“As our
first modern rear-wheel drive large sedan, the Kia Quoris offers unprecedented
sporty driving dynamics and premium ride comfort thanks to the optimum harmony
of a powerful V6 engine mated to an eight-speed automatic transmission
featuring shift-by-wire technology, a near-perfect front/rear weight distribution
and an electronically controlled air suspension system with a self-leveling
function,” comments Soon-Nam
Lee, Kia’s Director of Overseas Marketing Group. “In addition, a host of abundant driver assistance
and active safety features completes the Quoris as a true premium sedan.”
“The Quoris stands at the apex of Kia’s available state-of-the-art
technologies and will enrapture drivers who enjoy exhilarating driving
pleasure and premium comfort while taking them beyond the boundaries of ordinary
sedans,” concludes Lee.
Driver
focused rear-wheel drive characteristics
A near-perfect front/rear weight
distribution of the Quoris creates a strong foundation for balanced poise and
excellent steering response, and a sophisticated blend of ride and handling
qualities. Thanks to the adoption of rear-wheel
drive, the front wheels are free of the task of driving the vehicle allowing
the steering to impress drivers with a more natural weight and feel.
Upgraded
and refined V6 power
Quoris will be available in ‘General
Markets’* powered by a significantly upgraded Lambda V6 3.8-liter MPI gasoline engine
with a host of improvements to boost its power, raise its efficiency and
enhance its refinement – making it ideally suited to power the company’s new
flagship.
The normally aspirated twin DOHC, 24
valve, six cylinder engine is equipped with dual continuously variable valve
timing (CVVT) and a variable intake system (VIS )
– enabling it to generate 294 ps at 6,000 rpm and 358 Nm at 4,500 rpm.
Clever engineering ensures that the V6
delivers more than 87% of its maximum torque from just 1,500 rpm for maximum
driveability. The Quoris’s acceleration time to 100 kph (62
mph) is 7.3 seconds, with a top speed of 240 kph (149 mph) – achievements which
are due in part to its low aerodynamic drag – just Cd 0.27.
Ultimately, the upgraded Lambda V6
engine will be available in two versions, the MPI (multi-point injection) unit available
from launch, and a new GDI (gasoline direct injection) unit next year –
depending on market.
* ‘General
Markets’ include the regions of Central and South America, the Caribbean, Asia
(excluding China and Korea), the Pacific, Middle East and Africa.
All-new
eight-speed transmission
Every Quoris will come with Kia’s
all-new eight-speed automatic transmission.
The wide spread of ratios (from 3.665:1 to 0.556:1) guarantees brisk
acceleration and high-speed refinement, while the innovative SBW (shift by
wire) technology, together with the sensitive joystick control, delivers fast,
smooth gear changes.
Replacing conventional wires with
state-of-the-art wireless connection between the TCU (Transmission Control
Unit) and the eight-speed automatic transmission, the innovative SBW technology
ensures precise and near soundless gear shifts.
Whenever the engine is turned off with
the selector left in D (drive) or R (reverse), the SBW automatically switches
the transmission into P (parking mode), improving safety.
A change of transmission control
logics enables the Quoris to be stopped and to start off in second gear. This delivers a fuel efficiency improvement
and the smoothest possible acceleration – typical of a premium vehicle.
Independent
five-link suspension
With its long wheelbase (3,045 mm), wide track (1,616 / 1,634 mm front / rear)
and sophisticated fully independent five-link suspension system, Quoris
will deliver the quality of ride, handling, stability and refinement that
luxury sedan buyers expect.
Mounted on a sub-frame to isolate road
shocks, the front suspension has co-axial coil spring shock absorber units and
a new friction bearing in the steering column to enhance straight-line
stability and steering precision.
At the rear, the suspension subframe
also houses the rear differential. The
coil springs and shock absorbers are separate units and the set-up gives the
wheels 1.4 degrees of negative camber for improved cornering ability, with
geometry that minimizes toe-in changes for consistent handling characteristics.
The high-performance HPD dampers
fitted front and rear, have sliding ASD (Amplitude Selective Damper) valves
that vary their stiffness to adapt to different driving conditions. When cruising on smooth well-paved roads, the
dampers are softer – enhancing ride comfort.
During sporty driving damping stiffness is increased to provide more
responsive handling.
Electronic
air suspension delivers ultimate luxury
For even greater comfort, Quoris will
be available with an electronically controlled full air suspension system as
standard on the top specification model.
The regular dampers are replaced by Adaptive Air Dampers which are
pressurized from an air storage tank and a separate air compressor mounted in
the engine bay, ahead of each front wheel.
A choice of four fully automatic
driving modes (Eco, Normal
The Sport mode immediately facilitates
sporty driving dynamics by making the dampers stiffer, increasing the weight of
the steering and quickening the engine’s throttle response to generate more
torque faster and speeding up the gear shift timings.
Self-levelling, the air suspension system
can operate in Automatic mode or allows the driver to select Normal
mode (constant ride height), Low mode (down 15 mm) and High mode (up 30 mm), adjusting
the vehicle height and ground clearance to ideally suit road conditions.
When driving faster than 120 kph for
more than 10 seconds, the self-leveling system lowers the Quoris by 15 mm
reducing the ground clearance to 130 mm from regular 145 mm. Aerodynamics is consequently improved,
resulting in high-speed acceleration and fuel efficiency improvements.
