I’m still not entirely convinced that a dual-clutch gearbox won’t ultimately end up in a Lamborghini flagship - instead of the admittedly trick single-clutch unit shown at the powertrain preview at Sant’Agata a couple of weeks ago.

But there is something reassuring about the fact that the engine that will slot into the Murcielago’s successor is still a normally aspirated V12.Read the full story on Lambo's lightweight future

The 6.5-litre capacity is the same as the outgoing motor, but every component has changed for the new motor, codenamed L539. It has more power and a higher rev limit. It has more torque, the peak of which is produced further down the rev range. It is lighter. It can sit lower in the car. And yes, it’s cleaner too.

Lambo boss Stephan Winkelmann says the essence of “super-sports cars” is a normally aspirated motor, so turbocharging is not really on the agenda, even as the firm tries to cut its average CO2 emissions by 35 per cent by 2015.

“We have to look very carefully at what customers expect from us as a brand,” he told me. “That cannot be changed. If we alter that then we have nothing.”

I know what he means. At the presentation, Lambo wheeled out a promo video. You know the form: dramatic orchestral soundtrack, sweeping macro-zoom footage of the engine, footage of engineers scribbling notes on clipboards. It was, frankly, bordering on pretentious nonsense. I don’t even want to think how much cost to produce.

But for the last 30 seconds the music faded away, and all we could hear was the V12 on the test bed. On full song. Screaming. At 8250rpm. And even the most cynical observers admitted that the hairs on the back of their necks had stood up. Bring it on.
