Featuring more aero... and a halo.

Formula E has unveiled its second-generation racer, set to hit the track in the 2018/19 season.

The futuristic racer, dubbed Gen2, has double the battery capacity and, by extension, twice the range of the current car, spelling an end to the awkward mid-race car-swaps that currently feature.

Along with the bigger, better batteries, the new racer features the 'Halo'. Designed to protect the drivers of 'open-topped' racers from flying debris and awkward head-high impacts, the controversial carbon-fibre component will eventually find its way onto Formula 1 cars.

Halo aside, the new car runs with a much more aggressive aerodynamics package than before. Gone is the conventional rear wing, and in its place is a dramatic split design, sitting above an angular diffuser. There are hints of IndyCar about the side-pods, while the semi-enclosed front wheels should allow for tighter wheel-to-wheel racing.

"This car represents the future of racing," said Formula E Founder and CEO Alejandro Agag.

"When we started Formula E, our goal was to break the mould and challenge the status quo - bringing a revolution to motorsport. This next generation car represents that revolution."

The new car will arrive at a critical juncture for the burgeoning Formula E series. BMW, Nissan, Porsche, Mercedes-Benz and Audi have all committed to the sport from either 2018 or 2019, with many ending their existing motorsports programs to do so. If the racing is good, the new car and heightened manufacturer support could be the making of Alejandro Agag's all-electric brainchild.

"I’m very proud that the FIA has been at the forefront of this car’s development, it’s something new for the Federation, and the project has been a huge success," said the organisation's President Jean Todt.

The Gen2 car will be unveiled in full at the Geneva Motor Show on March 6.
