Lamborghini Asterion LPI 910-4 is silent but deadly [w/video]

The weirdest thing happened last night. During the annual Volkswagen Group Night festivities, everyone waited in anticipation for the Lamborghini section of the press conference. It's usually a treat for the senses - cool to look at, backed up by a ferocious sound that bellows throughout the venue. But not this time. There was no music, there were no laser lights, and most remarkably, there was no sound. The Lamborghini Asterion LPI 910-4 drove onto stage under fully silent electric power. Audibly, at least, it was perhaps the most anti-climactic Lambo introduction we've ever witnessed.
And that's the big story with this new Lamborghini concept: it's a plug-in hybrid. Of course, it's still a product of the storied Italian supercar maker, so that electric powertrain is mated to a 5.2-liter V10, and total system output is rated at a staggering 910 horsepower. It'll run up to 31 miles on pure electric power at speeds of up to 78 miles per hour, and its 0-62 time is estimated to be three seconds flat. Top speed? 199 mph. In other words, it may be capable of silence, but it still carries a stick, and it's still very much a Lambo.
So will the company actually build something like this? Right now, it doesn't look likely. Back in August at the Pebble Beach Concours d'Elegance, Autoblog spoke with Lamborghini boss Stephan Winkelmann about the then-off-the-record Asterion concept, who told us that if the automaker should choose to expand its model range, the bigger priority right now would be the Urus crossover. This is merely just a way to show how Lamborghini might present a gasoline-electric vehicle. And after scoping it out in person here at the Paris Motor Show, we have to say, it's cool. The styling is a bit softer and understated compared to the audacious Aventador or angular Huracán. But it still has quite a presence and it's still very much a Raging Bull.

Lamborghini close to joining premier LMDh class in IMSA

According to Racer magazine, Lamborghini hasn't officially said yes to joining the LMDh class in global endurance racing, but folks behind the scenes have green-lit the project and an announcement could come next month. Publicly, the brand's head of motorsport for the U.S. said work on a factory endurance program is "90% of the way there," the remainder to be sorted out by finding the right customer teams to lead the charge. Assuming this is what happens, Lamborghini will join Volkswagen Group siblings Audi and Porsche in the class, plus Acura and BMW. Cadillac hasn't made its intentions public, but observers expect the American luxury brand to come clean during this month's 24 Hours of Le Mans and show its LMDh challenger. Hyundai's apparently on the sidelines and leaning in, too. If all are counted, this would give the premier class for the IMSA WeatherTech SportsCar Championship seven entries come 2024, and potentially add to the top-class LMH field in the FIA World Endurance Championship . As a refresher, there are two top-tier classes coming to global endurance racing. There's Le Mans Daytona hybrid (LMDh) that begins in IMSA next year, and Le Mans Hypercar (LMH) that started competing in the WEC on May 1 this year. LMDh cars use a spec chassis provided by one of four suppliers, Dallara, Ligier, Multimatic, or Oreca. LMDh teams can use any engine and electronics they want, but they will all fit a spec hybrid unit supplied by Bosch, a spec lithium-ion battery from Williams Engineering and a spec gearbox from Xtrac. Max horsepower will be limited to about 680. Audi and Porsche opted for a Multimatic chassis powered by a turbocharged V8, and Lamborghini is expected to follow its family members. Every team can create its own bodywork, the limit being a 4:1 ratio of drag to downforce and a single aero package for the year to keep costs down. The LMH class is based on roadgoing hypercars, a manufacturer required to sell 20 of the retail hypercars over a two-year period to qualify. Although output's capped to around 680 hp as with LMDh, manufacturers can develop their own engines, gearboxes and hybrid systems. Discrete bodywork is allowed with the same drag-to-downforce ratio limit. There will be balance-of-performance restrictions imposed on LMDh and LMH fields, and measures such as torque meters mounted on driveshafts to monitor overall output of each powertrain.

Lamborghini Aventador successor to use supercapacitors instead of batteries?

While we continue trying to zero in on the next-generation Lamborghini flagship and its specs, Lamborghini CTO Maurizio Reggiani spoke to Road & Track to offer glimpses and set a few things straight. Discussing the coming LB48H supercar, Reggiani said the use of supercapacitors in that limited-run supercar will be a "first jump" into a robust hybrid application for supercapacitors, and that Lamborghini "will prove that in a super sports car, it's possible to have this technology." We've known the LB48H would use supercapacitors, but we didn't — and frankly still don't — know how. Based on Reggiani's comment, and likely the fact that Lamborghini uses a special supercar to hint at what's coming in tech and design, RT takes Reggiani's comments to mean that the Aventador successor will "store its electric power electrostatically instead of electrochemically, as you would with a lithium-ion battery." A caveat to this comes in another of Reggiani's remarks. He said the brand hasn't given any indication when an Aventador successor will reach the market, and before that happens, the brand is deciding whether to do another special edition flagship. "There's the possibility to have a kind of final Aventador family member," he said, because the brand probably won't get another chance to make a non-hybrid V12 after the scissor doors come down on the Aventador. Sales of the 6.5-liter V12 monster are still on the rise, remember. The current Aventador already uses a supercapacitor for the starter battery, to run the stop-start system. And the Italian carmaker has been working with MIT for years on such technology previewed in the Terzo Millennio concept, and rolled out for prime time in the LB48H. It's hard to see supercapacitors alone serving the next flagship, though, because company CEO Stefano Domenicali has said that "we need to respect legislation. In certain places, you will need electrification to go into the city." Supercapacitors can boost the kind of fast-acting peak performance buyers expect of a V12 Lamborghini. But their specific energy is roughly one-tenth that of a lithium-ion battery, or less; to provide the kind of range needed for all-electric trips into a city, the flagship would need a trailer hitch to haul a Urus carrying the supercapacitor array. Lamborghini has already said the best-case scenario for the Aventador successor is a 330- to 440-pound weight gain because of the hybrid system.
