Back in the olden days, you just tied your cameraman right to the car:
Looks almost as goofy as Google Glass. Legendary F1 driver Jackie Stewart wore this stills-only proto-GoPro at the Monaco Grand Prix in 1966 (though not during the actual race):
Stewart ended up winning that race. I believe Stewart is also the model for this contraption, which looks like a film camera counterbalanced with a battery pack?
That couldn't have been comfortable. For some reason, neither of Stewart's helmet cams are recognized by Wikipedia as being the first documented helmet cam, which is instead attributed to a motorcycle race in 1986:
Coming into this season, Formula One made a lot of rule changes: new engines, better turbo systems, two different power sources (fuel & electrical), fixed-ratio gearboxes, etc. The cars had to be redesigned from top to bottom. Whenever a situation like this occurs, there's an opportunity for technical innovation (rather than the gradual improvements that tend to occur when the environment remains mostly unchanged). This year, the Mercedes team built their engines to get more out of the new turbo system than the other teams.
What Mercedes' boffins have done, according to Sky Sports F1 technical guru Mark Hughes, is split the turbo in half, mounting the exhaust turbine at the rear of the engine and the intake turbine at the front. A shaft running through the V of the V6 engine connects the two halves, keeping the hot exhaust gases driving the turbo from heating the cool air it's drawing into the engine.
Aside from getting cooler air into the engine and extracting more power (maybe as much as 50 horsepower), this setup also allows Mercedes to keep drivetrain components closer to the center of the car. It also allowed the team to use a smaller intercooler, which cools off the heated air before going into the engine, compared to the rest of the cars.
And the result so far? Utter Mercedes domination. Out of the three races this year, the two drivers for the Mercedes team (Lewis Hamilton and Nico Rosberg) have three first-place finishes and two second-place finishes (Hamilton had to retire with engine issues in the first race). Mercedes was certainly competitive last year, finishing second, but Red Bull-Renault easily beat them in the points race and one of their drivers finished 1st in 13 out of 19 races. More relevant to the discussion here is how easily these races are being won by Mercedes. In each of the three races, a member of the Mercedes team qualified in pole position, recorded the fastest lap, and beat the other teams' drivers by more than 24 seconds in each case. To put that last stat in perspective, last year the winning team beat the second place team by more than 20 seconds in only three races, with the margin typically in the 3-10 second range.
Update: I said earlier that one of the changes was "no refueling during races" which has been the case for a few years now (hence the 2-second pit stop). Also, this video is a great explanation of how Mercedes turbo is designed and how it helps make their car go faster:
Watch Ferrari's F1 pit crew do a pit stop in a bit over two seconds:
I wish this were in slow motion because I've watched this three times now and I still cannot understand how it's done. My favorite part is how calm they all are about it. Here's a longer video that shows the process over and over from several points of view, including from a GoPro mounted on the chest of the wheelgun man:
Watch for the guy on the front jack pirouetting out of the way. I would love to read a long piece on how F1 pit crews train and practice. There are tantalizing bits in shorter articles, like this one from Autosport.com:
With three people per wheel, two jack operators, and a handful of mechanics fulfilling other functions, each pit crew comprises nearly 20 people.
Each is trained for a specific role and teams take their preparation as seriously as drivers', managing crewmen's fitness and diet.
They are drilled incessantly at both the factory and during race weekends, with hundreds of pitstop practices until the process is instinctive.
Although problems such as faulty guns are rehearsed, everyone focuses on their own job -- in a two-second pitstop, there is no time to see what everyone else is doing. By the time an error has been alerted, the car has often already pulled away, as was the case at the Nurburgring.
Teams now spend huge sums to design their own equipment and improve the fitness of their teams who also work as mechanics. McLaren is working with the English Institute of Sport to hone their 24-member team's technique while Williams has partnered with Olympic champion Michael Johnson's Performance Center to work on everything from diet to eye-hand coordination to core strength.
Training has also been ramped up. Most teams have rigs to practice on in the factory and pit stops are practiced as many as 70 times over a typical race weekend. Each stop is timed and videotaped for later review.
"When you had to go from 3.5 seconds down to a lower number, then you really need to be very specific and accurate on how you train because everything needs to be very synchronized to achieve that level of fast time and consistency," said Williams' chief race engineer Xevi Pujolar, whose team had its fastest pit stop this season in Spain after making changes to its crew but still is almost a second behind the top teams.
"There still a lot of room for improvement and we are working hard to catch up to these guys that do close to two seconds," Pujolar said. "If you look at video of pit crew and how they move during pit stop, everything is so well coordinated. To achieve this level of coordination on every pits stop requires a lot of training."
Alain Prost retired from F1 racing for the final time in 1993, with his last race coming at the Australian Grand Prix in November. He finished second in the race to his fierce rival Ayrton Senna but handily won the World Championship to the runner-up Senna. But the two of them raced for one final time in December of that year...driving go-karts.
Predictably, the pair took it very seriously: four-time world champion Prost having tested extensively before the event; Senna, a three-time title holder, having a kart shipped to Brazil so that he could practise.
Speaking of what fast looks like, here's a pair of synced videos that show just how fast F1 cars are. On the left are drivers participating in a track day, that is, normal folks who want to drive their cars fast on a real race course. A couple of them look like actual GT cars and are moving pretty quick. On the right, you've got F1 cars on the same track. It's not even close:
