F1 makes changes to address new engine rules concerns

F1 CorrespondentPublished5 hours ago681 CommentsFormula 1 has made a series of rule changes to address concerns about the new engine regulations that were introduced for this season.

The amount of energy management required with the new power-units, which have a near 50-50 split between internal combustion and electrical power, has led to complaints from the drivers that their skills were being diminished.

Four-time world champion Max Verstappen has gone as far as to say that he is considering his future in F1 as a result of his dissatisfaction with the new cars.

The changes amout to a swathe of modifications to the way the engines operate aimed at allowing drivers to push to the limit in qualifying and reduce the risk of large speed differentials in races.

These arise when one driver is deploying the full power of their engine and battery and another has no electrical charge - a difference of 470bhp.

They are split into a number of different areas, and most will be introduced at the next race, the Miami Grand Prix on 1-3 May.

F1 bosses to use 'scalpel rather than baseball bat'

Published1 day agoMercedes F1 boss Toto Wolff had previously on Monday described the changes as "acting with a scalpel and not with a baseball bat".

Wolff added: "We all share the same objectives. It's how can we improve the product, make it out-and-out racing, and look at what can improve in terms of safety."

The changes were approved at a meeting of the F1 Commission of team bosses, F1 and governing body the FIA on Monday, following a series of meetings between technical chiefs, and between the drivers and the FIA. They must be rubber-stamped by a meeting of F1's legislative body, the FIA world council.

The changes in qualifying are, according to a statement from the FIA, "aimed at reducing excessive harvesting and encouraging more consistent flat-out driving".

Drivers were being forced to lift and coast - lift off the accelerator for a few seconds before braking for a corner - in some instances on a qualifying lap, one of several examples of new practices drivers have labelled "counter-intuitive".

The total amount of permitted recharge on a lap has been reduced from 8MJ to 7MJ - thereby reducing the amount of energy needed to be recovered and therefore the amount of time doing so.

In addition, the maximum amount of power recovered when the driver is on full throttle but not deploying the battery - known in F1 terminology as "super-clipping" - has been increased to the maximum limit of 350kw, from the previous 250kw.

The FIA said the aim of these changes was to ensure the maximum time spent super-clipping on a qualifying lap was in the region of two to four seconds.

F1 has also increased from eight to 12 the number of circuits where a lower energy limit even than 7MJ may be applied. These are tracks where energy recovery is the most difficult, and tend to be those with long straights and few corners.

The in-race changes are mainly targeted at ensuring sudden speed differentials between cars in different deployment states do not become dangerous.

This was a key contributing factor in the high-speed crash involving Haas driver Oliver Bearman in the Japanese Grand Prix, as the Briton avoided the Alpine of Franco Colapinto after the Argentine drifted off line to discourage a passing attempt.

The maximum power of the "boost" mode will be capped at 150kw, or the car's existing deployment level, if that is higher.

Cars will be allowed to deploy the full 350kw (470bhp) of electrical power in acceleration zones out of corners, but will be limited to 250kw at other parts of the lap.

This means that in areas defined as "straight-line mode" zones, where the front and rear wings are open to increase speed, power will be at 350kw, but elsewhere maximum deployment will not be allowed.

This would mean, for example, that Bearman would have been able to deploy at only 250kw rather than the 350kw he was using in his incident.

An FIA statement said: "These measures are designed to reduce excessive closing speeds while maintaining overtaking opportunities and overall performance characteristics."

The sheer power of the new engines when on full deployment had raised concerns about how the cars would behave in the rain.

New rules, following feedback from drivers, have allowed for an increase in temperature of tyre blankets "to improve initial grip and tyre performance in wet conditions.

Maximum levels of electrical deployment will be reduced, to limit torque and improve car control. The exact limit has not yet been revealed.

A "simplification" of rear light systems to allow "clearer and more consistent visual cues to improve visibility and reaction time for following drivers in poor conditions".

In Miami, proposed changes to the race-start procedure will be trialled for potential introduction.

Starts are more difficult this year as a result of changes to the engine architecture and there has already been one near-miss this year when Liam Lawson's Racing Bull narrowly avoided ramming Colapinto's slow-starting Alpine in Australia.

To mitigate this, teams will trial:

a "low-power start detection system" capable of identifying cars with abnormally low acceleration.

In such cases, an automatic deployment of the MGU-K - which is not normally allowed at starts below certain speeds - "to ensure a minimum level of acceleration and mitigate start-related risks without introducing any sporting advantage".

Changes to restrictions of energy have been introduced to prevent cars arriving at the grid with low battery levels.
