The 1968 Formula One season included the 19th FIA Formula One World Championship season, which commenced on 1 January 1968, and ended on 3 November after twelve races.
Although they had failed to win the title in 1967, by the end of the season the Lotus 49 and the DFV engine were mature enough to make the Lotus team dominant again. For 1968 Lotus lost its exclusive right to use the DFV. McLaren built a new DFV-powered car and a new force appeared on the scene when Ken Tyrrell entered his own team using a Cosworth-powered car built by French aeronautics company Matra and driven by ex-BRM driver Jackie Stewart.
Unsurprisingly the season-opening 1968 South African Grand Prix confirmed Lotus' superiority, with Jim Clark and Graham Hill finishing 1–2. It would be Clark's last win. On 7 April 1968 Clark, one of the most successful and popular drivers of all time, was killed at Hockenheim in a non-championship Formula Two event. The Scotsman had gone off the track caused by what was believed to be a deflating rear tire; 90% of the Hockenheim circuit was made up of 2 long, slightly curving straights running through thick forests. And because there was no protection from the solid trees lining the circuit on both sides, Clark's Lotus smashed into a wall of trees, breaking the hapless Scotsman's neck and killing him instantly; the car was totally destroyed and people had stolen the dismounted engine and gearbox from the destroyed Lotus.
The season saw two significant innovations. The first was the arrival of unrestricted sponsorship, which the FIA decided to permit that year after the withdrawal of support from automobile related firms like BP, Shell and Firestone. In May the Lotus Formula One team appeared at Jarama in the Red, Gold and White colors of Imperial Tobacco's Gold Leaf brand. The second innovation was the introduction of wings as seen previously on various cars including the Chaparral 2F sports car. Colin Chapman introduced modest front wings and a spoiler on Graham Hill's Lotus 49B at Monaco. Brabham and Ferrari went one better at the Belgian Grand Prix with full width wings mounted on struts high above the driver. Lotus replied with a full width wing directly connected to the rear suspension that required a redesign of suspension wishbones and transmission shafts. Matra then produced a high mounted front wing connected to the front suspension. This last innovation was mostly used during practice as it required a lot of effort from the driver. By the end of the season most teams were using sophisticated wings.
