STOCKHOLM (Reuters) - Swedish truckmaker Scania said on Tuesday it had filed an appeal against a decision by the European Commission to fine it 880 million euros ($1 billion) for taking part in a price fixing cartel.

The European Commission announced the fine in September, saying Scania had colluded with five peers, fixing vehicle prices to enable them to pass the costs of required environmental improvements on to customers.

"In the appeal, Scania contests the findings and allegations made in the Commission's decision," Volkswagen-owned VOWG_p.DE Scania said in a statement.

In July, Volkswagen's MAN, Daimler DAIGn.DE, Volvo VOLVb.ST, Iveco CNHI.MI and DAF PCAR.O admitted to taking part in the cartel in return for a 10 percent cut in their fines. Scania did not settle.
