Efijy is one of Holden’s most historically significant concept cars and will take centre stage at Meguiar’s MotorEx Melbourne 2014 (July 19-20). This phenomenal machine will be showcased in a special display celebrating Holden’s design excellence and rich, 66-year history in producing iconic Aussie vehicles. Here is a quick rundown on one of the star attractions to see at the show…

The baby of Holden’s styling and design guru, Richard Ferlazzo, the internationally-renowned Efijy is widely considered to be the world’s best hot rod. Hard to argue considering it was awarded North American Concept Car of the Year in 2007 and took out the coveted Hot Rod magazine, 2006 Hot Rod of the Year! The HOK Soprano Purple, pillar-less coupe was built in-house at Holden’s design studio and engineering department – with extensive assistance from around 20 of Holden’s key suppliers. Although Efijy had Head Office approval, many of the dedicated team of enthusiasts within Holden that built this iconic machine, did so after hours.

Riding on a lengthened C5 Corvette chassis, the all-fiberglass body is powered by a 6.0-litre LS2 V8 topped with a Harrop supercharger. Rated at a healthy 480kW (643hp), it’s easily capable of shredding the 22-inch tyres and the Corvette four-speed auto transaxle also needed beefing up. The inside of this retro-rod is magnificent; trimmed in sumptuous tan leather, it effortlessly blends 50s, art-deco styling with modern, high-tech gizmos. A timeless creation like no other.

Although it was constructed to have a bit of fun and celebrate the 50th birthday of Holden’s FJ, it was still in essence a concept car. As such, Efijy showcased a number of emerging technologies including adjustable shock absorbers, push-button, electronic gear selection, touch-control LCD screen, hard-drive audio/video, navigation, proximity sensing door opening and LED lighting that incorporated fan-cooled, LED headlamps – all cutting edge stuff when it debuted at the 2005 Sydney International Motor Show.

The fully-functional Efijy also went on a bit of world tour. Richard Ferlazzo, Design Director of GM Holden, drove it in the 2007 Woodward Dream Cruise, it took centre stage on the GM stand at the 2007 Detroit Motor Show and wowed the crowds at the Dubai Motorshow.
