Lotus 34 at the Indianapolis Motor Speedway Museum in 2022.

The Lotus 34 is an open-wheel race car built by Team Lotus for the 1964 Indianapolis 500. Driven by Jim Clark, who qualified on pole, and Dan Gurney, tyre failure led to Clark retiring and Gurney being withdrawn.

The Lotus 34 was a very similar car to the 29. It differed principally in featuring a four-cam 4195 cc (255ci) DOHC Ford V8 with Hilborn fuel injection, producing 425 bhp (317 kW), through a ZF 2DS20 gearbox.
