History of the Holden Efijy
A tribute to the FJ
The design of the Efijy pays tribute to the 1953 Holden FJ, the second Holden model. The concept was designed and built entirely in house at GM Holden’s Australian design studio and engineering department, and the project was overseen by Holden chief designer Richard Ferlazzo. It is painted in a colour called Soprano Purple and has brightwork handmade from billet aluminium.
Under the body
The Efijy is based on a lengthened Chevrolet Corvette floor pan and uses a 6.0-litre LS2 V8 with a Roots supercharger, producing 480 kW (644 hp) at 6,400 rpm and 560 lb-ft of torque at 4,200 rpm. Power goes to the rear wheels through a rear-mounted four-speed 4L60E automatic transmission with a limited-slip differential. The exhaust is a fully custom stainless steel unit with billet aluminium tips.
The car rides on an air suspension system that lowers it when stopped, and it has electronic instrumentation including a multi-use display screen that disappears into the dashboard.
After the show
Since its debut at the Australian International Motor Show in 2005 the Efijy has been named the United States concept car of the year for 2007. Once back in Australia it visited the National Motor Museum at Birdwood, South Australia, in February 2008 and again from December 2020 as part of the Holden Heroes exhibition alongside 12 other significant Holden production and concept vehicles. In 2025 it appeared at the State Library of South Australia in the Rear Vision: Holden Collection exhibition.
