Former Formula One world champion Nico Rosberg treated fans at the Berlin E-Prix with the first public demonstration of the futuristic Gen 2 car. It will be raced in the all-electric Formula E series for its fifth season, which starts later this year.

Rosberg took the car around the streets of Berlin -- from the Brandenburg Gate to Checkpoint Charlie -- and even put it through its paces at Tempelhof Airport circuit.

Formula E says the Gen2 car "boasts a futuristic new-look for Formula E, but also shows a clear jump in performance over a race distance and almost double the engine storage capacity."

"It is a huge step in technology and innovation," Rosberg told CNN's Superchaged. "It was exciting to drive through the city -- through my capital city -- past the landmarks, and I did a donut as well in the middle of the city, so that was cool."

Since retiring in 2016, Rosberg has become an investor and shareholder in Formula E.

It was Rosberg's first public appearance since winning the 2016 Abu Dhabi Grand Prix with Mercedes -- which will be joining the Formula E grid for the 2019-20 season, adding to speculation that Rosberg could be returning to the track -- but he was quick to shut down rumors.

Viewers will be able to watch the Gen2's official debut when the fifth Formula E season begins in Saudi Arabia later this year.
