# Porsche 917K No. 29 Siffert Ahrens Winner 1000km Zeltweg 1969 Werk83 1:12

> A 1:12 scale model car in die-cast metal by Werk83, reproducing the white-and-green Porsche 917K that gave the 917 programme its maiden race victory at the Österreichring on 10 August 1969.

The Porsche 917K 'Kurzheck' was built to exploit the FIA Group 5 regulations that opened the door to 5-litre engines from 1969. Porsche homologated 25 cars to qualify, and chassis 917-009 became the first of the breed to cross a finish line in first place. Running as number 29 under the privateer entry of Karl Freiherr von Wendt, it carries a livery that most collectors have never seen reproduced at this scale.

## The Porsche 917K and Its Flat-12 Engine

The 917K's defining feature was a shortened 'Kurzheck' tail that traded the aerodynamic drag of the long-tail 917L for usable mechanical stability. Power came from an air-cooled flat-12 displacing 4.9 litres, figures varying by source and state of tune. The homologation batch of 25 cars — built specifically to satisfy FIA scrutineers — set the stage for one of the most dominant runs in prototype racing history.

## 10 August 1969: The 917's First Victory

The 1000 km of Zeltweg, held at the Österreichring on 10 August 1969, was a round of the International Championship of Makes. Swiss driver Jo Siffert — a Porsche contracted driver and key figure in the 917 development programme — co-drove chassis 917-009 with German driver Kurt Ahrens Jr. Their car wore a white base livery with distinctive green front wings, the personal colour scheme of entrant Karl Freiherr von Wendt. The result, a first-place finish, marked the first outright victory in the Porsche 917's racing career, a moment that preceded Le Mans glory by less than twelve months.

## Werk83's 1:12 Scale Model of the Zeltweg Winner

Werk83 renders chassis 917-009 in die-cast metal at 1:12 — a scale that allows surface and livery detail impossible at 1:18 or 1:43. The white-and-green von Wendt livery, far less frequently reproduced than the Gulf or Martini factory schemes, is captured here as number 29 exactly as it appeared at the Österreichring.
