The Lamborghini Urus is much lighter than most of its competitors (i. e the BMW X6M, Bentley Bentayga and Rolls-Royce Cullinan, but not the Porsche Cayenne) at less than 2,200 kg (4,850 lb) as quoted by the manufacturer mainly because of the extensive usage of carbon fibre reinforced polymer, although it is based on the same platform as the Audi Q7, Bentley Bentayga, Porsche Cayenne, and Volkswagen Touareg. The engine is rated at a maximum power output of 478 kW (641 hp; 650 PS) at 6,000 rpm and maximum torque of 850 N⋅m (627 lb⋅ft) at 2,250–4,500 rpm. The Urus has a front-engine, all-wheel-drive layout, and a top speed of 305 km/h (190 mph) making it one of the world's fastest production SUVs. The Urus can accelerate from 0–100 km/h (62 mph) in 3. 6 seconds and 0–200 km/h (124 mph) in 12. 8 seconds. Lamborghini has developed the world's largest set of carbon ceramic disc brakes for the Urus, with 440 mm (17. 32 in) discs in the front and 370 mm (14. 57 in) discs in the rear using ten-piston callipers at the front and single-piston callipers at the rear. The all-wheel drive system of the Urus under normal driving sends 40 percent of the engine's torque to the front wheels and 60 percent to the rear wheels. It also uses torque vectoring to send as much as 70 percent to the front or 87 percent to the rear when necessary. The SUV also features rear-wheel steering and an air suspension system that can provide a maximum of 250 mm (9. 8 in) of ground clearance for off-road use. The SUV will be available with an optional off-road package, which includes modified front and rear bumpers that are better suited to the task. The Urus, like all of Lamborghini's current offerings, will feature a selection of driving modes, which adapt the suspension to improve the car's performance in various driving conditions. The Lamborghini Urus will feature Strada (street), Sport, Corsa (track), Terra (dirt), Sabbia (sand), and Neve (snow) driving modes, with the latter three possibly only available on the off-road package offered. The Urus will have a seating capacity of four to five people.
