SUZUKA, Japan - Red Bull driver Sebastian Vettel, on the verge of claiming his fourth consecutive Formula 1 championship, doesn't think his overwhelming dominance has made the sport less interesting for fans.Mercedes driver Lewis Hamilton was quoted after the 2013 Korean GP (Oct 6) as suggesting that Vettel's dominance risked putting fans to sleep, similar to the era when Michael Schumacher was dominating ten years ago with five straight titles from 2000-04.TITLE IN THE BAGVettel has won eight of 14 races in 2013 and will be aiming to clinch his fourth successive title at the 2013 Japanese GP. Vettel needs to win and have nearest rival Fernando Alonso finish worse than eighth.If he wraps up the title at Suzuka, Vettel will join compatriot Schumacher and Argentine Juan-Manuel Fangio as the only drivers to win four consecutive titles. When asked about Hamilton's comments, Vettel said there is a big difference between his wins and those of Schumacher.Vettel won the Singapore GP by 32.6 seconds over Alonso and was booed when interviewed on the podium but said his 4.2-second win over the Lotus pair of Kimi Raikkonen and Romain Grosjean at the Korean Grand Prix was more typical of his victories.'BIG DIFFERENCE'Vettel said: "I think it's very different. I think there is probably one race which was a bit of an exception. If you take Singapore, the gaps we had and were able to build up were incredible. ... If you take Korea, which is more similar to Spa, the gap was something between three and six seconds for the whole race. If you look at 10 years ago, it was more like thirty to sixty seconds which is a big difference."Vettel's latest victory in Korea stretched his lead over Alonso to 77 points with five races left.Hamilton, who finished fifth in Korea and is fourth in the standings, later backtracked on his comments and praised Vettel as a true champion via Twitter. He said: "It's very easy for things to be misunderstood so I just wanted to clarify things."Hamilton's only win during the 2013 season came at the Hungarian GP in July, but he still thinks he can challenge Vettel on Sunday. "I definitely haven't given up on the idea of being able to (beat Vettel)," Hamilton said. "We just need a weekend to go our way as it did in Hungary."Hamilton's only win in Japan came at the Fuji Speedway in 2007. Hamilton said the Suzuka circuit presents a unique set of challenges: "In the past when I've been here, you can push, you can be aggressive but it's not very forgiving. If you are off line, or turn in a bit late you can lose position so accuracy is more vital here than at a lot of other tracks." Stay with Wheels24 for the 2013 Japanese GP weekend.
