Mercedes-Benz is set to run its 2014 turbocharged Formula 1 engine on a dyno test bed imminently, AUTOSPORT has learned, as technical chiefs played down concerns the new power units will not sound great.

With development of the new V6 engines pushing on, Mercedes-Benz sources have confirmed that the company's first version of its 2014 engine will be ready 'soon' - although a final date has not yet been sorted.

And with much interest about how these new engines will sound, amid concerns from Bernie Ecclestone and grand prix promoters that they will not be as loud as the current V8s, the man heading the design has no such worries.

Mercedes-Benz engineering director Andy Cowell said: "The engines are high revving. You don't get the maximum fuel flow rate until you are above 10,500rpm, and the maximum revs are at 15,000rpm. Plus, with six pipes going into one turbocharger, a single tail pipe from six cylinders revving at 15,000rpm I think will sound very nice."

The move to V6 turbos for 2014 has also prompted fears about a fresh spending war between manufacturers, but Mercedes-Benz is also confident now that strict technical regulations have kept costs under control.

This means that the idea of an engine-specific Resource Restriction Agreement has been dropped because it is no longer necessary.

Thomas Fuhr, managing director of Mercedes-Benz High Performance Engines, said: "The biggest achievement with this, irrespective of a physical RRA, was to get sensible technical regulations.

"The FIA, together with the manufacturers, did a great job. A lot of things are pre-defined, so you don't spend money developing it - you know there is a single turbo, so it makes things much, much easier. That is the biggest benefit out of these regulations.

"If you control it technically, it is much easier saying you can control it here and there. You see on the chassis front how complicated it has got. The FIA has it in hand with the engines, and there is no way you can go around this topic."


Be good if there was some video of this afterward, i really want to hear what it'll sound like...

Yes sir that is exciting news and I feel that Ferrari along with Renault are also testing but just being more secretive about it, 2014 cannot get here fast enough for me.

Probably posted already but here are the reg's again:

5.1 Engine specification :
5.1.1 Only 4-stroke engines with reciprocating pistons are permitted.
5.1.2 Engine cubic capacity must not exceed 1600cc.
5.1.3 Crankshaft rotational speed must not exceed 15000rpm.
5.1.4 Fuel mass flow must not exceed 100kg/h.
5.1.5 Below 10500rpm the fuel mass flow must not exceed Q (kg/h) = 0.009 N(rpm)+ 5.
5.1.6 Pressure charging may only be effected by the use of a sole single stage compressor linked to a sole single stage exhaust turbine by a common shaft parallel to the engine crankshaft and within 25mm of the car centre line. An electrical motor generator (MGUH) may be directly coupled to the same shaft.
5.1.7 All engines must have six cylinders arranged in a 90° “V” configuration and the normal section of each cylinder must be circular.
5.1.8 Engines must have two inlet and two exhaust valves per cylinder.
Only reciprocating poppet valves are permitted.
The sealing interface between the moving valve component and the stationary engine component must be circular.
5.1.9 Engine exhaust gases may only exit the cylinder head through outlets outboard of the cylinder bore centre line and not from within the “V” centre.
5.1.10 The crankshaft may only have three connecting rod bearing journals.
