There are over 25 million legally registered vehicles on the UK’s roads today. Car manufacturers supply the basic tools that are required to perform the task of changing a wheel with every new car; these tools should be sufficient to complete the task successfully but is this really the case? Research suggests that people are reluctant to perform this task themselves.
Flat Tyres were the AA’s 3rd highest reason for call-out in 2005, beaten only by flat or faulty batteries and Lost keys.

Several user centered analyses were performed with volunteers who matched our key user profiles most closely. Existing products available for purchase were used. Many problems were highlighted in particular:
•  Safety, low posture is often required, particularly in removing wheel studs and jacking the car. If the flat is on the drivers sided, the task must be performed in the road as traffic passes. This posture hides the user from passing traffic and also makes it hard for the user to see the traffic approaching. This problem is increased at night.
•  Visibility of tools is poor at night. Existing tools tend to be black or grey in colour.
•  Clear instructions required, particularly for those who have never performed the task before. They serve to increase the users confidence in completing the task successfully and safely.
•  Psychological issues were also a key factor, many users remarked that they fear of failure would likely prevent them even attempting the task.

In every case we found that it was not possible to complete the task using the tools provided by the car manufacturer, a telescopic wrench was needed to increase the torque applied to the wheel studs.

The design concept behind the product changes the paradigm of how the most problematic task of changing a flat tyre is performed. The product minimizes the steps of changing a flat tyre by undoing the 4 studs of a wheel instead of undoing individually, using the motion force of the car.

• Utilizes the weight and motion of the car to release the 4studs, reducing required effort
• Does not rely on physical strength of user
• Improves road safety in reducing time spent in path of traffic

CONCLUSION

The final developed product is an innovative solution to the problems witnessed when changing a wheel. By loosening all four studs simultaneously, using the forces generated by the turning of the car wheel, the task becomes less demanding for the user while also reducing the time taken.

Adam explanations about A.R.C :

The ‘A.R.C’ (Amphibious Rescue Craft) is a rugged all terrain vehicle that can be used to deliver vital aid and supplies anywhere required including flooded areas which are inaccessible to most other vehicles. Variable height ground clearance combined with large wheels and all terrain tyres provide excellent off road capabilities, whilst a boat hull and retractable wheels enable the A.R.C to plane at high speeds across water with minimal friction and uncompromised performance.

The high output diesel engine powers the wheels when on land and the water jet propulsion system when waterborne which can deliver up to one tonne of thrust. Once landed at its destination, the A.R.C uses an on-board crane (known as a ‘Multilift’ system) to rapidly deploy a supply unit containing anything from medicine or food to a water purification system. The water filtration units can be deployed at the site of a mass flood and used to purify contaminated flood water, returning it to life-saving drinking water which is otherwise scarce in flooded third world environments.

Supply units can also be opened to form mobile shelters for distribution of supplies or temporary living quarters/command centres etc. An unfoldable canopy marked with an ID symbol and number (e.g. Red Cross, Supply Unit number etc.) provides shelter from the rain and can be easily identified by passing rescue helicopters. The name A.R.C not only stands for Amphibious Rescue Craft but also identifies with Noah’s Arc which was believed to have been used as rescue / refuge craft during a mass flood.

NUVU: RESHAPING THE CITY

Within just a few years, cities all over the world will be at near bursting point. If mankind wants to retain the level of personal mobility it currently enjoys – and if the city is to survive – the only way forward is for a radical rethink of the type of cars driven there. One solution could be a car like Nuvu, designed for the city of the not-too-distant future.

“Nuvu is literally a ‘new view’ at the future of the city car. It is electric, of course, but as far as Nissan is concerned, for tomorrow’s city cars that is a given. No, the most important aspect of Nuvu is the interior design which provides great comfort and space in an intelligent package designed to make best use of our crowded roads and limited parking slots.”

François Bancon, General Manager, Exploratory and Advance Planning Department, Product Strategy and Product Planning Division, Nissan Motor Co., Ltd.

Overview
There is about to be a seismic shift in the urban landscape. Within the next five to seven years, some 55 percent of the world’s population will live in the city, threatening total gridlock. Unless something is done, the irony of the phrase ‘personal mobility’ will be self-evident.

