Check out world’s first (and only) Audi RS6 Allroad

The improvised, homegrown Audi wagon has been built from two cars, and is now on sale with a top bid just under €18,000.

Based on a 2003 Audi A6 Allroad (see video), the car ditches its 2.5-liter turbo diesel and automatic transmission in favor of a 4.2-liter turbocharged V8 and manual gearbox. The engine stems from an RS6 and produces 450 PS (444 hp / 331 kW) and 580 Nm (428 lb-ft) of torque. The seller claims you can use a software upgrade to get 510 PS (503 hp / 375 kW).

The all-wheel drive system is still present, but the car is no longer as good off-road due to a missing air-ride suspension. Instead, it rides on aftermarket springs by KW, RS6 suspension parts, RS6 brakes, and 20-inch wheels shod in 255/35 tires.

Found inside are a new dashboard and Recaro bucket seats, and the seller promises to replace the cracked leather trim with black Alcantara as soon as possible.

All modifications are reflected in the documents coming with the car and made street-legal, according to the owner. The mileage reportedly made 265,000 kilometers (nearly 165,000 miles) prior to the tuning, but did not exceed 2,000 km (1,240 miles) after it.
