EXCLUSIVE-UPDATE 1-Motor racing-Hockenheim to host German GP - Ecclestone

* Hockenheim to host 2015 German GP * Nuerbuerging was due to under alternation agreement (Adds detail, quotes, July 19 race date) By Alan Baldwin LONDON, Jan 15 (Reuters) - Hockenheim will host this year's German Grand Prix in July instead of alternating with the Nuerburgring, Formula One's commercial supremo Bernie Ecclestone told Reuters on Thursday. "It's going to be at Hockenheim, we're in the middle of doing something with them. It can't be Nuerburgring because there's nobody there," said the 84-year-old Briton. Hockenheim hosted last year's German round under an agreement to share with the Nuerburgring, an historic circuit for champions Mercedes and their 'Silver Arrows', which is under new ownership. The 20-race 2015 calendar does not currently specify a venue for the July 19 grand prix. The season starts in Australia on March 15. "We've got a contract in place (with Hockenheim), we just have to amend the years of the contract. It was alternating with Nuerburgring so we'll just take that out," said Ecclestone. "Providing the contract goes through as we expect it to, we'll be in good shape." The news, while not entirely unexpected, will be seen as a setback to the owners of a circuit that Ecclestone twice tried to buy last year. Reports on Wednesday had indicated that Nuerburgring executives were hopeful of agreeing a new deal but were concerned about the costs involved. "Formula One is welcome at the Nuerburgring," CEO Carsten Schumacher told crash.net. "It provides worldwide television pictures, a positive image and would bring high sales to the region. However, Formula One has to remain affordable." Ecclestone told Reuters he had not discussed a deal with the Nuerburgring. "We wanted to buy the Nuerburgring, we made an offer and somebody topped us with a few dollars and bought it," he said. "And then they couldn't pay and it went on sale again. I said I'd be interested and then they found somebody else. So I don't know what's happening." Russian investor Viktor Kharitonin bought a two thirds stake, through a holding company, in the financially troubled Nuerburgring in October. The remaining third is held by GetSpeed GmbH, which is owned by a management consultant. Kharitonin controls Russian pharmaceutical company Pharmstandard, which has a market capitalisation of more than $1.08 billion, according to Thomson Reuters data. Capricorn and GetSpeed won a takeover battle in March to buy the track for more than 100 million euros, including debt, but Capricorn had trouble financing the deal. The European Commission also ruled last year that state aid given to develop the race track into a racing theme park was in breach of European Union rules and must be paid back.
