Dunlop has developed tyres for the new Opel Monza Concept car, revealed at the 65th International Motor Show in Frankfurt this week. Dunlop says that work on the concept tyre, in size 245/35R21, began in early 2013 and underwent a number of stages in collaboration with Opel to meet the car manufacturer’s expectations. The design features the same sleek lines found on the Monza Concept, enhancing the car’s overall look through the tyres and onto the ground.
“Dunlop and Opel design teams worked on the design and development of the tyre to ensure the tread matched the sleek shape of the car perfectly”, explains Helmut Fehl from Dunlop’s advanced design and development centre in Hanau, Germany. “Every detail of the tyre was discussed, evaluated and designed to meet the highest standards and expectations of the Opel team.”
Hankook is aiming to innovate with premieres in the fields of green tyres, performance, safety and premium original equipment, award-winning hybrids design-concepts as well as a new generation of airless, almost entirely recyclable tyres at the Korean company’s IAA stand. The 65th IAA, runs from 12 – 22 September 2013 in Frankfurt, Germany.
Bridgestone has announced its dual strategic intentions for its stand at the 65th International Motor Show for Cars in Frankfurt. The manufacturer will divide its stand between a “current zone” with its “Everywhere” brand marketing platform and premium tyre range, and a “future zone”, which will focus on concept tyres, including one made with “100 per cent sustainable material”. The show takes place on 10-22 September, and Bridgestone Europe’s 320m² stand will be located at D03 in Hall 8.
The Citroën Hybrid Air has enjoyed its world premiere at this year’s Geneva Motor Show, and the technology is expected to be in production by 2016. Based on a petrol engine and hydraulic components (engine and pump) but no battery, the French car maker states that Hybrid Air technology combines ground-breaking performance with maximum accessibility. Citroën claims the Hybrid Air demonstrator can achieve 2.9 litres of fuel per 100 kilometres, with carbon dioxide emissions capped at 68 grammes per kilometre; in comparison the Citroën C3, at the same power, uses 4.5 litres of fuel for 100 kilometres and emits 104 grammes of carbon dioxide per kilometre.
In the future we may return to the past, at least when it comes to tyre dimensions – tomorrow’s tyres may take their cues from the large diameter, thin tyres of the 1920s and 1930s. By giving tyres a larger vertical diameter and increasing their internal air pressure, it is possible to limit changes in the shape of the contact patch, the section of the tyre that comes in contact with the road. Furthermore, by optimising the structure of tyres created using this technology and using appropriate materials, a significantly lower rolling resistance coefficient can be achieved. And when these tyres are narrower than those typically used today, air resistance is also decreased.
Bridgestone Corporation’s 2012 Mid-Term Management Plan (MTP2012) leaves little scope for misinterpreting the company’s aim. In its latest plan, announced 18 October, the Japanese firm states that its ultimate goal is to become the “undisputed world number one tyre and rubber company in both name and reality.” The plan covers the five years from the start of 2013 to the end of 2017, and Bridgestone says MTP2012 reflects “changes in the operating environment” since the formulation of MTP2011.”
Yokohama Rubber Co., Ltd. has announced its participation in Tokyo Motor Show 2011, which will run from 30 November to 11 December (open to the general public from 3 December), at Tokyo Big Sight in Koto-ku, Tokyo. Yokohama will present some of its ideas, technology and activities including the firm's BluEarth eco tyre. Not only the BluEarth branded tyre series will be on show, but also other tyres developed based on the BluEarth concept. The company's latest environmental technology will also be explained, including the "nano bland compound" containing orange oil and the Airtex Advanced liner, which can substantially mitigate natural air leakage.
Last month’s IAA motor show in Germany featured numerous concept vehicles. Concept tyres also made an appearance, including Hankook’s new concept for electric and hybrid vehicles, the Kinergy Eco EV. Described by the manufacturer as a “further development” of its spring 2011-launched Kinergy Eco, the tyre shown at the IAA featured tweaked contours to reduce air drag and rolling resistance below that of its production counterpart. Hankook also notes that the Kinergy Eco EV’s 155/70 R 19 dimensions give it an “unusually large” diameter (700mm) compared to its width.
Industrial design associates, Dolton & Dex, has announced the launch of the world's first concept tyre design service. According to reports, director Bob Dolton has spent many years working on concept tyres for a number of OEMs. "More often than not, it is an area of the vehicle that designers feel they have a lack of control over," said Dolton.
Bridgestone has revealed that it will focus on its future strategy in ecology, innovation and reliability on its 284m² stand in Hall 8 at the 2011 IAA show in Frankfurt. The stand will be split into three sections, with the left devoted to ecological features, the middle and “innovation zone” and the right focused on reliability.
According to Michelin, a special power train requires a special tyre. And it claims to have embraced this philosophy when designing its first concept tyre for electric vehicles. Known as the EV, the Michelin concept tyre is intended to provide a range of benefits that include increasing the vehicle’s range between charges or reducing battery size to optimise use of interior space. At the same time, the tyre is said to enhance driving safety and deliver superior longevity. Furthermore, says Michelin, the prototype tyre offers a quiet ride that is ideally suited to a relatively noise-free power source.
Copenhagen is hosting the United Nations Climate Change Conference, and present at the event will be the world's first concept demonstration tyres made with BioIsoprene technology. This breakthrough substance, which replaces a petrochemically produced ingredient used in the manufacture of synthetic rubber with renewable biomass, made its debut in the Danish city in early December. Several tyres, produced in collaboration between Goodyear and industrial biotechnology company Genencor, have been shipped to Copenhagen. One will make appearances at several events during the conference. Others will be displayed in several locations, including at Copenhagen International Airport’s departure lounge through to December 21.
Goodyear has been using high-strength Kevlar in its products for some years now, and recently the company highlighted the advances made using the fibres developed by the scientists at DuPont. The US based tyre major points out that tyre reinforcement was the initial application for Kevlar more than 40 years ago, and today the product is used across the company’s range. The material property advantages of Kevlar are extensively used in developing products that address the issues of ride and comfort, handling, thermal and flame resistance, reduced tyre weight and road noise.
Bridgestone has used the opportunity afforded by the Geneva Motor Show to feature road safety exhibits alongside its latest products. 2007 was the third year for the company’s Think Before You Drive road safety campaign, and the year’s activities have been reviewed in detail; these include the findings from the approximately 70,000 tyre safety checks conducted throughout Europe between 2005 and 2007. This joint Bridgestone / FIA Foundation (Fédération Internationale de l’Automobile) initiative is aimed at reducing road accidents by promoting simple safety procedures, including correct tyre care. The tyre safety check findings are projected to illustrate how tyre maintenance can contribute to what Bridgestone calls a ‘safer and greener’ society.
Land Rover recently displayed its vision of tomorrow’s 4×4 vehicle at the Detroit Auto Show. Called the LRX, the concept vehicle pointed towards the development of lighter, hybrid powered vehicles – and low rolling resistance 245/45 R 20 tyres, specially designed and supplied by Continental.
“We developed the tyre design in close contact with the Land Rover Design Group,” commented Conti designer Ulrich Behr. “We focused on making a tyre with low rolling resistance that is a symbiosis of design elements from off-road and sports tyres. And the 20-inch size is in tune with the vehicle size and appearance. The LRX logo was integrated in the flowing tread elements to accentuate the exclusive nature of the experimental vehicle.”
