We need more 2-cylinder engines in the world

It's somewhat odd the lack of 2-cylinder engine developments for compact vehicles, as those could become a table of salvation for the Diesel combustion process in the European market. Fewer friction and pumping losses, and eventually some parts interchangeability with 4-cylinder engines in the 1.6 to 2.0-litre range still likely to remain widely available for light-duty commercial vehicles in the foreseeable future, might justify such approach as much as the well-documented modularity of ancient engines not only for stationary, agricultural and marine applications but also for car engines. The ever-growing power and torque per litre in newer generations of engines, and the popularity of turbocharged 1.0L petrol engines with 3 cylinders, may justify a 2-cyl turbodiesel as a more utilitarian approach closer to the roots of the early popularity growth of Diesel engines.
