Flying taxi startup Lilium nabs $90m investment boost

Sep 06, 2017

On-demand air taxis just got one step closer to becoming a reality. Lilium, the German startup whose flying taxis can go from vertical takeoff to horizontal flight, has announced $90m (£69.59m) in funding, a big leap from the $10m it had already raised from London VC Atomico and Freigeist. The latest round of funding was raised by Tencent, LGT, Atomico and Obvious Ventures.

Lilium remains tight-lipped on timelines for the commercial launch of its flying taxi, but chief operating officer Remo Gerber says the money will let the firm focus all its “time and efforts on a five-seater version of the jet and build a prototype for the certification process”.

The company was founded two years ago. What seemed like a fantastical idea at the time – launching a fleet of on-demand, 300km/h, zero-emission flying cabs into the skies – now feels almost realistic.

Lilium has already been working with regulators to ease the path for aviation certification. “We’re not waiting for the very last day to find out if we passed or failed,” Gerber says. “Regulators work with you very closely,” he adds, explaining that many elements of the novel jet taxi design might speed up regulatory approval. For instance, the electric, carbon fibre vehicle has fewer parts than an ordinary aircraft, so there are fewer parts to certify.

“If you look at the aircraft, there is no tail rudder,” Gerber says. This is thanks to its three electric engines, which in turn have just one moving part each. There are also 12 identical flaps that are used to exact direction and stability. “You are not looking at a variety of different flaps on parts of a wing; you have several components that are repeated,” Gerber says. Of course, he adds, there are no shortcuts in aviation. “It’s a strict process, and rightly so.”

Earlier this year the company completed a two-seater test-launch, confounding those who feel its flying taxi dreams remain some way off. “This is a hardcore engineering effort and we need the very best engineers out there," Gerber says. "There are still some very interesting engineering challenges to be solved; on the other hand, once you have a proof of concept the rest takes off from a physics perspective. We have already shown it is possible. The challenges where physics is involved don’t change as such – they just get bigger.”

Those challenges, though significant, would deliver something impressive: a zero emission, 300km/h vehicle (a 19km trip from Manhattan to JFK Airport could take five minutes, the company claims) that cuts out congestion and plugs frustrating holes in regional and national infrastructure – for the cost of land travel. Lilium plans to keep the cost down through ride sharing and fuel efficiency. Thanks to a lack of air traffic, Lilium claims it would also be able to complete four or five journeys in the same time it would take a regular cab to complete one.

The issue of space and charging infrastructure also isn’t insurmountable, according to Gerber. “It could land on a shopping mall, such as Westfield in Shepherd’s Bush or east London; or the top deck of a car park could become a landing deck. The space you need isn’t actually that huge so it’s entirely possible.”

Gerber envisions a distributed network of London ports. One located at City Airport or the Isle of Dogs would allow people to pick up on the many connections in those areas to continue their journey. Lilium doesn’t see itself as competing with hubs such as City, but complementing them. It could, for instance, help plug gaps in infrastructure left by HS2, which is only connecting major hubs.

Before any of that, Lilium will have to convince the public to hop aboard its eerily quiet, affordable urban jets. “It’s too early to have that conversation,” Gerber says. “At this point there are two types of people. Those that say, ‘Mmm... that’s interesting, but I’d like a few people to do it before me’. And others that jump on it. It will have to go through commercial aircraft certification – that’s the same regulator that tells you it’s safe to fly with British Airways. From our side, there’s a lot more work to be done."
