the sidepods from the front to the back.
“Two strong vortices [coming off the rear
wing] suck in a lot of the rear-wing wake and,
as a result, what the following car sees is a much,
much cleaner fl ow. So we have a massive reduction
of the loss of downforce for the following car.”
F1 hopes to reach an agreement with teams
about the new rules by 15 September, so the
process can then move forward for ratifi cation
by the FIA World Motor Sport Council before
the end of October.
The concept outlined here will likely evolve
as the teams and FOM work through the rules
in more detail. Already there is talk that the
wide and simple front wing may be modifi ed.
Tombazis added: “The front wing, we are
still not completely pleased about. Both from
an aerodynamic point of view and from an
aesthetic point of view.
“So we are trying to make it better in both
aspects. There are good reasons why the wing
is very wide, aerodynamically, but we agree it
is not the best visually.”

  electronics


• Reduction in the use of car-to-pit
  telemetry


• Introduction of more standard parts


• Simplification of the lower part of
  the chassis


• Reduction in the number of personnel
  at race weekends


• Reduction in the weight of an F1 car


• A simplified fuel system


• Simplified radiators


• Frozen specification of gearboxes
  for five years


• Hydraulic suspension banned


• Standard wheel rims


• Standard wheel hubs/nuts and
  pit equipment


• Standard brake systems


• Restrictions on the use of certain materials


• A 40% reduction of windtunnel time
  for teams

1 The rear wing features a

simple endplate to reduce

the effect of turbulence

and helps divert airflow

high up with a twin vortex

2 The taller diffuser is

much more powerful

than on current cars

3 The stepped plane area

is not totally flat because

there is the chance to house

Venturi channels in this area

4 The halo has a better

integration with the

overall car design

5 The start of a big Venturi

channel, which begins where

the current bargeboards are

6 The wheel rims could

feature covers to help

manage airflow better and

make it less disruptive

7 The low nose without

turning vanes shows the

simplified aerodynamics

8 The front wheels

are covered with two

deflectors, which help

prevent outwash of dirty air

9 The brake ducts are

simplified and have less of

an aerodynamic influence

10 The endplates

are rounded to help

minimise the risk of

punctures in incidents

11 The nose will be low

again, returning to how

it was in the early 1990s

12 The mainplane is

slightly arched upwards to

improve airflow underneath

the car and help feed the

ground-effect tunnels
