(from Gordon Murray
Press Release) Gordon Murray Design’s T.25 City Car will make
its first public appearance at the Smith School’s World Forum on
Enterprise and the Environment in Oxford today.
Sir David King, Founding Director of the Smith School of Enterprise
and the Environment said:
“Our transport sector is hugely dependent on fossil fuels and we
need to de-fossilise our economy as quickly as possible. We know
most of the technologies already exist in delivering low carbon
transportation and the T.25 and iStream® manufacturing processes are
clear examples of how the transition can bring new and exciting
The T.25 represents a major breakthrough in city car design in the
areas of weight, footprint, safety, usability and efficiency. Whilst
applying a holistic and fit for purpose approach to the design and
development of the T.25, Gordon Murray Design have taken the
opportunity to incorporate solutions to a multiple of urban mobility
problems into the T.25 design.
A world leading 6 metre turning circle will help with urban
manoeuvring and parking whilst its 1.3 metre width opens any
opportunity for timed lane zones with 2 vehicles travelling and over
taking in one lane. Combining this with the car length, could triple
lane usage at peak times. The T.25’s short length also opens an
opportunity to park end on to the curb and the door opening allows 3
cars to be parked in one parallel parking space.
Gordon Murray Design was established in 2007 to develop an
innovative and disruptive automotive manufacturing technology
trademarked iStream® and the design and prototyping of the T.25 city
car was central to both the development and validation of iStream®.
This manufacturing process is now industrialised including final
factory designs by specialist automotive consultants.
Holger Erker, Managing
Director of IPE Engineering said:
“After a complete and
comprehensive comparison of the process details and seeing the
vehicle prototype build, our conclusion is affirmative that the
innovative vehicle and process design of this project is
outstanding. From our analysis the iStream®process can be positively
qualified as the most promising manufacturing process development in
the car industry of the next decade”
The iStream® assembly process is a complete rethink and redesign of
the traditional manufacturing process and could potentially be the
biggest revolution in high volume manufacture since the Model T.
Development of the process began over 15 years ago and it has
already won the prestigious 2008 ‘Idea of the Year’ award from
Autocar who were given privileged access in order to make their
assessment. The simplified assembly process means that the
manufacturing plant can be designed to be 20% of the size of a
This reduces capital investment in the assembly plant by at least
80%. Yet the flexibility of this assembly process means that the
same factory could be used to manufacture different variants. The
iStream® design process is a complete re-think on high volume
materials, as well as the manufacturing process and will lead to a
significant reduction in full lifecycle CO2.

The T.25 has recently
been seen testing on public roads and has featured in many
publications but the Smith School World Forum is the first public
appearance and Gordon Murray Design are excited to now be able to
release the first images of the car’s interior and seating position.

“We are very privileged to have been asked to show T.25 publicly for
the first time at the World Forum as the aims of our Company are
very much aligned with those of the Smith School and therefore this
