It's been a while since I last wrote, but the season seems to have gone so quickly for me.... It's hard to remember what happened at Zandvoort, let alone the Nurburgring and Brands Hatch too.

It has been a good season so far though, and that's encouraging. The results haven't shown it, but I've learned so much and it's been a really good experience. I'm so proud to be a part of Audi and the whole thing that goes along with that, and it's incredible to believe that we have been together this long already.

I knew it would be hard with a two-year old car and not being with one of the frontrunning Audi teams, and that's a little frustrating, but there are two sides to everything and it's good that there is less pressure on me as I learn what the DTM is all about. There's only myself and my team-mate, Christijan Albers, in two-year old cars, and it does make a big difference, even if the organisers do try to make the weight a little bit more even to keep us competitive with the newer models.

All I can do is take aim at Christijan. He finished as runner-up a few years ago and is well-respected in DTM circles so, if I can keep getting close to him - and beating him on occasion - then that's all I can do. The team has been great - it's not like going in to the series with a backmarker team, as it would be in any other series, because the team is fantastic. It's just the way it is, you have to earn your stripes and do a good job in a two-year old car so that you get to progress to a one-year old car, and then a new car. That's the way it works and it's really sensible because you only get promoted if you're up to it, if you've worked for it and if you've earned it.

You always hope that you're going to be in the newest car and the best team that you can be, and that's definitely a carrot for the future, but I really don't know what's going to happen next year - I'm not sure that many people do. I think it depends on what happens with both Mercedes and Audi, and deciding if they want to run two-year old cars. Mercedes, this year, has only run new cars and one-year old cars, so that's a possibility as well. It could depend on which drivers stay and which ones go. It's not my job to speculate on what's going to happen, but I hope, for myself, for the best possible outcome. There's not much I can do other than my best on the track. Hopefully, we'll get some good results in the last few races.

Brands Hatch was awesome - it was really nice to be back home, racing in front of my friends, my family and the fans. It's been a while - I don't remember the last time I raced in England, but it must be four or five years ago - so it was nice to be back. I had a lot of support, and it is the only track on the calendar that I actually know, so it was due to be a good race.

Even my mum was due to get in on the action, but she chickened out of a DTM Race Taxi ride around Brands. Audi are so fantastic that the Audi Sports Team Abt Sportsline sorted it out for her but, when it came down to it, she decided she couldn't face it. I don't know why, because she has been around Road America when they did 'taxi rides' there - but then that scared the living daylights out of her as well!

My dad's been in the two-seater Champ Car while I was out in the US doing that. He really really enjoyed that experience, so I hope I can get him out in a DTM 'taxi' at the end of the year. I was talking to Susie Stoddart's mum and dad at Brands after they had had a ride, and they were like 'I can't believe this is what you do....' - I wanted my dad to say that, rather than 'well, maybe you can brake a little later into the hairpin...'. He keeps on offering his coaching and advice which, considering he's never driven a race car, I find really funny.

Because of the high hopes and expectations at Brands, I was disappointed that we didn't get to qualify as normal following Gary Paffett's accident. It was really frustrating as I think we might have got into second qualifying.

Then, in the race, we got taken out twice and that relegated me to the back again. However, the times we were running in the race were well inside the top ten for the second and third stints and you can't wish for better than that. Racing is all about circumstance a lot of the time, and the fact that I couldn't qualify after spinning off in the changed session was why I was put to the back and got caught up in a lot of the mess.

Audi has had a successful season both in the DTM and in sportscars this season, having just clinched the LMS title with 'Rocky' and Alex, and won the race at Silverstone with Allan and 'Dindo' as well. I was there to see they worked so hard they really deserved it. They certainly seemed to be on the up now so let's hope that carried over into the final couple of races in the ALMS.

I was back in the United States for a week or so recently and got to go to Road America to watch the Audi ALMS team in action. I love Road America, even though I had the biggest accident of my career there. It's one of the best circuits in the world and it was good to be back, seeing some friendly faces, being there with Audi and generally seeing what the ALMS was all about.

I even did some commentary on the race at Road America with John Hindhaugh and Jeremy Shaw, and you may have spotted me on Sky television recently as well, offering my views on the IndyCar Series.

Seriously, I enjoy doing television - but I like doing it occasionally. I certainly don't want people seeing me in that role, as I am definitely still a racing driver, but getting to do that sort of thing gives you a different perspective on things - and that can only help.

Despite being back in the USA, watching racing from there and thoroughly enjoying my days with Champ Car, I can reassure everyone that I have no hankering to go back. I had a great time living in America, and wouldn't change any of it for the world, but I am completely committed to Audi and this programme now. I'm really happy to be back in Europe with the opportunities that I have got and can't see myself, out of choice, doing anything else.

The thing is, once you're in with a quality manufacturer like Audi, where everyone is really supportive, you just need to work really hard to be given the opportunity to move up and, hopefully, make a career out of whatever you are doing. There's no way I would jump ship and drive anything other a really winning car because nothing can compare to the opportunity I have at the moment. I also feel a certain amount of loyalty to Audi - they have been really good to me and I want to pay that faith back.

I'd like to think I can continue paying it back over the final three races of the year, but Barcelona is going to be a tough one for us as I've never been there before and only know it from the television and playing it on computer games. I'm really looking forward to going there though, as it's always a new challenge and a new adventure when you go to a new track and I can't wait to get that one under my belt. It's the last three stretch now and it is really really important to get some good results.

It's going to be a busy six weeks for me as, after Barcelona, we go to Le Mans, then I'm off to German school in Ingolstadt for two weeks to have some German classes ahead of the last race at Hockenheim - which I now know because that's where we did the first race at the beginning of the year.

Hockenheim is supposed to have a great atmosphere at the last race of the season - that is usually the same at the last race of any series, but this is supposed to be really special, so I can't wait to find out for myself. I really hope that we have a good race that weekend because there's nothing worse than finishing the season on a low note, and nothing better than finishing on a high note. Hopefully, now that I know the track, we can be a bit more competitive.

Speak to you soon,
Katherine
