The center has new engine test stands and capacity to build special-edition series of Smart cars in batches of 500 to 1,000 vehicles.
The number of employees will rise from 35 to 120 at the facility. The facility is a joint venture between the Micro Compact Car (MCC) unit of DaimlerChrysler and German tuner specialist Brabus.
"In the future there will be a top-line Brabus version of each of the Smart series," said company boss Bodo Buschmann at the launch of the new Brabus versions of the Smart City Coupe and Convertible.
The new two-seaters are fitted with modified engines and transmissions -- due to smaller fitting dimensions for the exhaust the engines only have 75hp instead of 82hp -- and are currently manufactured in the Smart plant in Hambach, France.
All exterior and interior components, exhaust systems and small components are supplied by Brabus. Production start-up was in February and production has risen to 80 Brabus models per week.
At the beginning of 2004 a roadster with 110hp will be launched. A more powerful version of the future Smart four-seat "Forfour" is also planned for next year.
