Diesel Engines Competitive in the Long-Term Future

Diesel Engines Competitive in the Long-Term Future

Diesel engines will continue to be viable for the foreseeable future for several reasons.

First and foremost, diesel models will continue to account for the overwhelming majority of global medium and heavy motor vehicle engines because they offer greater torque, and are more durable and fuel-efficient than comparable gasoline engines.  Diesel engines also have a longer lifespan, lower maintenance requirements, and higher residual value.

Second, diesel engine fuel is less expensive than gasoline in numerous countries, helping make diesel light vehicles popular in these areas.

Third, while electric and hybrid vehicles are expected to capture market share from diesel models in mature markets with demanding emissions regulations, this will only have a limited impact on demand at the global level.  The infrastructure required for widespread electric vehicle is still lacking in most countries and will take years to develop.  Advanced diesel models can also get better mileage than some gasoline-electric hybrid vehicles.

Finally, the automotive diesel engine industry has a long-tradition of technological innovation.  Since 1990, the design of diesel engines has improved considerably, and a wide range of performance-improving and emission-cutting technologies have been introduced.  Portraying diesel engines as a technology of the past ignores this record of innovation.
