2013 Lamborghini Aventador gets cylinder deactivation and innovative start/stop systems

Article by Christian Andrei, on October 1, 2012

The Lamborghini Aventador LP 700-4 has increased its lead over other sports cars with its ground-breaking technologies. These include cylinder deactivation when there is partial load resulting in significant savings in terms of fuel consumption and the new and very fast stop-star system with the supercaps to store energy. The 2013 Aventador also comes with a multitude of individualization options.

Automobili Lamborghini used a highly advanced and distinctly unique technology for the 2013 Aventador’s stop-start system. Suppose the car is at a stop phase like when it’s at a traffic light, the energy needed for re-start is delivered through its supercaps which are high-performance capacitors.

These allow fast start-up, giving the V12 engine full power in merely 180 milliseconds, faster than many of the current conventional systems. In the tradition of the Lamborghini’s philosophy of lightweight design, the new technology ensures a weight reduction of 3 kilograms. Its battery supplies power solely to the electronic systems occupying little space and it can last through the entire lifetime of the vehicle.

The second technology utilized by the 2013 Aventador is called the Cylinder Deactivation System or CDS. When there is low load and the car is travelling below 135 km/h, one cylinder bank is deactivated by the CDS enabling the power unit to run as a typical inline six.

However with just a small change in the gas pedal, the 700 horsepower V12 engine is brought back online. Since both the stop-start system and the CDS work fairly quickly, it is indiscernible to the driver thus resulting in no negative impact on what is already an amazing driving experience.

What is noticeable however is the benefit when it comes to efficiency. The average fuel consumption of the 2013 Aventador is reduced by 7% to about 16 liters per 100 km. At road speeds of 130 km/h, the reduction in the emissions and fuel consumption can go down to about 20%.

This has resulted in the CO2 emissions of the 2013 Aventador being reduced to 370 g/km from 398 g/km. Lamborghini also refined further the chassis setup of the 2013 Aventador. The already razor-sharp handling has been made even more precise and through optimized dampers and stiffer springs, the ride comfort has been improved as well. Also made available are the new alloy wheels with the Dione design.

Carbon fiber, a very lightweight material, is also featured extensively as part of the 2013 Aventador. A large portion of the technological superiority of the 2013 Aventador is due to the CFRP monocoque.

This material has elevated the model’s profile with a package of different CFRP components like the air intakes, engine cover panel, front spoiler, and powertrain cladding. The CFRP’s interior applications are complementary to the unique design of the 2013 Aventador.

News for the Lamborghini Aventador LP 700-4: More efficiency with cylinder deactivation and innovative stop-start system

The Lamborghini Aventador LP 700-4 is extending its leading position among super sports cars with groundbreaking technologies – an innovative and extremely fast stop-start system with supercaps for energy storage and cylinder deactivation under partial load bring significant savings in fuel consumption. Plus, the 2013 Aventador comes with a host of new individualization options.

Automobili Lamborghini is using a highly advanced and utterly unique technology for its new stop-start system in the Aventador. The energy for re- start following a stop phase (e.g. at a traffic light) is delivered by high- performance capacitors known as supercaps. They enable extremely fast start-up – full V12 power is available again in a barely detectable 180 milliseconds, significantly faster than with conventional systems. And, in keeping with Lamborghini's lightweight design philosophy, this new technology also delivers a weight saving of three kilograms. The classic vehicle battery supplies only the electronic systems, occupies very little space and lasts virtually the entire vehicle life.

The second new efficiency technology is the Cylinder Deactivation System (CDS). Under low load and at speeds of less than 135 km/h, the CDS deactivates one cylinder bank, allowing the power unit to run as an inline six. But with just the slightest movement of the gas pedal, the extreme performance of the V12 engine with its 515 kW/700 hp is back online. The CDS and the stop-start system work incredibly quickly, are virtually imperceptible to the driver and have absolutely no negative impact on the amazing driving experience. Yet, they deliver a noticeable benefit in efficiency – the average fuel consumption of the Aventador LP 700-4 drops by seven percent to 16 liters/100km. At highway speeds of around 130 km/h the reduction in consumption and emissions is as much as 20 percent. In total the CO2 emissions of the Aventador have been reduced from 398 g/km to 370 g/km.

The Aventador's chassis setup has also been further refined. The razor-sharp handling is now even more precise, while ride comfort has been noticeably improved with stiffer springs and optimized dampers. New forged alloy wheels in the Dione design are now also available.

Carbon fiber is a lightweight material that features extensively in the Aventador. A substantial proportion of the super sports car's technological superiority is thanks to its CFRP monocoque. This material now takes on an even higher profile with a package of optional CFRP components – front spoiler, air intakes, engine cover panel, powertrain cladding and interior applications in CFRP set accents in the Aventador's unique design.
