Test Drive

Jack Roberts | April 01, 2012

As we moved off the highway onto two-lane back roads, my confidence remained high. The combination of engine power and tight steering held into the hill country as sharp curves and steep grades appeared out of the mist. The CT660 gobbled up everything the road had to offer without a hiccup. Very few drivers behind us seemed to feel the need to pass, even on this hilly, two-lane highway.

Based on my time behind the wheel of the CT660, you can expect Caterpillar to make its mark on trucking in a new way.
