The
RB18
was
a
complete
redesign,
with
a
Red
Bull
Racing
Power
Train
under
the
cover,
18-inch
tyres
replacing
the
13
rubber
that
had
been
used
for
more
than
50
years,
a
completely
different-looking
rear
wing
and
a
new-look
front
wing.
But
it
was
the
underbody
and
diffuser
that
was
to
make
the
biggest
difference.
It
was
designed
to
reduce
the
dirty
air
pushed
out
by
the
cars
so
it
would
encourage
closer
racing.
Max
Verstappen
and
Sergio
Perez
dominated
the
season,
taking
17
wins
between
them
and
a
total
of
28
podiums,
including
five
one-two
finishes.
Max
took
his
second
title
and
the
Team
claimed
their
first
constructors'
title
since
2013.
