Alto was built with left-hand-drive in South Korea, Poland, Romania and Uzbekistan as the Daewoo Tico, and also in China by Anchi. 660cc era When the Kei car standards were changed in 1990, the engine was upgraded to the (F6A), and the Alto became the CL/CM/CN/CP21 in the process. The new standards also allowed for a longer car, which meant new bigger front and rear bumper, and new headlights and grille. Lower grade Van versions received a 6-valve engine, while passenger car versions (and the l'Èpo Van) got a single-cam 12-valve version. This engine was upgraded to in January 1991. 4WD versions with the three-speed automatic transmission were fuel-injected and offered three more horsepower. The F6A-engined Works RS/X and RS/R still claimed the legally limited with of torque, but the lower grade i.e. Turbo (introduced in July) received a 6-valve SOHC-engine producing and of torque (slightly more than the high-revving, twin cam RS). Reflecting decreased tax benefits for commercial Kei cars, the Works series were now classified as passenger vehicles, allowing for a real back seat. The lineup was reorganised in January 1991, with a lot of new engine specifications. In September 1991, responding to increasing safety demands, the Alto received side impact protection. Also, the vertical door handles (see picture on the right) on three-door versions were replaced by traditional horizontal ones. The re-engineering was extensive enough to necessitate new model codes, with vans becoming CL/CM22 (FF/4WD) and passenger versions (including the Works) now called CR/CS22. While most of the engines remained as they were, the Alto Van's engines were updated with power output up to . This was the model that reached limited exports. The New Zealand version was mostly the same as the Japanese market five-door van model, with a cargo-oriented bare-bones trim combined with the rather soft Japanese suspension settings and light, low-geared steering. Unlike the Japanese models, however, this low spec was coupled to the (carbureted) 12-valve engine with and a standard five-speed transmission. A three-speed automatic was also available. In a period test, this model reached the 0–100 km/h benchmark in 15.9 seconds and a top speed of . A very limited production version for competition purposes arrived in 1992, called the Alto Works R. This was a lightened, strict two-seater with four-wheel-drive, a close-ratio five-speed transmission, and a tuned engine - although official output remained , as required by the Kei regulations. The
