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.

Lamborghini walks us through improvements it made to the Huracan

LE CASTELLET, France — Lamborghini's updated Huracan EVO2 will make its competition debut during the 2022 season of the Super Trofeo one-make series. Visually, it gains a new-look design that blazes the path future models — including production cars — will follow in the coming years. There's more to it than a face-lift, and we sat down with Leonardo Galante, the man in charge of technical development for Lamborghini's racing arm, to get the full scoop on the changes made. "It's a big step from EVO to EVO2, and we focused on three main pillars," Galante told us at the Paul Ricard track. Design is the first; aerodynamics is the second, and it's closely linked to design; braking performance is the third. Customers and enthusiasts will notice design before any of the mechanical changes, so Galante's team worked directly with Centro Stile, the company's in-house design department, to update the Huracan. The lights are thinner on both ends, and the rear units are embedded in a housing that echoes the Countach's back end. Air curtains are now positioned on either side of the front fascia, while a redesigned diffuser dominates the Huracan's rear end. Centro Stile and Squadra Corse had an equal influence on these updates. "We learned a lot in terms of shapes, about how to make a car look beautiful, and designers learned a lot about the principles of aerodynamics," Galante explained. "We worked together to define the best shapes to generate an efficient aerodynamic profile. We want to generate as much downforce as possible while creating as little drag as possible." Sculpting a car's aerodynamic profile isn't as straightforward as merely adding wings, spoilers, vents, and ducts to keep it glued to the ground around a turn. Galante stressed the quality of the downforce generated by the various add-ons is just as important as headline-grabbing figures. His aim was to keep the car as stable and predictable as possible, even when the weight balance shifts under heavy braking from triple-digit speeds. Feedback provided by Super Trofeo competitors since the beginning of the series helped his team dial in the right amount of downforce.

When something is very good, or when something is very bad, I get immediate feedback. This is a very good part of my job," he said. Braking was one of the areas he wanted to improve.

Get a closer look at the 830-horsepower Lamborghini SCV12 track car

Lamborghini has just released a set of photos and video of its upcoming SCV12 hypercar, giving us a clearer look. The track-only machine does look similarly sized to the Aventador, but it apparently doesn't share much with the road car. The closest relation is has to the Aventador is the use of a naturally aspirated V12 engine. But this one is the most-powerful naturally aspirated V12 ever built by Lamborghini. It makes 830 horsepower, and that's partly made possible by the car's aerodynamics and intake manifold. The car features a huge roof intake scoop, and the hood has several vents that channel air to the scoop. At speed, these components create a supercharging effect, pushing more air into the engine than what it would pull in naturally. The engine is connected to a six-speed sequential transmission and powers only the rear wheels. Previous reports have mentioned the SCV12 will get a trick limited-slip differential. The SCV12's chassis and aerodynamics have other impressive details. The car produces more downforce than a GT3-class race car thanks to its huge custom carbon fiber rear wing and array of dive planes and splitters. Lamborghini says the SCV12 uses a unique carbon fiber chassis that uses other components such as transmission as structural members. The rear pushrod suspension is actually partly connected to the transmission. The SCV12 also features magnesium wheels wrapped in slick Pirelli tires specific to the Lamborghini. Besides the car, buyers of the SCV12 will also get to participate in a variety of driving programs and famous racetracks and get coaching from five-time Le Mans winner Emanuele Pirro. Technical support will be provided by Squadra Corse. Details such as pricing and number of units have yet to be revealed, but we won't have long to wait as Lamborghini will unveil the car later this summer. We wouldn't be surprised if the car costs well into the seven-figure range. Previous reports have suggested only 40 will be built. Related Video:
