Lamborghini Urus, Just urus-kan one for us
Automobili Lamborghini launches its third model the Lamborghini Urus, the first Super Sport Utility Vehicle, and creates a new niche in the luxury segment with benchmarking power, performance and driving dynamics, unparalleled design, luxury and daily usability.
The Lamborghini Urus features a 4.0 liter V8 twin-turbo engine delivering 650 hp (478 kW) at 6,000 rpm, maximum 6,800 rpm, and 850 Nm of maximum torque already at 2,250 rpm. With 162.7 hp/l the Urus claims one of the highest specific power outputs in its class and the best weight-to-power ratio at 3,38 kg/hp.
The Lamborghini Urus accelerates from 0-100 km/h in 3.6 seconds, 0-200 km/h in 12,8 seconds and with a top speed of 305 km/h it is the fastest SUV available.
The Lamborghini Urus is as much a luxury SUV as the most powerful, with a super sports car dynamism to be enjoyed by both driver and passengers.
Its low-line coupé styling and commanding road position belie the very comfortable ride, higher ground clearance, and luxurious space within together with the latest technologies. The Urus provides easy driving in the city, maximum comfort during long journeys, thrilling super sports car dynamics on the road and track, and versatile off-road abilities in a range of environments. The Lamborghini Urus has a dual personality: it is multi-dimensional. It can be specified to be as sporty or as elegant as the owner wishes, and can equally be used as a daily luxury drive or provide an exhilarating super sports experience.
As has long been the tradition at Lamborghini, the name Urus is derived from the world of bulls. The Urus, also known as Aurochs, is one of the large, wild ancestors of domestic cattle. The Spanish fighting bull, as bred for the past 500 years, is still very close to the Urus in its appearance.
The Lamborghini Urus sports a new front-mounted, 4.0 liter petrol V8 twin-turbo aluminum engine. The choice of a turbo engine, the first in a Lamborghini, reflects the desired usage range of the Urus. Especially in off-road conditions a high level of torque at low revs is necessary and can be guaranteed only by such an engine, providing optimal engine responsiveness and efficiency. Delivering 650 hp (478 kW) at 6,000 rpm, maximum 6,800 rpm and a maximum torque of 850 Nm at 2,250-4,500 rpm, the Urus has a specific power of 162.7 hp/l. With a curb weight lower than 2,200 kg the Urus is the SUV with the best weight-to-power ratio at 3.38 kg/hp.
The Urus accelerates from 0-100 km/h in 3.6 seconds, 0-200 km/h in 12.8 seconds and reaches a top speed of 305 km/h. Braking is no less impressive: the Urus decelerates from 100 km/h to 0 in 33,7 m.
The compact engine optimizes the car’s center of gravity through its low-mounted position. With a central turbo charger layout close to the combustion chambers, optimum engine responsiveness is assured. The twin-scroll turbochargers run in parallel, providing maximum power in full-load conditions. This reduces turbo lag and ensures maximum torque and smooth provision of power throughout the torque curve, even at low speeds. Two separate exhaust flows complement the cylinder firing sequence by eliminating cross-interference in the exhaust gas cycle. With a double overhead camshaft and variable valve timing, new cylinder-liner technology reduces weight while ensuring the highest performance from the eight-cylinder engine. Cylinder deactivation reduces fuel consumption for a perfect balance between vehicle performance and efficient engine function.
Transmission and gearbox
The Lamborghini Urus features an automatic eight-speed gearbox. The compact and efficient electro-hydraulically controlled planetary gearbox is tuned to provide very short low gear ratios and longer high gears. A highly efficient slip-controlled converter lock-up clutch and specially-developed torque converter guarantee a highly responsive engine, with an exceptionally powerful starting ratio for exciting acceleration, and high speed at low engine revs for optimal fuel consumption and emissions. Highly efficient gear braking is also assured.
Lamborghini four-wheel drive and torque vectoring: optimizing driving dynamics
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 Lamborghini 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.
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.
