PQ25 platform set to be engineered for all-wheel drive to underpin an Audi S1, Polo R and CrossPolo

Volkswagen Group is engineering its PQ25 platform for all-wheel drive, Audi sources have revealed.

This will allow Audi to create a proper S1, following the decision not to use the name on the current range-topping A1 launched at the Paris motor show, as it’s front-wheel drive.

The decision to re-engineer the platform should also lead to two other models from VW: a Polo R and a CrossPolo.

VW is understood to have taken development of the Polo R to an advanced stage, but, like Audi with the S1, made the decision against putting into production due to the issue over all-wheel drive.

Being able to produce a minimum of three models of the all-wheel drive PQ25 platform is believed to have convinced VW Group that the engineering costs would be worthwhile.
