What does it mean to the customer?

To the customer better fuel economy means one thing: lower operating costs so they can make more money in profit.
Contact a Maxim Account Manager today to see if an International LT would be a good fit for your business.

As an example, if you had a 100 truck fleet and assumed:

• Each truck drove 120,000 miles per year
• Plug in your current average MPG per truck
»»7.69 MPG for Freightliner
»»7.71 MPG for LT with A26
• Diesel price $2.50/gallon

If each fleet drove a total of 12,000,000 miles per year, the results would be:

• The Freightliner fleet would buy 1,560,468 gallons of diesel per year
• The International fleet would buy only 1,556,420 gallons of diesel per year or 4,048 gallons less


• The Freightliner fleet would pay $10,120 more in fuel costs per year than the International fleet.

The A26 Fuel Economy Advantage

a26 engine 

1. The new cylinder head coolant passages are 50% less restrictive, reducing parasitic loss to the water pump, improving fuel economy.

2. The all new piston assembly features an increased compression ratio and a low friction skirt coating.  Fuel economy is further improved with low friction piston rings.

3. Oil cooler thermostat bypass allows oil to bypass the oil cooler in cold weather, to improve fuel economy.

4. A26 is specifically designed to use CK-4 and FA-4 oils.  FA-4 oil delivers optimal fuel economy.

2500 bar (36,300 psi) high pressure common rail fuel system delivers maximum fuel injection pressure to reduce emissions and fuel consumption, with multiple injection events for smooth and quiet operation.

The Test

PIT Group performed independent third party fuel economy testing over a 300+ mile route including flat and hilly terrain.
