Abt mainly deals with Audi and the related primary Volkswagen Group brands—Volkswagen, Škoda, and SEAT—modifying them by using sports-type suspensions, engine power upgrades, lightweight wheels, aerodynamic components and more.

From 2014 to 2021, they ran a team under the Audi Sport banner in the FIA Formula E World Championship for drivers Lucas di Grassi, Daniel Abt and René Rast.

At the 2014 Beijing ePrix, di Grassi became the first driver to win an open-wheel motorsport race in an all-electric car.

In October 2002 an extension building was opened offering about 3,000 square metres (32,000 sq ft) extra of work space.

[13][14] Abt has taken much of their racing knowledge and adapted it for the street, making the company a successful tuner for the full Volkswagen Group line of products.

Abt Sportsline has announced in 2015 that they are going to introduce their new tuning program for the European Volkswagen Passat at the Geneva Motor Show.[when?]

While hosting the new Passat, their goal is to showcase a more aggressive kit that includes a front lip spoiler, revised side skirts, a tailgate-mounted spoiler, Abt-branded floor mats, 20- or 21-inch alloy wheels with Continental "sport-type" tires, optional mirror caps, sport springs and sports exhaust system, and a body kit that is more aerodynamic than the standard model.
