The Golf chassis is named after the first model released for sale that used this chassis:
– VW Golf Racing Group 2, model number 58025 released to sale in 1981 and available on the market until 1984
– Renault 5 Turbo, model number 58026 released to sale in 1981 and available on the market until 1984
This model was developed by taking the best from previously released models:
– the standard chassis on both models is made of FRP: Fiber Reinforced Polymers, polymer matrix or fibre-reinforced materials. The chassis is a development of the Countach CS and F1 CS chassis. The chassis is shorter than a chassis of the F1 CS, but takes its shape by adopting the dimensions and proportions to those of a Countach CS chassis. Pictured on the left is the metal Countach CS chassis, in the centre the Golf chassis in FRP and on the right the F1 CS chassis in FRP.
– The servo – receiver – main battery plate is a development of the one installed on the Countach and Countach CS chassis. It changes the layout in such a way as to have the greatest weight concentrated in the centre, bringing it closer to the centre of gravity. Pictured on the left is the Countach CS – Countach chassis plate, in the centre the Golf chassis plate and on the right the F1 CS chassis plate. The main battery is located at the front for the Countach CS – Countach chassis, in the centre for the Golf chassis and at the rear for the F1 CS chassis.
– front bumper is common to many chassis (934, Countach, Countach CS)
– the steering save is that of the Brabham BT50 BMW Turbo model number 58031 and Super Champ model number 58034
– The drive is rear-wheel drive with a choice of differential or fixed gear. The rear axle with differential is common to many chassis (934, P34, Countach, Countach CS, Sidecar B2B, F1 and F1 CS),
– the 4 sponge wheels are those of the F1 CS chassis- On this model the front sponge wheels are the Diplo version.
– the rear system is specially developed for these two models and has several functions: installation of the RS540 motor, installation of the rear axle, houses the four service batteries, installation of the mechanical speed control system and allows the body to be locked to the chassis
– The bodies are made of Lexan and are complemented by styrene parts: the grille with front bumper (highlighted in the picture in red for the VW Golf and in orange for the Renault 5 Turbo), the air intakes on the bonnet (highlighted in the picture in purple for the VW Golf and in green for the Renault 5 Turbo) and the driver.
– is one of the few models where all joints are ball joints (highlighted in red in the picture)
The main differences between VW Golf Racing Group 2 and Renault 5 Turbo is the body of the two models, in the picture on the left the VW Golf and on the right the Renault 5 Turbo.
From 2011 to the present day (2023), the body of the Golf Racing Group 2 and the Renault 5 Turbo have been used in many re-releases using a different chassis:
– Tamiya Renault 5 Turbo Rally model number 84227 released in 2011 on the front-wheel drive M5-Ra chassis,
– Tamiya Volkswagen Golf Mk.1 Racing Gr2 model number 84316 released in 2013 on front-wheel drive M.05 chassis,
– Tamiya Volkswagen Golf Mk.1 Racing Gr2 model number 47308 released in 2016 on front-wheel drive M.05 chassis. The same numbering was also issued in 2017 and 2022,
– Tamiya Renault 5 Turbo Rally model number 47435 released in 2020 on front-wheel drive M05-Ra chassis
The chassis of the modern version has no parts in common with the original, the body of the original versions are respectively the same as the modern versions of the VW Golf code number 11828024 and Renault 5 Turbo code number 11825009. The modern versions of the VW Golf and Renault 5 Turbo retain the styrene parts developed for the original models in order to make the Lexan bodies more realistic: the grille with front bumper, the air intakes on the bonnet and the driver. The only difference between the original and modern models in the bodies is the different fixing system to the chassis, which changes from 3 pins to 4 pins, in the picture below the 4 holes of the modern bodies.
