World Solar Challenge: Day 3 wrap

Here is another distance/time plot for non-trailered Challenger class cars. Race leaders Twente (21) and Nuon (3) are so close that the orange line is hidden under the red – it will come down to race strategy and managing the weather issues. Michigan (2) is next in blue (still suffering the curse of third), followed by Tokai (10). Punch (8) served a one-hour penalty in Kulgera for alleged reckless driving by their media car. They are appealing this, and are also clawing back lost time, as the dark green line shows. Next come Stanford (16), Kecskemét (23), Arrow (30), EAFIT (5), and Western Sydney Uni (13). UKZN (14) and Blue Sky (77) have been duelling for the next spot, and it looks like the dashed line for UKZN is just a whisker ahead now. After them come Goko High Scool (25) in black, Jönköping Uni (46), Nagoya (47), Kanazawa (51), Principia (32), Anadolu (36), KUST (82), MIT (7), and Beijing (80).

Sadly, Adelaide (9) report having trailered. Some of the other cars listed might have trailered too. For example, the way that MIT (7) keeps driving after 17:00 suggests that they might have trailered.

For the Cruiser situation, see my previous post. In other news, Bochum are spending the night in a gym, while Nuon are camping in the dust. For photos galore, see MostDece’s blog, and for video, see Twente’s (Dutch) report. The Coober Pedy weather forecast for tomorrow is for cloud clearing.

Below is the kind of chart I did in 2013 (as always, click to zoom). Data is taken from the official timing board, rather than from GPS. Here the distance is horizontal, and the vertical axis expresses time. Specifically, it expresses how many hours each car is behind a car driving at exactly 97.42 km/h. Why that speed? It’s the speed which would get a car into Adelaide at exactly closing time on Wednesday. None of the actual Challengers can quite manage that, of course, so they will all arrive later. The expected arrival times on Thursday and Friday can be estimated by extrapolating to the right-hand axis. This means that, for this chart, faster cars are at the bottom. It must be emphasised that the official timing board may contain errors – for example, Western Sydney (13) is recorded on the official timing board as arriving at Katherine at 05:43:55 hours into the race, while my GPS-based chart for Sunday shows it arriving much earlier.

World Solar Challenge: Evening, Day 3

Here are the World Solar Challenge GPS positions as at 17:00 Tuesday October 20 (Darwin time) – the finish of Day 3 of the race.

Calculated road distances below are approximate, based on interpolation between the known road distances to control stops. The second road distance shown (in grey) is adjusted to compensate for GPS delays. The top fifteen Challenger teams are Twente (21), Nuon (3), Michigan (2), Tokai (10), Punch (8), Stanford (16), Kecskemét (23), Arrow (30), EAFIT (5), WSU (13), UKZN (14), Blue Sky (77), Goko High Scool (25), Jönköping Uni (46), and Nagoya (47) in that order. Nuon is camping just shy of Coober Pedy, with Twente still a whisker ahead of them.

In the Cruiser class, Kogakuin (88) came into Alice at 11:17, Eindhoven (40) at 12:01, and Bochum (11) at 16:00. Minnesota (35) and Sunswift (75) had to make it to Alice by 17:00 but, sadly, they did not. See the tracker page, timing board, and social media for continued updates.

World Solar Challenge: Afternoon, Day 3

Here are the World Solar Challenge GPS positions as at 14:35 Tuesday October 20 (Darwin time) – Day 3 of the race.

Calculated road distances below are approximate, based on interpolation between the known road distances to control stops. The second road distance shown (in grey) is adjusted to compensate for GPS delays. The top five teams are Twente (21), Nuon (3), Michigan (2), Tokai (10), and Punch (8), in that order. They are closing in on Marla (which is not a control stop). In the Cruiser class, Kogakuin (88) is 44 minutes ahead of Eindhoven (40), which probably puts them in the lead, even taking Eindhoven’s passenger into account. Per the regulations, “Cruiser Class and Adventure Class will be timed in two stages: Darwin to Alice Springs, and Alice Springs to Adelaide.” They are therefore stopping there for the night.

Blogger MostDece has posted a photo of the Alice Springs board. There are also Twitter pictures of Eindhoven, Blue Sky, EAFIT, and Goko High School arriving at Alice, and a plethora of wonderful photographs from the Zero to Darwin Project. See the tracker page, timing board, and social media for continued updates.

It is worth noting that there are now effectively two races going on – call them A and B. The A race is decided on time (or, for the Cruiser class, points). The B race is for cars that have been trailered, and is decided on number of kilometres travelled under solar power. We are now seeing several cars in the B race, but it’s hard to tell which of those are ahead of the others [update: Lodz (45) and HK IVE (33) have also trailered, but Stanford (16) has not]. At the end of the event, the A cars will all score ahead of the B cars (in 2013, the top B Challenger scored 11th overall). Note also that the Barrow Creek control stop closes at 16:00 today.

21 Twente Netherlands (Red One, Challenger) Approx 1933 km from Darwin 92 km/h (Adjusted 1937 km from Darwin)
3 Nuon Netherlands (Nuna8, Challenger) 2 km behind Twente 92 km/h (1 km behind Twente)

World Solar Challenge: Morning, Day 3

Here are the World Solar Challenge GPS positions as at 09:59 Tuesday October 20 (Darwin time) – Day 3 of the race.

Calculated road distances below are approximate, based on interpolation between the known road distances to control stops. The second road distance shown (in grey) is adjusted to compensate for GPS delays. The top five teams – Twente (21), Nuon (3), Michigan (2), Tokai (10), and Punch (8), in that order – have all reached Alice Springs, although Nuon seems to have surged ahead since then. The weather outlook seems to have improved slightly, although teams carrying a meteorologist along will probably have a strategy edge. Punch were initially given a one-hour penalty, but apparently a phone call put this on hold. Eindhoven have a non-functioning GPS, so it’s not clear where they are.

Western Sydney (13) took pictures on reaching Barrow Creek. Liberty confirm that they are partially trailering, because their car doesn’t meet the minimum speed requirements. They will be ranked by number of solar-powered kilometres travelled. Cambridge had to partially trailer to Tennant Creek. See the tracker page, timing board, and social media for continued updates.
