1:24 Sierra Cosworth 4x4 Engine Bay Super Detail Set

All-wheel drive for Group A

The Ford Sierra Sapphire RS Cosworth 4x4 came to the market in 1990 as an answer to what was happening in rallying: two-wheel drive was no longer enough on fast gravel stages. The turbocharged inline four YB with a head from the firm Cosworth gave around 220 horsepower in production form and its power was split between both axles through a viscous coupling. Factory crews ran the car in the world championship until the arrival of the Escort RS Cosworth.

What the set solves

The engine bay is among the most simplified places in injection-molded kits. The engine block tends to be cast as a rough shape without the valve gear, the cooling hoses are missing altogether and the fluid reservoirs are suggested at most by flat relief. The set fills this space with castings carrying fine detail, so that more than a gray surface can be shown under an open hood.

Why all-wheel drive in particular

The older two-wheel-drive versions of the Sierra could be unbeatable on a circuit, but on a loose surface they lost too much time to slides. The move to driving both axles was therefore a necessity, not a fashion, and it marked the whole layout under the hood: a transfer case and a propeller shaft were added, and with them the maze of pipework this set captures.

How the work goes

Expect small parts you will not manage without tweezers and a sharp scalpel. The proven method is to paint the individual groups separately, only then to seat them and finally to add the routing of cables from wire of a matching thickness.

When it makes sense

The effort pays off when the hood on the finished model is to be raised or removable. On a closed car all the work stays hidden and a set for the crew space will serve better.
