs slower while both have a limited top speed of 155mph.
Compared with the 5.2-litre V10 in the previous S6, this version is 25% more fuel efficient, average 29.1mpg in the saloon and 28.8mpg in the Avant. This is achieved, in part, thanks to Audi's cylinder on demand system.
Both have a seven-speed S tronic gearbox, Audi's quattro four-wheel-drive system and adaptive air suspension.
As well as being slightly longer than the standard A6 and A6 Avant, the S versions come with sporty styling inside and out, including rear spoilers, four chrome-tipped exhaust pipes, chrome detailing on the front bumper and grille.
