FEATURE: SKODA AP4+
The regulations stipulate that cars
must run 1.6 litre turbocharged engines,
however, because of the cost of
developing these units, it was agreed that,
initially at least, engines of up to two litres
would be allowed.
This means that the cars, including the
Hyundai driven by Hayden Paddon, and
Inkster’s Skoda, are classified as AP4+.
“In many ways, the Skoda is very similar
to the other AP4 cars, with the obvious
difference being the engine, which is a 1.8
litre turbo motor that has been used in
many different VW group cars, including
the Skoda Octavia RS,” Inkster says.
Coupled with a Sadev 6-speed gearbox,
the Skoda is an impressive
machine, although Inkster hasn’t
really had a clean run in the car so far this
year.
Like any new car, however, reliability is a
work in progress, and it’s the smaller items
WHAT IS AP4?
MotorSport New Zealand (MSNZ) and
the Confederation of Australian Motor
Sport (CAMS) collaboratively developed
the AP4 technical regulations for a
new generation of 4WD turbocharged
rally car eligible for competition in
both National and International events
within the Asia-Pacific region.
The official definition of the category
is listed as:
GROUP AP4 is a rally category
developed for National and Regional
competition for forced induction 4
wheel - drive cars.
It is based upon the principles of the
FIA Group R5 category and is intended
to create cars of similar performance,
as well as that of the Super 2000 Rallies
and Group N (including R4) categories.
The concept of the AP4 Rally Car
is to produce a build specification
/ technical regulation that ensures
cars can be locally built from locally
sourced component parts, controlled
either directly or indirectly by the ASN
[MotorSport NZ or CAMS].
The overriding intention is to
ensure that the build specification
is controlled, whilst guaranteeing
that initial build, as well as ongoing
maintenance costs, are kept within
realistic bounds.
Manufacturer / Dealer involvement is
encouraged with respect to promoting
their brand through support of
Competitors / Teams in building and
campaigning their marque.
