The Volvo 7000, later Volvo 7700, was an integrally-constructed fully low-floor single-decker rigid bus and single-decker articulated bus built by Volvo between 1999 and 2012. It was generally available as 12-metre and 18-metre on both diesel and CNG, and from 2010 as a 12-metre hybrid electric. A trolleybus version has also been built. History The model was developed in Finland under the name Carrus K206, but when presented in late 1998 together with the Säffle-built Volvo 5000 it became known as the Volvo 7000. In addition to the 12.0 metre being built on B7L, it was also available as the 18.0 metre articulated Volvo 7000A built on B7LA. CNG versions were built on B10L/B10LA. Standard 12- and 18-metre versions were manufactured at the plant in Wrocław, Poland. In Vantaa, Finland (Carrus Oy Wiima) the 12-metre version was built, in addition to some customized lengths. Turku received some short 11-metre ones, while Helsinki received some longer ones at 12.89 metres. Production in Vantaa ceased when the plant was closed down in 2001. By this time only 43 7000s had been delivered to customers in Finland, in addition to a handful of demonstrators for various countries. During 2003 the model was renamed to Volvo 7700 and Volvo 7700A, to better fit with the other model names introduced since 2001, like the 8700 and the 9700. No other changes than the name is known to have been done to the model that year. In 2006 it was upgraded with the B9L and B9LA chassis, and at the same time got a facelift. The front was changed with a "grille" and new headlights, and the rear end got a "lump" at the top and new taillights. The rest of the exterior was more or less unchanged. In 2008 the first prototypes for a hybrid electric bus named Volvo 7700 Hybrid were built on the B5LH chassis. Serial production started in 2010. Volvo's Hungarian subsidiary Alfa Busz Kft in Székesfehérvár manufactured a batch of 102 Alfa Cívis 12 in 2009, which were made to look similar to the 7700. There were two prototypes and then 100 buses for public operator DKV in Debrecen. In addition a batch of 40 Volvo 7700A were delivered to DKV the same year, being specially adapted, they were rebranded as Alfa Cívis 18. The Volvo 7700's successor, the Volvo 7900, was introduced in 2011, and the last 7700s were built
