Porsche has committed to the Intercontinental GT Challenge with a ramped up effort that includes a dedicated lineup of factory drivers, the German manufacturer has confirmed.

Dirk Werner, Romain Dumas and Fred Makowiecki have been assigned to contest the four-round championship as a trio, in pursuit of the drivers’ title.

They will share the wheel of a Porsche 911 GT3 R entered by locally based teams in the Liqui Moly Bathurst 12 Hour, Total 24 Hours of Spa, Suzuka 10 Hours and California 8 Hours at Mazda Raceway Laguna Seca next year.

All three drivers will also contest the Blancpain GT Series Endurance Cup season in a Manthey-entered Porsche, with the Spa event doubling as a round in both series.

No word has been given on the teams that will enter the Pro class Porsche for Bathurst, Suzuka and Laguna Seca, although Porsche had utilized Walkinshaw Racing and Wright Motorsports for the Australia and U.S. rounds this year.

Additional Porsche entries are expected for all four races, with Competition Motorsports and Black Swan Racing already committing to Pro-Am class entries for Bathurst.

October’s 2017 season-ending California 8 Hour, meanwhile, featured entries from Wright, Black Swan, GMG Racing and Calvert Dynamics.
