In 1969, Miles had to develop the Lotus 63 4WD car while World Champion Graham Hill and Jochen Rindt refused to drive this design, considering it a death trap. In five GPs, Miles finished only once, in 10th place. In between, the car was given twice to Mario Andretti, but he did not finish either. Miles did qualify mid-grid for the Canadian GP at Mosport, where the difficult combination of fast sweeping bends suited the 4-wheel-drive Lotus 63, which was a 'disaster' on twisty tracks.
