New platform offers a stiffer, more agile chassis for Subaru global performance icon
New torque-vectoring system reduces understeer
New 268-hp 2.0-liter direct-injection turbo BOXER engine
New standard 6-speed manual transmission
New Sport Lineartronic® CVT with manual modes
Subaru of America, Inc. introduced
the 2015 WRX, a more powerful and better handling version of the brand's
iconic high-performance model, at the Los Angeles Auto Show. Powered by
a new 268-horsepower 2.0-liter direct-injection turbo BOXER engine, the
2015 WRX debuts the model's first six-speed manual transmission and a
new, optional performance automatic transmission, the Sport Lineartronic
CVT with two manual modes.
With its bold new wide-body sedan design and expanded performance
envelope, the 2015 WRX marks a major evolutionary step for the
rally-bred performance car that has become a global automotive legend.
For 2015, the Subaru WRX employs a new torque-vectoring system that
supplements the standard Symmetrical All-Wheel Drive system. Torque
vectoring allows for improved cornering speeds and handling. The new and
stiffer chassis, larger brakes, performance-tuned suspension and a
driver-focused interior remain integral to the WRX performance
character. The new powertrain also yields higher fuel efficiency than
the previous model.
At the same time, a roomier interior, upgraded cabin comfort and
materials and a wide array of new user technologies give the new WRX a
more refined feel. A harman/kardon® premium audio system is offered for
the first time in a WRX.
The 2015 WRX design deftly blends an aggressive stance with a
sophisticated sport sedan theme. The new WRX features a much bolder
front design with a deep front spoiler and unique grille. The wide-body
stance seen on the previous model is enhanced with new, standard 17-inch
wheels. The hood, front fenders, rear doors and quarters, bumpers,
headlights and taillight clusters are all unique to the 2015 WRX.
Other new performance-oriented details include foglight surrounds with a
carbon fiber-like pattern and vertical front fender vents that feature a
bright garnish and a mesh screen. Higher-grade models use new LED
low-beam headlights; halogen lights are used on other models. The side
sill spoilers that help to visually lower the car also help protect the
doors from rock chips.
New standard 17-inch wheels feature a more aerodynamic design. At the
rear, LED taillights, a diffuser, LED center high-mount stoplight (CHMS)
and an available lip spoiler leave a distinctive signature.
The new WRX body structure makes greater use of high-tensile strength
steel than the previous model and features special stiffening elements
at key locations. Combined with the new Electronic Power Steering
system, specially tuned suspension and 235/45 R17 94W Dunlop SP Sport
Maxx RT tires, the stiffer chassis yields steering response that was
benchmarked against top-handling sports cars.
Based on the engine used in the new 2014 Forester 2.0 XT, the WRX
version uses different cams and higher-rate valve springs, among other
enhancements, to extend the performance envelope. The new 6-speed manual
transmission provides a wider ratio spread than the previous 5-speed
and incorporates several performance and durability improvements for
this high-performance application, including carbon synchronizers on
first and second gears.
New Sport Lineartronic CVT
The 2015 WRX introduces the option of a new automatic transmission
engineered to enrich the performance-driving experience. The new Sport
Lineartronic CVT combines the benefits of a continuously variable
transmission (high fuel efficiency, ultra-smooth driving character) with
the choice of stepped automatic shifting eight pre-selected ratios
(when in Sport Sharp mode) and also 6-speed and 8-speed manual shifting
modes using steering wheel paddle switches.
Models with the Sport Lineartronic CVT also feature Subaru Intelligent
Drive (SI-DRIVE), a powertrain performance management system that allows
the driver to tailor the vehicle's driving characteristics by choosing
from among three selectable modes – "Intelligent," "Sport" and "Sport
Sharp" – using a switch on the flat-bottom steering wheel
Two Versions of Symmetrical AWD
When equipped with the 6-speed manual transmission, the 2015 Subaru WRX
uses the brand's Continuous AWD version of Symmetrical All-Wheel Drive. A
viscous coupling locking center differential nominally distributes
torque 50:50 front to rear, and Vehicle Dynamics Control (VDC) provides
stability and traction control. Should slippage occur, this system
transfers more power to the wheels with the best traction.
The new Sport Lineartronic CVT is teamed exclusively with the Variable
Torque Distribution (VTD) version of Symmetrical All-Wheel Drive. A
planetary gear-type center differential and an electronically controlled
hydraulic transfer clutch control torque distribution between the front
and rear wheels. Under most conditions, VTD splits the torque 45:55,
with the rearward torque bias contributing to handling agility. The VTD
system continually optimizes torque distribution in response to driving
conditions and input from steering wheel angle, yaw and lateral g-force
sensors.
Premium Cabin
A one-inch longer wheelbase than the previous WRX is a factor in
providing a markedly roomier cabin in the new model. The windshield is
more raked than before, with the A-pillar pulled forward nearly eight
inches at the base for better forward visibility, aided by a lower
dashboard and narrower A-pillars. Higher seating hip points, lower side
sills and wider-opening doors make ingress/egress easier. Rear seat
passengers gain nearly two inches of legroom, and trunk capacity is
increased. A standard 60/40-split fold-down rear seat extends the WRX
sedan's versatility.
The high-performance feel starts as soon as the driver enters the 2015
WRX and grips the new flat-bottom, leather-wrapped steering wheel, which
offers tilt and telescoping adjustments. The wheel integrates switches
for audio and Bluetooth® control.
Rich-looking appointments and details abound, including soft-touch
materials for the dashboard, door trim and center console armrest.
Numerous compartments located in and around the center console hold all
manner of personal items, such as phones, USB drives and MP3 players.
The available power sunroof opens one inch farther than on the previous
WRX.
The dual gauge instrument layout features a 3.5-in. LCD central screen
to display various functions, including oil level, remaining washer
fluid and selected gear ratio. A new multi-information central display
with 4.3-in. LCD screen provides a multitude of vehicle system
functions, including a rear camera display, a boost gauge display,
audio, Bluetooth and climate control settings, and a VDC screen showing
traction control operation. The display can provide a vehicle self-check
and maintenance reminder.
.
The new WRX 2.0-liter, 4-cylinder BOXER engine uses a combination of
direct fuel injection, high compression (10.6:1), Subaru Dual Active
Valve Control System (D-AVCS), a twin-scroll turbocharger and an
intercooler to achieve outstanding performance and high efficiency. The
engine produces 268 horsepower at 5,600 rpm, accompanied by a broad
torque curve that peaks at 258 lb.-ft. over a 2,000-5,200 rpm engine
speed range.
Whiplash-reducing front sport seats, covered in a new high-grip fabric,
feature separate tilt- and height-adjustable head restraints, a change
from the seats with integrated head restraints used before. Leather is
available, as is an 8-way power driver's seat.
Amenities that reflect the 2015 WRX's refined sport sedan positioning
include standard automatic climate control and available Keyless Access
with Push-button Start, heated front seats, power driver's seat, and a
440-watt, 9-speaker harman/kardon premium audio system and navigation
with Aha® smartphone integration.
Specially designed for the 2015 WRX, the rear doors and fenders continue
the model's wide-body stance in a rakish new profile. The Subaru
hexagonal grille is flanked by narrower headlights designed to evoke a
raptor's stare. The functional hood scoop, which supplies the
intercooler with fresh air, is now set more deeply into the hood to
provide better forward visibility.
