Talking technical

Car dynamics

Average turn angle indicates the average angle of a circuit's corners expressed in degrees. The higher the average turn angle, the more acute the corners in the circuit's configuration and the greater propensity for understeer to compromise lap time. Average turn angle at Suzuka is 990 - which is below the average for the Championship. Suzuka is the only circuit on the Formula One calendar to feature a figure-of-eight configuration. The end of straight (EOS) speed at Suzuka was 311kp/h in 2006. The Japanese track ranks as having the 4th highest EOS speed on the 2009 calendar, and this is one indicator of the wing level typically selected to optimise the downforce/drag ratio. Meanwhile, Suzuka also has the 3rd highest average lap speed of any of the tracks on the calendar.

Pitlane & refuelling strategy

The pitlane length and profile contribute to the determination of the optimum fuel strategy. The pitlane loss at Suzuka is approximately 19.9 seconds, which is the 10th most penalising pitlane in the Championship. To complete a normalised distance of 5km around Suzuka requires 2.37kg of fuel against an average of 2.42kg per 5km across all circuits this season, ranking the circuit as the 5th least demanding in terms of fuel consumption.

Safety car

Another key contributor to the determination of race strategy is the likelihood of safety car deployments, which are influenced by weather considerations, the availability of clear run-off areas that allow racing to continue while recovery takes place and the circuit profile, especially the character of the entry and exit into turn one at the start of the race. There has been only one safety car deployment during the five previous races at Suzuka which means the circuit's character is unlikely to induce a safety car period.

Temperature, pressure & humidity

As an example, it is a long observed tradition that drivers arriving at Interlagos complain about a lack of grip and an absence of engine power. Having become acquainted with a baseline of engine and aerodynamic performance during the season, the climb to 750 metres above sea level for one of the final races can, courtesy of the reduction in air density, rob a Formula One car of engine power, aerodynamic performance and cooling. The losses can come close to double digit percentages and thus have a very real impact on car performance. Air density is a factor of the prevailing ambient temperature, which varies most significantly by season, air pressure which is closely linked to altitude and, to a much smaller degree, by humidity. Thus if races are run at the same time each year, the factor that tends to have the greatest bearing on air density is elevation. Suzuka is 50m above sea level and has the 6th highest average pressure (1,009 mbar) of any race venue in the 2009 championship. As a consequence, the circuit's ambient characteristics will have little effect on engine power.

What the drivers say

Thoughts on the Singapore Grand Prix
Nico: Singapore was good and bad. On the one hand, it was impressive to see how much the team has developed the car which allowed us to be right up there with the quickest teams. On the other hand, I robbed us of a very likely second place with a silly mistake.

Kazuki: For me, the Singapore Grand Prix was a solid but flat race, I didn't really have any bad moments, but there weren't any highlights either. We were strong all weekend, and consistent too, but at the end of the day I didn't manage to make up enough places during the race to get into a points-scoring position. I am now just hoping that it will happen at my home race later this week.

What we'll be doing between Singapore and Japan
Kazuki: I am flying to Tokyo on Monday morning for a sponsor day on Tuesday. I will then head out to Suzuka on Wednesday. My work won't be done after the race weekend though as I have two more sponsor days on the Monday and Tuesday after the race! It sounds very busy, but this year's schedule is better for me than the one I had last year when all the events were packed into the week before the race.

Nico: I am travelling to Hong Kong after Singapore for a day with RBS on Tuesday. I'll then make my way over to Japan on Wednesday.

About Japan
Kazuki: I kind of grew up around Suzuka. I have been to the circuit many, many times and it's the place where I started karting. I've also watched countless races there, not just Formula One races, but many other forms of Japanese motorsport, so going to Suzuka feels like going home. Apart from a short trip last April, I haven't been there for the past four years so it will be almost like a new experience. Overall, it's just a very nice place and I can't wait to get there.

Nico: I am now looking forward to Suzuka because I think we can do well there. Personally, I think the track is one of the best on the calendar, up there with Spa. It's also a good venue for Formula One because the fans are so enthusiastic which is always great.
