Kia press release :
ATLANTA, March 19, 2010 – Following the
official grand opening ceremony of Kia’s first U.S.-based manufacturing
facility in West Point, Georgia, Kia Motors America (KMA) today debuted
the new 2011 Sorento SX crossover during a press conference at the 2010
Atlanta Auto Show. The all-new Sorento has exceeded expectations since
going on sale in early January, and now the new SX brings the CUV to
new levels of comfort, convenience, technology and design and will
arrive in dealerships later this summer. The first vehicle to roll off
the line at Kia Motors’ recently opened state-of-the-art manufacturing
facility in West Point, Georgia, the 2011 Sorento is a true symbol of
Kia Motors’ $1 billion commitment to both the state of Georgia, the
United States and North America.
critical and consumer acclaim, Sorento has surpassed all expectations
in only its first two months on the market, leading both January and
February sales and helping achieve record-breaking sales for Kia Motors
America,” said Michael Sprague, vice president, marketing of KMA. “The
addition of the 2011 Sorento to the Kia lineup has helped bring new and
more affluent customers into our showrooms. And with the addition of
the new SX trim we hope to expand Sorento’s appeal to even more
consumers looking for a comfortable, sophisticated and well-equipped
With a streamlined and attractive look,
the 2011 Sorento represents a modern CUV that is just the right size
for today’s consumer. With swept-back lines and angled windows, large
flared-back headlamps and prominent fog lamps, the view from the front
conveys strength and power. From the rear, the rounded back and tail
lamps set prominently within the lift gate express the same forceful
attitude and strength. Offering a more muscular stance, the SX receives
revised front and rear fascias to exude additional authority while
added chrome to the exhaust outlet, LED tail lamps and redesigned
18-inch alloy wheels with a hyper silver paint finish increase its
luxurious exterior appeal.
Originally available
in two trim levels, LX and EX, SX adds an enhanced dimension to Sorento
with styling that adds an edgier attitude and comes standard with a
host of luxury, convenience and technology features throughout. In
addition to the smart key with push button start, leather-wrapped
steering wheel and shift knob, telescopic steering wheel, heated side
mirrors, automatic up/down driver-side windows and privacy glass found
standard on all EX models, upgrading to the new SX trim will further
spoil its occupants. Driver and passengers will benefit from
leather-trimmed seats, heated front seats, electrochromatic mirror with
Homelink® and a voice-activated navigation system with back-up camera.
addition to the impressive array of standard technology features found
on all Sorento models, including an AM/FM/CD/MP3 audio system with
SIRIUS Satellite Radio capabilities, auxiliary and USB audio input
jacks for connecting personal MP3 players, and Bluetooth®2
connectivity with steering wheel-mounted voice activation controls to
enable hands-free operation for all compatible mobile phones, the SX
also comes standard with an Infinity® Audio surround sound system with
10 speakers for a truly enhanced listening experience.
the level of refinement and sophistication further, the SX interior
benefits from a unique metallic gauge cluster with a stitched meter
housing, accent interior illumination and stainless steel pedals.
Chrome-finished roof rails, a metallic accent along the greenhouse and
front and rear stainless skid plates on the outside complete the look.
A panoramic sunroof also is available to enhance the feeling of
spaciousness and adds to Sorento’s modern appearance.
sacrificing the space, comfort and ride that the current Sorento
already offers, Sorento SX will employ the same unibody design with the
ability to comfortably fit up to seven passengers. An overall length of
183.9 inches and overall width of 74.2 inches with substantial
headroom, legroom and cargo capacity effortlessly accommodates both
passenger and cargo needs for all drivers. Sorento SX will, however, be
nearly half of an inch lower to the ground for a subtly sportier
appearance while the lower center of gravity allows improved handling
and aerodynamics.
The Sorento SX also features
DFD (Dual Flow Damper) shock absorbers typically found on more
expensive vehicles. The DFD shocks, which have been specially matched
to Sorento’s MacPherson strut front suspension and the fully
independent mulit-link rear suspension, provide excellent handling
characteristics without the harsh ride qualities typically associated
with sport-tuned suspensions.
The SX comes
mated to Sorento’s more powerful 3.5-liter V6 engine, providing
best-in-class 276 horsepower and 248 pound-feet of torque, more
powerful than the Ford Edge and Chevrolet Equinox V63.
Coupled to a new six-speed automatic transmission, the V6 offers ample
power and improved fuel efficiency. This all-new six-speed automatic
transmission is a proprietary design for Kia Motors that was designed,
engineered and built specifically for Kia vehicles, making the brand
one of only three manufacturers to employ such a transmission.
further meet consumer needs, the engine can be mated to either front-
or all-wheel-drive configurations, the latter coming with a locking
center differential to evenly distribute power to all wheels while
operating the vehicle at low speeds during more severe weather
conditions. Drivers also will benefit from a standard Anti-lock Braking
System (ABS), Electronic Stability Control (ESC), Hill Start Assist
(HAS) and Downhill Brake Control (DBC), offered on all Sorento trims.
Industry-Leading Warranty
2011 Sorento SX is covered by Kia’s comprehensive warranty program,
which offers unprecedented consumer protection. Included in this
program are a 10-year/100,000-mile limited powertrain warranty, a
five-year/60,000-mile limited basic warranty and a
five-year/100,000-mile anti-perforation warranty. A
five-year/60,000-mile roadside assistance plan also is part of the
comprehensive vehicle coverage.
Kia Motors is
in the midst of a dramatic, design-led transformation, which has been
delivering dynamically styled vehicles in several important segments at
exactly the right time, contributing to the brand’s continued gains in
U.S. market share. With two new vehicle introductions and several other
key initiatives planned for 2010, Kia is poised to continue its
momentum and will continue to build the brand through design
innovation, quality, value, safety features and with new technology
such as UVO powered by Microsoft®4 infotainment system (to
be available in select Kia models in the U.S. beginning in summer
2010). The launch of the all-new 2011 Sorento CUV, the official vehicle
of the NBA, further enhances the lineup and is now in dealerships.
