The 49 was a testbed for several new pieces of racecar technology and presentation. Lotus was the first team to use aerofoil wings, which were introduced at the 1968 Monaco Grand Prix. Originally these wings were bolted directly to the suspension and were supported by slender struts. The wings were mounted several feet above the chassis of the car for effective use in clean air, however after several breakages which led to dangerous accidents, the high wings were banned and Lotus was forced to mount the wings directly to the bodywork.
