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.

This incredible life-size Lamborghini Aventador is made out of paper

We've all screwed around with the cutting and folding fun that results from paper model making over here at the Autoblog Craft Workshop (not a real thing), but we've yet to dive into a project with real scale. Thankfully, dedicated hobbyists the world over are taking care of the heavy lifting for us on this front.
Years back we brought you images of an Epson team mid-build with a full-scale Honda NSX racecar, and that project might still be the granddaddy of the genre (though this Audi A7 and this Bugatti Veyron are pretty good, too). But the Lamborghini Aventador police interceptor model seen here, measuring eight-feet long, is right up there. Gaming fans will recognize the Need For Speed inspiration for the wood pulp Lambo, and after watching the fast-motion video of the entire build process we should all be able to recognize the hard work that went into the car's completion.
Taras Lesko is the designer behind this mammoth paper project; you can read a bit of detail about what went into the build on his website, or you can scroll down to watch it for yourself.

Lamborghini Huracan Performante's active aero is the secret to its speed

The most revolutionary real technology at this year's Geneva Motor Show didn't look like it on the show stand. If you squint at the Lamborghini Huracan Performante, it merely looks like a Huracan with a big wing. Up close, you can see the fractal texture of the forged-composite aerodynamic add-ons, but that still doesn't tell you why this car is so special. Lamborghini calls it Aerodinamica Lamborghini Attiva (ALA), or active aerodynamics. This is one of the biggest keys to the Performante's claimed production-car record lap time at the Nurburgring Nordschleife of 6 minutes, 52.01 seconds. The Huracan Performante's number is not without controversy, but I personally care very little about the obsessive phallic-measuring contests that are 'Ring lap times. What's fascinating about the Performante is that, if the lap time is even close to legitimate, it shows that ALA is a major step forward in automotive performance. More than just lap times, the Huracan Performante is an example of why Lamborghini remains special in a world of democratized performance. We sat down to discuss this with Lamborghini's Research and Development Director, Maurizio Reggiani. And one last note on the lap time: Reggiani says with the same temperature and exclusive access to a dry track, "that in this average of speed we can repeat, repeat, repeat, repeat." In previous conversations, Reggiani said that the key difference in performance would come not from horsepower, but weight reduction. For Lamborghini, that means plenty of carbon fiber. But the newest Huracan is not a Superleggera, the old title for the hardcore variant. "Superleggera is too much an objective, a description. Performante is really the DNA of the car. In Italian, Performante means really the best performance," he said. Reggiani continues, "Nothing happened by chance. It's really a building-block approach where you say this can give this contribution, this can give that. Where can you improve something and what is needed to improve something?" That brought them to the active aerodynamics solution, which channels air to stall the front or rear aero elements of the car to change the downforce and drag. Reggiani says, "This can be achieved only with a system that is really light, [has] fast responsiveness. Based on this ...
