HDT
VK Commodore SS Group A ('Blue Meanie')

Why it matters

The VK Commodore SS Group A was the homologation special built by Holden and Peter Brock's HDT so the Commodore could race under the Group A rules CAMS adopted in 1985. Around 500 were made (some sources say 502), all in Formula Blue, giving the car its 'Blue Meanie' nickname.

How rare is it?

Six separate kinds of rarity – never combined into one number.

Each kind of rarity is rated separately and never combined.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

When Australian touring-car racing switched from Group C to Group A in 1985, Holden and HDT built a road series to homologate the VK Commodore SS. The engine was a de-stroked 4.9-litre version of Holden's 5.0 V8, tuned by HDT, with an M21 four-speed manual and model-specific aerodynamic parts. Build number 005 was Peter Brock's personal car and sold for more than $1 million in 2021.

Identification guide

How to tell an original from a replica or later conversion.

Genuine cars were all painted Formula Blue and carry a numbered build plate on the glovebox lid (e.g. 'Build No. 005/500'). Other features are a pale blue interior with Scheel front seats, Momo wheel and HDT shift knob, a specific front air dam, grille insert and rear spoiler, 16-inch 'Aero' alloy wheels and Bilstein suspension.
