Tightening emissions regulations and fuel price hikes mean even supercar manufacturers are needing to tighten their belts in response.
The 2013 Lamborghini Aventador features a number of changes to the engine and chassis. Starting with the 6.5-litre V12, Lamborghini have added new cylinder deactivation system (CDS) and engine stop/start system. Six of the twelve cylinders are shut off when cruising at speeds of up to 135 km/h. Effectively running as an inline 6-cylinder engine, the CDS fires up the idle cylinders and restores all 515 kW and 690 Nm of torque within milliseconds, which Lamborghini says is virtually imperceptible to the driver. Most effective when travelling at a steady 130 km/h, the CDS delivers fuel consumption and emissions savings of up to 20 percent.
The engine stop/start system uses high-performance capacitors, or what Lamborghini term ‘Supercaps’, to restart the engine within 180 milliseconds after the driver moves to pull away. Lamborghini say the supercaps replace heavier conventional batteries and therefore the system is 3 kgs lighter than the current norm. Between these two new engine technologies, the 2013 Lamborghini Aventador is 7 percent more fuel efficient, but even so, average fuel consumption lies at 16 L/100km, while CO2 emissions have dropped from 398 g/km to 370g/km.
Other changes for the 2013 model year include revised suspension spring and damper rates for sharper response as well as ride comfort. A weight-saving carbon fibre pack is also available which includes a front spoiler, air intakes, engine cover, powertrain cladding and interior highlights. In addition, a new forged alloy wheel design, called ‘Dione’, is now available.
