SANT'AGATA BOLOGNESE, Italy – Lamborghini S.p.A. says its Murcielago supercar replacement will reduce carbon dioxide emissions 20 percent without sacrificing performance.
Next March, the Italian automaker will unveil the still-unnamed model at the Geneva auto show.
“The new model is part of Lamborghini's commitment to slash carbon dioxide emissions by 35 percent by 2015,” Lamborghini CEO Stephan Winkelmann said during a preview here on November 5. His comments and details of the event were embargoed until today.
As a small automaker that sells fewer than 10,000 supercars a year, Lamborghini was exempted from the European Union's requirement to slash carbon dioxide emissions to meet the EU's target to reduce average fleet emissions from Europe's new car fleet to 130 grams per kilometer by 2015.
But Winkelmann says Lamborghini, which is a unit of Volkswagen AG's Audi AG, can win over consumers by setting tough internal emission targets without sacrificing performance.
The new vehicle's 6.5-liter, 700-hp engine is more powerful than the current Murcielago's 640-hp powerplant. The new model emits only 398g/km of carbon dioxide, equivalent to about 17.2 liters of fuel per 100km or 15.6 U.S. mpg, down from the old version's 495g/km, equivalent to 22l/100km or 12.5 mpg.
The more efficient powertrain is mostly responsible for lower emissions, says Lamborghini Technical Director Giancarlo Reggiani.
He said the new powertrain accounts for 61g/km of the total 97g/km CO2 reduction in the new car.
Carbon fiber parts
To reduce emissions another 28g/km, Lamborghini used tires with lower rolling resistance and designed a more aerodynamic exterior. The final 8g/km CO2 reduction comes from using carbon fiber components to cut the vehicle's weight by 100kg (about 220 pounds) from the 1,750kg curb weight of the Murcielago, which has a steel spaceframe coupled with aluminum body panels.