At the opposite end of the system’s
operating range, when approaching unpaved roads, the driver can choose to raise
the Quoris’ ground clearance by 30 mm to 175 mm, enhancing ride comfort.
Facing the
driver, the three-spoke, leather-wrapped steering wheel features powered
adjustment for height and reach. The
electric power steering is speed-sensitive and requires just 2.81 turns
lock-to-lock (air suspension models) or 2.98 turns (regular suspension models),
with a city-street-friendly turning circle of 12.08 or 11.30 meters.
The
driver-oriented cabin places the engine start/stop button to the right of the
wheel and the space efficient control for the EPB (Electric Parking Brake) is
located near the gear selector, ensuring effortless activation and release of
the brake.
Taking HAC (Hill-start
Assist Control) one stage further, Quoris will also be equipped with AVH
(Automatic Vehicle Hold). AVH maintains
the braking pressure to prevent roll-back on hills. Unlike HAC, this new system also applies the
brakes during a temporary stop, so that the driver does not need to keep
pressing on the brake pedal to hold the vehicle. When the driver pushes the accelerator, AVN is
automatically released.
If the car has stopped
for more than 10 minutes, AVH is automatically switched off and the system
engages the EPD to secure the vehicle in the parking mode.
Clever
driver assistance technology completes premium driving experience
In addition
to the characteristics of a rear-wheel drive, together with advanced powertrain
technologies, the Quoris offers a host of advanced driver assistance features
and technologies such as HUD (Head Up Display) and a Haptic steering control – as
well as Advanced Smart Cruse Control (ASCC), Lane Departure Warning System
(LDWS), Blind Spot Detection (BSD) and Lane Change Assist (LCA).
Both the HUD
and a rotary type Haptic remote control on the steering wheel help the driver
remain focused on the road, which is particularly beneficial during high speed maneuvers.
The HUD
(Head-up Display) presents a variety of information discretely on the
windshield in the driver’s sight line, enabling it to be assimilated without distraction
from the road ahead.
Featuring the
latest technology of its kind, the Quoris’ HUD boasts a segment-leading variety
of information, presented in a variety of colors. The information displayed by the HUD includes
speeds, turn-by-turn navigation information, road warning and warnings from the
car’s ASCC, LDWS, BSD and LCA systems.
Some outdated
HUDs in the automotive marketplace offer only a few colors. Kia’s new system offers displays with three-dimensional
effects backed up by 65,000 colors and adjusts the brightness of the display to
suit local ambient light levels. Settings
of the HUD displays such as the display location, brightness and letter sizes
are conveniently adjustable.
Through the Haptic
remote control, the driver can select a variety of menus and change the settings
of the HUD, route information and the vehicle systems such as headlamp escort,
door lock/release, AVSM and turn lamps.
Ultra-high
tensile steel brings strength and refinement
The foundation for the highest
standards of ride, handling, refinement and crash safety achieved by Quoris is
its all-new bodyshell which is was created using eight types of high-strength
steel that account for more than 70% of its vehicle structure.
Hot stamping is used to heat steel to
900º C, rapidly cool the steel and simultaneously press immensely strong
components for the center pillar and roof side outer rail – improving
crashworthiness.
The resulting bodyshell has exceptional
strength, torsional and flexural rigidity, together with modest weight and
robust impact resistance. The stiff
bodyshell enables the independent suspension to operate with maximum
efficiency, delivering a supple, controlled and responsive ride/handling
balance.
While engineering the remarkably
robust bodyshell, Kia engineers paid diligent attention to detail to achieve
the Quoris’ outstanding aerodynamic rating of Cd 0.27.
The front grille incorporates an
Active Air Flap (AAF), which closes at speed to minimize drag generated by
admitting cooling air to the radiator and engine bay. This drag reduction improves fuel efficiency
and acceleration at higher speeds. Airflow
smoothing underbody panels are mounted beneath the nose, engine bay and
cabin. Air deflectors are fitted ahead
of each wheel.
The AAF, the underbody-full-cover and
air deflectors all contribute to achieving the Quoris’ class-leading Cd figure.
Taking
Kia vehicle refinement to a new level
Kia engineers were determined to make
new Quoris one of the very best-in-class for refinement – matching or beating established
premium brand sedans. This level of
refinement has been achieved through a variety of technologies and a great deal
of attention to the smallest details.
The windscreen and door windows
feature extra thick, specially laminated, five-layer, sound-proofing glass. The
block-type engine mountings have larger hydraulic mass dampers.
Driver comfort is assured by the
powered, heated and ventilated front seats trimmed in premium Nappa leather,
and the premium ambience is reinforced by the superfine suede cabin head
lining.
For Quoris, Kia uses a two-part
prop-shaft to transfer power to the rear differential. Supported by an aluminum center bearing, the
shaft is fitted with a universal joint and rubber couplings on both the
transmission and the rear differential side to dampen vibrations.
“Quoris demonstrates once again our brand’s power to surprise. Our new flagship sedan is a remarkable car
which will entice an entirely new customer group of progressive,
forward-looking consumers to our brand for the first time,” concludes Mr. Soon-Nam Lee.
