Formula 1 Switches to 1.6 liter 4 cylinder turbo motors

[Sticky]

This isn't a bad thing. Sure, we won't have the shrieking awesome sound of the motors any longer, especially with revs being forced down to 12k from 18+k, but power will be there. In the 80's BMW made 1800 something HP out of their turbo F1 motors. The number of engines to be used during a season by each team has dropped as well to 8.

We'll see what it's like:

[Payam@BMS]

thats gonna need some strong ass engine and i'm sure a bigg ass turbo will be fit to that. smart small little engine and higgh ass revs to pretty much take out a lot of the turbo lag. lots of power in t he powerband. would liek more details on this lol

Yet another step backward, they're going to sound like farts.

I would still have them using V10's but even F1 is cutting costs. Let's just be happy they haven't gone electric.

[M3_WC]

I don't really mind to the rule change.

What I do mind is the retarded "no refueling" rule. Kills all the action.

[fstop7]

I can understand the fear of fueling accidents after having a bunch of fires a couple of seasons ago, but it seems to me like the best solution would be to switch to a less dangerous method of refueling. Instead of using 1 zillion PSI high pressure systems, use gravity - like they do in other forms of racing.

Excellent!

Turbos are the future and having F1 resources to research how to get the most out of them will bring more power to my turbo powered BMWs in the next years and decades.

[black bnr32]

wha?

where did this come from and why? not knocking it, just downright curious!

[Sorena]

True drivers were 80's drivers ,1500HP,Manual and no ABS,ESP...

BTW i heard F1 cars are going to be limited to 650hp

[dzenno@PTF]

so f1 going FI is ok but bmw m cars isn't...man you contradict yourself

[DBFIU]

remember the 80s when F1 cars made 1500 HP from 1.5 liters.

Not at all, F1 already ran turbo motors. M said they would never run forced induction motors, huge difference.

[DavidV]

The no refueling rule wasn't done because of safety issues, it was done to make the races less tactical and more exiting to watch. Something thath has not worked at all.
Also the pointsysem was changed for this. This also did not work. If you recalculate the point to the pointsystem from last year, only place 4 nd five would be changed.
The turboengines of the 80s were extreme high power. This would, with nowadays techniques, give carspeeds that the circuits cannot safely accomodate. So the power must be restricted
Also, the turbo's of the 80s had a very short lifespan.
They would have an engine for the trainingssessions, a very beefed up engine for qualifying, and an engine that was supposed to last the entire race.
This will not be allowed for any more. In 2013 there will be 5 engines per driver for the entire season. In 2014 that number will be reduced to 4.

F1 ENGINE RULES FROM 2013
1.6-litre, four-cylinder turbos with energy recovery and fuel restrictions to replace current 2.4-litre normally aspirated V8s
Fuel efficiency to increase by a target of 50%
Overall power to remain same at approx 750bhp
Checks and balances to ensure costs are contained and performance across all engines remains comparable
Plan for advanced 'compound' turbos to be introduced in subsequent years
Power of Kers energy recovery systems to increase from 60kw in 2011 to 120kw in 2013
It is understood that a series of checks and balances have been written into the regulations to keep costs down and to ensure it should be impossible for one manufacturer to steal a march on the others in terms of performance.

[Sticky]

But they are capping the power potential of the motors? If so, that sucks.

[DavidV]

The new generation engines will be 1.6 litre high pressure gasoline injection units, revving to a maximum of 12,000rpm.
According to the FIA, the engines will deliver a 35% reduction in fuel consumption, while energy recovery systems will see 2010 performance levels remain.
So, KERS is back.

The year’s final World Motor Sport Council meeting in Monaco has seen Formula One’s 2013 engine formula given the official green light.
The meeting also saw several changes to the 2011 sporting and technical regulations.
Following controversies this season, the article forbidding team orders has been deleted, while the regulations regarding bodywork deflection tests have been redefined.
The concept of introducing movable rear wings in order to increase overtaking has also been approved.
Other noticeable changes are that gearboxes must now last five races instead of four, intermediate tyres are to be reintroduced, and the Race Director now has the power to close the pit lane during a race for safety reasons.
From 2012, team communications will be made available to broadcasters, a limit on suspension uprights will apply, and fuel compounds produced from biomass will be permitted.

The FIA has always done this, with every engine since the turbo time in the 80's.
They saw that if they didn't do this the powerlevels will get out of hand quickly. The circuits where the F1 races are held can not be made safe for such high speeds, and nobody wants any more dead F1 drivers any more. It is bad for the sport.

With the NA motors they capped power? I don't remember that, I think there might have been restrictions on revs.

[DavidV]

Rev restrictions and air intake restrictions pretty much limit the power you can get from a NA engine.
You really need the O2 to get the power. Fuel alone can only get you so far. That's why we have turbos

[Ryan Mills]

Hopfully all of this technology will trickle down to the consumer, so we all can have powerful and efficient 4 cylinders in the future. -Now only if they can make them sound decent. I do admit though, my GTI with the APR RSC exhaust sounded pretty nice -not like my 335 though....

[DavidV]

By limiting the revs to 19000 and later to 18000, and the engine to 2.4 liters, they control the amount of O2 to the engine.
It's 18000x0.5 (4-stroke) x 2.4l x 20.9% (O2 in air)=4514.4 liters O2 a minut at full throttle. Thats what they have to work with.

That doesnt take into account the technological breakthroughs the F1 teams got just by experimenting with new ways to increase volumetric efficiency. Revs and displacement alone will not restrict power. Nice try though

That is what I was going to say, more to it, cams, heads, intake, etc., which gave teams wiggle room to show engineering skill.

An hp cap sucks

[Sorena]

^ if FIA didn't limit teams budgets we would see both more power and efficeny
in this season the engines were limited to 18,000 ,and these engines had to be more durability since only 8 engines were allowed to use over the season ,they were less powerfull than last year's engines.

[fundahl]

I always liked the sound of high-strung, force-fed 4-bangers. They definitely don't sound like farts, or you must have some crazy digestion problems!

Advancements in compound turbocharging on gas engines would be cool. Boost Logic has one for the 2JZ and it flows 800HP worth of air with spool like a 300HP setup. (stock like or better)

You have a dyno to show to back that up? I would really like to see something like that. If turbo technology has come that far that is incredible.
