The BMW and SEAT performance ballast is changing for Porto

The BMW and SEAT drivers have been given a slight weight reprieve for the Race of Portugal, the next round of the World Touring Car Championship which will be held on the streets of the city of Porto.

Using the sport’s complicated performance ballast rules, the BMWs were given a 30kg weight increase for last weekend’s Race of the Czech Republic at Brno, stemming from the fastest lap times the BMWs had posted in the preceding two rounds of the championship.

Accordingly, the BMW 320TCs will shed 10kg of performance ballast, but will remain the heaviest cars on the grid at 1200kg.

The SUNRED outfit’s switch from two-litre turbodiesel engines to the latest-spec 1.6-litre turbocharged petrol engines saw five of the outfit’s six SEATs forced to run with the maximum 30kg of performance ballast under the ‘new car’ rule.

But with the outfit having completed two rounds under its new car/engine combination, the sport’s officials have decreed that they can run 60kg lighter than their Brno weight, at 1130kg.

The ultra-competitive Chevrolet Cruze – winner of nine of the ten races so far this season – will remain as the most-ballasted car on the grid at Porto, running the maximum 40kg of compensation weight to tip the scaled at 1190kg.

The Polestar Racing outfit’s single C30 for Robert Dahlgren – having debuted its 1.6-litre turbocharged engine at Brno – will run the Porto round with the ‘new car’ ballast – before it becomes eligible to run under the performance ballast rules.
