"An audio recording of Mercedes-Benz new turbo 1.6-litre V6 engine - driven this season by Messrs Hamilton and Rosberg - set against the simulated backdrop of the legendary Monza GP circuit, which you can listen to below.

It was recorded using a development engine at Mercedes AMG's High Performance Powertrains (HPP).

The capacity drops from 2.4-litres to 1.6, but also the rev limit is now just 15,000rpm (the current ones scream to around 18,000rpm), while the single turbo spins at speeds of up to 125,000rpm. Keen readers of the Internet will appreciate that this marks the return of turbocharged engines in F1 after many, many years; the last turbo era was in the 1980s.

So why now? Well, as mentioned, those regulations will change, setting engineers the challenge of completing 300km race distances on a 100kg fuel load. Mercedes tells us this requires a 30 per cent increase in energy efficiency. Along with the switch from free-breathing V8s to turbo'd 1.6 V6s then, is the introduction of more powerful energy recovery systems (ERS) - able to deploy ten times more energy that the current KERS setup.

The new ERS systems will recover energy from the exhaust turbine and the rear axle, and will be able to apply the recovered energy back to both.

Which is all fine, important business, but - and this is more important - does it sound good to you?"
