There was a lot we enjoyed about the Sonoma 4x4. As expected, ride quality was a bit jouncy with the heavy duty suspension package. These trucks ride much better with a cord of wood in back. The suspension does its job well though when in its element--driving on rough terrain, carrying heavy loads or pulling a trailer. The V6 engine provided healthy throttle response across the power band, which made everyday driving enjoyable and assisted with passing maneuvers. Sonoma's two V6 engines were upgraded with sequential central port fuel injection and now offer the best available combination of power and torque in the compact pickup truck class. Our Sonoma 4x4 served up a robust 190 hp at 4400 rpm and 250 lbs.-ft. of torque at 2800 rpm.
The base 2.2-liter four-cylinder engine has an improved, yet simplified powertrain control module, which improves reliability and simplifies troubleshooting. An improved starter motor enhances reliability.
Our SLS was equipped with a four-speed automatic transmission with overdrive and electronic control, a $1,070 option. The transmission has been improved this year with a new hydraulic pump that delivers up to 20 percent more output. Aluminum valves help reduce leakage and improve internal oil flow and a new clutch-plate design increases efficiency.
Sonoma's electronic transfer case called Insta-Trac is a dream to operate. Simply push a button to shift into high- or low-range and you're ready for tough terrain. A high ground clearance, a locking differential, aggressive tires, gas-pressure shocks and heavy duty multi-leaf rear springs produced positive results during our off-road excursions. The Off Road Package is designed for the serious.
The brakes worked well, though the pedal felt soft at the top third of its travel, a trait common with GM trucks. The truck will stop, but the driver learns to use the brake pedal with authority. The four-wheel anti-lock brakes work well when engaged.
