Lamborghini Sesto Elemento - Страница 4

Carbon fiber even in the suspension

The 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:
Forged Composite: Here, materials with short carbon fibers are hot pressed in a mould. The process facilitates complex structures and is used for parts such as the underside of the monocoque and the suspension arms. Prepreg: The carbon-fiber mats are soaked in a thermoset liquid resin. They are pressed in moulds and cured in an oven under heat and pressure. Prepreg components have a very good surface finish and are therefore the preferred choice for use in visible areas. Braiding: This is a method to manufacture composite filament derived from the textile industry. Each thread is diagonally intertwined on different levels.

Drive: Concentrated power and amazing sound

The 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 drive

The 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.
Every single kilometer in the Sesto Elemento is sheer fascination – due in part to the relentless traction delivered under practically all conditions. This is largely attributable to the permanent all-wheel drive system. It incorporates a central viscous coupling and a self-locking differential for the rear wheels with 45 percent lock. Thanks to this superior traction, Lamborghini drivers can accelerate earlier out of a curve than those in rearwheel drive cars.
