The Sonoma's interior is roomy, comfortable and functional. The long,
wide body along with a thinner door design translates to greater shoulder,
hip and head room. Seat options include high-back bucket seats for two
passengers or a standard bench seat or reclining 60/40 split bench for
three.
Extended Cab Sonomas with automatic transmissions and bucket seats now
have the shifter located at the center console. Seats, as well as door
panels and carpet, are a Scotchguard stain-resistant fabric.
Models vary with the number of comfort and convenience features. In
addition to the features noted as a part of the Marketing Option Package,
ours was equipped with dual lighted visor mirrors, cup holders, passenger
assist grip and full floor carpeting with mats. Solar Ray tinted glass
($72) protects folks and fabrics from sun exposure and reduces heat. Sunvisors
with extensions for additional glare protection are a thoughtful addition.
A glove box, door pockets, and space behind the seats provide spartan but
basic stowage needs. Options for our test model also included power windows,
door locks and dual outside mirrors ($535) and an upgraded remote keyless
entry system ($140).
The Sonoma offers good visibility and an open, airy feel. A sloping
hood, narrow A-pillar and unobstructed views to the rear make for clear
views in all directions.
Analog displays of all engine functions are easily visible to the driver
with switches that are bold and easy-to-operate for sound and climate controls.
Although there are a variety of modern safety features in the Sonoma series,
including GM's standard daytime running lamps, only a driver's-side airbag
is available. The C/K full-size trucks received them for '97 and they will
be standard equipment in the compact pickups next year.
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.
