Technology N net: Superbus

Speed : 250 kph

Passengers : 23

The Dutch-built Superbus was shown to the media at Masdar City in Abu Dhabi (Apr 10, 2011). Fully electric and designed to be capable of 250 kph while carrying 23 passengers, it is being pitched as the next-generation solution to the Dubai-Abu Dhabi commute. The high-speed bus that could slash journey times between Abu Dhabi and Dubai to 30 minutes.

Team

Research and development team

The research and development team is headed by the following three persons:

Prof.dr. Wubbo Ockels

First Dutchman in space and now full professor at TU Delft and the Rijksuniversiteit Groningen. At TU Delft he heads the ASSET chair (AeroSpace for Sustainable Engineering and Technology). Within the project he has the role of General Manager

Dr. ing. Antonia Terzi

Italian designer with a Formula 1 background. She used to be the chief aerodynamicist of the BMW-Williams Formula 1 team. Antonia holds the position of Chief Vehicle Designer. Next to that she is assistant professor in the ASSET chair.

Joris Melkert MSc

Aerospace engineer and now assistant professor in the ASSET chair. He has been involved in several aircraft development projects as well in the development of NUNA 3, the fastest solar car on earth. He is in charge of logistics and infrastructure matters.

The Superbus, which is being developed at the Delft University of Technology in Holland (http://home.tudelft.nl/), is on show in Dubai at the UITP Mobility and City Transport Expo - the first time it has been seen outside Europe.

The streamlined midnight-blue vehicle has eight gull-wing doors on each side, can hold 23 passengers plus a driver and was designed to travel on both normal roads and a special high-speed track.

Prof Ockels said his team was about to hold talks about the project with UAE transport officials. They hope to arrange a demonstration run for Dubai's Roads and Transport Authority after the expo ends.

The fully functioning prototype has already reached 140kph in tests, and Prof Ockels said he would be surprised if the electric vehicle had not touched its theoretical cruising speed of 250kph by October.

The team has brought the environmentally friendly Superbus to the UAE because of the interest shown in sustainable transport by the authorities here.

"We always had an interest in the Abu Dhabi-Dubai route. I was here 16 or 18 years ago and have followed the development, and I think here there is an ambition to grow into a sustainable world and a need to introduce proper public transport," Prof Ockels said.

"And the fact that you have quite substantial economic support, that combination is a good opportunity for us.

"During my space flight [on the space shuttle Challenger in 1985], I realised that the Earth is just a big spaceship where the hull is the thin layer of the atmosphere which is protecting us against the dangers of space, because in space you can't live.

"So that gave me the urge to work on sustainability."

The idea for the Superbus was born during a rather more prosaic journey - a commute between the two towns in Holland where he worked as a university professor.

"Delft and Groningen are 200km apart," Prof Ockels said. "On the days I travelled between them it took me fours hours in the morning by train and five hours to go back in the evening. So I had nine hours for 200km and I said, 'this is not right'.

"And then I thought, as a customer, what's the ideal public transport? It needs to be fast but not like a fast train, because I don't live near a station.

"So fast, but I want it to be flexible and use normal roads because, with normal roads, you can access the place where you want to be.

"So I had to think of a combination of high speed and flexibility - and that's a high-speed bus. Then I didn't want it to pollute, so it had to be electrical."

He said he hoped that within five years the first Superbus system would be up and running, adding: "Within 10 years I'd hope we would have a few hundred vehicles."

The Superbus was designed by Italian Antonia Terzi, an ex-Formula One aerodynamicist with the Ferrari and Williams teams. The vehicle incorporates a number of technologies borrowed from Formula One.

She said: "Firstly there's the aerodynamics. Then there's the chassis design and manufacture; it's all in carbon epoxy.

"We have carbon-ceramic brakes, like in Formula One. We have carbon-magnesium wheel rims - only 16kg for each wheel rim, nothing when you consider the vehicle weighs 10 tonnes."

Ms Terzi admitted she was not initially keen to move from the glamour of Formula One to designing a bus.

"Wubbo asked me and I was like, I don't want to design a bus, no, no, no - I come from Formula One!

"But I really liked the concept and the fact that there was nothing - normally every year you start with a baseline for a vehicle and then you develop it, but here there was no baseline.

"It was like a white piece of paper. It was such a wonderful challenge."

The Superbus will remain on show at the expo at the Dubai International Exhibition and Convention Centre until April 14.
