For spectators, though, the concern over the new turbocharged mills isn't so much one of power. We know the things will still be ridiculously powerful. What we're worried about is just what these new engines will sound like, which is arguably the most defining characteristic of any era of F1. Changes in cylinder counts and the addition of forced induction can result in dramatically different exhaust notes.
We've now gotten our first chance to hear the new engine that will be fielded by Mercedes AMG Petronoas and Williams next year. The engine used in the video below is a development powerplant at AMG's High Performance Powertrains facility in the UK. Set to debut for the 2014 season, it sounds, um, different? Now we know why Bernie Ecclestone mentioned augmented sound. It's certainly a big departure from the current V8s. Take a listen as it laps a virtual Monza circuit below, and let us know what you think of the new sound in Comments.
MERCEDES AMG PETRONAS lets 2014 engine roar on YouTube
The MERCEDES AMG PETRONAS Formula One™ Team has given Formula One fans around the globe a unique insight into the future today on its official commercial YouTube channel.
To mark the team's new status as a YouTube partner for the creation and broadcast of exclusive video content about the Silver Arrows team, MERCEDES AMG PETRONAS has offered fans the first taste of how the new 2014 Power Units will sound out on track.
The audio recording of the turbocharged V6 unit was conducted using a development engine at Mercedes AMG High Performance Powertrains (HPP) in Brixworth, UK.
This simulated lap of the Monza circuit – the definitive test of any Formula One powerplant – was then synced to a lap of the circuit at the team's Driver-in-the-Loop simulator at team HQ in Brackley, UK.
The result is the most accurate impression so far of how the new Power Units will sound in 2014, with a maximum rev limit of 15,000 rpm and a single turbocharger spinning at speeds of up to 125,000 rpm.
