Pull out your abacuses, here’s the China GP’s tech side

Share This Post

As part of its pre-race info drop, the Williams team this year (maybe last, too, I don’t recall) is releasing technical information for each circuit.

Now, I’m not engineer, don’t even play one on TV (or the Interwebs), so I’ll leave it to others to carry a few ones, plug in a few additions and subtractions and tell us what these details might show.

You can get a sense of how a slightly more fuel efficient engine is a boon, especially at the start of the race. By my likely to be wrong eyes, if you could pull out four or so more laps than your competition, you’re closing in on a third of a second advantage.

Anything else strike anyone?

Circuit Statistics Legend
Kilos per lap: This indicates the amount of fuel required to complete a lap of each circuit normalised for a 5km lap, thereby indicating the relative fuel demands of each circuit.

Time loss per 5km of fuel: This metric indicates the relative penalty at each circuit of carrying 5km of fuel.

Vmax: The highest top speed at each circuit, one variable in the aero map for each track profile.

Average speed: Velocity averaged over the circuit distance, another variable in determining the aero map.

Average corner speed: In contrast to Vmax which indicates highest speeds achieved normally on the longest straight of the circuit, average corner speed indicates the aggregated speeds through all corners on any given circuit, providing an insight to the nature of the circuit profile.

Turn angle: 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.

Temperatures: Average ambient and track temperatures have a bearing on many variables, from tyre warm-up to significant car cooling requirements. And if you need to open the bodywork for cooling, you have to consider the potential drag penalties.

Greatest power reductions: Air density has a bearing on engine power and the most influential factor in air density is air pressure, determined by the elevation above sea level.

Pitlane loss: The time lost (excluding stationery time) entering and exiting the pitlane, providing an indication of not just the pitlane length, but also its profile.

Pitlane length: The entry to exit distance of each pitlane.

Safety cars: A variety of past statistics indicates the likelihood of the safety car’s possible intervention.
