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 Aventador spotted with more aggressive look

The Lamborghini Aventador LP700-4 has been a huge success for the Italian automaker. The big, burly V12 supercar propelled Lamborghini to record profits a few years ago and the automaker wants to ensure that the Aventador remains relevant with a minor facelift that makes it look even more aggressive. Photographers caught an Aventador testing at the Nurburgring and the vehicle looks like a toned down Aventador LP750-4 SV. At the front, the prototype has smaller air intakes on either side of the front grille, of much the same angular design as the more powerful SV. These replace the unobstructed, larger square-like intakes on the regular model. The prototype still has the same overall profile as the current model. The changes at the back of the prototype are more dramatic. The rear wing is still the same shape and size, but the rear vents, which sit just below the taillights, appear to be smaller and more rectangular. The diffuser, which protrudes out of the prototype's rear end, is closer to the one found on the SV than the more restrained one on the normal Aventador. The exhaust outlet on this test vehicle is also different with a triangular shape that has a three-pipe design instead of the oval-enclosed four-pipe design on the current Aventador. It's also different from the exposed quad-pipe layout emerging from the SV's aggressive hindquarters. We're sure the different exhaust layout will alter the supercar's sound, but rest assured that the revamped Aventador can still spit a massive ball of flame. Rumors hint at the Aventador getting some additional power from its 6.5-liter V12 that currently generates 691 horsepower and 509 pound feet of torque. While the performance increase is up in the air, a dose of additional aggression will keep the Aventador looking fresh as it ages.

Lamborghini LB48H hypercar due next year: You might even say it glows

We know there's a hybrid Lamborghini Aventador successor coming sometime between 2020 and 2022. Due to deleted Instagram posts and a fissures in the rumor-verse, we expect a hypercar codenamed LB48H to preview the next electrified V12 Lamborghini. Autocar reports the next model in the Italian carmaker's series of low-volume specials will cost about $2.6 million, making it just another walk in the hypercar park as for price. The weird part is where Road & Track, referencing "a source familiar with Lamborghini's plans," says the LB48H will glow in the dark. The source didn't elaborate, so not even RT knows what that means. The Lamborghini Terzo Millennio concept from 2017 revealed a smattering of Tron-like light sculpture in its launch video. The wheels and engine bay glow, illuminated Italian flag graphics mark the front fenders, LED piping runs down the centerline. But lights don't come under the traditional definition of "glow in the dark." If the LB48H really does sport some kind of overall incandescence, well, we're about to enter a new chapter in hypercars. Other questions remain about how the LB48H will preview the future of Sant' Agata. The company's head of R&D has bemoaned the weight of batteries, admitting that the best-case scenario for the coming series-production hybrid V12 flagship means an additional 330 to 440 pounds. It's thought that the hypercar will use supercapacitors instead of batteries, providing a lightweight solution that would also showcase future technical potential. The all-electric Terzo Millennio employed nascent supercapacitor tech Lamborghini has been developing with MIT. That solution's upside is lighter size and weight compared to batteries, longer service life, a supercapacitor's fast charge and discharge ability, and the fact that it can discharge and recover energy at the same time. The downside is that supercapacitors have low energy density compared to lithium-ion batteries, so it's possible the LB48H could use a battery and a supercapacitor to work a 49-horsepower motor aiding an 789-hp V12. The production V12 is expected to get a more mundane solution. Lamborghini's looking ahead to cities mandating a minimum all-electric range up to 31 miles. One idea in play is a split hybrid layout, with an electric motor in charge of the front axle. That eliminates a prop shaft, and sharpens front axle response and torque vectoring.
