Mercedes AMG Petronas has given Formula 1 fans around the globe a unique insight into the future on its official 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 has offered fans the first taste of what the new 2014 power units will sound like 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 F1 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 the sound of the new power units for 2014, with a maximum rev limit of 15 000 rpm and a single turbocharger spinning at speeds of up to 125 000 rpm. (Mercedes AMG F1)

Have we had any power figures yet

Bigger rear tyres will be an option since the new torques will be substantially higher than this season's figures..
Anyway I do not think the sound is that bad. Its something I can get used to. Its not the wet fart noise that I had anticipated on

Williams Mercedes, sounds strange but I have a lot more faith and belief in this relationship than with our previous German engine supplier.

Mercedes reveals sound of its 2014 V6 turbo Formula 1 engine

Mercedes-Benz has released the first audio of its new V6 turbo Formula 1 engine as preparations continue ahead of its race debut next year.

The lengthy clip, which is a full dyno lap of Monza that has been synchronised with video from Mercedes' simulator, provides the latest clue as to what the new generation of cars will sound like.



While the simulation gives the closest indication so far of the V6 turbo noise, Mercedes engine chief Andy Cowell has made it clear that it will be different when the real engines are running on track.

"Doing a recording in a test cell is quite challenging because you need to extract the exhaust fumes and extract them safely from the factory that the test cell is within," he said.

"An awful lot of technology goes into making sure these fumes are extracted and filtered, which naturally takes some of the sound with it.

"Then, a test cell is a room with flat walls, which causes the noise to bounce around and reduces the purity of the sound. It's an engine dyno - not a recording studio!"

While fans are intrigued about the sound of the new V6 turbos, Mercedes says its focus has been on trying to ensure its engine is as competitive as possible when the 2014 kicks off.

"We are a good way on and already heavily committed to tooling for long lead-time parts and working on iterations for installation purposes," said Cowell.

"When it comes to development, you have to run your own race. As ever with competitive people, they fight and strive to do as much as possible, focus on the issues that still have to be solved and rarely spend too much time reflecting on the successes."

WHY THE NEW ENGINES SOUND DIFFERENT

Mercedes-Benz engine chief Andy Cowell explains why the new V6 engines sound different to the current V8s:

"On the V8, you've got two tailpipes, so there are four cylinders feeding exhaust pulses into each tailpipe, the crankshaft is rotating at 18,000 rpm and there is no restriction in the exhaust system.

"We put a lot of effort into making sure it's a free-flowing exhaust system and highly tuned because the way to extract performance from a normally aspirated engine is to have highly tuned inlet and exhaust systems.

"On the V6, we have a single exhaust tailpipe, so all six cylinders are ultimately feeding into the single exhaust pipe.

"However, because the new formula for 2014 is focused on getting the most useful work out of a fixed quantity of fuel at a maximum flow rate, the regulations include the option to have a turbine in the exhaust system, which extracts energy from the exhaust flow to drive a compressor which boosts the inlet charge.

"The turbine also drives an MGU-H (Motor Generator Unit - Heat) for recovering excess energy over what is required for the compressor, which can then be stored in the battery and increase the boosting potential out of the corners.

"As soon as you have any restriction in the exhaust system, you reduce the volume of the noise because the turbine wheel is designed to recover energy from the exhaust flow, which naturally reduces the volume of the noise coming out.

"But because it's six cylinders firing into a single tailpipe, instead of four into each pipe on the current engines, the frequency will be very similar to the current 18,000 rpm.

"So we will have a similar frequency but lower volume because of the energy being recovered from the exhaust stream."

It sounds good... different. Not in a bad sense either. Just different.

Unfortunately the volume will be lower and that'll make a big difference I think. I never heard the V12s or V10s on track, only the V8s. And they are still mind bogglingly awesome simply because the sound is so overwhelmingly loud.

Hopefully these engines still give the fans plenty of auditive discomfort/ bliss.
