 A new cab-over-engine design was implemented, as were the wide profile super single tyres and central tyre inflation/deflation system.The naturally aspirated V12 engine T-930 was created by adding four additional cylinders to the existing T-928 75° V8 engine, used in the Tatra T138.The crankshaft consisted of six individual journals bolted together with front and rear pins all running on the main roller bearings and located on the axial friction thrust washers.
