brilliant fuel economy

After travelling a little more than 4,000 kilometres, the average combined fuel economy clocked in at 9.3 L/100 km. The best highway economy was 8.2, though it was easy to consistently get 8.4. That, in a pickup, is spectacular. More importantly, the Ram Laramie month-long test left an indelible mark, the memory of which will be long enjoyed.

As noted throughout this test, the diesel’s acoustics are perfect. And, wow, is it quiet on the highway.

but the wisdom Chrysler displayed when it decided to make a 3.0-litre EcoDiesel available for the Ram 1500
