completely new tech’s first use will be on the completely new Yamaha sports car concept

completely new iStream manufacturing process to use completely new, radical lightweight carbon fibre techniques. Yahama sports car first to use tech

The Yamaha Sports Ride Concept sports car unveiled at the Tokyo motor show will be underpinned by a revolutionary completely new carbonfibre chassis designed by McLaren F1 designer Gordon Murray, Autocar can reveal.

While Yamaha kept the external design of the vehicle a secret prior to today’s launch, Murray revealed in which in which sits on the radical, all-completely new carbonfibre structure called iStream Carbon. in which’s claimed in which “sets completely new standards for chassis light weighting, rigidity in addition to safety”.

Murray described the technology used to develop 
the system as a “step change” in addition to said in which had the potential 
to fundamentally change 
car creating.

“Light weighting will be the final frontier inside automotive industry fight to lower emissions,” he said. “There have been great strides forward in engine design, electrical control systems, tyre design in addition to transmission technology. however we are currently experiencing a plateau inside advance of technology, where the law of diminishing returns comes into play.

“A step change in vehicle weight to enable downsizing 
of powertrain in addition to components will be all we have left inside armoury. Light weighting will be important for internal combustion-engined cars however even more important for hybrids in addition to electric vehicles.”

The system will be derived coming from Gordon Murray Design’s iStream manufacturing process however replaces the glassfibre content with carbonfibre. in which has been developed in conjunction with Japanese firm Toray, for whom Murray designed the Teewave sports car in 2011, in addition to sandwiches a honeycomb paper core with two carbonfibre skins.

Murray confirmed in which iStream Carbon doesn’t replace the original system. He said: “We are currently working on seven vehicles using our original iStream technology.”

As well as its weight, strength in addition to safety benefits, in which will be notable for being fast in addition to cheap to produce. Murray claims to have developed a 
fully mechanised system 
that has a cycle time for each 
panel of just 100 seconds.

Murray did not disclose the weight of the Yamaha Sports Ride Concept, however in which will be believed to be significantly lighter than 900kg. The cost of producing a chassis will be closely linked to the volume of cars being produced in addition to the up-front investment required, however Murray said the system can be employed profitably for production volumes of between 1000 in addition to 350,000 cars. As such, in which will be believed the Yamaha Sports Ride Concept could be priced competitively against the likes of the Lotus Elise.

“I genuinely believe in which car could open up a completely new sector,” said Murray. “If you look at the [Mazda] MX-5, in which’s great fun in addition to a nice roadster, however in which’s not an out-in addition to-out sports car. The Toyota GT86 will be great however relatively heavy. in which’s not a huge revolution. Then there are cars like the Alfa 4C, which will be rear mid-engined however which costs nearly £60,000. I believe we could have something genuinely rule-breaking.”

Asked whether his first confirmed iStream client, 
TVR, could be using the carbonfibre technology, Murray said: “Because of the secrecy with which in which has been developed, the team at TVR haven’t been aware of in which until currently, so in which will be not part of their plans. however, in time, in which will be perfectly possible.”

Although neither Murray 
nor Yamaha could comment 
on the powertrain inside 
Sports Ride Concept, in which could combine Murray’s chassis with an uprated variation of the 1.0-litre three-cylinder engine in which was mooted for its city car design, the Yamaha Motiv, which was first shown in Tokyo two years ago.

in which engine was tipped to produce 70-80bhp, however uprated beyond 100bhp in an entry-level form, in which could be likely to give the vehicle a power-to-weight ratio in excess of 140bhp per tonne, which will be around in which of an Elise.
