UPDATED: Holden builds virtual time attack concept

BUILT to coincide with the 50th anniversary of Holden’s first win at Bathurst in 1968, GM Holden’s design team has used virtual reality to build a stunning time attack concept racer.

Unlike the conventional format of the current endurance race cars, the Holden Time Attack Concept racer is envisioned as a single-lap tearaway, pitted against the clock. This type of racing is commonly known as Time Attack in motor sport circles.

The Holden Time Attack Concept racer was developed entirely virtually, using sophisticated simulation technology and driven by the world-class expertise within GM Holden’s Melbourne Design Studio.

“The technology we employ today has transformed the way we design cars. We have the ability to simulate a car’s appearance, technology and dynamics in convincing animations, which enables us to deliver better designs in a shorter time,” GM Holden’s Design Director, Richard Ferlazzo explains.

Holden has a long and storied history of creating crowd-pleasing concept vehicles dating back to the iconic Holden Hurricane concept of 1969, with traditional motor shows the typical platform for debuting them to Australia.

As times have changed, so has Holden’s approach to developing concept vehicles.

“With the realism and detail achievable through modern technology, I felt we could still deliver uniquely Holden concepts via virtual technology and digital media,” Ferlazzo said.

Ferlazzo set a challenge for his talented design team to explore a futuristic race car using the latest emerging technologies around the world and was impressed with the proposal from Lead Designer, Ewan Kingsbury.

“Ewan perfectly captured the essence of what we wanted to achieve; an expressive, futuristic design which also displays innovative engineering solutions,” he said.

The concept was developed with technical input from GM Holden’s Engineering team and the final design was validated with a digitally-printed 3D model.

The finishing touch is the stunningly realistic video, created by GM Holden’s in-house Design Visualisation team, of the Time Attack Concept racer lapping the iconic Mount Panorama circuit (above).

The video debuted during the telecast of The Great Race today (Saturday October 6). The Holden Time Attack Concept has some impressive specs, as detailed below.
