Audi RS cars are some of the most powerful vehicles ever offered by Audi. The Audi RS5 5.0 TFSI quattro, for instance, is more powerful than the Audi S8 5.2 FSI quattro. Available for limited time scales, on a restricted model range, these "RS" models are wholly designed, developed and produced in-house by Audi AG's high performance private subsidiary company, quattro GmbH, at its Neckarsulm factory, and usually have a wider bodyshell (sometimes informally referred to as 'widebody') to allow for a wider front- and rear-axle track.
All "RS" cars pioneer some of Audi's latest and most advanced technology and engineering prowess, therefore, "RS" cars could be described as "halo vehicles".
