Honda can develop F1 engine in 2015

The Japanese car manufacturer and F1 race director Charlie Whiting had a meeting last Monday whereby the FIA agreed to amend some of the engine rules.

Whiting has now given Honda the all-clear and will be allowed to make certain modifications in order to maintain a degree of competitiveness in line with its three rivals.

"As each of the four 2015 manufacturers will have an homologated power unit at the start of the season, we believe it would be fair to ensure that each of them enjoys equal opportunities for upgrades during the season," wrote Whiting on Friday.

"We will therefore allow the new manufacturer to use the same number of tokens that the other three manufacturers have available to them, taken as an average of the three.

"For example, if the three 2014 manufacturers have eight, seven and five unused tokens respectively at the start of the season, then the new manufacturer will be allowed to use six during the season (the average rounded down to the nearest whole number)."

Under the complicated system, the manufacturers have 32 tokens (in total) to use this season, decreasing to 25 in 2016 and 20 in 2017.
