The hot hatch would break new ground for the supermini but could tread on the Golf GTI's toes. VW is yet to decide if it will reach production
Insiders at Volkswagen have revealed that prototypes of a high-output Polo R have been built for evaluation purposes, but there is no decision yet whether the model has a production future.
The modification is relatively easy because the Polo GTI's 2.0-litre engine is the same unit used by the Golf R.

"There is enough room for all the extra cooling in the Polo, for sure," said Ralf Kölling, Volkswagen's director of small car lines.
The Polo could also accept the Golf R's four-wheel drive system because the cars share the same MQB platform.
But the extra weight and cost might push the Polo too far into Golf territory.
Other Volkswagen Group brands plan to use the 300bhp R engine in hot Seat and Skoda models, which could also help make a case for the Polo R.
The R brand is already confirmed to be expanding, with the expected launch of a T-Roc R tipped for next year as an indirect replacement for the Scirocco R.
Volkswagen has also toyed with rallying-inspired sporting Polos, with the 217bhp, 2500-unit limited-run Polo R WRC of 2013 being the closest thing to a full-blown Polo R model yet made.
