Gordon Murray Design to licence iStream lightweight seat

  • Transcal will licence GMD seat, which weighs 30% less than standard unit
  • Automotive OEM and bespoke projects are new seat targets for Transcal
  • Weight saving, elegant design and scalability core to Transcal decision

Gordon Murray Design has entered a technology licencing agreement with Transcal Limited to manufacture the iStream® lightweight automotive seat. The new agreement will cover the current seat design, codenamed IS-001. This innovative unit boasts a significant 30% weight saving when compared to a conventional modern seat.

The IS-001 seat licensed by Transcal, a leading automotive supplier of innovative interiors since 1980, will be the world’s first implementation of the iStream lightweight seat. Gordon Murray Design is exploring further automotive and non-automotive designs and applications for the seat.

Transcal, with the support of Gordon Murray Design, plans to release the seat for volume production in the first quarter of 2020. Fully-trimmed units will be available for OEM production and also to custom builders for bespoke applications.

Professor Gordon Murray CBE, Chairman of Gordon Murray Design, said: “We welcome the opportunity to work with Transcal, a business that shares our focus on a more efficient future for the automotive sector and pushing boundaries at every opportunity. The iStream lightweight automotive seat represents a seismic shift in this sector – its innovative construction helps to deliver both economic and environmental benefits.”

The iStream lightweight seat will be on display later this year at:

  • Cenex Low Carbon Vehicle event - UK: 4-5 September 2019 (to be confirmed)
  • IAA Frankfurt – Germany: 10-15 September 2019
  • SEMA – Las Vegas, US: 5-8 November 2019

iStream lightweight seat

The iStream lightweight seat is the product of a research-based project, part-funded through the Innovate UK framework – the Manufacturability of Advanced Passenger Seats (MAPS) – with the objective to develop lightweight automotive seat structures and production methods.

The newly-developed seat can be modified to suit all types of vehicle. Its advanced composite panels and tubular frame construction dramatically reduces structural weight, while maintaining the high-volume, low-cost benefits of Gordon Murray Design’s original iStream technology.

Key advantages of the iStream lightweight seat include:

  • Lightweight composite structure (sub 12kg)
  • 30% weight saving vs conventional modern seat
  • Suitable for high- and low-volume applications
  • Ultra-low tooling and development costs
  • Simple, high-speed assembly
  • Low part count
  • Competitive piece cost
  • Satisfies all applicable European automotive requirements (UN ECE), including luggage retention requirements
  • Can achieve low seating position
  • Anti-submarining design
  • Full four-way adjustment

About iStream

Rather than the traditional method of combining hundreds of panels of stamped metal, iStream uses tubular metal with 10 – 15 structural composite panels. iStream Superlight® is the ultimate automotive lightweighting technology as it maximises the iStream approach by using cored honeycomb carbon fibre composite and an aluminium frame to save almost 50% in weight against a standard stamped metal chassis.

iStream is an acronym for iS = Stabilised; T = Tube; R = Reinforced; E = Exo-frame; A = Advanced; M = Manufacturing.
