Lotus 34 at the Indianapolis Motor Speedway Museum in 2022.

The Type 34 was Lotus' second Champ Car. Based on the earlier Lotus 29, it was a very similar car which 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.

At Indianapolis, Jim Clark qualified on the pole, joined by five other similar cars.[2] The Dunlop tyres failed during the race, leading to Clark crashing and the second 34 being parked.[3]
