This two-liter unit is nothing more than an extension of the R18A. Increase the volume from 1.8 liters to 2.0 was due to the long-stroke crankshaft. Changes also affected the intake manifold, balancer shafts were installed on the motor. The cylinder head is left with one camshaft, sixteen valves and the iVTEC system. Motor without hydraulic lifters. From the previous version with the K20 index, the motor differs in a more urban character, improved traction at low and medium speeds. The engine has become more economical, reliable and simple.
