700HP Audi RS6 by ABT Sportsline
The tuning package matches or exceeds the MTM RS6 Avant, released just a couple weeks ago. Though Abt hasn't released performance specs for the tire-shredding wagon, the MTM version manages the sprint to 60mph (96km/h) in under five seconds and is reportedly capable of speeds in excess of 187mph (300km/h), so the Abt RS6 should post similar numbers.
Among the extensive list of improvements to the car, Abt has removed the electronic speed limiter, re-tuned the ECU to boost power, outfitted a new aerodynamics package that includes a carbon fiber front lip spoiler and rear diffuser, a wide range of custom alloy wheels, custom Abt-branded floor mats and shift knobs, plus a specially-tuned rear muffler with four exit pipes. As usual with Abt's tuning kits, the individual elements are highly customizable and most can be had individually or as a package.
Pricing for the speed-limiter removal starts at €1,500 ($2,200) and the ECU tuning will cost €4,900 ($7,200), but both pale in comparison to the car's base price of €107,800 ($158,000).