Look around at the cars in a typical city traffic jam today and the vast majority will have only one occupant and four empty seats. Some might have two occupants, a few three. But find one with four occupants or more and you’ll be doing very well.

Today, we buy a family car knowing that we’ll only ever need to use it to its full potential one or perhaps two percent of the time. Tomorrow, things will be different. Tomorrow, things have to be different.

“There is a new generation coming up who, finally, are questioning why we do the things we do. They are asking themselves, for example, why they are buying a large car when they know that for 99 percent of the time they will be in it on their own,” says François Bancon, General Manager, Exploratory and Advance Planning Department, Product Strategy and Product Planning Division, Nissan Motor Co., Ltd.

“It is our job to provide personal transportation that is better suited to people’s needs and to what the environment – in all senses – can cope with.”

Nissan’s vision for the future of urban transportation is encapsulated in Nuvu, a ‘new view’ of the type of car we will be driving in the middle of the next decade. Compact – it’s just 3 metres long – Nuvu is a concept vehicle with unique 2+1 seating. It is aimed at urban dwellers who don’t want to compromise on their personal freedom or their comfort, yet who appreciate that ‘something has to give.’

Nuvu is agile, easy to drive, even easier to park. And it is, of course, an electric vehicle (EV). As Bancon says: “We believe zero emission vehicles are one of the key solutions for tomorrow’s city car.”

Nuvu is described as a moving oasis, a haven of green tranquillity in the urban jungle. To underline this message, Nuvu incorporates a witty representation of its green credentials: across its all-glass roof are a dozen or so small solar panels. Shaped like leaves on a branch, the power they generate is fed to the battery using a ‘tree trunk’ within the car as a conduit. Nuvu also uses natural, organic and recycled materials within the cabin.

Nissan has already announced plans to introduce an all-electric car in Japan and the US in 2010 and to mass-market it globally in 2012. Nuvu is not that car, though it does share some of the technology that will feature in the planned production vehicle. Rather, it is a concept of how a Nissan EV might look in the near future.

In the longer term, Nissan foresees a future based around a line-up of zero emission vehicles regardless of their size, category and usage. Nuvu – or its production equivalent – is just one element of this emission-free future.

Nuvu in detail
The central thrust behind the development of Nuvu is not its motive power but its layout and use of space. Nuvu has been created for a city of the future, one that’s even more crowded than today.

That’s why it’s compact on the outside yet roomy on the inside. Built on a unique platform, it’s just 3 metres long and sits on a wheelbase of 1980 mm but is 1700 mm wide and 1550 mm tall to create a large and airy cabin.

Interior package
These dimensions provide all the interior room needed for the vast majority of city journeys. Nuvu has two regular seats and a third occasional chair that can be folded down when required. But, unlike some two-seater city cars currently on the market, it is a thoroughly practical proposition with an integral luggage area providing sufficient space for a typical supermarket or shopping expedition.

“It is a real car,” says Bancon. “There would be no disadvantages to using a Nuvu everyday. For the vast majority of users, three seats are more than enough most of the time.”

The packaging is designed to give priority to driver comfort with C-segment levels of space and the flexibility to invite one or two passengers on board. Cabin layout places the regular passenger seat beside but largely behind the driver’s seat, allowing the passenger to stretch right out. Ahead of this seat is a third occasional chair which, when not in use, is folded away into the dashboard assembly. But even when the third seat is in use, there remains sufficient legroom for both passengers.

In the interests of saving both weight and space, the third seat has a centre section made from hardwearing yet comfortable netting. This hammock-like approach also has the benefit of allowing cool or warm air to circulate around the occupant’s body for extra comfort.

Shopping bags, briefcases and smaller items of luggage can be stowed behind the driver’s seat while if the driver is travelling solo, larger items can be stowed in the passenger footwall.

City car research
“We did a great deal of research into how people use their cars in the city. We found that for 90 percent of the time, the driver was alone. For five percent of the time there was one passenger and for four percent of the time there were two passengers. You can do the math to find out how often four or more people were in the car!” says Bancon.

“We gave the second seat much more room than normal because when you take one passenger in your car it is usually someone you love and you want to make sure he or she is being carried in outstanding comfort,” he adds.

