Pontiac likes to point out that the Bonneville has been
satisfying customers since the 1950s. It is quite a claim,
but if you've been around for that long, you know you're
doing something right. The big sedan has certainly seen
its share of ups and downs, and has come through it all
For 2004, there are a few new interior refinements in the
Bonneville. However, the real news is the introduction of
the top-line GXP model. It uses V8 power to live up to the
Pontiac driving excitement billing, and it has a decidedly
refined interior setting.
The 2004 Pontiac Bonneville is offered in three model trims:
SE, SLE and GXP.
The four-door 2004 Pontiac Bonneville is the largest sedan
offered by Pontiac. It can seat six passengers when fully
loaded, and provides 18 cubic feet of cargo volume. Up front,
the maximum legroom is a cavernous 42.6 inches.
A CD player and Monsoon eight-speaker sound system is just
one of the many standard features found in the new GXP model.
Others include leather upholstery, memory seats and dual-zone
climate control. In addition, the shifter handle is brushed
aluminum, a carbon-fiber trim is abundant and the interior
switches are a rich ebony.

The performance-tuned GXP model doesn't hide itself on the
road; it proudly displays what it has. Dual exhausts let
out a noticeable rumble when the engine fires, while 18-inch
V-rated performance tires on styled aluminum wheels add
superior grip at the corners.
The GXP further distinguishes itself with a refined styling
that includes new fascias, headlamps, taillamps and a spoiler.
SE and SLE models are fitted with a 3.8-liter V6 engine
with 205 horsepower at 5200 rpm and 230 lb-ft of torque
at 4000 rpm. The 2004 Pontiac Bonneville's 4-speed automatic
transmission shifts quietly and quickly, without jarring
Under the hood of the new GXP is a 4.6-liter Northstar
V8 engine with 275 horsepower at 5600 rpm and 300 lb-ft
of torque at 4000 rpm.
GXP's performance-tuned handling package includes a four-wheel
independent suspension, the StabiliTrak electronic stability
system and an electronically controlled transaxle with a
3.71 final drive gear.
Safety and Security
The well-equipped 2004 Pontiac Bonneville addresses safety

a tire-pressure monitor and daytime running lights.
