General Motors’ Vauxhall subsidiary says it is ahead of schedule with a plan to source an extra €200 million ($273 million) in parts from U.K. contractors by the end of 2011.

Vauxhall says the new supply contracts ensure an additional €40 million ($55 million) a year is spent with U.K. suppliers and correspond to an overall increase of 15% in the auto maker’s domestic sourcing.

Parts now resourced from the U.K. range from carpets to powertrain components, cargo nets, suspension springs, load-compartment covers and exhaust systems.

GM-U.K. Chairman Bill Parfitt, also the first chairman of the U.K. Automotive Council’s supply group, says Vauxhall has succeeded in sourcing some of the parts previously brought in from countries such as Spain and Germany.

“It is part of Vauxhall’s plan to buy British and support U.K. manufacturing, and we are going to persevere in this direction,” Parfitt says in a statement.

Vauxhall’s Astra plant in Ellesmere Port and its Vivaro van plant in Luton have hired 268 additional workers in support of record line speeds to meet high demand and growing export levels.

Ellesmere Port is building the Astra Sports Tourer for all of Europe and such countries as Chile, South Africa and Israel. Some 92% of Sports Tourers built are bound for export.

In the year’s first eight months of the year, 83,338 Sports Tourers were produced, with the plant running two shifts in general assembly and three shifts in the press, paint and body shops.

Luton’s van plant, recently named to build the next-generation Vivaro in 2014, is operating two shifts producing several variants of the current model. About 65% of production is shipped to mainland Europe.
