FIA to guard against “extreme engines” in 2014

2014 F1 rulesPosted on | Author Keith Collantine

Mercedes 2014 V6 F1 engineThe new engine regulations for 2014 have been designed to discourage teams from producing “extreme engines” and employing “exotic strategies”, according to the FIA.

F1’s governing body intends to make energy efficiency a priority for the teams in designing their new cars and engines and will limit each driver to using no more then 100kg of fuel per race next year.

But, as FIA head of powertrain Fabrice Lom explained to its magazine Auto, the rules go further than that to prevent teams coming up with unusual attempts to get around the rules:

“Giving the same amount of fuel to each car is an easy way of promoting efficiency – but the requirement is not as simple as that.” said Lom. “With no other limitations we might see some extreme and dangerous powerful engines, coupled with exotic strategies.”

“The fuel-flow limitation is there to stop this, enforcing a certain level of control. I say ‘a certain level’ because the engineers working on this project have an infinite amount of ingenuity, and over time the will certainly develop more efficient engines with greater power output.”

The current V8 engines are subject to a development freeze and a similar policy will be gradually introduced for the new engines to prevent development costs getting out of control (see below).

Renault energy F1, 2014 F1 engineRenault Sport F1 deputy managing director (technical) Bob White said: “A multi-year specification freeze is not really where we think the balance should be.”

“But equally, it shouldn’t be a development free-for-all that would make the necessary investment unaffordable. We’re heading towards year-on-year tightening restrictions and we think that’s a prudent and responsible approach.”

The FIA’s plan for freezing development of the engines calls for 8% of power unit components by weight to be frozen in development by 2015. That will rise to 23% in 2016, 35% in 2018 and 95% the year after that.

“The aim of the new regulations is to keep F1 at the pinnacle of motor sport,” added Lom, “but to do so mindful of the era in a which we operate.”

“Yesterday the sole aim of transportation was to travel from A to B as swiftly as possible. Today the technology is such that anyone can go fast – but they do so knowing resources are not unlimited and must be used with care.”

With the new V6 engines producing around 600bhp plus a further 150bhp coming from the Energy Recovery Systems, next year’s engines are expected to produce at least as much power as the current V8s.

But the higher minimum weight limit for cars should mean lap times remain similar. However FIA race director Charlie Whiting has previously suggested lap times could rise by two to three seconds next year.

  1. I see aq dream – I wish all the engine manufacturers to participate in the following progression – to build engines that blow the 100 kg of fuel say in about 50 km – then after a couple of races with all the grid stopping all over the track with empty fuel tanks after about 15-20 minutes of racing, there will be a hope that at last fans will see the freezing or ban of development restrictions and people imposing them who kill the sport and innovations.

  2. But I like “extreme engines” and “exotic strategies”…

  3. Seems sensible to me.

  4. Yes, that’s what I need:

    “The car was like a bomb at circuits like Spa, Austria and Monza. And the power was unbelievable – even if the turbo delay was terrible. You’d open the throttle at the entry to the corner only to get the power at the exit. And if you missed it by five or 10 metres, there was nothing you could do – you just spun it. The lag was about one or two seconds. At Zeltweg, down the long straight to the Bosch Kurve, the car was throwing out 1400 bhp and just kept on pushing – you felt like you were sitting on a rocket.” – Gerhard Berger speaking about the Benetton BMW B186

    That’s why I became F1 fan back then and now, when I see “exotic regulations” and “extreme restrictions” I think it’s time to find some other favourite sport – watching F1 drivers saving their Pirellis was more than enough yet, and when they start to save drips of fuel and install solar panels onto F1 cars, I quit…

  5. I understand the approach to be more efficient and “greener”, BUT F1 is and still should be the number one in motorsport. Unfortunately things are not going well, I personally don’t like the absence of refueling, those tyre compound regulations, DRS (the silliest of them all) and a few other things aswell. I mean GP2 racers are sometimes faster than a F1 car. How can it be? It can’t be right. F1 is exquisit, it should be the most exciting and the most fastest motorsport. This freezing idea is quite the opposite what F1 should be. As already other F1 fans posted, the ingenuity, incredible innovations and superb engines are the sorft of things F1 is made of. There are lots of examples which I could post, what should be changed, but no….. I am following F1 since 1998 and have missed maybe a handfull of them all, but since the RedBull domination started, and when regulations change so rapidly, it’s no longer fun watching F1 races. I would rather prefer the unlimited budget to develop cars and ged rid of a number of rules, because there are plenty of sponsors and investors who could make things happen for smaller teams. Maybe I have got off topic a bit, but I fear that F1 is about to become a boring Carrera Slot race.

  6. SaidLom, “With no other limitations we might see some extreme and dangerous powerful engines, coupled with exotic strategies.” That is exactly what F1 fans want to see, some ingenuity. Thanks for not giving us fans what we desire from Formula 1. What a joke.

  7. I hope the ratings and attendance figures drop precipitously in the next few years and these dumb asses finally come to their senses and realize they have ruined what was once the best show on earth.
