and if somebody is right behind you, it means they will likely overtake you. then you will have to overtake him again using more power. so it is like playing chase while driving. the other striking change for season five is the look of the cars. and let's face it. it looks too much like the batmobile not to fall completely in love with. with the combined look and sound, it does feel a little like driving into the future. wow. and new to formula e this year is the market leader for electric consumer cars. we were able to use a lot of our knowledge in the production side to come racing.

of course racing will help us develop future technologies, but we really wanted to demonstrate what was capable today. see how much of this tech the commercial cars have packing. now i could drive around the car park in a road car for this bit, but... has someone gone in the wall and the exit... this season jaguar launched the i—pace e—trophy, racing on the same city circuits, and well, it would be rude not to, really, wouldn't it? this i—pace may have been stripped down for racing but it is the same basic car you can drive out of a showroom. the road car is focused on comfort and driver ability to use it every day, whereas this is a pure race car. and lessons learned on race day are vital for future innovation. which is why so many

carmakers want in. what we hope is that season one, we focus on development of the race car, and then season two, three, beyond, we can bring what we learn from the race, or the race track, back into the road car. the same engineers who developed the i3 and i8 powertrains have developed our motor on the formula e car, so it is really directly related. like their formula e siblings, these cars are quick and quiet. you said there is no frills, you can hear the noise of the track going under the car. you are able to hear a lot more of what the tyres are doing and almost what the brakes are doing as well, so it adds an extra dimension to it. and after spending a day on the track here in berlin, i am going to look at electric road cars with a lot more respect in future.

wow. that was kate russell. and that was amazing. now, being only five years old, formula e is still relatively unknown to some. and being born in an age when formula one is arguably the most well—known motorsport and with most of us buried in our mobile phones these days, it could be difficult to attract new fans. however, they are using your phone in theirfavour. omar mehtab takes a look at how that has been working out. youtube, twitter, ghost racing, and the formula e app. these are the four apps that formula e are using to try and reach a new younger audience online. so how are they doing that? let's start with youtube. we all know how massively popular it is, with over 2 billion monthly logged—in users checking out all kinds of content. that's a lot of new potential fans. and so formula e want a piece of the action. at the beginning of the season, i tagged along to watch formula e's

new live show, voltage, being streamed. it's their attempt to introduce a younger audience to the relatively new sport. famous youtubers present the show and give live race commentary. a lot of young people don'tjust sit and watch one thing. they'll watch something on their phone and watch something on their tv at the same time. and that's what i think makes formula e innovative is, as a sport, they don'tjust go take that, that's what you're given. they listen to the audience and say, right, what do you want to see more of, you know, do you want to see in the driver's cabin, or do you want to see — hear — more from the guests? well, that was the idea. but the show was canned halfway through the season. next up — fanboost. before a race fans can vote for the favourite driver via twitter or the formula e app. the five drivers with the most votes get a five second power boost, which could be crucial to victory in a really tight race. but not everyone is a fan of fanboost. when kate asked online what you thought of it, some of you thought it was ok, but the majority of you thought

it was a popularity contest. i mean,, this person's only tweets are to vote for one driver. so is it subject to abuse? should fans have this much input in a race? so let's finish up with probably my favourite out of all of them and what i feel is the most engaging, ghost racing. fansjoin in using the smart phone or tablet and race against the drivers in real—time — as the e—prix is taking place. now this is something that hasn't been done before. you can't go and race live with other drivers in any other sport. you just have to have pretty good wi—fi at home to do with us. that's the only thing you need. we equip the race cars with a gps decoder to so we know exactly where they are and then we ingest the data from the race cars and the scenery and we ingest you as the ghost racer into that live cgi feed. our signal, the live cgi feed is faster than broadcast, because broadcast generally has

a satellite and we're online. so there is no latency. although formula e is hoping this will be enough to attract new young fans, building a following online isn't as easy as it seems. this is brian hamby, otherwise known as the gaming terroriser, who knows a thing or two about hitting the right notes online. the best tool in youtube is your community. if you ignore them you're not going to know what they want. so when you're trying to just, you know, let's just pay to get these people to come on, and then it's going to work — it's not. it's not going to work. kids now are not stupid, they're not dumb. they can tell when things are being pushed down your throat. natural promotion works so much better than an obvious brand integration. who is coming in quick? while formula e's attempts to connect with the new audience haven't exactly hit home, the sheer number of potential fans online means you can bet

they will keep on trying and trying. back in berlin, the e—prix is also home to the first green tech festival, founded by former fi world champion nico rosberg. one thing that remains is my passion for innovation and innovative technologies. that's been the same in formula one. and i'm finding it now in these sustainable technologies, these green. i'm so passionate about the innovation, the pioneering that's happening there. on show here are some greener ways to travel. like this fully electric ship that can travel up to 100 nautical miles on a single charge. but some things are just, well, conceptual, to say the least. this airbus drone is supposed to lift cars out of traffic and drop drivers to their destination. they'll have a range of 30 miles.

