Powerful Diesel Engines

  |   diesel Engine photo This is an exciting time for people who want to drive diesel trucks. The engines under the hoods of 31/44- and 1-ton trucks are the most powerful and cleanest ever, and 11/42-ton trucks will soon get the benefits of the technology behind the Cummins, Duramax, and Power Stroke turbodiesel engines we've all come to love. Here are some of the engines that have been developed in the past decade that we'd like to see in a 11/42-ton pickup, SUV, or even a large car. Caterpillar/Ford 3.0L, V-6 HSDI
