Recap: 2013 Australian Formula One Grand Prix is all about the rubber [w/spoilers]

A pre-season full of talking points was swapped for a brand-new set of talking points after the running of the opening grand prix of the 2013 Formula One season. The consistency of the regulations from last year to this year and the triplicate dominance of Infiniti Red Bull Racing meant that no one would have been that surprised if the relative order of things remained the same. But teams found so many ways to switch things up that, in typical pre-season fashion, no one was ready to make any bets on in-season performance, and a couple of surprising players suffered the ignominy of getting it really wrong: McLaren knew it was in trouble from the very first test, while Williams drivers applauded their car as the best in years, only to have Pastor Maldonado call it "undriveable" on the very first day of practice in Melbourne.
And then there were those Pirellis, the Italian company talking up the fact that its super soft tires would only go off so quickly that it would force teams to pit at least twice during the race.
Even then, no one could have seen the first round of pit stops beginning on Lap 5.

Lotus Evija's wild aero setup is detailed by chief aerodynamicist

The Lotus Evija is a car of firsts for Lotus. To that end, the company has spent a lot of time talking over the details. Today, we get to learn about the wild shape’s aerodynamics and what Lotus engineers were trying to accomplish. Richard Hill, chief aerodynamicist for Lotus takes a dive into all the details, and the video at the top of this post offers a great visual. “Most cars have to punch a hole in the air, to get through using brute force, but the Evija is unique because of its porosity,” Hill says. “The car literally ‘breathesÂ’ the air. The front acts like a mouth; it ingests the air, sucks every kilogram of value from it – in this case, the downforce – then exhales it through that dramatic rear end.” We can see what Hill means as we look at the Evija in photos. Instead of a regular front bumper, this one has pass-throughs that direct the air back into the side of the car. Lotus hasnÂ’t released the all-important coefficient of drag figure yet, but we have to imagine itÂ’s very low. The front splitter (below, left) is responsible for a few different things. The opening in the center takes in air to cool the battery pack that is mounted behind the seats. Then, the outer section of the splitter channels the air to the “e-axle” for cooling of the electrical components. And finally, it also produces downforce.  There are a couple more tunnels for air to pass through in the rear. These “holes” are likely the most distinctive design feature, especially when accentuated with the LED taillights. Hill says that these are also fully functional and help to reduce drag. “They feed the wake rearward to help cut drag,” Hill says. “Think of it this way; without them the Evija would be like a parachute but with them itÂ’s a butterfly net, and they make the car unique in the hypercar world.” On top of all these porous body structures, there are pieces that move. The rear wing can elevate upward from its flush body position and deploy into clean air above, creating more downforce. And then thereÂ’s an F1-style drag reduction system. This uses a horizontal plane that deploys from the car to make it slipperier through air. The final big piece of this puzzle is the underbody sculpting that directs air into the massive rear diffuser. This causes an upwash of air, in turn creating a massive amount of downforce. Hill sums it up quite nicely.

Lotus wants to find its first car, built by Colin Chapman

Lotus is looking for the first car its founder ever built. The Lotus Mark I, a trials special Colin Chapman built in a small garage in London in 1948, has been lost to history and the company has been trying to find it for ages. As Lotus is 70 this year, the first Lotus would be quite the icing on its birthday cake. Colin Chapman constructed the first Lotus in a garage that belonged to his girlfriend's parents, at the age of 20. The car was reportedly an instant competition success, but Chapman's competitive spirit meant he soon started on the car's successor, the Mark II, and sold the Mark I in November 1950 for GBP135 after advertising it in Motor Sport magazine. Both the Mark I and II were based on Austin 7 hardware, but the latter used different Ford engines while the Mark I retained an Austin 7 engine. Experiments with lightening the vehicle and developing a better suspension design were Lotus hallmarks from the very beginning, as the car needed to beat Britain's rough rally terrain and have enough grunt to climb hills. Lotus Engineering was set up in 1952, later spawning Team Lotus that started out in Formula 1 by the end of the 1950s — and the rest is history. But Lotus owes everything to the humble Mark I. "The Mark I is the holy grail of Lotus' history," Clive Chapman, Colin's son explains. "It's the first time that my father was able to put his theories for improved performance into practice when designing and building a car. To locate this landmark Lotus, as we celebrate the 70 th anniversary, would be a monumental achievement. "We want fans to take this opportunity to look in every garage, shed, barn and lock up they're allowed to," added Chapman. "It's even possible that the Mark I was shipped from the UK, and we'd love to know if it survives in another country." This means the first Lotus could even reside in the United States, if it is still in one piece.
