Despite its incredible speed on smooth roads, Lamborghini saw fit to equip the Urus Performante with a new Rally Mode for optimal performance on rougher surfaces. In this mode, oversteer is more readily initiated. Rear-wheel steering improves agility and front/rear carbon-ceramic brakes slow the large SUV down more effectively.The DBX707 also has a 4.0-liter twin-turbo V8 but makes more power (697 hp) and more torque (663 lb-ft) than the Urus Performante. At 3.1 seconds to 60 mph and 3.3 seconds to 62 mph, the two are impossible to separate up to that speed. But in the DBX707, the fun only stops at a ballistic 193 mph – no other current SUV is as fast. A nine-speed wet-clutch automatic transmission and a rear-biased all-wheel drive are standard. Interestingly, Aston decided against rear-wheel steering for the DBX707 as it believes responses are more linear without it. In our test drive of this super SUV, we marveled at the way it shrinks around the driver with consistent feedback from the chassis and a surprisingly supple ride.The Lambo is over 200 pounds lighter, and its Pikes Peak record speaks volumes, but only a back-to-back test drive will determine which one has the edge. Both are supremely talented performance SUVs.
