Press Release) PONTIAC UNVEILS 2009 SOLSTICE COUPE:
Hardtop Extends Appeal of Classic Design
NEW YORK Drawing inspiration from classic sports cars, the 2009
Pontiac Solstice coupe was created for drivers who appreciate both
dramatic styling and balanced performance. Unveiled at the New York
Auto Show as a GXP model, the Solstice coupe builds on the success
of the convertible model while offering a greater range of
all-season driving opportunities.
For drivers still wanting an open-air experience, the coupe also
features a removable roof panel, fully opening the cockpit to all of
the sensations of the road.
Todays Solstice is the top-selling roadster in the U.S., and we
believe this new model has even broader appeal, said Jim Bunnell,
Buick-Pontiac-GMC general manager. The coupe has all the design
cues and pleasing performance of the original roadster, and is an
all-season alternative for people who enjoy open-air driving.
The coupe is expected to arrive in Pontiac dealerships in early
The making of a coupe
The new coupe was
inspired by the Solstice coupe concept shown at the North American
International Auto Show in 2002. True to the concept, it is a modern
sports car with classic lines. The roofline has a fastback shape
with stylized rails that run from the front of the roof to the
rear, culminating in a stylish and functional ducktail-style rear
The coupes roof is fixed aft of the B-pillars, with side windows
and a rear liftglass for access to the cargo area. The roof panel is
easily removed from the passenger compartment, and an optional soft
roof cover stores in the cargo area. A home storage case for the
roof panel will be offered through GM Accessories.
Engineering the design
Despite its dramatic new
look, engineers made only minor structural changes to create the
Solstice coupe. The rear fenders and rear fascia are the same as
those on the convertible. New taillight assemblies flow more
smoothly into the tapered roofline.
The Solstice coupe represents a major collaboration of design and
engineering, said Bruce Kosbab, chief engineer. The sleek lines of
the new roof give the car a fresh appearance, yet only minimal
changes were made to the body structure its a great example of
building on an already solid foundation.
The roofs structure was
strengthened with additional support elements, including an aluminum
roof bow attached with aluminum brackets. The bow and brackets are
stiff, yet low in mass, a design feature that pervades the coupes
overall construction. The roof includes a lightweight sheet molding
compound cover affixed to a rigid aluminum frame for additional
lightweight support. A lightweight magnesium roof panel frame weighs
just 31 pounds (14.2 kg) and can be removed by one person. The cover
is also made of sheet molding compound.
Powertrain and suspension
Because the change to a
coupe body style resulted in only a slight increase in curb weight,
no drivetrain or suspension changes were necessary to shift from the
convertible body structure. Initial tests have shown that the
Solstice coupe will deliver ride and handling, acceleration, braking
and fuel economy comparable to the convertible model.
The coupe is powered by a standard 2.4L Ecotec four-cylinder engine
that generates 173 horsepower (129 kW), while the GXP version is
equipped with a 2.0L turbocharged Ecotec engine with 260 horsepower
Much of the coupes
interior remains the same as that of the convertible. However, the
area behind the seats was redesigned for easy access to the cargo
area, and a storage tray was mounted directly behind the headrests.
Removing the folding-top mechanism made way for a new, flat cargo
floor and several storage compartments. The cargo areas covered
bins provide secure storage for smaller items. Cargo tie-down hooks
help secure irregularly shaped items.
