Vauxhall set an average speed of 125mph over 3000 laps of Millbrook
The test was carried out on Millbrook's two-mile banked circuit
Two 2.0-litre CDTi Vauxhall Astras were used for the record attempt
A team of 12 drivers each took four-hour stints in the cars
The record has yet to be ratified by the FIA and MSA
Vauxhall says it is 'quietly confident' it has set new records
The previous record stood at 100.2mph
One tyre change per car was needed, but no mechanical problems were reported
Vauxhall has set a new record for the average speed achieved on the Millbrook banking over 24 hours.
While the data has yet to be ratified by the FIA and MSA, Vauxhall says it recorded an average speed of 125mph over 3000 laps of the two-mile banked circuit over 24 hours.
Two 163bhp 2.0-litre CDTi Vauxhall Astras completed the challenge, using 12 drivers each taking four-hour stints. Vauxhall says that during the test both cars required a new set of tyres, but no other mechanical interventions were needed.
The company now aims to enter its time as a challenger to two existing speed records, the 1600-2000cc forced-induction diesel production car classes run by both the FIA and the MSA. Previous records had already been set around the banking over one, six and 12 hours.
While the national 24-hour record has stood at 100.2mph since 1992, a world record has not been established before.
Vauxhall says it has attempted to either set or break a combined total of 18 records with the challenge.
