Will Audi's high-performance wagon drop the V8 engine?

The high-performance Audi RS4 Avant has been spied wearing a production body for the first time.

Dressed in swirly camouflage, the wagon follows in the footsteps of the S4 Avant but adopts a new front fascia with a revised grille and larger air intakes.  the model also has a tailgate-mounted spoiler, two large exhaust tips, and lightweight alloy wheels that are backed up by a high-performance braking system.

The interior is largely expected to carryover but drivers will likely find a number of unique touches including RS 4-branded sport seats.

Engine options remain unconfirmed but speculation suggests the model will be equipped with a 3.0-liter V6 engine that has two electric turbochargers.  The model's output remains a source of huge debate as various sources are claiming it will have between 420-450 horsepower while other are expecting between 480-500 hp.  Regardless of the final number, the engine will likely be connected to an eight-speed automatic transmission and a performance-oriented quattro all-wheel drive system.

Mercedes seems to turn out AMG variants like clockwork but quattro GmbH likes to take its time so rumors are suggesting the RS4 Avant could debut at the 2017 Frankfurt Motor Show before going into production in 2018.
