Japan preview quotes: BMW

Nick Heidfeld: "I'm thrilled that my favourite Formula One circuit is back on the calendar. It will be interesting to see what changes it has in store for us. I know the track has been partly resurfaced, and there's always the possibility of the forces of nature intervening - we've already had an earthquake and a close call with a typhoon. The weather is always an issue and there's been torrential rain often enough in Suzuka. It's quite a long circuit, very varied, and it flows beautifully. The first section with its double-apex right-hander and sequence of esses is really superb. But you have to get into the flow properly; if you make a mistake in one turn, you'll mess up all the rest.

"I really enjoy going to Japan. The first time round I didn't immediately take to it, but since then I've become a great fan. I just love the food and the unique atmosphere. I'll be spending a few days in Tokyo ahead of the race in Suzuka."

Mario Theissen, BMW Motorsport Director: "It's one race chasing the next on the home straight of the 2009 Formula One season. Seven days after the night race in Singapore we've got the next round in Suzuka, Japan, which completes the back-to-backs in a region that is extremely important for the BMW Group.

"This circuit is one of the most challenging for the drivers, making it a real favourite among them and the fans. A well-balanced car is a must in Suzuka. But it's a tough track for the engine experts as well: in the ultra-fast 130R turn you get lateral acceleration forces of up to 6g and it's essential the oil keeps flowing."
