Подвеска

Новый Форд Фокус 3 RS обзавелся умной системой полного привода Ford Performance AWD, которая, посредством управляющей электроники и многодисковых муфт, способна распределять нагрузку как между осями, так и между отдельными колесами. Отсюда и наилучшая управляемость среди хэтчбеков. А роль заднего дифференциала выполняет угловой редуктор. Кроме того, установлены новые поперечные стабилизаторы, укорочены рулевые тяги, заменены амортизаторы и установлены жесткие пружины.

Автомобиль оснастили функцией Launch Control (система быстрого старта) с четырьмя режимами работы: Normal, Sport, Track и Drift. Предполагаемая цена нового Форд Фокус РС 40000$.

Самый спортивный Форд Фокус рс от Форд наглядно показывает свои возможности в шикарной презентации (как это принято в компании Форд), смотрим видео:

Production

A blue production RS200.

FIA homologation rules for Group B required the construction of at least 200 road-legal vehicles, and Ford constructed these 200 units with spare parts for another 20+ units put aside for the racing teams. Those chassis and spare parts were later also used to build a couple of non-genuine, so-called bitsa cars.

A total of 24 of the 200 original cars were reportedly later converted to the so-called «Evolution» models, mostly marked by their owners as «E» or «E2» types. Ford’s first intention was to mark the FIA-required 20 «Evo» cars as series numbers 201 to 220 but as this was actually not necessary according to the FIA rules they later kept their original series numbers (e.g. 201 = 012, 202 = 146, 203 = 174 et cetera).

The original bodywork tooling for the Ford RS200 was latterly bought by Banham Conversions, who used it to make a kit car version based on the Austin Maestro. Due to being a basic rebody of the Maestro, the Austin-Rover engine ancillaries are actually to be found at the front of the vehicle.
