Audi introduced the S1 Quattro at the end of 1984. According to the requirements of Group B, 200 classification cars designed for Sport Quattro street traffic were produced and 20 B-group racers loosely based on them. The S1 Quattro debuted in Jyväskylä Suurajot in 1985. Audi’s racing team was one of the most impressive ever: Hannu Mikkola, Walter Röhrl, Michelle Moyton and Stig Blomqvist.
The Audi Sport Quattro S1 Evocation respects the rally hegemony of the S1 with remarkable precision. The car is a show racer built by Riku Tahko Rally Consulting for Secto Automotive Labs.
The Audi’s car body was found in early 2022 from Sweden. The goal was to get the car ready for Secto Rally Finland 2022. The body of the Sport Quattro S1 Evocation is made in the same way as Audi made factory rally cars in the 1980s: The body combines the front of the Audi 80 and the rear of the Sport Quattro. The factory made the racers by combining them, because the 80 sedan model’s windshield was taller than the Sport Quattro’s and thus reduced reflections. The body of the S1 is 32 centimeters shorter than the Sport Quattro, and the end result is therefore more agile to handle.
The body of the car had already been prepared in Sweden. The car came with Audi’s 5-cylinder 2.2-liter turbo engine blank built for drag race competitions. The body also contained the racer’s sub frames for powertain.
Audi Sport Quattro S1 Evocation was built by RTRC, i.e. Riku Tahko Rally Consulting Team. The goal was to build a racing car intended for show rally runs and Hill Climbs. Externally identic to the B-group S1 rally car, but a car which runs on modern P1 Fuels fossil-free eFuel.
Gearbox was updated for a modern 6-speed sequential gearbox. The handbrake was upgraded to hydraulic, which locks the rear wheels. The front and rear axles have traditional disc locks and the gearbox has a traditional differential lock. Instead of gravel rally stages, the chassis and suspension diametrics and specifications are designed especifically for demonstration driving on tarmac and, for example, with Hill Climb competitions in mind.
The engine, transmission and KW -shock absorption work with fossil-free Lubrican oils.
The five-cylinder equipped with a huge Precison turbocharger only wakes up after 5,000 rpm’s, but produces 750 horsepower at 2 bar boost pressure and around 1,000 horsepower at 3.3 bar boost pressure. Fuel is given by mechanic fuel pump with pressure regulator and fuel injection controlled by Max Ecu system. The end result is fierce and wild, “aim and shoot”, which requires hands and handling skills, but enables amazing four-wheel drifting.
The car has the electrics of a modern rally car and the use of the supercharger can be adjusted with the Boost and Antilag buttons on the steering wheel. The dashboard has been kept simple and period correct, but all important information for driver is available on Tremondi screen.
The car has modern safety devices approved for competition use, such as FIA approved seats and 6-point belts. The car has a modern Tilton pedal box.
The S1 Evocation was completed in time for the 2022 Secto Rally, where Matias Henkola opened the rally by driving it on the Harju Stage. At the same stage Hannu Mikkola drove an S1 Quattro for the fastest time in 1985.
The S1 Evocation has already been starred at numerous of events and was also used in Killeri stage at the Jyväskylä winter rally. At that time, the driver was the father of recent world champion Kalle Rovanperä, the rally legend Harri Rovanperä.
This car is not a typical B-group garage queen replica, but really a remarkable and unique thoroughbred but useable race car for the next owner to drive and enjoy.
The car has been built with longevity and ease of use in mind. Upkeep and maintenace regardless of costs. The car will be sold including it’s service protocol.
