Formula One teams have decided to delay the introduction of new environmentally friendly engines by a year until 2014, a measure that has been greeted with alarm by the sport's supremo Bernie Ecclestone and the organisers of many of the grands prix.
However, in a move to quell Ecclestone's and the race organisers fears that such a measure will see a drop in attendance figures the maximum rev limit of the engines will be increased to 15,000 from 12,000.
The decision to switch from four-cylinder 1.6-litre engines introduced in 2013 to V6s of the same size a year later was made by F1 bosses last week and following a fax vote the switch was ratified by the World Motor Sport Council.
Ecclestone was against the switch to the new engines from the current 2.4-litre normally aspirated V8s, as he said there would be a lot less noise and as a result be less exciting to watch.
The organisers worries were that the change could result in a drop in attendance figures, which is their only source of income.
