After an inauspicious debut in 1967, the Lola T70 Mk 3 had gradually improved, and with sufficient production now completed to put it into the Sports category, it could run the far more reliable, race-proven, Chevrolet 5-litre V8 engine. The new Mk 3B, designed by Eric Broadley, was the first racing car to use the new ultralight, ultra-strong, carbon-fibre. A victory in the opening championship round at Daytona for Roger Penske's team boded well. Lola withdrew its entries after Paul Hawkins burned to death in an accident in May driving a Lola at the RAC Tourist Trophy. Without the works team, it was Scuderia Filipinetti who ran a car for Jo Bonnier/Masten Gregory.
