This long-running series has entered a new phase of its life as it turns its attention to electric vehicles. Filming required fast, smooth transitions between different technical setups within very limited time-frames. Often multicamera, multivehicle and up to four presenters, the filming days required tight teamwork and a large degree of technical flexibility. Car to car sequences required second and third contigency measures to ensure that there was never anything missed. High powered transmitters allowed the director to hear the on-board content from the tracking vehicle, and discrete 32-bit recorders captured sound within and around the feature vehicles.
