Tamiya Opel Calibra V6 Cliff 1/10 4WD Electric Touring Car Kit. Nothing screams classic 1990’s touring car DTM racing like the Opel Calibras that tore up racing circuits across Germany. The Opel Calibra V6 Cliff took part in the 1995 running of the Deutsche Tourenwagen Meisterschaft (DTM) series. Entered by Joest Racing with the driver JJ. Lehto, the car was powered by a 2.5-liter V6 engine capable of 420 hp. Tamiya faithfully recreated this using a highly detailed polycarbonate body. This body sits on a TT-01 Type-E chassis for incredible performance.
