To celebrate the announcement today of the winners of the second Challenge in the 2015 F1 Connectivity Innovation prize, we are running a JA on F1 competition, offering four lucky winners the chance to go behind the scenes at the Mercedes F1 factory.

Mercedes can clinch the Constructors' Championship this weekend in Sochi. How have the team done it? You can go behind the scenes and find out.

Thanks to our partner Tata Communications, we can take 4 lucky winners on an in-depth behind the scenes tour of the Mercedes AMG Petronas F1 team’s base at Brackley, England on Friday October 16.

You will get to go around the facility where Lewis Hamilton and Nico Rosberg’s cars are designed and built and where next year’s car is being developed at the moment. There will be lunch afterwards. James Allen will be there on the day, alongside the host, to answer any questions you may have.

Read on to find out how to enter:

The Second Challenge in this year's F1 Connectivity Innovation Prize was to design a prediction tool that asks F1 fans to forecast how each Grand Prix will unfold, and enables Formula One Management to rank the predictions and reward the fans that forecast the most accurate outcomes.

The three winning entries below will join the three from Challenge 1 at the Abu Dhabi GP next month. All six will be in with a chance of winning the Grand Prize - a cheque for $50,000 and a bespoke trophy.

Winning entry 1: team entrants Uros Strel Lencic and Andrew Fox, UK

Idea: The F1 Prediction Application would use a simple drag-and-drop interface to enable fans to tap into track and weather data and practice results to predict the outcome of each Grand Prix for each driver, including their pit stop strategies and tyre types. Whilst the race is in progress, fans could monitor their predictions against the action unfolding on the track in real-time. The F1 Prediction Application would enable Formula One Management to score and rank fans’ predictions after each Grand Prix.

Winning entry 2: team entrants Sandrine Partridge and John A Vasilakos, US

Idea: The Formula 1 Virtual Championship (F1VC) application would harness predictive analysis and gamification to boost fan engagement in F1® racing. It would allow fans to access, actively analyse and apply customised predictive forecasts against other fans in a virtual championship. The F1VC would have four levels for different fan types – Fan, Enthusiast, Aficionado and Expert – maximising opportunities to engage with different fans. The level would determine the number of variables the player would need to predict, i.e. a Fan would need to choose top 10 drivers for a race only, whereas an Expert would need to predict the top 10 for qualifying, and predict how many places each driver will move during the race, as well as their the pit-stop and tyre strategies. Players would score points for accuracy. The F1VC would assess and score the predictions of each player and rank them accordingly.

Winning entry 3: team entrants Giovanni Tomasell, Anthony Sapountzis and Andrew Romeo, Australia

Idea: The Prixdictor App would bring fans closer to the action by allowing them to choose a team and driver to manage and determine their race strategies. The app would give fans access to all practice data, weather conditions, race track history, current Championship standings and race results to guide their forecasts throughout the Grand Prix weekend. Fans would be awarded points throughout the race for their predictions and ranked accordingly. The winner would be the fan with the highest total points for a race. Prizes could be awarded for each race to build excitement around the Prixdictor App.
