F1 to make rule changes from next race in Miami after engine concerns

LONDON, April 20 : Formula One teams and stakeholders agreed unanimously on Monday to engine rule tweaks aimed at improving the racing and driver safety from the next race in Miami on May 3.

The sport this season started a new era, with the hybrid power units now split roughly 50-50 between electric and combustion power.

Some drivers have complained over the first three races about having to 'lift and coast' into high-speed corners so the combustion engine can recharge the battery, and have aired safety concerns regarding the start and speed differentials during the race. 

They have also had to contend with 'super-clipping' where the power unit automatically diverts energy from the engine to the battery, slowing down the car even if the driver is flat on the throttle. Red Bull's four-times world champion Max Verstappen has questioned his future in the sport.

The governing International Automobile Federation (FIA) said in a statement that an online meeting with the 11 team bosses, power unit CEOs and Formula One had agreed a number of in-season "refinements" that would now be put to a virtual vote.

"The proposals agreed today... will be implemented from Miami apart from the race start changes that will be tested in Miami and adopted following feedback and analysis," it said.

MORE CONSISTENT FLAT-OUT DRIVING 

The FIA said energy management parameters would be adjusted for qualifying, a key area of concern, with a reduction in maximum permitted recharge from eight megajoules to seven to encourage more consistent flat-out driving and peak 'superclip' power increased from 250kW to 350kW to reduce the time spent recharging. 

In the race, measures were introduced to reduce excessive closing speeds and limit sudden performance
