The Andretti Autosport driver holds a 24-point lead over nearest championship rival Nick Cassidy and is 20 points further ahead of Mitch Evans, with only 58 points available this weekend in London.
Dennis has had considerable success at the unique indoor/outdoor ExCeL London venue over the last two years, claiming one win in both seasons at the track when he drove a BMW-powered Gen2 machine.
But the Briton says that previous form will count for nothing this weekend when he drives the Porsche-powered Gen3 machine as he aims to take his maiden Formula E title.
“All of us are on a pretty good run of form, we’re not in this position by chance, we’re all driving well, we’re all performing at a really high level,” he said.
“This track has suited what I’d had in the past, the BMW powertrain was obviously working extremely well here.
“I don’t come here into this race expecting to do what I did then, it’s a complete reset. These guys know how to drive, I just had a better car than them the last couple of years at this track.
“I’ll take it a session at a time but I’m feeling confident, I’m pretty relaxed and I’m just looking forward to jumping back in the car. If it’s meant to be it will be and if not, then that’s it.”
