Lamborghini SC63 endurance race car unveiled for LMDh category

Lamborghini has set its sights on beating Porsche, BMW, and Cadillac, among other teams, in the top tier of endurance racing. The company has unveiled a race car named SC63 that was designed to compete in the LMDh category, and Autoblog sat down with CEO Stephan Winkelmann to get additional details about the upcoming model and its significance. Lamborghini has run a one-make racing series for over a decade, and its Huracan has competed in the GT3 category for several years, but the Italian brand has never been present on the highest echelon of the endurance racing world. Winkelmann explained why that changed. "This is a race series that's giving us a lot of visibility. We're not only racing in IMSA or in the WEC; we're racing in both. This is good for North America, it's good for Europe, and it's good for the Asia-Pacific region. It's a race series where the major OEMs are participating, so I think that also here there is an opportunity," Winkelmann told us. "We're a super-sportscar manufacturer; it's important." Power for the SC63 comes from a gasoline-electric hybrid powertrain built around a new, 3.8-liter twin-turbocharged V8 developed in-house specifically for the racing program. The system's total output checks in at about 670 horsepower, which is the maximum allowed by racing regulations, and the gearbox, the battery, as well as the motor-generator unit are standard components that other teams are using as well. That's not to say the SC63 is identical to, say, the BMW M Hybrid and the Porsche 963. Lamborghini explains that racing regulations give its engineering team the freedom to customize the gear ratios and the slip of the mechanical differential, among several other parameters.  Lamborghini asked a French firm named Ligier to develop and build the SC63's monocoque, though its engineers played a big role in dialing in the car's specifications. They notably requested a push rod-type front suspension system, ensured it has the ideal weight distribution, and made sure that critical parts are easy to access and service; every second count during a pit stop, even when you're competing in a 24-hour-long race. Lamborghini and Ligier also paid special attention to the brakes to find the right middle ground between weight and durability. Honing the SC63's aerodynamic profile was easier said than done, because LMDh regulations allow teams to use only one body kit per season, and the scope of the changes that can be made between races is limited.

Lamborghini announces twin-turbo V8 for LMDh racing

The car that replaces the Lamborghini Huracan is rumored to get a twin-turbocharged hybrid V8 possibly making something like 850 horsepower. The engine's origins and details remain in the shadows, but it's possible we'll get a preview of some of its components in Lamborghini's LMDh prototype racer. The Italian brand announced its entry for the Le Mans Hypercar (LMH) class of the FIA World Endurance Championship and the GTP class of the IMSA WeatherTech SportsCar Championship would be powered by a twin-turbo V8 developed in-house by the Squadra Corse motorsports division. All we know for now about the competition mill is that it will be a 90-degree V8 with an output of around 670 horsepower, midway between the 644 and 697 ponies allowed in the regulations. Partners in the enterprise include Bosch, which will develop the electric motor in the energy recovery system, Williams Advanced Engineering will supply power management software and the energy storage unit, while Xtrac will provide the seven-speed hybrid transmission. The engine will weigh at least 396 pounds, the minimum required by regulations, and enable a top speed of 210 miles per hour or thereabouts. This is the first time Squadra Corse has developed an engine for Lamborghini, and various race media have said it's not only different to the V10 used in Lamborghini's current Huracan GT3 and Super Trofeo cars, it's distinct from the twin-turbo 4.6-liter V8 going into the Porsche 963. The Huracan successor is thought to get an evolution of the 4.0-liter twin-turbo V8 in the Urus. However, it is impossible to believe Squadra Corse is expending the whopping amounts of time and money required for a race-winning engine for an internal-combustion powerplant that will only ever be used on track. The point of IMSA, the ACO, and the FIA coming together on mutual regulations for LMDh and LMH was to support road-applicable technology able to race in the premier sports car series' around the world. We should get our first look at Lamborghini's new race car by next year's Rolex 24 at Daytona at the latest. A year of testing in 2023 will lead to official competition outings in 2024, the teams running the car yet to be announced.  Related video: This content is hosted by a third party.

Lamborghini expands Huracan range with rear-wheel-drive convertible

The Lamborghini Huracan LP580-2 Spyder completes the game of fill-in-the-blanks in the Italian's automaker's V10-powered lineup. With the brand already having proved its customary formula of "Remove the roof, retain the awesome," we expect this to be another uncommonly pleasing convertible from Sant' Agata Bolognese. The three-layer roof and mechanism migrate from the all-wheel-drive spyder. Taking 17 seconds to lower, the bodywork springs various tricks to maintain the appropriate cabin atmosphere. Two fins emerge from the B-pillar to preserve the car's profile, with narrow ducts in those fins managing wind flow through the engine compartment. Keeping the rear window up also calms the cockpit, lowering it invites the breeze and the wail of the engine. Additional zephyr management measures come in the form of removable mesh windguards that can be fitted next to the headrests. View 26 Photos Minor adjustments to the front and rear are the only visible differences between the RWD coupe and Spyder. The 5.2-liter V10 rocks the same 572 horsepower and 398 pound-feet of torque and top speed holds steady at 198 mph, but the 0-60 mile-per-hour time creeps up by two tenths of a second to 3.6 seconds. Dry weight clocks in at 3,320 pounds, a 258-pound jump over the coupe, but 330 pounds less than the all-wheel-drive Huracan Spyder we sampled - and loved - earlier this year. Lamborghini says the Huracan rear-wheel-drive spyder price will slot in between the MSRP of the two- and four-wheel drive coupes when the car goes on sale in January 2017. Before then, you can view it for the much more reasonable price of "free" when it's unveiled at the LA Auto Show.
