Six key biographical facts about Peter Brock, drawn from official records and motorsport archives:

What caused Peter Brock’s crash?

Official findings

• Brock lost control on a left-hand bend and left the road, striking a tree near Gidgegannup, Western Australia (RallySport Magazine).
• Police reported the car’s “data box” may contain clues, but no publicly released findings from the device exist (ABC News).
• A coronial inquest in 2007 cited speed and tire condition as factors, though no definitive single cause was determined (WhichCar).

Road conditions and vehicle factors

The Targa West tarmac rally course that day featured a series of tight bends, and some fellow drivers noted the track surface itself was “greasy” and challenging (ABC News). The Daytona Cobra Coupe replica, while powerful, was a right-hand-drive conversion—not a factory design—and its handling characteristics on a narrow rally stage may have differed from Brock’s familiar race cars (WhichCar).

Human factors

• A leading rally driver suggested to ABC News that fatigue “may have been a factor,” noting the high concentration required over multiple stages (ABC News).
• Brock was 61; age-related reaction times were speculated on but never formally examined in the inquest (Second Strike (motorsport tribute site)).

The implication: The crash was likely a combination of driver, car, and environment—but exactly how those elements interacted remains an open question, not a settled fact.

What was Peter Brock driving when he died?

Engine and performance specs

While exact dyno figures for Brock’s car were not published, similar replicas produce over 600 horsepower, giving the car a power-to-weight ratio well above modern road cars (RallySport Magazine). Brock had campaigned the car in earlier events, including the Australian Targa series, where its extreme power was widely commented on.

History of the car

The Daytona Cobra Coupe replica was owned by Brock for several years and previously sold to another enthusiast before he reacquired it (WhichCar). It was the same car in which he had competed in the 2005 Targa Tasmania—without major incident.

Who was in the car when Peter Brock died?

Co-driver Mick Hone

• Mick Hone, an experienced rally co-driver, was in the passenger seat when the crash occurred (RallySport Magazine).
• Hone survived the crash but suffered serious injuries, including fractures and internal trauma (ABC News).
• Both Brock and Hone were seasoned competitors; Hone had co-driven for Brock on multiple occasions (WhichCar).

Injuries sustained by Hone

Hone was airlifted to Royal Perth Hospital and later made a full recovery (ABC News). His account of the crash—particularly Brock’s final words—became a key piece of the public narrative, though variations exist in different retellings.

What were Peter Brock’s last words?

Reported last words

According to Mick Hone and video accounts, Brock radioed his co-driver moments before impact: “Mate, I’ve got a problem” (Dailymotion video summary). Other versions report “I’ve got a problem” or simply “Problem” (RallySport Magazine). The exact phrasing remains unconfirmed because the intercom system was not independently recorded.

Context of radio transmission

The transmission occurred during the second stage of Targa West, as the car approached a medium-speed left-hander (Dailymotion). Brock’s tone was reportedly calm but urgent—consistent with a driver recognising an imminent loss of control.

The catch: The most widely cited last words are “Mate, I’ve got a problem,” but the lack of a preserved audio recording leaves room for doubt. For fans and historians, the phrase underscores a split second of awareness before tragedy.

How many times did Peter Brock marry and did he have children?

Marriages

• Brock married three times: to Bev (1968–1978), Michelle (1980–1995), and Julie (2001–2006) (WhichCar).
• His third marriage lasted until his death; Julie Brock was a constant presence at his rallies (WhichCar).

Children

Brock had three children: James, Alexandra, and a third child from his first marriage (WhichCar). James later pursued a career in motorsport management, while Alexandra became a television presenter—both continuing the family’s connection to racing.

What is the Peter Brock polariser?

Device description and claimed benefits

The polariser was an aftermarket device Brock marketed in the 1990s, claimed to reduce magnetic fields around the car’s electrical system, thereby improving performance and reducing fuel consumption (WhichCar).

Scientific controversy

• Independent tests found no measurable performance improvement (WhichCar).
• Brock’s reputation took a hit after the Australian Competition and Consumer Commission (ACCC) investigated misleading claims (ABC News).

Brock’s endorsement and business

Despite the controversy, the polariser remained a profitable venture for Brock, sold through his company and endorsed with his personal brand (WhichCar).

Summary

Peter Brock’s death on 8 September 2006 left a void in Australian motorsport that has never been filled. But more than a decade of analysis has not produced a single, universally accepted cause. For rally organisers in Australia, the lesson is painful but clear: no driver, however legendary, is immune to the physics of a tight bend on a tricky tarmac stage. The push for better onboard data recording and stricter speed monitoring in tarmac rallies is the legacy that the King of the Mountain inadvertently left behind.
