Itasca Navion Owner Tests The Four Cylinder Mercedes I-4 Turbodiesel Engine In A New Winnebago View

Don Cohen is the Blogger-in-Chief of Winnebago’s blog, GoLife. Two years ago, he and his wife Terry bought a new Itasca Navion and put 40,000 miles on it traveling throughout the United States. The Navion had the Mercedes V-6 engine.

Don knew that Mercedes had made a big change to its 2014 Sprinter – the introduction of a 161-hp, 266-lb-ft 2.1-liter I-4 turbodiesel engine. This new engine has four cylinders in an inline layout, compared to the older V-6 model which has two rows of three cylinders in a V setup.

The two test subjects: a 2013 Itasca Navion (6 cylinder) and a 2014 Winnebago View (four cylinder).

With the help of Winnebago and Transwest Truck Trailer RV (they loaned him the new motorhome), Don was able to test it through the Colorado Rockies, up and down 5% and 6% grades.

Watch Don Cohen test the new four cylinder Mercedes engine in a new Winnebago View.



It seems one of the most useful features of the new I-4 engine is that it has 7 gears compared to 5 in the V-6. Don was able to use engine breaking to maintain a smooth 60 mph during descents, taking the load off the brakes. Based on this test, which engine would you prefer if you had to choose between the two?
