Audi A4 (B5) quattro Super Touring Car: Iconic Intake Sound & OnBoard at the Nürburgring!

This video is about two stunning Audi A4 quattro Super Touring cars I recorded during the 2025 and 2026 Oldtimer Grand Prix at the Nürburgring. The two cars are both ex-Emanuele Pirro chassis but unfortunately I don't know their exact numbers and consequently their full racing history. In any case the one with the fluorescent yellow details is now in the hands of Swiss racer René 'Aebi' Aeberhardt, while the other one is owned and driven by Austrian Markus Reich. Watch and hear it in action on the 'GP-Strecke' and jump on board with René for a couple of laps of the Nürburgring! (The scenes with the beautiful green meadows are from 2025, the others are from 2026... Recorded in the same period of the year, unfortunately😟) Super Touring, or Class 2, category was defined by the FIA for national touring car racing in 1993 and it was based on the "2 litre Touring Car Formula" created for the British Touring Car Championship (BTCC) in 1990. Super Touring replaced Group A as the norm in nearly every touring car championship across the world, but escalating development engine and aerodynamic costs, and the withdrawal of works teams caused the category to collapse in the late 1990s. They were required to be a minimum of 4.20 metres in length, with four doors, effectively requiring a small family saloon car as a minimum. No more than 2 litres engine capacity, maximum of six cylinders were permitted, and the engine was required to be naturally aspirated. Cars had also to retain the drivetrain layout of the road car they were based on so both two-wheel drive (both front and rear) and four-wheel drive cars were allowed. Super Touring formula was used in most national championships with different names: Super Tourenwagen Cup (shorten STW) in Germany, Campionato Italiano Superturismo in Italy, Championnat de France de Supertourisme, Australian Super Touring Championship and so on. Audi first entered Super Touring racing back in 1993 with the Audi 80 Competition quattro, with Frank Biela competed in the 1993 French Supertouring Championship, winning the title at the end of the season. With the same car Emanuele Pirro won the Italian championship the following year. The replacement of the Audi 80 Super Touring arrived in 1995. The new Class 2 weapon was based on the Audi A4 (B5) quattro which was characterized by immediate benefits over the 80, including a shorter overall body length, longer wheelbase and wider tracks, as well as a shorter front overhang. It was also so aerodynamically efficient that it's aero package helped overcome one of the car’s weaker areas: its engine. In fact the A4 Super Tourer was powered by a tuned 2.0-litre naturally aspirated four-cylinder engine, based on the same in-line, 16-valve used in the 80, which unfortunately was always underpowered next to the competition. In 1996 it probably never made more than about 290 hp, revving all the way up to the regulatory limit of 8,500 rpm. All the power was delivered through a 6-speed sequential transmission to the permanent all-wheel-drive system. Tipping the scales at roughly 1,040 kg, it was also slightly heavier than its two-wheel-drive rivals to balance out the quattro system, but the trade-off was more than worth it thanks to the immense grip obtained on corner exit and high-speed stability. The car debuted in the German Super Tourenwagen Cup and was immediately successful. By 1996, the A4 quattro had one of the most dominant seasons in touring car history, claiming seven national championship titles across the globe, including the top three and most demanding British Touring Car Championship with Frank Biela, the German STW with Emanule Pirro and the Italian Superturismo with Dindo Capello. The other title wins came from Spain, South Africa, Belgium and Australia a record for touring car racing. The all-wheel-drive advantage was so huge that weight penalties were soon introduced for 1997, leading to a complete ban on 4WD in Super Touring by 1998. Forced to convert the A4 to front-wheel drive, Audi faced tough competition from purpose-built FWD rivals. Chassis and engine placement weren't ideal for a single-axle drive, making the car much trickier to balance. Despite taking some extra wins and a final German STW title in 1999 with Christian Abt, the FWD transition marked the closing chapter of Audi's iconic Super Touring era. ➡️ Stay tuned for future Super Touring Revival dates: Instagram:   / supertouringrevival   0:00 Mix OnBoard & External Scenes 2:41 Paddock & Warm Up 5:32 Pit Exit 6:41 External Scenes - pt. 1 8:54 One Lap OnBoard 11:00 External Scenes - pt. 2 13:19 Another Lap OnBoard 15:14 Final Mix #AudiA4 #AudiA4SuperTourer #SuperTouring Huge thanks to my friends and youtubers ‪@Italiansupercarvideo‬ & ‪@sportcrash71‬ for the great collaboration done recording this car!
