If you want a little more out of Audi's new RS 6 Avant than the 412kW and 700Nm its 4.0 litre V8 offers, reports out of the UK suggest you might soon get it.
Speaking with UK magazine Car, Quattro GmbH boss Stephan Reil has confirmed that Audi’s in-house tuners are developing a new 450kW variant that will enter above the 'regular' twin-turbo 4.0 litre V8 RS 6.
These are not the first ‘Plus’ models in Audi’s history though, with the suffix previously applied to limited-build versions of the C4-generation S6 from 1996-97 and C5 RS 6 model in 2004.
Reil indicated that a new RS 6 Avant Plus will not appear until at least 2014, but will feature an 8-10 percent power gain, suggesting a figure between 445-453kW.
This would likely drop the RS 6’s 0-100km/h time from 3.9 seconds to somewhere nearer the 3.6 second figure claimed by the freshly revealed all-wheel drive Mercedes-Benz E 63 AMG 4Matic S-Model - and even further ahead of the 4.3 second BMW M5.
The report also suggests weight savings are possible for the RS 6 Avant Plus, likely through a greater use of aluminium and composite materials for the benefit of handling dynamics.
“A Plus model could have more power, or less weight, and a Plus model should always handle differently to the standard car,” Reil told Car.
Asked whether ‘Plus’ versions are likely for the existing naturally aspirated RS 4 and RS 5 models, Reil said the 4.2 litre V8's 331kW/430Nm outputs are near its maximum potential - nullifying the motivation for an uprated version.
“It could perhaps produce 343kW but you would not feel it,” Reil said.
With a Plus model still to be confirmed, and the regular RS 6 not due locally until the end of the year, it won’t be happening overnight.
