The Daewoo Espero (also known as Daewoo Aranos in Spain) is a four-door, five-seater mid-sized saloon produced by the South Korean company Daewoo Motors from September 1990 to 1997. The Espero was the first car entirely developed by Daewoo, which until then had only manufactured models developed by Opel. With the body designed by Bertone, the model is based on the platform of the Daewoo LeMans, a badge engineered version of the Opel Ascona manufactured in South Korea. The engines were supplied by Holden, with options ranging from the GM Family 1 1.5L to the GM Family II 2.0L. The Espero was replaced by the Daewoo Nubira in 1997, but continued to be produced until 1999 in Eastern Europe. Development In the mid-1980s, Daewoo Motors was looking to enter in the mid-sized saloon market, which already had competitors like the Hyundai Sonata. To that end, it began developing a new model in 1986, codenamed "J-Car" (not to be confused with General Motors' J-Car, the company's worldwide car project from the 1980s). It then acquired from Bertone a body design previously discarded by Citröen, which would be used in the future successor of the Citröen BX. With access to General Motors technologies limited by contractual terms, Daewoo made extensive use of parts already being used on the Daewoo LeMans production. The steering, suspension, brakes and powertrain systems were the same as those used on the LeMans. The platform was also derived from the LeMans, but elongated behind the B-pillar to give the Espero longer wheelbase than the LeMans. The Espero debuted on the Korean market in August 1990. The Espero achieved very good results in the wind tunnel, at 0.29 Cd. Prototype There was also a prototype that looked very similar to the Espero. This prototype is called DEV 2 (DEV meaning Daewoo Electric Vehicle) and was presented in 1995 at the Korea Motor Show in Seoul together with the Daewoo Bucrane concept, Tico concept, Nexia, Arcadia and the NGV3 concept. It was basically a version of the Espero but made out of recyclable materials which did not impact the environment. The DEV 2 had a redesigned front. This prototype was shown only in South Korea and only once at these fairs. It was painted white pearl and had 'DEV' badges in blue at the rear doors, its interior was white and the rims where a three spoke design and white
