SATURN CURVE SUPERCHARGED COUPE HAS REFINED
FLAIR
DETROIT - Shape, color and sound affect the
senses. With the Saturn Curve concept, a sinewy shape, warm colors
and the aural delights of a supercharged engine warm the emotions
of those who appreciate sophisticated and engaging automobiles.
The Curve signifies Saturn’s evolution, both in styling
and product. Saturn is growing its portfolio, planning new vehicles
and exploring dynamic, refined designs.
General Motors introduced the Saturn Curve at the North American
International Auto Show. It was one of the vehicles, including
the Pontiac Solstice production model and Chevrolet Nomad concept,
built on GM’s new rear-wheel-drive Kappa architecture.
Design creativity and implementation was a collaboration of GM’s
worldwide resources, driven by GM North America’s Advanced
Design Team and developed by GM’s European Advanced Design
Center in Sweden. The European design influence bolsters the Curve’s
aura of refinement. Final assembly was completed in Italy, with
assistance from Italian coachbuilder Pininfarina.
“The Kappa architecture is a brilliant new canvas on which
to design expressive vehicles,” said Anthony Lo, design
manager. “The Curve’s contemporary style demonstrates
how a great-looking coupe could look on the adaptable architecture.”
Beyond the coupe styling, the Curve’s shape and attention
to detail tap into a growing global design ethos.
“Functionality is paramount, but the look, feel and spirit
of everything from napkin holders to homes is becoming increasingly
more important,” said Lo. “A good design adds warmth
and makes you stop to say, ‘hmmm…’”
The design of the Curve abounds with interesting details that
emphasize its contemporary design aesthetic, as well as its sports
car roots, including roof pillars that are concealed by a wraparound
canopy of glass - creating the look of a “floating”
roof panel.
Also, a front-hinged, clamshell hood is complemented by a rear-hinged
trunk lid. The forward-opening hood is a nod to great sports cars
of the past, while the opposite-opening trunk lid creates interesting
design symmetry when both panels are in the up position. The vehicle
is coated in Mission Silver, a warm color chosen for its liquid
metal appearance.
Relaxed mood
Inside, an open-gate shifter and analog instruments evoke the
feel of a pure sports car, while the interior environment is warmed
and enhanced with “floating” door inserts that feature
color-changing backlighting. This unique lighting effect transmits
a subdued mood throughout the vehicle and is the type of innovative
feature at home in a Saturn.
“Altogether, the Curve has a very sophisticated and relaxed
feel,” said Shuichi Yamashita, lead exterior designer. “It’s
still a fun-to-drive sports car, but the selection of color, materials
and lighting convey maturity and sophistication.”
The Curve’s interior is consistent with the level of workmanship
and refinement that will characterize future Saturn models, including
the upcoming RELAY crossover sport van.
A curved wood center console is the interior’s dominant
feature and is attached to the dashboard via a tongue-and-groove
joint. It also encapsulates the engine instruments. Blonde wood
is used to convey lightness and airiness, while charcoal-colored
leather and terracotta inserts accent the dashboard and upholstery.
An aluminum band running the width of the interior serves as a
divider for the interior’s different elements. A matching
aluminum handle greets those who open the Curve’s doors,
inviting them to plunge into a warm environment that reflects
the friendly nature of the Saturn brand.
Like the front seats, the rear seats consist of a pair of buckets
covered in charcoal leather with terracotta inserts. Entering
the rear seats is easy, thanks to front seats that tilt to add
entry space. The back-lit glow that permeates the interior affects
mood in the Curve’s interior, but also has a safety use:
When the doors are opened, the lighting on the door panels changes
to an orange-red hue to act as a warning light, eliminating the
need for a reflector.
Dynamic performer
Despite its relaxed demeanor inside, the Curve delivers a stirring
sports car experience. Built on GM’s new Kappa architecture,
this sport coupe features rear-wheel drive, independent front
and rear suspensions, and a solid chassis built on the foundation
of full-length hydroformed frame rails. Stampings attached to
the rails form a rigid structure onto which the body panels are
mounted.
Sports car performance is derived from a supercharged 2.2-liter
Ecotec four-cylinder engine that produces more than 200 horsepower
and more than 200 lb.-ft. of torque. The engine features fuel-saving
variable valve timing technology, which is available on some of
GM’s four-, five- and six-cylinder engines. Through the
use of variable engine valve timing, lift and duration can improve
fuel economy, emissions and performance. The transmission is a
Getrag five-speed manual.
The engine and transmission are similar to the powerful combination
found in the new 2004 Saturn ION Red Line.
Unique seven-spoke, outboard-style 20-inch wheels are mounted
to performance tires and fitted to the Curve’s responsive
chassis. Large, 14-inch brake rotors, with twin-piston front calipers
and large, single-piston rear calipers, provide the vehicle’s
stopping power.
The powertrain, chassis and brake system are based on existing
production components.
“As much as the Curve is a driver’s car, it’s
also a reflection of the mindset of the driver,” said Nicho
Vardis, lead interior designer. “As people spend more time
in their vehicles, a warm, personal environment becomes more important.
A car like the Curve, which is both functional and thoughtfully
designed, provides that environment.”
