Good news for those who thought Audi's flagship RS cars just weren't fast enough; the firm has announced more powerful 'Performance' editions of the RS6 Avant and RS7 Sportback. Both models get a 45bhp power boost, up from 552bhp to 597bhp.
Thanks to tweaks to the 4.0-litre twin turbo V8's engine mapping, the two RS Plus editions also get an extra 50Nm of torque rounding out at an astonishing 750Nm. That means a 0-62mph time of 3.7 seconds, two-tenths better than the standard car and as fast as a Ferrari FF.

Top speed stays at the limited 155mph, unless you spec the Dynamic package which raises it to 174mph on the RS6 and 189mph on the RS7. Despite the performance boost fuel economy is unchanged, with the RS6 managing 29.4mpg and the RS7 29.7mpg. CO2 emissions are 223g/km and 221g/km respectively.
Subtle styling changes for the Performance adition include titanium exterior detailing, 'Quattro' grille badging, 21-inch alloys and a new blue paint finish option. UK prices are yet to be revealed, but expect a £4.000 increase over the standard RS6 and RS7. Given the new S8 Plus, we can expect similar 'Plus' badging for UK models.
