Ever since the Audi A5 mid-size executive coupe was born 3 years ago, reports of a high-performance RS variant have been teasing us.  Finally, the wait is over. 

Goog thing we checked our inbox today because we received an anonymous email containing 18 full-resolution photos of the Audi RS 5.  Simultaneously, we also received a tip from Australian Motoring blog Ausmotive.com which just posted the same photos which are sourced from a leaked brochure.  Either way, go put your bib on, because the drooling starts now.

No details about the powertrain or performance specs are revealed in the brochure. However, it does mention three types of seating and four wheel design choices.  Audi's 7-speed dual clutch S-tronic transmission is the only choice - no mention of 6-speed manual.  Also, no flat-bottom steering wheel is shown.

Speculation over which powerplant will drive the RS 5 has ranged from a massaged 3.0-liter supercharged V6 in the S4, 4.2-liter V8 and 5.0-liter V10 in the RS 6 to the range topping 5.2-liter V10 from the R8.  Horsepower has been logically guestimated between 450 PS (331 kW / 444 hp) and 550 PS (405 kW / 542 hp), essentially where the RS 4 leaves off with 420 PS (309 kW / 414 hp) and ending with the RS 6 and its 579 PS (426 kW / 571 hp).

The RS 5 will undoubtedly debut at the Geneva Motor Show in two weeks.  According to previous reports, the RS5 hits the streets soon after in July.
