All-electric single-seater motor racing is taking place in London's Battersea Park this weekend. Here's our guide to what it's all about

The inaugural FIA Formula E Championship reaches a climax this weekend around a temporary circuit laid out in Battersea Park, south London.

After events in China, Malaysia, Uruguay, Argentina, Miami, Long Beach, Monaco, Germany and Russia, the series for electric single-seat racers culminates with a brace of hour-long races, one apiece on Saturday and Sunday. Here’s what’s in store this weekend.

Battle for the titles

With two points-scoring races over two days, no fewer than six drivers can mathematically clinch the title. However, it is realistically between three former Formula 1 racers: Nelson Piquet Jr, Lucas di Grassi and Sébastien Buemi. Nicolas Prost, Jerome d’Ambrosio and Britain's Sam Bird are the outsiders. The teams' classification, meanwhile, is topped by e.dams-Renault, which enjoys a commanding lead over its closest pursuer, Audi Sport Abt.

Fanboost

Fans can earn their favourite driver a power boost by voting for them prior to the race. The three drivers with the most votes will each receive one five-second ‘power boost’ per car, temporarily increasing their car’s power from 202.5bhp to 243bhp. The recipients of the extra power are revealed prior to each race. In the build-up to the race, championship leader Piquet Jr had the edge in the Fanboost poll.

Tough track

The course that’s been laid out on the Battersea Park perimeter roads measures 1.81 miles and manages to squeeze 17 corners into that space. The drivers are expecting to be extremely busy during each of the 29-lap races; heavy braking zones, tight chicanes, a significant crown on the road surface and unyielding walls will place a premium on smooth, intelligent driving.

Busy weekend

For the first time this season, the Formula E drivers will race twice over a weekend. There’s a fair amount of track time to enable them to learn the challenges of the Battersea Park circuit. There are two non-qualifying practice sessions early on Saturday morning, followed by an hour of qualifying starting at midday. The qualifying session is a straight fight for the fastest lap time. The session lasts for 40 minutes of track time and drivers are divided into four groups of five cars, with each group having 10 minutes to set their best time. The race starts at 4.04pm. Sunday’s timetable follows an identical format.

The tech

The car, as tested by Autocar earlier this year, is built by Spark Racing Technologies from a chassis constructed by Dallara. The battery pack is developed by Williams Advanced Engineering, part of the same company as the Formula 1 team, and the powertrain is the work of McLaren Electronic Systems. The car produces a maximum of 270bhp in qualifying trim and around 200bhp in race mode.

Changing cars

By far the most controversial aspect of Formula E has been the mid-race car changes, necessary because the current technology cannot provide sufficient energy to last for an hour-long race. So each driver has to pull into the pits and jump into a fully charged machine. Series chiefs aim to eradicate this system in future seasons, when the technology has progressed to enable a car to complete an hour-long race.

Next season

Formula E teams and officials are already ramping up for season two, when the championship’s technical rules are being relaxed. Instead of using the stock Spark-Renault SRT_01E package that’s been mandated in season one, teams will be free to develop their own powertrain and battery technology. The aim is for this to filter into the electric road cars. Eight manufacturers have committed to the 2015-2016 season.

Stars of tomorrow

On the undercard of the main championship, the Formula E School Series pitches teams of pupils from local schools against each other in 20-minute race using identical battery-powered kit cars. It’s not all about speed; the winning participants also have to display good energy efficiency. The idea is that students inspired by the competition will then transfer their interest to Formula Student, in which they will get to develop and build their own racing machine.

Tickets

Admission to watch the race costs from £22.40, which allows access into one of three designated standing zones. There are no seated grandstands at the event due to landscape and space around the park. Check out the Formula E website for further information.

No ear splitting noise, no exhaust fumes, no fancy circuits built with oil billions in the desert, just up close racing on city streets. That's the future and I think it's great. I don't mind the car switching at all because hey, that's what they did in the early days of Formula One and this are early days for electric racers.

26 June 2015
I'll be there tomorrow - looking forward to it.

Just watched the qualifying and apart from the fact they sound like a mix of milk float and radio controlled car I was quite impressed. This race may be a bit boring, though, that track is way too narrow for racing.

27 June 2015
It is extraordinarily narrow and the barriers/fences look very unforgiving. The race will be like an automotive cage fight.

Lots of people here, everybody seems to be enjoying things so far.

I take it back. Just watched the race on TV and it was great, one of the best I've seen in a while and some great overtakes.
