The Daihatsu Terios is a mini SUV, first released in 1997 by the Japanese car manufacturer Daihatsu. The engines are a modified Daihatsu Charade 1.3-litre or kei car 660cc unit, with constant four wheel drive (4WD) or two wheel drive (2WD), respectively. It has a five-speed manual transmission or a four-speed automatic transmission. The width of the first generation Terios is less than 1500mm, to fulfil the kei car regulations. Also to meet these regulations, the kei car Terios is shorter, losing the rearmost side window. The second generation of Terios was co-developed by Daihatsu and fellow Japanese manufacturer (now parent company) Toyota.
