After a stellar breakout performance in Can Am in 1966, Eric Broadley modified the Lola T70 into a coupe for endurance racing in 1967. Tony Southgate designed the bodywork, which featured a long tail for Le Mans. The plan was to defeat the Ford GT40, a car that was based on the Lola T6 from 1963. Broadley had initially agreed to help Ford with the project, but disagreed with management and left almost immediately.

The first taker of the Mk. 3 was, interestingly, Aston Martin, who had just scrapped their Le Mans program that year. Aston Martin provided a V8 engine which was both underpowered, giving up 15 mph to the GT40 and Ferrari 330 P4, and fragile, only lasting 25 laps before disintegrating.

For 1968, a few privateers used more powerful Chevrolet 5 liter engines, which saw success in shorter races, but longer endurance races were nearly impossible to complete due to fuel regulations. The lower octane used at Le Mans for example, burned up American engines.

While still focused on Can Am, a few modifications were made to the Mk. 3 based on Lolas experience with the T160. The new T70 Mk. 3b used a fully aluminum monocoque and fiberglass body, fuel injection, and a new Hewland 5 speed gearbox. This version was sold to Roger Penske and driven by Mark Donohue and Chuck Parsons for the Daytona 24 Hours in 1969, finally giving Lola a win over the Ford GT 40.
