Continuing in the Ingolstadt idiom, the new RS 6 Avant looks pretty much like any other current Audi – only with the menace cranked up to hint at its performance capability…
You see, the new Audi RS 6 Avant will need just 3.9 seconds to dispel any doubt that its ultra-efficient new downsized V8 TFSI engine has compromised on muscle for the sake of miles-per-gallon. The latest super Avant will firmly cement its RS credentials by outrunning its ‘Aud-ini’ V10-powered predecessor with an exceptional sub-four-second 0-62mph sprint time. At the same time its smaller displacement and cylinder-on-demand technology will make 28.8mpg economy potential a reality.
Available to order early in 2013 priced at approximately £77,000 OTR, and due in the UK next summer, the new RS 6 Avant will derive its phenomenal pace from a twin-turbo 4-litre V8 TFSI engine which replaces its predecessor’s 5-litre twin-turbo V10 TFSI. Peak output of 552bhp in the new engine is reached between 5700-6700rpm, with a constant 516lb.ft of torque available between 1750 and 5500rpm.
The two large twin-scroll turbochargers enable the RS 6 Avant to gather momentum with remarkable intensity. They are mounted together with the intercooler in the inside V of the cylinder banks. The exhaust side of the cylinder heads is also on the inside, while the intake side is on the outside. This concept allows for a compact design and short gas paths with minimal flow losses.
The RS engine management and unthrottled intake system also contribute to the eight-cylinder engine’s response, which is delivered to the tune of a classic V8 soundtrack. Switchable flaps in the exhaust system will make the sound even fuller at the touch of a button, and a sports exhaust system will be available as an option to provide even greater amplification if required.
The big question though, will be – can the RS 6 deliver decent driver entertainment? We’ll have to wait and see, but if you don’t have the patience then Audi will be opening the order books early in the New Year with deliveries expected in Summer 2013.
