Lamborghini Unveils Its New Range-Topping Powertrain

We may not know all there is to know about the upcoming Jota quite yet. In fact, we don't even know if it will be called the Jota any more. But we now have the full details on what will power Lamborghini's next halo. The company has revealed its new V12 powertrain.

While Lamborghini intends to go lighter and to focus more on specs, like acceleration and weight than top speed and power, the company is not planning on abandoning its big V12s altogether. It said that such a step would mean altering Lamborghini's DNA, something that they're going to resist as much as possible.

CEO Stephan Winkelmann told Autocar: "We must fight to preserve that DNA and that will influence what we do to improve the CO2 emissions. Performance is still at our core. If we alter that then we have nothing."

What Lamborghini has done is cut emissions of its new V12 powertrain by an estimated 20 percent in an effort to keep pace with tightening restrictions. It plans to cut emissions by 35 percent across its line by 2015.

While the new powertrain is cleaner, it's also more powerful. Displacement remains at 6.5 liters, but the engine puts out 691 hp and 509 lb-ft of torque. It uses a larger bore and shorter stroke. The engine is about 40 lbs. lighter than the outgoing V12 and gains efficiency-boosting features like switchable water circuits that quicken warm-up and eight scavenging pumps to reduce pressure and scavenging losses by 50 percent.

Lamborghini will pair the engine with a new single-clutch, seven-speed automated manual transmission that it describes as "a sequential race gearbox in a roadgoing car". Three gearbox modes will be available to drivers: Strada, a fully automatic mode; Sport and Corsa, which will include launch control. Four shifting rods help to keep shift times down to just 50 milliseconds, which is about 40 percent quicker than on the Gallardo Superleggera's e-gear transmission.

Lamborghini will not offer a manual transmission option on its next flagship.

Rumors indicate that the next Lamborghini, whether it be called the Jota or Aventador, will also use lighter construction to boost efficiency. It's expected to lose around 500 lbs. over the retired Murcielago. Performance estimations put the car to 62 mph in under three seconds and onward to over 217 mph.
