Swire Renshaw Super Coupe Cup:
There are also track racing events for Polo G40's where they race against cars with similiar power to weight ratio's such as Renault 5 GT Turbo's and Honda CRX's. Because of the Polo G40's acceleration advantage (due to low down torque) the races have to be started with a rolling start and the Renault 5 GT Turbo's are allowed to run Group A carburetta's and uprated boost in order to keep their competitiveness up to rival the VW Polo G40 and despite this the Super Coupe Cup was still won by a Polo G40 this year with a race to spare.