Natural materials
Many of the materials used inside Nuvu reflect an increasing concern for the environment. The floor is made from wood fibres pressed into laminate sheets and is studded with rubber inserts made from recycled tyres for grip.

To create a light and bright interior, the windscreen and roof merge into one extended panel running virtually the entire length of the car. But undoubtedly the most unusual feature of the interior is the ‘energy tree’ which rises from the luggage compartment floor to the roof behind the driver’s seat.

Solar panels
The energy tree is shaped like a thin trunk. As it reaches daylight it branches out under the glass roof providing occupants with protection from bright sunlight… just like a real tree. And providing a visual reminder of Nuvu’s green credentials, covering the branches are dozens of small solar panels shaped like leaves.

The panels absorb energy from the sun which is then fed back down the energy tree and used to help recharge the battery and provide an extra power boost for the electric motor. As well as being genuinely green energy, it is estimated that the power generated via the solar panels will save the equivalent of one full overnight charge from mains electricity each month.

Driver controls are as simple as possible. All the major functions – steering, braking, transmission and throttle – are ‘By-Wire’ while the steering is controlled by an aircraft-style steering yoke: with just one turn from lock to lock, the steering is very direct for agility and manoeuvrability in the city. Nuvu’s turning circle is just 3.7 metres. Thanks to its wide track and the use of 16 inch 165/55 tyres mounted on lightweight, almost transparent, wheels, ride comfort, stability and agility is of the highest order.

There are two pedals – for stop and go – stalks for minor controls and a digital instrument panel with dials for speed, distance covered and battery range. The instrument panel itself is formed of layers – rather like an onion – and like the energy tree is another example of design inspired by nature. “We call it bio-mimicry,” says Bancon.

Rear view/parking monitor
Two screens on the dashboard display the view behind the car – there are no door mirrors to disturb the airflow, but small cameras – and double as monitors for the Around View Camera which give a bird’s eye view of the car when manoeuvering or parking.

Saving energy was the guiding force behind the use of low-energy LED head and tail lamps, while Nuvu’s heating and ventilation system filters and cleans the city air as it passes through the vehicle. Not only does it produce no emissions at source, but Nuvu actually helps clean up the city environment.

Exterior and interior design
“Nuvu’s design is further clear evidence of Nissan’s continued desire to challenge convention and to explore all the possibilities that the EV could bring us. In many ways it was inspired by our two most extreme EVs of recent times: Mixim and Pivo 2.

“Significantly, though, Nuvu delivers a more realistic interpretation of two of the most important aspects of its forerunners – the ‘Friendly Innovation’ found in Pivo 2 and the ‘Sports Dynamics’ central to Mixim

“The result? We have designed a radical concept car that with just a few changes could go into production tomorrow,” explains Masato Inoue, Chief Designer, Product Design Department, Nissan Motor Co., Ltd.

Developed by designers at Creative Box Inc. – Nissan’s design think-tank – Nuvu’s green house has flowing lines with gentle curves inspired by nature. The distinctive shape of the door glass on either side gives the impression of a hot air balloon that’s being gently inflated by pressure from within, while tropical fish inspired the profile of the side window graphics as a whole.

This contrast between the natural, fluid shape of the greenhouse and the strength implied by the solidity of the lower body gives Nuvu a feeling of quality rarely found in a compact car.

Colour and materials
Nuvu’s visual impact is further enhanced by its unique body colour. Developed by Nissan Design, the shade is officially called Soft Feel Sandy Gold.

Matching the ecological values of an electric vehicle, the moulded plastics and synthetic elements found inside a typical production car have been replaced by natural materials and organic alternatives, such as the wood fibres and rubber from car tyres used for the flooring. The result helps create a relaxed, warm atmosphere within Nuvu’s cabin.

During the design development stage, key targets were to develop an EV that encompassed obvious modernity with engaging ambience and a playful aspect – hence the energy tree. “You don’t need to be a car lover to fall in love with Nuvu,” adds Bancon.

EV drivetrain
Nuvu is more than a styling concept of a future EV. It is a fully working mobile test bed for much of the technology that will be used in Nissan’s production EV to be launched in 2010. For this reason elements of its technical specification are being kept secret for the time being.

The electric motor used in Nuvu is mounted at the rear of the vehicle and drives the back wheels, though neither its exact specification nor the power and torque figures are being released at this stage. A driving range of 125 kms and top speed of 120 km/h are being made public, however.

