Use of variable valve timing results in a very smooth, flat
torque curve, where
85% of maximum torque is available from as low as 1500 rpm.
The engine structure is
two blocks of eight cylinders, set at 72 degrees to each other
and sharing a common crankshaft.
Each block has two rows of four staggered
cylinders set at an angle of 15 degrees to each other.
This engine structure provides a high cylinder capacity and performance
in an engine which is exceptionally stable and extremely compact.

The W16 is coupled to a five-speed transmission and the rear axle
differential is integrated as part of the engine oil sump.
