The Audi A5  has always been handsome. Rather than being pretty, it has a more masculine look, like something that Jon Hamm would probably drive. The best way to make a great-looking car better is to give it more power, which Audi gladly did with the S5  . More is never enough though, so Audi cranked the performance up even more on the RS5  .

For some buyers, the RS5 was fine, but others still needed more performance. With no RS5 Plus in the pipeline, those owners are are forced to turn to tuning companies. One such company to offer a performance tune for the RS5 is Senner Tuning out of Germany. Offering more than a 50-horsepower bump over the stock RS5, as well as a suspension tune, a new exhaust, new wheels, and an appearance package, there’s no mistaking the Senner Tuning RS5 something that’s far from run-of-the-mill.

While the stock RS5 Coupe makes a very healthy 450 horsepower, the RS5 Coupe by Senner Tuning makes an even better 504 horsepower. An increase in 54 horsepower doesn’t just come from an ECU tune though. Senner has modified the intake and included a custom, in-house sports exhaust as well. Devel  oping the new exhaust themselves, Senner was able to include separate traveling, race, and sports settings that can be accessed via Audi’s MMI  interface, allowing the driver to decide exactly how loud the exhaust should be.

The suspension gets a set of Bilstein coilovers that improve handling and allow the driver to independently adjust both push and pull dampening. Finally, a set of 20-inch, three-piece Competec wheels are included at all four corners in high-gloss black.

Matching the gloss black wheels are gloss black exhaust tips, as well as a black rear spoiler and grille. All the chrome trim, including the four-ring Audi badge, is also black. To complete the visual changes, Senner added "signal yellow" strips to the front spoiler and rear diffuser, and they painted the brake calipers to match. Signal Sellow Senner graphics are also included in front of the rear wheels.

While the extra 54 horsepower is much appreciated, and the adjustable exhaust is a nice touch, the overall package seems a bit too "loud" for an Audi.

Senner Tuning says pricing should be right around €23,550.

Introduced in 2010 and updated in 2012, the RS5 is Audi’s ultra-high performance version of its A5 coupe. Based on the MLP platform that the A6  is built on, the A5 is actually three inches shorter than the A4. Available only with Audi’s 2.0-liter, four-cylinder TFSI engine, the A5 makes 220 horspower and 258 pound-feet of torque.

To bring the performance of the A5 up to proper RS levels, Audi shoehorned its 4.2-liter, V-8, FSI engine into the RS5. The larger engine more than doubled the A5’s horsepower, producing 450 horsepower, as well as 417 pound-feet of torque. All that power is routed through a seven-speed, dual-clutch transmission and transferred to the ground with the help of Audi’s quattro  all-wheel-drive system. With the power being sent to all four wheels, a run from 0 to 60 mph can be done in 4.5 seconds, and with a long enough straightaway to keep going on, the RS5 Coupe will top out at 174 mph.

For reference, the 2015 BMW M4 Coupe  will top out at the same 174 mph, but opting for the dual-clutch transmission will cut its 0 to 60 time down to 3.9 seconds. Pricing for the RS5 Coupe starts at $69,600, while the RS5 Convertible starts at $77,900, making them both several thousand dollars more expensive than their BMW M4 competition at a respective $64,200 and $72,500.
