ABT Sportsline have a whole bunch of cool cars to present at the 2017 Geneva Motor Show, including a bonkers Audi RS6 Avant. Christened the Audi RS6+, it will be produced in just 50 examples, and all of them will come with 705 PS (695 HP) and 880 Nm (649 lb-ft) of torque, courtesy of a power boost that uses an in-house developed control unit. 

This means that the super estate now has 100 PS (99 HP) and 130 Nm (96 lb-ft) of torque more than the stock car. ABT have yet to release any acceleration numbers, but the standard model needs just 3.7 seconds from naught to 100 km/h (62 mph), and 12.1 seconds from 0 to 200 km/h (124 mph).
