Trucks play an important role in carrying freight and vocational applications like construction, mining, food service, landscaping etc. The engines powering these heavy vehicles are predominantly Diesel and CNG in 98% of all applications.


North America relies on trucks for moving more than 2 thirds of its freight.More than 92% of fleet operators in North America are small i.e. own less than 6 tractors. The fleet operators with more than 500 trucks have close to 45% share of new registrations, but they only represent about 24% of trucks in operation. The bigger fleet operators who own thousands of tractors differentiate themselves from smaller operators at multiple levels.

Light trucks or Light commercial vehicles are used in last mile delivery as well as intra-city applications and they account for more than 60% commercial vehicles sold globally.


Diesel powertrain has long dominated the trucking industry as the most preferred propulsion choice. However, with the evolution of lithium ion battery, mostly driven by development of electric car market, electric light trucks seem like the obvious next thing.


Engine downsizing and down speeding, both are not a new concept in the automotive industry. The internal combustion engine generates a lot of friction and consumes more fuel at a higher engine RPM (revolution per minute), therefore it is only natural to reduce the size of the engine and produce more torque at lower RPM.

Down speeding is very useful in long haul applications where the trucks would be running at a higher speed consistently and a lower engine RPM would reduce NVH(Noise, vibration and harshness )along with fuel consumption. Downsizing is not that effective in regional hauling where the trucks would run at inconsistent speed for shorter duration,including rapid acceleration and deceleration.

The long haul class 8 trucks typically cruise at around ~1100 RPM at 65 mph but the future targets for the same speed are in the range of ~900 RPM. The engine downsizing on the other hand will be useful in every possible application if the downsized engine is making as much power and torques as it was making earlier, only with less fuel required now.

Volvo has been focussing on turbo compounding on its engines to deliver 5%-6% more power and equally higher fuel economy as compared to similar displacement engines.

There are close to 40 Class 8 Truck models available in the North American market. To know more about Class 8 truck market in North America, read our report.

Cummins ISX 15 is the most sought-after Cummins heavy duty engine in North America.Paccar has been the single largest customer of Cummins for heavy duty engines for many decades. In past 2-3 years, Paccar has been promoting and updating its own MX-11 and MX-13 engines. In 2017-18, the uptake of its MX series engines was upwards of 45%.

The 1 ton power plants under the hood of Class 8 trucks are consistently shrinking in size and they will continue to do so in the foreseeable future as well.


China is world`s biggest truck engine market by volume, at 3 Million units per annum. North America is the second biggest market in terms of volume and value. 


The global truck engine market size is estimated at 6 Million units per annum, growing at 5.3% CAGR.
