Following are the main changes made to the regulations governing Formula One to be introduced from 2017 onward:

Bodywork and tyres

For possibly the first time, the look of the cars has been a central part of the creation of the 2017 regulations. The cars are set to look much more “aggressive” and will be heavier and wider – and run on much wider tyres. The wings will also be wider and the rear wing will be lower than as in 2016.

 

Tyres

The front tyres will expand from a 2016 size of 245 mm wide tread to 305 mm. The rear tyres will expand from 325 mm wide tread to 405 mm wide tread.

 

Wings

The front wing will expand from 1650 mm span to 1800 mm. The rear wing will expand and shrink from 750 mm wide and 950 mm high to 950 and 800, respectively.

 

Weight

The overall gross weight will increase from 702 kg maximum to 722 kg plus tyres (estimated at five kgs).

 

Speed

The various and many changes are expected to increase speeds by more than five seconds a lap due to, in particular, “aerodynamic rules evolution, wider tyres and downforce.”

The final generation 2016 cars were fast enough to set track records at many circuits including Bahrain and Austria. World champion Nico Rosberg recorded a pole lap time at the Hungarian Grand Prix that was more than two seconds faster than in 2015. There's a good chance, based on what F1 experts are saying, that the 2004 Albert Park Grand Prix Circuit lap record held by Michael Schumacher will be beaten in 2017. The question is by whom?  

 

Engines

Despite much opposition to the hybrid turbos, they will continue next year and remain until at least 2020.

The engine token system has been abandoned and will no longer be used.

The price of engines, for customer teams, has been reduced by one million Euros, per season, and a further reduction by three million Euros is set for 2018.

A boost pressure constraint is to be introduced in 2017. 

Drivers are to be limited to a maximum of four power units per season, instead of five as in 2016.

 

Sound (and fury!)

Calls for more noise from the engines have been heard. Higher revving engines with an increased level of noise are promised. A ‘sound generator to boost the volume' will be ushered in. 

 

Safety Car starts and re-starts

If a race starts behind a Safety Car, as in Monaco, Britain and Brazil in 2016, it is expected that a standing re-start will be made when the Safety Car returns to the pits. This proposal is unconfirmed.
