2014 1.6T V6 15k rpm limited engines

 

Looks like the new F1 spec will allow plenty enough power to allow similar lap times to this year 2.4 V8 18k Natually aspirated engine and they do not sound to bad either.

The engine might have enough power, but how fuel efficient will it be? Next years maximum fuel load will be 100kgs, there is no max at present, but teams run about 160kgs.

I gather the Red Bull tank is about 150 litres.

 

The Specific Gravity of vehicle petrol is around 0.74.

 

This would give a weight of around 111 Kgs on the Red Bull trim.

 

The new engines are reckoned to be about 20% more fuel efficient than the 2.4 litre NA engines so the race should have no bigger a problem than currently even with 160 litre tanks with 118 Kgs of fuel with the better fuel efficiency.

 

Also I gather there is almost twice the energy recovery system allowable ie 150 hp.

Next year will be brilliant but I'm guessing a few will have problems, maybe even a few retirements. Bet there will be plenty of morons screaming for the engines to be banned once their favourite driver doesn't finish.

As well as the 15k RPM limit fuel flow rate is also limited. Not sure if this is enough to reach the 15k RPM.

 

Going to be interesting next year to see who wins and loses.

The weight of the powertrain on next years cars is higher, so the minimum weight of the car goes up from 642 kg to 690 kg.  Less fuel to lug more weight around the track.

Also a change in the exhaust design so it can't be used for aerodynamic advantage.

The regen systems, that harvest the vehicle braking and the turbo (somehow) and presumably the duble sized batteries must add quite a few kilos.

 

But clearly they are expecting these hybrid systems to account for much more of the acceleration instead of petrol.  Give it a few years a they might claim perpetual motion.   

The new ERS system which replaces KERS is supposed to give 160 bph for 33 seconds in a lap as opposed to KERS giving 80 bhp for 6 seconds.

I still think there will be races where the driver has to slow down in the last part of the race to save fuel. Otherwise they will be praying for X amount of laps with the safety car.

It also seems that cooling the car is going to be a challenge for the designers.

Of course fuel saving will still occur. Less fuel = Less weight = faster car. F1 logic for you, drive slower for now so we can drive faster later.

I have been told from an insider at red bull that they wont be on the pace next year and have put all their effort into this years car!

So that should be a welcomed relief

I think next year will be a real game changer with all the rule changes new engines to understand etc I wouldn't be surprised to see some midfield teams getting up near the top.

The engine manufacturers could play a bigger role. 

 

Though Ross Braun was reckoning that Chassis design is the most important thing and that may continue to be key.

 

Andrain Newey is arguably as repsonsible for 9 World Champion wins as the driver.  He is paid around $10M a year.

 

Renault do not have the most power but Red Bull far and away have the best aero package and chasis.

Putting on flame retardant suit before saying that I think it doesn't matter what changes they make to the regulations in terms of engine size, fuel limit etc, it will still be a procession.

Ban wings and driver aids and F1 might get interesting again.

Just my opinion and not intended to offend.

The only driver aids is power steering. DRS helps with overtaking but I don't think is needed and then there's KERS/ERS which is a great addition to F1. There's strategy to deploying it and with there being different manufacturers some may have more go than others. It should be pretty interesting.

Tank volume is relatively irrelevant, all fuel in F1 is measure in kilos to eliminate any miscalculation due to the volume altering according to temperature. The designers will always design in a tank to the smallest capacity possible and only put in as much as needed taking into account safety cars etc reducing fuel consumption. They will also push things too far so that at some time during the race the driver will have to go into fuel saving mode otherwise he won't get to the end. Reducing the allowable fuel to 100 kgs represents quite a technical challenge, there is no need for a flow rate limit as the teams only get the allowable fuel and it is up to them to use it in the most efficient way to get them to the end of the race.

P.S. Moley, like your saying at the bottom of your posts, I know what I like too!

Decent bit by Gary Anderson here about next year's power-trains http://www.bbc.co.uk/sport/0/formula1/25158104 - also touches a little bit on the other regulation changes.

Well, I've found one error anyway. GA states that this is the first time F1 has used direct injection engines. The Mercedes W196 used direct injection in 1954 and 55!

It's an interesting read although he's wrong about F1 leading the way as I would have thought he'd been familiar with the FIA WEC LMP1 hybrid cars which are a couple of years ahead of F1 with this technology.  They introduced hybrids last year with Audi fitting their e-tron Quattro with a secondary 200bhp electric engine powered by a flywheel charged up under braking which when activated drove the front wheels while the turbodiesel engine powered the rear.  Toyota went for a more powerful 300bhp electric engine powered by a supercapacitor system along with a petrol engine both driving the rear wheels to give either better fuel efficiency or performance.  What's particularly interesting when considering potential road use is that Toyota produced a Yaris concept car which used a 1.6 turbocharged petrol producing 300bhp and three 60bhp traction motors attached to a supercapacitor system.  The advantage of this over batteries is the ability to quickly charge and discharge so when using the brakes the Yaris would use the third traction motor to charge the supercapacitor then powering back out it could discharge through the other two traction motors to give the car 300bhp through the front wheels combined with 120bhp through the rear wheels.

 

Next year it's hopefully going to get more interesting with hybrid technology as the rules will allow them to harvest more power to feed bigger electric engines so they can reduce the petrol/diesel engine and improve overall efficiency.

 

What I find disappointing about the F1 and these new rules is that they're so rigid, when KERS was first introduced not all manufacturers used the technology as they found the additional boost wasn't worth the potential unreliability and weight issues.  When all cars have the same system it loses a lot of its impact as cars can boost to defend as much as a car is boosting to overtake.  Then again even with such rigid rules Red Bull have utterly dominated which has made for very dull racing so I guess having more varying rules would be difficult.  With this year being one of the dullest I can remember I really hope the new rules shake the order up a bit although without big changes to the aero system I'm not sure that's going to happen.

Four wheel drive is not allowed in F1, so those hybrid systems can't be used.

That is incorrect, Toyota's LMP1 system is rear wheel drive only as it's designed to be integral to the petrol engine so it cannot (and never has) driven the front wheels in the TS030.  Although Audi's system does drive the front wheels to give temporary four wheel drive, that is their choice as the system can be used for RWD only - the system Audi are using is designed and manufactured by Williams as it was originally intended for F1 cars.

In simple terms, this is the difference between 2013 and 2014 cars.

 

 

For more technical details see this article: http://www.f1technical.net/features/19037

Italian F1 site reporting rumours that the Renault engine's may not be ready for the first test in Jerez due to issues with the turbo. They suggest that Renault powered teams asked for the test to be postponed by a week, which of course was declined by the other teams.

 

Oh, and who makes these turbos? The company formerly known as KKK. Weak KKK turbos? Where have I heard that story before  ?

Interesting reading, even more so as googles Italian translation is rather literal.
