Active Torque Split
Models that use it: All 2014 models, and the 2015 WRX, that are equipped
with the Lineartronic® continuously variable transmission (CVT).
不过确实查到有些新闻报道说是VTD AWD。

2015 SUBARU WRX® MAKES WORLD DEBUT AT LOS ANGELES AUTO SHOW
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
LOS ANGELES, Nov. 20, 2013 – Subaru of America, Inc. today 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.
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.
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.
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.
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.
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.
Subaru Safety
Subaru's renowned safety package uses the brand's proven Ring Shaped Frame
Reinforcement body structure, which has been shown to excel in the new small
overlap test by the Insurance Institute for Highway Safety (IIHS). In the
cabin, a driver's knee airbag is added to the roster of safety features that
includes front side pelvis/torso airbags and side curtain airbags that
offer front and rear outboard seat coverage.
