Colour
Tangerine orange

Porsche 911 Carrera RS 2.7 Lightweight (serial number 1177), one of roughly 200 M471 Sport variants, was specially ordered by Porsche for Finnish motorsport star Leo Kinnunen. Delivered via the Hahn dealer in Fellbach, it carries unique factory-specified modifications including wide ST-style wheel arches, a 1974-style flat rear spoiler, a Matter roll cage, and rally-oriented interior. Used to prepare for the 1973 1000 Lakes Rally and the Targa Florio, the car passed to several Finnish enthusiasts after Kinnunen's personal ownership and retains much of its original Tangerine paintwork, correct M471 interior, and an AAW Racing Team decal.

Maintenance & restoration

  1. 1973
    Modification

    Car was fitted at Kinnunen's request with enlarged ST-style wheel arches to accept wider wheels and tyres, a flat 'tea-tray' rear spoiler of the type used on the 1974 Carrera 3.0 RS (rather than the standard ducktail), a limited-slip differential, a Matter alloy roll cage, deep Recaro rally seats with adjustable backrests, Repa racing harnesses, rubber floor mats, an oversized steering wheel, and a raised passenger seat.

    These specifications were factory-applied at the point of original build/delivery via the Hahn franchise in Fellbach, Germany, to suit Kinnunen's rally and competition preparation requirements.
