Koenigsegg, the Swedish sports carmaker set to buy Saab Automobile from General Motors, is confident it can secure the company's future, its co-owner told Norway's Dagbladet newspaper Saturday.

GM, now in bankruptcy protection in the United States, put Saab up for sale in February as it bids to slim down its range of brands and become profitable again.

A Swedish TV report on Thursday said Koenigsegg and a group of Norwegian investors had signed a letter of intent to buy Saab.

Baard Eker, whose holding company Eker Group holds a 49 percent stake in Koenigsegg, appeared to confirm his interest in the Swedish automaker in an interview with Dagbladet.

"We think it is possible and we have several good solutions to bring with us into Saab," Eker said.

Commentators in Sweden have questioned whether Koeningsegg, a company which produces just 18 high-end luxury sports car a year and employs just 45 people, would have the financial muscle or industrial know-how to run Saab.

Founded in 1994 by chief executive Christian von Koenigsegg, a Swedish businessman, the company posted a turnover of 106 million kroner (10 million euros, 13 million dollars) in 2008.

However, Eker told Dagbladet that there were "several investors" backing his bid to buy the company from GM.

"But I don't want to comment on the amount of money and who is involved," Eker was quoted as saying.

"I want to make one thing clear. We are not buying Saab just to chop it up. That's not what we do," he added.
