HDT Special Vehicles: Brock’s 1980s baby

HDT Special Vehicles: Brock’s 1980s baby

We reflect on the late Peter Brock’s production car business plans

On the showroom floor Holden was in a big battle with Ford as the clock struck 1980, Kingswood killed and Commodore created with the larger Falcon ultimately overtaking it in national sales for the first time ever all within two years.

Meanwhile on the racetrack Peter Brock had won Bathurst four times in eight years between 1972 and 1979. His fifth win in 1980 would mark the switch from steering Toranas to driving the VC Commodore, a year in which the man fast becoming King of the Mountain would also buy the Holden Dealer Team (HDT) he had been racing for.

He would also be given blessing from bleeding Holden to create road-going ‘homologation’ specials of the Commodore, and so HDT Special Vehicles was born. Set to be sold through select Holden dealerships, they were also a way of making money to go racing after The General pulled factory support two years earlier.

HDT VC CommodoreThe VC HDT was based on the luxury Commodore SLE complete with headlight wipers, but with its own 15-inch Irmscher wheels, subtle bodykit including ducktail rear spoiler and Momo leather steering wheel inside.

Power from the 5.0-litre V8 was taken from 126kW to 160kW and a 500-unit batch was built in red, white or black – livery of tobacco company Marlboro, Brock’s main sponsor at the time.

HDT VH CommodoreBy 1982 the following HDT was the VH Commodore SS Group 3, a now wilder model based on the sports model grade newly introduced to the Holden lineup. The raised power bulge matched the raised power output of 184kW.

It was the VK Commodore Group A of 1985 that would earn the nickname Blue Meanie for its Formula Blue paint. Signed by Brock on the front three quarter panel and dashboard, the 5.0-litre was downsized to 4.9 litres (to meet Group A racing regulations) but substantial other cam and carb modifications leveraged power to a then-heroic 196kW.

HDT VKGroup A SSBy 1986 the relationship between Brock and Holden began to tense. HDT SV was approved to build the Commodore SS Group A and Group Three models in similar vein to the preceding VK, but the boundaries were pushed with the Director unveiled in February the following year, making up to 231kW in ‘stroker’ 5.6-litre spec.

Brock had peddled a device called the Polarizer to be installed in Commodores, the now infamous box of crystals that apparently aligned the car’s molecules to improve handling in conjunction with lower tyre pressures. Holden did not approve, and various Group A models were fitted with or without the device; if they weren’t, they wouldn’t get Brocky’s signature.

HDT VK directorIt was an indication of his persistence that Brock not only pushed forth with the polarising Polarizer but attempted to forge an Opel-derived independent rear suspension set-up for the 1987 VL Director series also without Holden approval. And so after 4246 vehicles produced by HDT SV a very public divorce ensued with The General.

From the ashes came attempts by Brock to sell Commodores separate from Holden, but the brand also found a new homologation partner – Tom Walkinshaw Racing (TWR) and Holden Special Vehicles was born with the debut of the wild ‘Walky’ of the same year.

Brock MaverickBrock eventually went on to briefly tune (gasp) Falcons dubbed Executive Performance (EP) editions of the EA and even a Brock Maverick (itself already the Ford version of Nissan’s Patrol). For Holden fans it was even more unthinkable that his equally brief foray into tuning Russian-made Lada Samara hatchback, just to keep his company from sinking.

He went on to advertise the Volvo 850 R (having steered it in the Bathurst 12-Hour in 1994 and 1995 and driven the Super Touring version in 1996) but by the late-'90s he was back in Holden commercials beside Deborah Hutton; for the 2001 Sydney motor show signing autographs beside the reborn Holden Monaro.

Murky business matters of the 1980s had mended over time, his fans never polarised by the man dubbed Peter Perfect.
