Electric cars with cutting-edge green technology and vehicles remote-controlled by smartphones catch the eye at the first Tokyo Motor Show held since Japan’s devastating earthquake. Companies showcased concept cars with “transformable” bodies and automotive computers linked to smart phones, while showing off energy-efficient vehicles with electric, fuel cell and hybrid engines. Compact, fuel-efficient cars are also on display, with Japanese carmakers hoping they can galvanise moribund domestic sales as the sector tries to pick itself up from March’s quake-tsunami and the ongoing global economic downturn.
