STR1

STR1

STR1 was the first single-seater in Toro Rosso’s history. It competed in the 2006 Formula 1 World Championship, with Vitantonio Liuzzi and Scott Speed in the cockpit, whilst Neel Jani came onboard as the third driver. In 2004, Red Bull bought the Jaguar F1 Team based in Milton Keynes, UK, renaming it Red Bull Racing.

The following year, Red Bull’s Dietrich Mateschitz bought the Faenza-based Minardi F1 Team and renamed it Scuderia Toro Rosso. It was the beginning of a new era. It was the first chapter of a new story and it all started with our first car: the STR1.

The car had a lot in common with the previous year’s Red Bull Racing RB1.

Technical specification

The monocoque of the STR1 was made of carbon fibre and was powered by the 2,998 cc Cosworth V10 engine, equipped with a semi-automatic longitudinal seven-speed aluminium gearbox. Toro Rosso was the only team on the track in 2006 to still use a V10 engine (the other teams ran with the new 2400 cc V8 engines) limited to 16,700 rpm and with an air intake restricted to 77mm in diameter.

The Toro Rosso STR1 had a pushrod suspension both front an rear. It was fitted with AP brakes with carbon discs and used Michelin tyres.

STR1 results

It made its debut on track at the Barcelona winter test on February 9, 2006. The car performed well, especially in the first part of the season. The STR1’s first race was also the first Grand Prix for Toro Rosso: the 2006 Bahrain GP.

The engine, albeit limited by the new regulations governing the introduction of the new V8, proved to be reliable and allowed the Faenza team to secure reasonable results. The best one came courtesy of Vitantonio Liuzzi: the Italian managed to give the team its first points, thanks to an eighth place finish in the United States Grand Prix that year. At the end of the season, Toro Rosso was ninth in the Constructors’ Championship.
