Isuzu adds two models to its I-series pickup truck lineup for the 2007 model year. The i-370 4x2 Extended Cab and the i-370 4x2 Crew Cab double the fleet as they join the i-290 4x2 Extended Cab and the i-370 4x4 Crew Cab models. The changes mark the introduction of a new, 242-hp, 3.7-liter inline 5-cylinder engine into the extended cab architecture and make the larger Crew Cab cabin available with a 2-wheel-drive (2WD) powertrain.
