Improving Sound, Cost Among Guidelines for 2021 Power Units
While focus remains on the last couple events of 2017, FIA is already working on planning the future of Formula 1, namely the power units. On Tuesday, the governing body laid out the guidelines in which are meant to “excite and engage” both teams and fans.
“We’ve carefully listened to what the fans think about the current PU and what they would like to see in the near future, with the objective to define a set of regulations which will provide a powertrain that is simpler, cheaper and noisier and will create the conditions to facilitate new manufacturers to enter Formula 1 as powertrain suppliers and to reach a more leveled field in the sport,” said Ross Brawn, F1’s MD, Motorsports. “The new F1 has the target to be the world’s leading global sports competition married to state of the art technology. To excite, engage, and awe fans of all ages but to do so in a sustainable manner. We believe that the future power unit will achieve this.”
The full details will be released by the end of this year, but teams are not allowed to begin design and development until the 2018 season concludes, therefore ensuring focus remains on current competition. Between now and then, the series expects to work with teams to great test and development restrictions, as well as other things in relation to keeping the cost down.
“The 2021 power unit is an example of the future way the FIA as regulators, F1 as commercial right holders, the teams and the manufacturers as stakeholders will work together for the common good of the sport,” continued Brawn.
Here are the features as released so far:
- 1.6 Litre, V6 Turbo Hybrid
- 3000rpm higher engine running speed range to improve the sound
- Prescriptive internal design parameters to restrict development costs and discourage extreme designs and running conditions
- Removal of the MGUH
- More powerful MGUK with focus on manual driver deployment in race together with option to save up energy over several laps to give a driver controlled tactical element to racing
- Single turbo with dimensional constraints and weight limits
- Standard energy store and control electronics
- High Level of external prescriptive design to give ‘Plug-And-Play’ engine/chassis/transmission swap capability
- Intention to investigate tighter fuel regulations and limits on number of fuels used
“Today was a key step in the development of the Power Unit regulations for 2021,” added Peter Bayer, FIA Secretary-General for Sport. “The FIA has been working with the Commercial Rights Holder to define a positive step forward for these regulations which maintain Formula One’s place at the pinnacle of motor sport technology whilst addressing the key issues facing the sport such as cost, road relevance and fan experience at the racetrack. We felt it was important to bring the teams into the discussions today and explain the direction we are taking and I’m pleased with the response we have received.”
