Overall, the Bonneville SSEi is in the Pontiac tradition, which interprets
"excitement" to mean a snazzy interior with lots of gadgets.
The interior comes with a choice of cloth or leather and the option of a front
bench or a pair of bucket seats. The optional power seat controls are either located
conveniently on the side of the seat or on the center console, depending on the type of package ordered.
Our Bonneville, a basic black SSEi, came with the top-of-the-line 12-way
adjustable leather bucket seats. The console-mounted seat controls with this system include nine buttons to adjust the front seats, with a mode switch for switching between driver and passenger adjustments. We thought this system makes the console look too much like a touch tone command center and wondered whether dust and debris would accumulate among the buttons over time. Don't spill the coffee around here. Three different buttons control the lumbar support, but none of the settings was particularly effective.
Five more buttons, arrayed like sentries along the console-mounted shifter, are
used to select among three driving modes. Two buttons control shock absorber
damping--one for the normal touring mode, the other for the firmer performance mode. Two buttons control shifting--one for normal driving, the other for maximum
acceleration performance. The remaining button is used to switch the traction control system on or off.
We couldn't decide whether we liked the optional head-up display that projects the
speed, turn signal indicators and warning lights, such as the low-fuel indicator, onto
the windshield. The intensity of the display can be adjusted using the dimmer switch or turned off, and this display does seem to be an improvement over similar systems we've seen in other cars.
Large analog speedometer and tachometer dials dominate the instrument display,
flanked by an attractive, highly legible assortment of traditional analog readouts
that include oil pressure, coolant temperature, battery voltage and fuel quantity.
Overall, it's an attractive layout.
Another "excitement" element is an optional electronic compass on the far left of
the instrument panel that looks like it could be a fly-to indicator for a jet fighter
coming in for a landing. This is balanced on the right with an electronic outline of
the car warning the driver of doors not fully closed, an open trunk or low fuel.
The optional electronic climate control system, meanwhile, provides a digital map
of the air temperature and velocity along with its source. Like many climate control
systems, it turns on the air conditioning compressor even when it's 20 degrees
outside.
The stereo system controls are easy to operate, whether adjusting the volume with
the relatively large knob or using the optional steering wheel controls.
An optional electronic load-leveling system detects when weight is added to the
rear seats or trunk and causes a compressor to pump air into the rear shocks to raise the rear of the car. This system comes with a thoughtful trunk accessory kit that includes a spotlight, first-aid kit, gloves, a windshield scraper and an air hose. The air hose can also be screwed onto an air valve in the trunk, allowing the compressor to be used to inflate a tire or that inflatable raft.
The Bonneville provides relatively rapid transport, so choosing between the two
3.8-liter V6 engines available comes down to whether you want to go fast or faster.
The base 205-horsepower 3800 Series II V6 is a solid powerplant that delivers
exceptional acceleration. There's no shortage of power for merging onto the freeway
and the generous torque provides quick, effortless acceleration. This engine is a
smooth companion around town and achieves 30 mpg on 87-octane fuel on the highway.
The supercharged 3800 Series II V6 adds even more power to this equation and the
truly power hungry will find it delightful. However, it also adds about a thousand
bucks to the purchase cost, drops fuel economy to 26 mpg on the highway and is a
little noisier than the standard V6.
The engine and smooth 4-speed automatic is one element that helps make the
Bonneville fun to drive. The other element is the suspension, which has been revised this year to reduce body roll in the corners and improve road feel. Pontiac's optional Computer Command Ride system adjusts shock absorber performance to how the car is being driven by measuring steering inputs and acceleration and braking rates.
A new speed-sensitive power steering system improves road feel, while making it
easier to park.
Freeway driving is clearly the Bonneville's forte, with handling best suited to
fast sweeping turns and working through brisk traffic. The big Bonneville is a little
less comfortable on tight twisting roads, but still superior to a good many other
vehicles in its class. The suspension is relatively firm, but does a good job of
soaking up potholes and smoothing ripply interstates and road irregularities.
