on long journeys. From launch, the D Series was available with the ZF S5-42 five-speed gear-box and the six-speed cable-shift ZF S6-850 was launched as a compatible gearbox with the 170 hp Cummins. The D75 (7.5 t gvw) proved particularly popular in the UK and Ireland. Ashok Leyland ownership By 2004 continued losses at the factory meant a take-over was inevitable for its survival. A Czech-based investment company Odien started negotiations to buy the Daewoo Steyr B.V. 50.2% share holding—a process completed in early 2005. Odien carried out a complete physical and financial restructuring of the company which saw the truck business unit reduced from 120 buildings on an site to only four buildings on . As part of the restructuring, production of the Daewoo Avia D432-100 engine was halted. Under Odien's ownership the Avia brand was reintroduced with a new logo, and development of the Euro IV compliant models and a new 12 t gvm model, the D120, were begun. After discussions with several overseas manufacturers, Odien sold the truck business unit to Ashok Leyland of India in October 2006. Avia began a new era after the acquisition . A new company "Avia Ashok Leyland Motors SRO (AALM)" was formed. Sales in 2006 reached 650 units. Sales demand remained strong in the home market and in the UK, Spain, Hungary and Ireland. In 2006 in Ireland, Avia had a 16% market share of its segment. In 2006 the new 160 and 185 hp Cummins powered Euro IV models and the D120 were launched, the latter with gcw (gross combination weight) of up to 22000 kg for drawbar operation. In 2007 collaboration with the Tanfield Group of the UK saw the introduction of an "electric Avia", with AALM providing chassis cabs less engines, gearboxes and other diesel truck components to Tanfield subsidiary Smith Electric Vehicles for the Smith Newton all-electric truck. This was a successful collaboration with the shipment of engineless trucks forming a large proportion of Avia's sales. Hundreds of Smith Electric trucks with chassis and cabs from Prague are now in use in the USA. Euro V launch in 2009 saw a further increase in power outputs, with 185 and 207 hp variants of the four-cylinder Cummins ISBe Euro V available. The weight range continued to span from 6 to 12 tonnes gvw. 2010 and 2011 were period of success for the brand both domestically and in foreign
