6 things you should know about the Lamborghini Urus

Lamborghini has finally revealed its second SUV in history. The road-oriented vehicle has a 641-horsepower twin-turbo V8 and highly creased body panels. There are plenty of interesting factoids packed into its four-door shape. We highlight the most interesting of them, here. It's named after a breed of cattle. Though many Lamborghinis have been named after specific fighting bulls, this one is named after an entire breed. The extinct breed is called urus, or sometimes aurochs, that is closely related to Spanish fighting bulls of today. It's the first Lamborghini with active roll control. When a car gets tall and heavy, it wants to lean a lot more when cornering. To counter that, Lamborghini fitted the Urus with an active roll control system to help keep the body flat going through turns. It's also one of a number of technologies meant to improve handling, such as adaptive damping, rear-wheel steering ( borrowed from the Aventador S) and torque vectoring on the rear differential. It has huge wheels and brakes. Standard wheels on the Urus are 21 inches, but for those with a desire for bigger dubs, there are optional 23-inch models. These wheels are stopped by standard carbon ceramic rotors. The fronts are 17.3 inches in diameter, and the rears are 14.5 inches. It has the best weight-to-power ratio of any SUV. Besides having the highest claimed top speed for an SUV, and acceleration on par with the 707-horsepower Grand Cherokee Trackhawk, Lamborghini claims the Urus has the best weight-to-power ratio of any SUV on the market. That ratio, with the SUV's roughly 4,850 pound curb weight and 641 horsepower, is 7.57 pounds per horsepower. It is worth noting that the aforementioned Grand Cherokee Trackhawk is still close with a ratio of 7.59 pounds per horsepower. It can be mostly rear-wheel drive, but not fully. The big Lambo is all-wheel-drive all the time, with its Torsen center differential providing a default torque split of 40 percent to the front, and 60 percent to the rear. This can change all the way up to 87.5 percent to the rear depending on conditions, or it can shift 70 percent of the torque to the front. Its chassis is all steel and aluminum. Unlike the Lamborghini's sports cars that use extensive carbon fiber in the chassis, either for the passenger cell in the case of the Aventador, or for reinforcement as in the Huracan, the Urus has a steel and aluminum chassis.

Weekly Recap: Autonomous driving goes commercial in Nevada

Nevada granted Daimler Trucks North America the first license to run an autonomous commercial vehicle on public roads in the United States Tuesday, marking another milestone in the technology's rapid advancement. Gov. Brian Sandoval and Daimler truck chief Wolfgang Bernhard promptly used the license to lap Highway 15 near Las Vegas in a newly revealed Freightliner Inspiration Truck. It was a clear signal that autonomous driving is big-rig reality, though it's still a long way from widespread use. Nevada certified two of Daimler's Freightliner Inspiration Trucks, which use the company's Highway Pilot system with a stereo camera, radar, and lane-keeping collision-prevention features to regulate the brakes and steering. The radar component has a long-range sensor that can cover 820 feet at an 18-degree angle and a shorter-range unit that stretches 230 feet at a 130-degree angle. The Inspiration trucks are based on the existing Freightliner Cascadia Evolution model used on US roads. In addition to the autonomous technologies, it also has futuristic design cues, including blue lighting in the front and a new hood and grille. While there are only two Freightliner Inspiration trucks in existence, Daimler expects to bring the Highway Pilot system into mass-produced big rigs by 2025, in time to capitalize on the market's predicted growth. The German truckmaker predicts the global hauling market will triple by 2050, and the United States will be a key part of that growth. Trucks carry 69.1 percent the nation's domestic freight tonnage and hauled 9.7 billion tons of freight in 2013, according to the American Trucking Association. Daimler expects autonomous driving to augment this growth, and perhaps evolve the role of the truck driver. Still, the company points out autonomous tech is not meant to replace drivers, but to assist them and relieve fatigue and monotony on long hauls. The driver has to stay in control for passing, in city traffic, and when hooking up the trailer. The company said autonomous driving also offers the potential for improved fuel economy – tests showed a five-percent gain – and lower maintenance costs. Daimler also said the technology could reduce congestion on the road. Much of this is attributable to the constant flow of traffic, which is aided by autonomous driving. While the benefits are becoming increasingly apparent, autonomous technology is still met with skepticism.

'Born of a Blue Sky' brings the Amelia Island Concours to you

The Amelia Island Concours d'Elegance has more clout every year and is getting a reputation as Pebble Beach minus the madness. Held in March this year, it celebrated Ducati and the 50-year anniversaries of Lamborghini, the Corvette Sting Ray, Porsche 911 and the Ford GT40.
Justin Lapriore was there, and seemingly everywhere, getting footage of the various wares on display on the lawns and the sand and the runway. The resulting video, Born of a Blue Sky, is a 16-minute survey of some of the finer sights and plenty of engine sounds. Check it out below.
