Lamborghini four-wheel drive
optimizing driving dynamics
and
torque
vectoring:
The Lamborghini Urus’ four-wheel drive system delivers safe,
highly-responsive driving dynamics on every road and surface,
in all weather. A Torsen central self-locking differential
provides maximum control and agility in all driving conditions,
particularly off-road. Torque is split 40/60 to the independent
front/rear axle as standard, with a dynamic maximum torque
of 70% to the front or 87% to the rear, enhancing traction to the
axle with higher ground friction.
The Urus features active torque vectoring via a rear differential,
enabling propulsive power to be instantly distributed to each
individual wheel for enhanced traction, depending on the
driving mode, driving style and the road grip. Torque vectoring
also provides additional steering control: less steering effort
is required, with enhanced agility allowing higher cornering
speeds and a more sporty drive. Yaw motion is controlled,
avoiding understeer into corners and tire slip during
acceleration. In the driving modes STRADA, TERRA (off-
road) and NEVE (snow) torque vectoring reduces understeer
for safe and simple driving. In SPORT and CORSA torque
vectoring allows the Urus to become more agile with a greater
oversteer character: interaction between the four- wheel drive
system and ESC manages oversteer to enable a precise and
fun drive. In SABBIA (sand) mode, the system is calibrated to
guarantee agility and precision on terrains with reduced grip
such as on gravel or sand dunes, making it the ideal mode for
off-road fun.
Rear-wheel steering
The Lamborghini Urus adopts the rear-wheel steering
introduced in the Aventador S over the whole speed range.
The rear steering angle varies up to +/- 3.0 degrees, according
to vehicle speed and driving mode selected: at low speeds the
rear-axle steering angle is opposite to that of the front wheels
(counter-phase steering), effectively shortening the wheelbase
up to 600 mm for increased agility and a reduced turning circle
for increased maneuverability. At high speeds the rear axle
steering angle is in the same direction as the front wheels (in-
phase steering), elongating the wheelbase up to 600 mm for
increased stability and ride comfort as well as optimum driving
dynamics.
Lamborghini DNA
The emotive Lamborghini sound and feel
A 360-degree approach to engine, exhaust system and chassis
ensures daily usability with the reduction of unwanted
mechanical noise, while maintaining the emotive Lamborghini
driving experience and inimitable Lamborghini sound.
Depending on the driving mode selected via the Tamburo, the
V8 engine has been calibrated to vary the sound and feel of the
Urus, from the quietest and most comfortable low-frequency
sounds in STRADA mode, to a sportier and more exciting
Lamborghini sound and feedback in CORSA.
A specially-developed exhaust system also customizes the
sound output dependent on engine speed: at high acceleration,
the Urus produces a more guttural, sporty sound and chassis
feedback.

The Tamburo – Lamborghini driving dynamics control
The Tamburo driving mode selector on the center console
controls all dynamic vehicle systems and allows the selection
of driving dynamics according to surface conditions or drivers’
preference, via STRADA, SPORT and CORSA as well the
additional NEVE (snow) mode. As an option, two further
off-road settings are offered: TERRA (off-road) and SABBIA
(sand).
In STRADA mode the height adapts according to speed to
enhance comfort, while in SPORT the Urus lowers to ensure
stability and precision at all speeds. In CORSA the vehicle
is even more precise and performance oriented with roll at
a minimum. In the three off-road modes, NEVE , TERRA
and SABBIA higher ground clearance allows obstacles to be
safely overcome, with anti-roll bars providing independent
asymmetric movement during cornering to ensure optimal
traction.
The electromechanical active roll stabilization system is being
used for the first time in a Lamborghini. The stabilization
system ensures maximum reduction of the roll angle on bumpy
roads in both a straight line and around corners through active
decoupling of the stabilizer halves, while ensuring the most
agile drive and responsive steering.
The Urus’ specially-tuned damping system incorporates new
damper valves, continually adjusting to different driving
conditions: harder when cornering and softer in a straight
line. The adaptive damper concept is automatically adjusted
to different driving modes through ANIMA, or can be fully
customized by the driver via the EGO mode, choosing the
required rigidity for a very comfortable ride to an extremely
sporty, aggressive setting dependent on driving style and road
conditions.
Exterior design
The Urus is undoubtedly a Lamborghini, taking cues from the
LM002 as well as the super sports cars that are fundamental to
Lamborghini heritage: the Urus has outstanding proportions,
adopting the two-thirds body, one-third window ratio of
Lamborghini super sports cars.
The Urus is a Lamborghini with luxurious space for up to
five occupants. Its short overhangs communicate its strength,
muscularity, dynamically assertive character and commanding
road position.
The imposing front of the Urus clearly identifies the location
of the front-engined power plant within the peaked mound
of the bonnet, reminiscent of the Miura and Aventador, and
accented by diagonal hood lines, found for the first time on the
Countach, that are such a dynamic Lamborghini characteristic.
The proud, low front is underlined by the substantial front
fender: the Urus is the most powerful SUV available.
Large air intakes sporting the hexagonal theme are linked
by a low-level front spoiler, further emphasizing the car’s
aerodynamic efficiency and exceptional performance. The
front lights are sleek, slim and very sporty, set in a horizontal
position and with LED headlights in the familiar Lamborghini
Y shape.
