2005 Holden Efijy Concept

The 2005 Holden Efijy Concept is an Australian show car created as a tribute to the iconic 1953 Holden FJ, one of the country's most beloved early models. It was first revealed at the Australian International Motor Show in 2005 and instantly drew attention for its bold design and powerful engineering.

The Efijy was designed entirely in-house at GM Holden’s Australian design studio, led by chief designer Richard Ferlazzo, who originally sketched the concept in 1989. Painted in a striking “Soprano Purple” with billet aluminum accents, the car takes classic hot rod styling to a new level with modern technology and craftsmanship.

Underneath its sleek, pillarless fiberglass body is a lengthened Chevrolet Corvette chassis, stretched by 26 cm to support the Efijy’s 5.2-meter length. Power comes from a 6.0-liter LS2 V8 engine fitted with a Roots-type supercharger, delivering 644 hp and 560 lb-ft of torque. The powertrain is paired with a rear-mounted 4-speed 4L60E automatic transmission and a limited-slip differential.

Efijy also features a fully custom stainless steel exhaust, adjustable air suspension, and large, polished wheels—20 inches in the front, 22 inches in the back. The suspension allows the car to dramatically lower itself to just 27 mm from the ground for show display, giving it a true low-rider stance. Massive ventilated disc brakes with 6-piston calipers up front and 4-piston calipers at the rear ensure it can stop as well as it goes.

Inside, the Efijy blends retro styling with high-tech features. The minimalist dashboard is highlighted by a single color tachometer with a digital display, while a multimedia screen slides out from the center console like an old-school TV. Gear selection is done through four buttons rather than a traditional gearstick, adding to its futuristic charm.

Though it never went into production, the Holden Efijy became a celebrated symbol of Australian car culture. It won U.S. Concept Car of the Year in 2007 and has appeared in several exhibitions, including the Holden Heroes display at the National Motor Museum in Birdwood, South Australia.

The Efijy wasn’t built to meet fuel economy standards or production goals—it was created for the love of cars. A rolling piece of automotive art, it celebrates a time when cars were bold, expressive, and designed with passion.
