The car itself – a Corrida Red OCTAVIA vRS 2.0 TSI – was originally destined to join the ŠKODA UK press fleet before being requisitioned for the Bonneville project. Although based on a production OCTAVIA vRS 2.0 TSI, the ‘Bonneville special’ required extensive modification for the record attempt. Under the regulations set out by the Southern California Timing Association, only a certain number of modifications were permitted. Adding to the challenge was the fact that the OCTAVIA’s 2.0 TSI engine was so new at the time that very few motorsport or high performance upgrades were available from external suppliers.
Working to an almost impossibly tight deadline, key upgrades included an injection system altered to deliver more fuel to the engine (eight injectors), and a cooling system which benefited from the addition of a 10-litre radiator. The longer-geared transmission from an OCTAVIA GreenLine was also installed to enable a higher top speed, while the traditional brake discs and calipers were removed and replaced by a parachute to ensure the car could safely stop on the salt surface. Operated by a lever in the cabin, this had the added advantages of reducing excess drag, unsprung weight and friction.
The Milton Keynes-based ŠKODA UK team behind the racer spent the days leading up to Bonneville’s famous Speed Week putting the car through a rigorous dyno programme with the assistance of performance software and tuning outfit specialist REVO Technik.
The record-breaking OCTAVIA vRS Bonneville Special forms part of the ŠKODA UK heritage fleet that features a collection of ground-breaking models dating back to 1929.