but it may take more than these to solve some of the pollution problems that are out there. fossilfuelled cars, bikes, and buses are turning some of india's teaming cities into snarled up and smoking mega—jams. in fact, according to greenpeace, 22 of the world's most polluted cities are in india. now, flogging electric tech to india is proving a tough sell. but inroads are being made. and david reed has taken to india's streets to find out how electric four, three, and two wheelers are having an impact. it's so nice to be back in mumbai. it's always on the move. an outfit called glyd, which is associated with the indian car manufacturer mahindra, has just launched an uber—style car service. and the entire fleet is electric. i met up with a regular customer.

it's absolutely fantastic. just about anything that you want in the car is there. there are tv screens. yes, you have in car entertainment available. in flight entertainment. you have wi—fi, you have video conferencing facility available in the car. it's like your office on wheels. so why electric? the fact that our cities aren't exactly low on pollution means that every vehicle running on petrol or diesel adds to that pollution. would you ever buy an electric car? i would love to. the only challenge here really is infrastructure around. which means you don't have enough chargers, charging points. glyd's a good mobile showroom for mahindra's cars. they're a tough sell because of the recharging issue and price, but what about other vehicles? in bangalore, two college buddies with a passion for electric have created a high—end scooter.

and boy does it scoot. wow. now that is really fast. it is the fastest scooter in the entire sector. you didn't want to just make something that would cater to people's ethical consumer choices, you wanted to do something really attractive. when you walk in as a customer to the showroom you don't go in and say, hey, what is the smallest, least powerful vehicle i can buy out here, right? because the country needs me to do that. you willjust buy something that's absolutely fun. the weight id pushed to the centre so it rides more like a motorbike. it's as fast as they dare make it. they've even throttled back the power. why is that? it was just too dangerous? too dangerous to handle, yeah. if you give complete power it's about seven kilowatts of power which you can squeeze out of this motor. and that could be dangerous for a regular individual. obviously one drawback with electric vehicles is that if you'e having to recharge them two hours a day that's two hours where you're not working and not earning any money.

however, someone has come up with a great idea. i'm running low onjuice. i think you can help, yeah? forget hours of recharging, this pitstop takes one minute. we open it up, take the battery out. people now have vehicles without the batteries. and they use battery as a service. they do 50 kilometres, they pay for 50, they do 100 kilometres, they pay for 100. and so they don't own the batteries, they don't have to manage it. the whole thing is taken care of. on four, two, even three wheels, india's eclectic electric is taking shape. david reed on the road in india. that's it from us for now. don't forget, if you want us we're always there for you on instagram, youtube, facebook, and twitter. we live @bbcclick. thanks for watching.

and we'll see you soon. hello there. the atmosphere on friday was in an extremely lively mood. a lot of rain for some of us, thunder and lightning, and even reports of one or two funnel clouds. these pictures came from somerset. this certainly looks like a funnel cloud. a funnel cloud is very similar to a tornado, itjust doesn't touch the ground. this is the radar picture from friday evening. showers and thunderstorms developed across the west country, south—east wales, drifted up into the midlands. still some hefty showers around through the first part of saturday morning. the thunder and lightning risk much lower at this stage. outbreaks of persistent

rain drifting into southern scotland, northern ireland, certainly affecting northern england and there's some very windy weather down towards the south. it all comes courtesy of this, an area of low pressure, only slowly drifting north through the day ahead. it is going to be unusually windy. the wettest of the weather across eastern and southern scotland, parts of northern england, midlands and east anglia. away from this area some spells of sunshine but also some spells of sunshine but also some showers some of which could be on the heavy side. wendy especially across southern and eastern parts of england where wind gusts could touch 50 miles per hour and that could have an impact on some outdoor events. temperatures are struggling, 12- 18 events. temperatures are struggling, 12— 18 degrees at best. through saturday night, the low pressure spins away to the north—east. the rain will tend to ease. more dry weather. clear spells and under

those clear spells it will turn chilly in one or two places and as the winds fall lighter, the odd patch of mist around as well. sunday is looking like a calmer day. still low pressure in charge some of the showers heavy and possibly thundery. most numerous across parts of scotland, northern ireland, wales and the western side of england. went lighter, particularly down towards the south and it is going to feel a little bit warmer. temperatures of 50 degrees in aberdeen. 19 degrees in london. it does state generally unsettled through the coming weeks. outbreaks of rain at times and for a while at least it will turn very cool indeed.
