Best result so far for Copper Horse Racing, as David Rogers gains 12 places during the race to finish P20.
Dried off and ready for a slightly longer race 3, car 59 was lapping well in practice around Circuit de Barcelona-Catalunya, but stringing together a clean lap during qualification proved difficult. A familiar track to Formula 1 fans, the Barcelona circuit is quick to punish mistakes with lost time. In the twisty final sector, misjudging slow corners such as the 180 degree bend starting at ‘La Caixa’ (turn 10) will soon undo any gains made earlier in the lap. And getting a clean exit out of
the final chicane is crucial to cutting the timing beam at top speed.
At the end of qualifying, Copper Horse’s 2015 Lamborghini Huracan was lined up in 32nd position, 2.874 secs off the fastest Tier 10 lap time of 01m:45s.243 set by Italian driver Gianluca Cappellini in a Porsche 991. In Tier 1, Maciej Malinowski – also driving a Porsche – travelled the same distance in an unfathomable 01m:42s.684.
But the race is won after 90 mins not over a single lap, and a lot can happen in that time – especially when you have a 1047m long start/finish straight terminating in a sharp right-hand turn! Plus, there’s a refuelling stop to calculate – get it right and you’ll fly home with fumes in the tank, get in wrong and it’ll cost you valuable lap time.
Following last week’s rain-soaked race at Donington Park, competitors were happy to see a change in the weather at the Barcelona circuit. For race 3, sim-racing league organisers Apex Online Racing had dialed in dazzling sunshine, catching drivers in the eyes coming into sector 3 and driving out of sector 1.
Blinding the Technology
Linking this scenario to our threat modelling work for automotive, it’s worth mentioning that it’s not only the driver that gets blinded by the sun. Bright light can trouble advanced driver assistance systems (ADAS) too. There are examples on YouTube showing how Tesla’s lane change feature can fail when sun glare prevents the vehicle’s forward-facing cameras from distinguishing the white lines on the road. Similarly, Comma.ai’s ‘Openpilot’ – a lower cost alternative for non-Tesla owners, which is based on a smartphone that looks out through the vehicle’s windscreen – has also been observed to lose tracking under sunny conditions.
Other products besides ADAS can also be vulnerable. If you have a robot vacuum cleaner, you might want to close the curtains before letting it loose, as Terence Eden (@edent) and many other customers have found that streaks of sunlight can stop such gadgets in their tracks.
Back in Barcelona, it was hard to blame the sun for a tap on the side that nudged car 59 off the track as close racing was pushed to its limit. But even with a couple of lost places, Copper Horse Racing’s driver David Rogers was still well up on qualifying, finishing P20 and bringing momentum into race 4. It wasn’t as comfortable a drive as it appeared though, as a mischosen set of brake pads struggled to last the full 90 minutes with the car suffering from brake fade in the second half of the race.
Podium Positions and Driver of the Day
At the top of the table, Canada’s Justin Dawson took the #1 spot for the second time in a row, while P1 qualifier Gianluca Cappellini slid back one position in the race to come second. Completing the podium, for the third time in three races, Dave Bramhall finished P3.
Driver of the day – a stat based on the number of positions gained during the race – goes to Marc André Stoltenberg of Germany in car 24 who gained 18 places to finish P16.
Next week, the driving conditions will change again as competitors experience the league’s only night race of the season at Laguna Seca Raceway – a scenario that will make track knowledge more important than ever and the track’s infamous corkscrew even more perilous.
Tune in next week for more updates on car 59’s progress in Apex Online Racing’s Assetto Corsa Competizione GT3 League Season 7.
