Sometimes the little things mean the most. BMW has put three of these small radio-controlled MINIs to field duty at the Olympic Stadium: to ferry javelins, discuses, hammers and shots back from the field to the throwing area, saving time during competition and marshals having to run back and forth too.

The 25 kg, 10 hp cars are about a quarter scale of full size, and the sports equipment is simply placed in the car through the sunroof. Maximum capacity is 8 kg, with batteries holding out for 35 minutes of continuous usage before being fully recharged in 80 minutes.

BMW is London 2012’s Official Automotive Partner, and as such has a fully-electric vehicle fleet currently serving the Games which also comprises 160 1 Series ActiveE’s and 40 MINI E’s.

Imagine these little cars replacing ball boys and girls at Wimbledon.
