F1 hope fuel rule change will make flat-out racing possible, reveal glimpse of 2021 regs

Liberty Media hope that an increased fuel allowance on Formula 1, to be introduced next season, will allow drivers to race flat-out for the entirety of races. The move is the first of an anticipated raft of tweaks in an attempt to boost overtaking.

The need to save fuel is often cited as a reason that drivers do not drive to the limit throughout grands prix, although overtaking has also been made more difficult by the aerodynamic regulations introduced in 2017.

Changes to the aerodynamic systems in cars remain a topic of discussion, with proposals over changes likely to be formed by the end of the month, according to an F1 statement.

F1 confirmed the following will be implemented in 2019:

- An increase in race fuel allowance from 105 to 110 kg. This will allow drivers to use the engine at full power at all times.

- Driver weight will now be considered separately to the car, meaning heavier drivers will no longer be disadvantaged.

- Drivers will be required to wear biometric gloves to increase safety and facilitate medical rescue.

F1's statement also revealed the first pieces of information regarding new engine regulations proposed for 2021 and beyond.

Ferrari have been particularly vocal critics of the planned changes, with CEO Sergio Marchionne routinely threatening to pull the Scuderia out of F1.

The statement added: "Looking further ahead, the FIA presented its proposals for the 2021 power unit regulations, under which teams would continue to use 1.6 litre, V6 turbo hybrid engines, but with the MGU-H exhaust energy recovery system – one of the current unit’s most complex and costly elements – removed.

"The FIA Technical Department will now meet with current and potential power unit manufacturers to discuss the proposals in more detail, with a view to finalising the 2021 regulations by the end of May."

Supercar manufacturer Aston Martin have suggested they could move into F1 when the new engine regulations are introduced.
