It all began with my father having a race team for rally and track. So I grew up on the race track with him and my mum. Then I started carting when I was seven. I was doing pretty well, winning races and everything. I moved into cars when I was 16 with Formula BMW in Germany and then Formula 3.

I thought it would be interesting to be part of the race of the future, to complete a new challenge that was not around in motorsports before. I had the opportunity to join the Techeetah team and here I am.

There are lots of different ways to prepare. Obviously, I have to stay in the best physical condition, so I do a lot of cycling, rowing, a bit of cross-fit and in the winter I do cross-country skiing. Then for technical preparation we use the simulator which is part of our team preparation program. This is quite intensive. If I don't know a track, or if we want to simulate races, we can do that with the simulator.

It is general physical training because it is very difficult to replicate exactly what you have in the car, so I try to have top physical condition at all times. I also have to travel a lot, so it really depends on where I am and what time of the year it is. I always find solutions to use my time effectively.

There are a lot of differences. I would say the sound, and you don't have gears. Then charging the battery, saving energy, being very efficient and understanding all the numbers - it is quite a challenge for the driver. These are the main differences. But then it's not that different when you are actually in the car driving. In Formula E we have groove tires, which have a little less grip. But on the city track everything is so different, because the tarmac and asphalt are not like usual race tracks, they're streets. It alternates all the time - on some corners you have concrete, on some corners you have asphalt. There are a lot of unpredictable situations in Formula E.

It is the sport aspect of electromobility. That we can race electric cars, which a lot of people didn't know. We are pushing the limits and it also has a very big relevance for the automobile industry, which is shifting a lot towards electric cars. That's the importance of Formula E. And we also bring the race to the people in the cities, which is something very new too. By only racing in cities, we are sending a clear message that there can be clean racing in cities.

It has been great. I have been a fan of HUGO BOSS since I was quite young, because I was fan of Ayrton Senna and the previous partnership with his team. HUGO BOSS has always been identified with motorsport. When I was a kid, we somehow got connected with HUGO BOSS when I was carting and I went to the VIP shop and was quite proud. So when I heard I could have a partnership with HUGO BOSS, I was super happy. I personally identify with it, I think it's really good match and it fits my style as well. I like to look good, so it is right up my street.

It was my first victory of the 24 Hours of Le Mans in 2011, which was a very intense battle throughout the whole race. It was really a race that changed my career. Then in Formula E of course, my first podium in Santiago at the third event. That was a nice feeling as well.

The race in Zürich was very impressive, it was really cool. Rome was also nice.

It is very exciting, because we can go to breakfast in the hotel, walk to the track, and enjoy the local scene. This is a fun lifestyle merged with motorsport, which is a nice aspect. And then it is also very, very challenging. Sometimes race tracks are very narrow, tight and we are basically flirting with the walls all the time when we are racing. We cannot make any mistakes. It is very technical. Both aspects are great and it is really cool to race in the cities.

I am a bit in my own world when I am at the race track. When I drive, I don't know what is going through my mind. I am focused on driving and managing to race to the best of my ability, so it is very instinctive in that way. It is quite a nice feeling, because you are in the zone and all other things don't matter.

Well the first part is obviously on the podium, then with the team. We have some beers and we take a nice team picture to celebrate that. Because we're racing in cities, it is quite easy to find a good place to celebrate and there's an after-party. We have a few more drinks, enjoy the city, wake up the next day with a smile and enjoy that victory, enjoy the satisfaction.

I would love to have a race in Tokyo. I spent 15 years racing in Japan and I lived in Tokyo for 12 years. I think it is a fantastic city, amazing people and very futuristic, so a Formula E race in Tokyo would be very cool.
