Learn the facts: Modern diesel vehicles

What is the issue?

Modern diesel vehicles have become a compelling choice for drivers who care about performance, cost and the environment.

What do I need to know?

  • Diesel engines are more efficient and reduce fuel consumption. 
    The diesel compression ignition engine is more efficient than its gasoline spark ignition counterpart. This aspect and the higher energy content of diesel fuel (10% on average) reduce fuel consumption 15 to 30%.
  • Diesel vehicles can save you money. 
    A diesel vehicle costs more than the same model equipped with a gasoline engine. However, the lower fuel cost helps offset the higher purchase price. The payback period depends on how much you drive and the relative price of diesel and gasoline.
  • Diesel vehicles provide improved performance. 
    Today’s diesel vehicles are cleaner, quieter and perform on par or better than their gasoline counterparts. The improvements result from the availability of cleaner fuels and the use of advanced technologies, including electronic controls, common rail fuel injection, turbocharging, sound dampening and exhaust emission reduction components.
  • Diesel vehicles are a smart choice for the environment. 
    A diesel vehicle offers better fuel efficiency and lower carbon dioxide (CO2) emissions than the same model equipped with a gasoline engine. Today’s diesel engines produce substantially fewer emissions than earlier models and are required to meet the same emissions standards as gasoline vehicles.
  • Low sulphur diesel is readily available. 
    The sulphur content of diesel fuel sold in Canada has been reduced through increasingly stringent regulations, and since 2006 has been 15 parts per million. This ultra-low sulphur diesel fuel can be used in all diesel vehicles.
  • Diesel vehicle choices are growing. 
    In the past, diesel vehicle choices have been limited compared to their gasoline counterparts. However, automakers have begun to offer a greater selection to Canadian consumers.

How can I help?

  • Consider a diesel vehicle if you want to:
    • improve the fuel efficiency of your vehicle and save on fuel costs
    • lower your vehicle’s CO2 emissions
  • Be a knowledgeable buyer! 
    When you purchase a vehicle, ask about diesel vehicle options. Request a cost, environmental and performance comparison and decide whether a diesel vehicle makes sense for you.

What are the savings and benefits?

Diesel vehicles offer the greatest benefits over a longer period of time. The higher purchase price of a diesel can be recouped through lower fuel costs. The diesel option can offer fuel savings of 15 to 30% and CO2 reductions of up to 20% compared to gasoline vehicles. Actual savings depend on the specific vehicle and its operating conditions.