Li-Ion battery
Similarly although it can be revealed that the batteries used are of the latest laminated lithium-ion type and have a capacity of 140 Wh/kg (watt-hours per kilogram), the total capacity of the batteries and number of modules are not being disclosed at this stage.

Nissan began research into high output Li-Ion cells as long ago as 1992, but today development is carried out by Automotive Energy Supply Corp. (AESC), a joint venture company set up by Nissan and NEC Group.

Unlike a conventional lithium-ion battery with its bulky cylindrical cells, the laminated Li-Ion battery as used in Nuvu has thin laminated cells and fewer components overall. This boosts its power by a factor of 1.5 at the same time as halving its physical size. It also remains twice as efficient as a conventional cylindrical Li-Ion battery even after five years or 100,000 kms of continuous usage.

Another bonus of the compact cell construction is that a thin modular design is possible with a commensurate improvement in battery cooling efficiency. Higher power outputs are achieved through material improvements made to its lithium manganate positive electrode and carbon negative electrode. The use of chemically stable spinal-structured manganese for the positive electrode also helps ensure safe operation.

Its compact size allows the batteries to be mounted under the seats and the vehicle’s flat floor, thus helping to keep the centre of gravity as low as possible.

A quick charge from empty to full should take between 10 to 20 minutes while a full charge should take between three to four hours from a domestic 220V socket.

Typical users
“The people who will be drawn to a car like Nuvu are many and varied,” says Bancon. “It is a cross generational car and not a signature vehicle for one generation.

“There will be common threads, however. They will be early adopters but more importantly they regard themselves as urban citizens. They don’t just work or live in the city; they are part of the city. They want a car that somehow expresses who they are and which reflects their personal ideology.”

Conclusion
Although clearly a concept vehicle exploring aspects of future vehicle design, Nuvu nevertheless embodies many messages for today. Its clever interior provides ample headroom, legroom and comfort for most everyday needs without occupying more road space than it needs.

The use of recycled and natural materials underlines Nuvu’s environmental message and while the energy tree might be considered as a piece of whimsy, the use of solar energy is an entirely sensible and practical technological solution to aid an emission free future.

“Nuvu is a concept car, for sure, but it is an entirely credible vehicle,” says Bancon. “It is light, clean and easy to drive. It is practical and a sensible size, yet it is also embodies an element of fun: the future doesn’t look so bad, after all.”

ONDELIOS: AN ENVIRONMENTALLY-FRIENDLY LONG-HAUL JOURNEY

The Paris Motor Show sees the wraps come off Renault’s top-of-the-range concept car Ondelios designed for lovers of long-haul travel who set store by comfort and refinement. Ondelios epitomizes Renault’s vision of the high-end crossover, combining a comfortable ride with respect for the environment. Clear illustrations of that vision are the vehicle’s ethereal design, its interior layout, and an original hybrid powertrain.

A sleek design that answers the call of the open road
The 4.8-metre-long, 1.6-metre high Ondelios has drawn inspiration from the world of aviation design to deliver high drag efficiency and a Cd of just 0.29. This long-distance voyager boasts sleek, smooth, amazingly fluid lines that make it appear as though it glides over the ground. It embodies Renault’s vision of high-end car. “Ondelios is inspired by motion rather than speed and is a whole new response to the call of the open road,” enthuses Patrick Le Quément, Renault’s Design Director.

The aluminium-finish grille is flanked by headlamp units that also suggest flowing motion, while its high-performance LED headlights are both longer lasting and more efficient. Another feature of Ondelios’ aerodynamic styling is the boomerang-shaped tail lights. They are built into the bodywork and ringed with air extractors to control the flow of air from the wheel arches. The glazed roof further emphasises the vehicle’s airy look and feel, bathing the interior in natural light. The steeply raked windscreen, which extends well down the bonnet, further accentuates this ethereal feel.

“We think of it as made from a single material, where the body and glazed areas merge into one. Ondelios is a glimpse of what the automobile might be in the medium term future,” adds Patrick Le Quément. The butterfly-type side doors, which also feature an extensive glazed area, add a further touch of elegance to the car’s overall styling. They swing out and upwards as the sills slide down to facilitate ingress.

