Peugeot 205 T16 won 2 World Rally Championships in 1985 and 1986, right before the Group B was ended because of it's dangerous nature.
Peugeot 205 T16, or Turbo 16 version was built as only 200 unit production run to comply with FIA requirements. It had increased wheelbase, middle-mounted 16-valve turbo engine and 4 wheel drive. It only had few details from original 205 model - the windscreen, doors and headlamps. Everything else was new - body, suspension, engine, drivetrain, interior.
