A4 paper, pencil, about 8 - 9 hours of work.
The road variants of the 205 T16 shared the transverse mid-engine, four-wheel drive layout of the rally car, but had much less power, at around 200 PS (147 kW; 197 hp).
The T was for Turbo; the 16 stands for 16 valves, an uncommon feature at that time for turbocharged engines. Outwardly similar to a normal 205, the T16 had wider wheel arches, and the whole rear section lifted up to give access to the engine.
Underneath, the complex drivetrain from the rally car was kept to abide by the Group B rules. All 200 built were left-hand drive.
True icon of the Group B, one of my favourite cars at that time, still love that car very much.
