Audi appears to have high hopes for the 2016 TT RS as the model has been spied being benchmarked against the Lotus Evora, Mercedes-AMG A45, and the Porsche Cayman GT4.

Since the drivers were forced to travel up and down the same roads before swapping cars and repeating the trip, our spy photographer was able to snap dozens of photos when they stopped to take notes during changes. As a result, we can see the high-performance model will have a sportier front bumper, honeycomb mesh grille inserts, and lightweight alloy wheels that are backed up by a high-performance braking system with "RS" branded calipers.

This particular prototype isn't production ready, but previous prototypes have shown the model will also have a new rear bumper and a dual exhaust system.

Audi is keeping specifications under wraps but the model is expected to use a turbocharged 2.5-liter five-cylinder engine.  The output remains mystery but rumors have indicated anything from 375 bhp (380 PS / 279 kW) to more than 401 bhp (407 PS  /300 kW).  If the latter figure pans out, it is believed the car could accelerate from 0-62 mph (0-100 km/h) in four seconds or less.

The TT RS is expected to debut at the 2016 Geneva Motor Show before going on sale later that year.
