Carbon fiber even in the suspensionThe suspension and the area around the engine have also been optimized with lightweight engineering. Alongside aluminum components, there are also carbon-fiber control arms: innovative Forged Composite technology is also well-suited to this kind of high-load part. These components are around 30 percent lighter than comparable aluminum parts. The propeller shaft is also made of CFRP by using Wrapping technology. This solution allowed the Lamborghini engineers to get rid of the central joint, bringing an important weight saving. The rims are also made from CFRP, while the brake discs are from carbon-ceramic composite material. A similar composite material is used for the tailpipes on the exhaust system – the compound of ceramic powder and synthetic resin makes this carbon material extremely heat resistant. A large number of screw fastenings feature a special titanium alloy and joining technology from the aviation sector. Based on the form, function and operational demands of the individual Sesto Elemento components, engineers from Lamborghini’s R&D selected largely from three CFRP manufacturing techniques within their technology tool kit:
Drive: Concentrated power and amazing soundThe fascinating heart of the Lamborghini Sesto Elemento is familiar from the Gallardo LP 570-4 Superleggera. In the Sesto Elemento too, the V10 unit is mounted “longitudinale posteriore” – longitudinally behind the driver. The 570 hp output equals 419 kW, all of which is available at 8,000 r/min. The pulling power is just as impressive – with the torque curve peaking at 540 Nm and 6,500 r/min. The V10 offers 5,204 cm³ of displacement, delivering a specific output of 80.5 kW (109.6 hp) per liter of displacement. The highlights of this longstroke engine with an aluminum crankcase include dry sump lubrication and a cylinder angle of 90 degrees. Both solutions are an integral part of the lightweight engineering approach, as well as serving to lower the center of gravity and thus tighten the handling characteristics. Ideal combustion chamber fill comes courtesy of a switch-over induction system and continually variable, chain-driven camshafts.
Best traction with all-wheel driveThe Sesto Elemento is equipped with the e.gear transmission, controlled in race car fashion via shift paddles mounted on the steering wheel. The automated system with electronic management shifts smoothly through its six gears much faster than a human being would be able to. |
