Dennis's return to Formula One was well-timed. The recent poor performance of the former world championship-winning McLaren team had prompted Philip Morris executive John Hogan to initiate a takeover of the outfit by Dennis' Project Four. Effectively a reverse takeover, the team was rebranded as McLaren International with Dennis in control. In addition to hiring Barnard to begin work on the team's revolutionary new carbon fibre composite chassis, the MP4/1, Dennis also successfully recruited the Porsche automobile firm to build the cars' engines from 1984-87.
