Turbo nanomotors : A dramatic increase of the speed of fuel‐driven nanowire motors is obtained using an Ag/Au alloy segment. These nanomotors offer speeds as high as 150 μm s −1 (75 body lengths per second), approaching those of the most efficient biomotors. The increase in the fuel decomposition rate associated with the electrochemical reactivity of Ag/Au alloys will enable the design of energy‐efficient nanomotors.
