2014-2020 Formula One 1.6l V6 turbo engine formula

[PlatinumZealot]

Turbine now has one entry.

[PlatinumZealot]

The new Renault engine is reported to have 5% more horsepower across the whole rpm range and the MGUH now has 25% more power too.

Turbine looks bigger, and so does the compressor. The engine mount looks to be hollow for fluid passage.

The turbine housing might look bigger but the turbine might be just the same, no way to tell without seeing it. You could be right though.

The volute will look bigger if the have gone from twin to single entry, the turbine wheel may be exactly the same size.

Two things of not to me from that picture. firstly I'm surprised they have gone for a single entry turbine, efficiency will improve but packaging will suffer and twin entry seems to have been the de rigour. Secondly you can see that Renault are casting the crankcase whereas Merc are machining from solid, I suspect this will reduce weight and possibly improve cooling efficiency but does limit their ability to change and adapt as casting has a long lead time.

[PlatinumZealot]

Merc's is casted too.. its the cover plates are machined.
Billet Machined block would be too heavy. and you will never get the detailed channels you want.

[gruntguru]

Anything cast is likely to be post-machined wherever possible to reduce weight and increase accuracy.

All are talking about more power, but it is drivability of the engine and power deliverance that makes the difference. Response, tourqe and how the engine is responding is the solution. Not outright top end power... Ferrari suffered from this the whole last season with poor drivability and a too steep power curve.

25% more power for what? It only uses 'power' to maintain turbine/compressor speed so are they saying that the turbo unit requires 25% more power or that the MGUH can harvest 25% more energy from the exhaust.

For argument' sake, say, if they were able to harvest 60kW from the MGUH in 2014, This year they would be getting 75KW.

Facts only has called me out on this one...

People...

I stand corrected!

We are doing some research to verify....

Is 2015 Ferrari engine as (almost?) good as 2015 Mercedes engine over one lap?

Here are some interesting top speed averages of difirent engines from qualy in Australia, data is from here

• Mercedes=325,6km/h

• Ferrari=325,3km/h

• Renault=317,1km/h

• Honda=312,6km/h

I used averages becouse it should even out difirent car carakteristics a bit. What do you guys think?

From Forix.com - official speed trap figures

Cla Nº Driver Km/h
1 77 Valtteri Bottas 329.0
2 19 Felipe Massa 327.6
3 5 Sebastian Vettel 327.6
4 13 Pastor Maldonado 327.5
5 11 Sergio Pérez 325.5
6 7 Kimi Räikkönen 325.3
7 8 Romain Grosjean 325.1
8 9 Marcus Ericsson 324.7
9 27 Nico Hülkenberg 324.2
10 12 Felipe Nasr 323.8
11 6 Nico Rosberg 323.1
12 44 Lewis Hamilton 323.0
13 26 Daniil Kvyat 319.1
14 3 Daniel Ricciardo 318.8
15 55 Carlos Sainz Jr. 315.9
16 33 Max Verstappen 314.7
17 22 Jenson Button 312.8
18 20 Kevin Magnussen 312.5

I would think that suggests the Ferrari is in the ball-park for peak power, but does not tell much about other operating points.

[PlatinumZealot]

Well considering that a renault set the fastest speed last season, top speed isn't enough data to say which engine is the most powerful. So much factors like drag (see Mercedes VS Williams speed trap, vehicle traction, and effectiveness of DRS) affect the top speed. with that said I'm not really sure what conditions one can get a good reading off of.

[bill shoe]

I saw a good engine-power analysis a few years ago where they analyzed accel at medium speed, so the cars were not traction-limited like low speed, and they were not drag-limited like high speed. So maybe accel from 100-140 mph during qualifying when everyone is running max power and equal (low) fuel loads. This seems like a good approach, and the teams have all the GPS data on each other in this regard. Unfortunately, the FIA dumbs down this info for the public and I don't know if it's available to the general fan.

Actually, at the moment I can't even find the top-speed trap info on the lovely redesigned Formula1.com website.
