Audi won't offer a Plus variant of the RS3 Sportback

2015 Audi RS3 Sportback

According to a recent report, Audi will not offer a high-performance RS3 Plus.

In an interview with Top Gear, Quattro GmbH technical development boss Stefan Reil said "We are at the limit of the size of the turbocharger. We have durability limits and our warranties to consider." 

While the engine can technically develop more power - as shown by the 525 PS (386 kW) A3 clubsport quattro concept - Reil said it would require the use of a larger turbocharger and a "lot of engineering."  This seems to suggest we'll have to make due with a turbocharged 2.5-liter engine that develops 367 PS (270 kW) and 465 Nm (342 lb-ft) of torque.
