Park in Canada but Lauda decided to depart early because he felt Ferrari could not run 3 cars at a race without its resources being stretched. Then at the last race at the Mount Fuji circuit in Japan, Villeneuve had an enormous accident where he was launched over Ronnie Peterson's 6-wheel Tyrrell at the end of the straight, cleared the Armco barrier and landed in a spectator-restricted area. 2 spectators who were standing in this restricted area were crushed and killed instantly by the airborne Ferrari. The 312T2B was used for the first two races of 1978, before being replaced by the 312T3. 312T3 The 312T3 was introduced for Villeneuve and Reutemann at the third race of the 1978 season. The car featured the same flat 12 engine as had been used since 1970, albeit tuned to give around 515 bhp. The chassis was completely new, with a new monocoque structure and a different suspension arrangement, designed to work with the Michelin tyres. The bodywork visibly very different, with a flatter top to the body, allowing improved air flow to the rear wing. All the hard work came to nothing though as the pioneering Lotus 79 ground effect "wing car" took on and beat all comers with ease that season, and Ferrari were left to pick up the pieces of any Lotus failures. Reutemann won 4 races, whilst Villeneuve won for the first time at the final race, his home race in Canada, but it was more a season of consolidation. Reutemann moved to Lotus for 1979, replaced by Jody Scheckter. Ferrari was 2nd in the Constructors' Championship. 312T4 In 1979, a significant amount of progress was made in aerodynamics and to challenge Lotus, Forghieri realised he had to follow their lead and design a ground effect car for 1979. The 312T4, introduced at the 1979 South African Grand Prix was closely based on the 312T3. Its origins placed restrictions on the aerodynamic design since the T series had never been designed with ground effect in mind. The 312T4 monocoque was designed to be as narrow as possible, to take advantage of ground effects, but this was limited by the width of the flat 12 engine, which partially sat in the area where the upswept underside should have been, therefore the 312T4 was more of a wing car similar to the Lotus 78. The car was extremely reliable, recording only
