Gordon Murray Design announce 'iSTREAM® CARBON' a revolution in automotive manufacturing

iStream® Carbon is being shown for the first time at the 2015 Tokyo Motor Show and is the chassis technology used for the Yamaha 'Sports Ride Concept' sports car project.

The 'Sports Ride Concept' is an in house Yamaha concept design based on an iStream® Carbon chassis developed at Gordon Murray Design working with the Yamaha team.

iStream® Carbon is the world's first affordable high volume carbon fibre chassis structure bringing Formula One materials and technology within reach of the everyday motorist.

iStream® Carbon sets new standards in the Automotive industry for chassis light weighting, rigidity and safety.

iStream® Carbon is derived directly from Gordon Murray Design's highly successful iStream® Manufacturing System.

iStream® offers manufacturers:

  • A lightweight chassis system without the cost increases associated with all current light weighting technologies.
  • A large reduction in capital investment.
  • A significant reduction in manufacturing energy.
  • New levels of product flexibility from a single platform.
  • New levels of chassis rigidity and durability and corrosion resistance.
  • New levels of safety.

The new system replaces the glass content in iStream® with carbon fibre which offers even more performance for lightweight and rigidity.

Gordon Murray Design Limited has been developing iStream® Carbon for the last 2 years with partners Toray Industries, Innovate UK and ELG, and the process is now fully industrialised.

Unlike any other carbon fibre chassis technology, iStream® Carbon is a fully mechanised system with a cycle time of just 100 seconds. iStream® Carbon is true Formula One racing technology utilising two carbon skins sandwiching a honeycomb core, unlike many expensive handmade supercars which employ monolithic (single skin carbon panels).

The low cost investment and piece part cost of iStream® Carbon components will enable it to be used in sub premium market segments.

iStream® and iStream® Carbon can cater with annual production volumes between 1,000 and 350,000 units per year at a cycle time of 100 seconds and can reduce capital investment by up to 80% reducing manufacturing energy by up to 60% whilst offering new levels of rigidity, corrosion resistance, safety, durability and low cost light weighting.

iStream® and iStream® Carbon represent a major step change in automotive manufacturing.

Gordon Murray Design Chairman - Professor Gordon Murray said:

"Light weighting is the final frontier in the automotive industry fight to lower emissions. There have been great strides forward in engine design, electrical control systems, tyre design and transmission technology, but we are now experiencing a plateau in the advance of technology where the law of diminishing returns comes into play. A step change in vehicle weight to enable downsizing of powertrain and components is all we have left in the armoury. Light weighting is important for internal combustion engined cars, but even more important for hybrids and electric vehicles.

iStream® and iStream® Carbon is that step change and is the world's first affordable, high volume bonded composite structure which sets new standards of safety, rigidity and durability.

iStream® delivers performance through lightweight.

iStream® Carbon does not replace our existing iStream® manufacturing process, it sits alongside our standard system to open up more market segments for us. We are currently working on 7 vehicles using our original iStream® technology”.

Editors Notes

  • Yamaha Motor Company Limited is a Japanese motorized vehicle-producing company. Yamaha Motor Company (headquarters is located in Iwata,Shizuoka) is a sister company of Yamaha Corporation who shares its brands and corporate philosophy. Along with expanding Yamaha Corporation into the world's biggest piano maker, then Yamaha CEO Genichi Kawakami took Yamaha into the field of motorized vehicles on July 1, 1955. The company's intensive research into metal alloys for use in acoustic pianos had given Yamaha wide knowledge of the making of lightweight, yet sturdy and reliable metal constructions. This knowledge was easily applied to the making of metal frames and motor parts for motorcycles. Yamaha Motor produces motorcycles, all-terrain vehicles, boats, marine engines including outboards, automobile engines, personal watercraft and snowmobiles. For more information please visit

  • The iStream® assembly process is a complete rethink and redesign of the traditional automotive 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 ‘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 conventional factory. This could reduce capital investment in the assembly plant by approximately 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.
