GM Holden Reveals Future Racer Bathurst Time Attack Concept

As you all know, Holden is Australian automobile importer and a former automobile company. They have stopped manufacturing supercars in Australia, but the company is ready to deliver well-designed racers in General Motors’ worldwide strategy. Recently, to celebrate the 50th anniversary of its first Bathurst win, the GM Holden has revealed a beautiful ‘Time Attack Concept’ car for future.

The company’s design division from Melbourne has presented a concept that they call an apparently competent of leading a top speed of 480km/h and a great lapping Mount Panorama of 1:29.30s. The new concept is meant for a single-lap, against-the-clock Time Attack composition and not visualized for tracks including the Supercheap Auto Bathurst 1000.

GM Holden’s manufacturing organization implemented mechanical figures, drawing into developing technologies, with the form later constructed as a digitally-composed 3D concept. The latest designed concept car was displayed in the virtual system via video to showcase on Saturday, October 6 as a section of the 2018 Great Race show.

The extremely compelling concept has four electric motors generating 1340 horsepower and 3240 Nm of high torque, equipped into a carbon fiber and Kevlar structure. The car is expected to claim a high-performance of 0-100 km/h in just 1.25s and a top speed of 480 km/h. Earlier in 2011 promo event, GT3 car recorded lap of a 2m01.567s, whereas, the Jenson Button lapped the course in 1m48s in a McLaren Formula 1 car.

Richard Ferlazzo, Holden’s design director, claimes: “The virtual racer concept was formed employing high-level simulation technology. 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”.

Ferlazzo further added, “This concept is a digital advertisement for the advanced skills, capability, and technology of the GM Holden team. Concepts are always meant to push the boundaries but are even more impactful when they are feasible and this concept is plausible as an advanced racer of the future”.
