As expected, the Urus would have to be based on the same platform that is slated to underpin the next Volkswagen Touareg, Audi Q7, Porsche Cayenne and Bentley EXP 9 F (if similarly approved) in order to make good business sense. Unfortunately, that new PL73 architecture is made principally of steel, a material that Lamborghini has been getting away from in favor of new types of carbon fiber construction. In order to keep weight down – Lambo is targeting 4,400 lbs for the Urus, significantly less than its potential competitors – it would need to make other components out of carbon to compensate.
That covers the mass side of the power-to-weight ratio that is integral to any performance vehicle. As for the power, Reggiani says the company has yet to make a final decision. The last time Lamborghini made an SUV – the legendary LM002 "Rambo Lambo" – it was powered by the same high-revving V12 as the Countach, lending to speculation that the Urus could incorporate the new V12 from the Aventador or the V10 from the Gallardo. Reggiani, however, indicates that the new twin-turbo V8 powering the latest Audi RS models and the Bentley Continental is a more likely choice, given that it would help keep weight down and provide more low-end torque than the naturally-aspired 10 or 12-pots the Raging Bull marque currently produces for its sports cars.
