Peter Geoffrey Brock (26 February 1945 – 8 September 2006), known as "Peter Perfect", "The King of the Mountain", or simply "Brocky", was an Australian motor racing driver. Brock was most often associated with Holden for over 35 years, although he raced vehicles of other manufacturers including BMW, Ford, Volvo, Porsche and Peugeot. He won the Bathurst 1000 endurance race nine times, the Sandown 500 touring car race nine times, the Australian Touring Car Championship three times, the Bathurst 24 Hour once and was inducted into the V8 Supercars Hall of Fame in 2001. Brock's business activities included the Holden Dealer Team (HDT) that produced Brock's racing machines as well as a number of modified high-performance road versions of his racing cars.
Peter Brock was born at the Epworth Hospital, Richmond, Victoria, the son of Geoff and Ruth Brock (née Laidlay). The family lived in the country town of Hurstbridge (now an outer suburb of Melbourne) and Brock continued to live there throughout his life. He attended Eltham High School in Eltham, Victoria. His first car was an Austin 7 that he bought for £5 (A$10). He claimed that his driving skill improved at this point of his life because the car did not have brakes (or a body, which was removed with his father's axe).
Brock was drafted into the Australian Army in 1965 and spent his two years of National Service stationed at the Blamey Barracks near Wagga Wagga in New South Wales. During his time in the army, Brock was against the federal government's plan to send conscripts to Vietnam. Brock was in the Medical Corps where he often served as an ambulance driver. According to his brother Lewis, Brock and his mates used to race the ambulances around the base. Although they did not know each other at the time, also stationed at the Barracks from 1965 to 1967 was a young Dick Johnson who from the 1980s would go on to be one of Brock's chief touring car rivals.
It was while on leave from the army in 1966 that Brock first visited Bathurst to watch the 500-mile production car race that was to become the Bathurst 1000. It was after watching the race that he decided that he wanted to become a race driver when he left the army. His brother Phil also became a racing driver, and co-drove with his brother in the Bathurst 1000 on two occasions.
During his early career Brock raced some "wild and woolly" creations including the famous blue 6-cylinder Holden-powered Austin A30. Brock rose to public attention in touring car racing.
Brock made his debut at Bathurst in the 1969 Hardie-Ferodo 500 in a Holden HT Monaro GTS 350 alongside Des West, with the pair finishing third behind their winning HDT teammates Colin Bond and Tony Roberts. He won the Bathurst 500 for the first time in 1972 (the last year the race was run over 500 miles and the last year in which driving solo was permitted).
Brock would win the event a total of nine times between 1972 and 1987, a feat that has not been equalled. His 1979 win was remarkable in that he and co-driver Jim Richards claimed victory by six laps, a record that, due to changes in race regulations introduced in the mid- to late 1980s, most notably the introduction of the Safety Car in 1987, may never be broken, and broke the circuit lap record for touring cars on the 163rd and final lap of the race (the record would stand until Brock himself broke it in 1982). Brock had tried to set the lap record on the final lap of the 1978 race, but he was inadvertently baulked by the Alfa Romeo of Ray Gulson through The Dipper. In 32 starts at Bathurst, he claimed pole position a record six times (1974, 1977, 1978, 1979, 1983 and 1989), with all bar his 1989 pole in a Ford Sierra RS500 being for Holden. Brock also sat on pole for the 1997 V8 Supercars race but the time was set by his co-driver Mark Skaife. His record at this race earned him the popular nickname King of the Mountain.
Peter Brock also won the second (and last) Bathurst 24 Hour race in 2003 driving a 7.0L V8-powered Holden Monaro 427C for Garry Rogers Motorsport. Brock won the race, which although not the Bathurst 1000, he regarded as his tenth Bathurst win driving alongside V8 Supercar drivers Greg Murphy, Jason Bright and Todd Kelly. The #05 Monaro won the race by less than half a second from the 2002 race winning GRM Monaro 427C driven by Nathan Pretty, Garth Tander, Steven Richards and Cameron McConville. The two Monaros finished 12 laps in front of the third-placed Porsche 996 GT3 RC of Peter Fitzgerald, Paul Morris, John Teulan and Scott Shearman.
Along with his record at the Bathurst race, Brock also claimed victory in the traditional lead up race to Bathurst, the Sandown 500, nine times, including a string of seven consecutive wins from 1975 until 1981. He won a total of 37 races during his career in the Australian Touring Car/V8 Supercar championships, a record only eventually equalled by Mark Skaife in 2006 and beaten in 2007.
Brock had a brief foray into Open wheel racing when he raced a Ford powered Birrana 273 to 8th place in the 1973 Australian Formula 2 Championship. Although he had some minor, non-championship wins in the car, his best placing in the national championship series was second behind series champion Leo Geoghegan in Round 2 or Oran Park in Sydney. Brock's HDT boss Harry Firth later told that he let Brock race the Birrana to get formula racing "out of his system". Later in early 1984, Brock tested a Ralt RT4 with a view to possibly driving one in the 1984 Australian Drivers' Championship and the end of year Australian Grand Prix (which at the time were run to Formula Mondial rules), and put in some competitive lap times at Calder Park. However, he later decided that with the road car business, touring car commitments and the planned Sports Car races at Silverstone and Le Mans, he simply could not devote enough time to the project to make it worth doing.
Brock and the Holden Dealer Team worked in partnership, with full factory approval and assistance, to produce a number of high-performance modifications to the Commodores under existing CAMS Group C regulations from 1980 to 1987. Some of these were HDT "homologation specials", one step away from race cars. It was around this time that Brock began his run of six Bathurst 1000 wins in seven years with a pair of hat trick wins from 1978 to 1980 (with Jim Richards) and 1982 to '84 (with Larry Perkins and John Harvey), including his record-breaking six-lap victory in the 1979 event.
While Brock was always typecast in a Holden, he did have 'brief flirtations' with other makes in touring car racing. After his 1987 Holden split, he campaigned a BMW M3 in 1988, becoming the official BMW Australia backed team for the year (his only win in the BMW would be in the 1988 Pepsi 250 at Oran Park), before driving a Ford Sierra RS500 in 1989 and 1990. As the turbo-charged Sierras were the Group A cars to have at the time it was seen as a logical move to return to the front end of the field.
During 1988 Brock also campaigned a V8 Ford XF Falcon in the Calder Park Thunderdome-based AUSCAR series, though unlike touring car rivals such as Jim Richards, Allan Grice and Brad Jones, Brock's foray into Superspeedway racing was brief.
With the increasing costs of running two Sierras, and with the teams technical support from the UK-based Andy Rouse also stopping thanks to Rouse moving to drive for Toyota, Brock returned to driving a Holden in 1991, teaming with former HDT co-driver Perkins (who had left the HDT in mid-1985) to run a pair of VN SS Group A Commodores. The association with Perkins Engineering only lasted for one year, though Brock continued to run the ATCC driving in Commodores.
A further flirtation away from Holden was in 1994 when he raced a Volvo 850 in the one-off Eastern Creek 12-Hour. He also competed for the same Volvo Dealer Racing team in the Australian Super Touring Championship in 1996, finishing 6th in the championship with a best finish of second in Round 7 at Lakeside in Brisbane.