The dark blue anthracite of the bodywork blends perfectly with the tinted glazed area, making the car look as if it were all of a piece and a single colour. The tailgate’s upper section rounds off the sleek, aerodynamic lines with a profiled glareshield that slides inwards to air and cool the cabin.

Ondelios sits on seven-spoke, 23-inch aluminium alloy wheels which contribute to its profiled styling. The propeller-like hubs draw airflow from the sides of the car to prevent turbulence. They operate in conjunction with the rim-side brake discs to ensure they suck in air effectively.

The sleek sidewalls of the large diameter 255/40 Michelin Pilot Sport tyres deliver outstanding drag performance. Their tread pattern is designed to minimise deformation of the contact patch while on the move to help curb rolling resistance. The tread has efficient, active flow channels which, together with the wide circumferential
groove that helps clear water, strengthen the image of a high-end, high-tech tyre.

Business-class comfort for a long-haul journey
The elegance of the Ondelios interior is in harmony with the call of the open road suggested by its exterior. To begin with, its layout is designed to profit from all the available space. There are three rows of seats that offer individual seating for six. With their cantilever mounts they give the impression of floating, while their kinematics are redolent of airplane seats. The electrically adjustable backs fold into comfortable, business-class positions, while occupants can deploy and retract their footrests at will. Although their slim lines speak of lightness, they are
designed, like giant leaves, to hug their occupants who can curl up in them to enjoy the comfort and support they afford. The height of the seats is carefully designed to ensure occupants are perfectly at ease when they talk to each other.

Unlike conventional door opening systems, the doors are hinged to the roof, which makes getting into the car extremely easy. The second row of seats slide forward and folds down to facilitate access to the third row.

In addition to seating comfort, the cabin exudes a highly refined ambience. The materials used are drawn from contemporary interior design and give the impression of sitting in a lounge on wheels. They blend soft, supple textures like light grey leather and fabric, as seen on the dashboard, seats and door panels. The colour of the seatbacks blends gradually from ochre to purple, further enhancing the sense of security and comfort.

Interior features and fittings are both modern and intuitive. The ergonomically designed controls, in keeping with Renault’s touch design approach, afford users efficient, comfortable ease of use.

The ample, flowing yet sober design of the broad dashboard echoes the car’s aerodynamic exterior. It is further highlighted by a roomy, suspended stowage compartment which is protected by a lit shell, while all the dashboard’s functional components are particularly user-friendly:
- active display skins show driver aid and ride information;
- a monitor at the base of the windscreen displays the different menus and pictures from the
door mirror cameras;
- three large strip displays provide driving-related information, revs and how the hybridized
drivetrain is operating;
- a digital speedometer.

The technologies with which Ondelios is equipped enhance the collective and individual well-being of all occupants. All the passengers, including those in the back row, have their own Samsung interactive portable multimedia devices which they can use for sharing data or multiplayer gaming. Speakers are also incorporated into the headrests and a multizone HVAC system enables each passenger to set the temperature to his or her own liking.

The smart technologies that have gone into designing Ondelios help drivers to settle in at the wheel, include a Samsung cell phone which also acts as a hands-free door lock recognizes the driver and loads all his or her personal settings, e.g. seat-adjustment settings and favourite music. The vehicle adds a final, friendly touch in the form of the back-lit logo which lights up to show that it has recognized the driver.

An environmentally friendly voyager
To complement the extensive work that has gone into Ondelios’s aerodynamics, some of the car’s structural parts are made from natural flax fibre for greater recyclability. In keeping with the commitment to make the car as light as possible, its body is made from carbon and the glazed areas from polycarbonate.

Ondelios is powered by a hybrid powerplant which combines a more powerful 205hp (150kW) version of the 2.0 dCi engine, with two 20kW electric motors at the front and rear. They operate in mild hybrid mode, giving the engine extra boost as required. They use a brake and boost system, recovering energy during braking then delivering it to the engine to boost acceleration. The front motor also uses fuel-saving stop-start technology.

The electric motor mounted on the rear axle drives the rear wheels when the ESP sensors detect a loss of traction, thus giving Ondelios the capability of a 4WD vehicle. The car is equipped with a lithium-ion battery that can deliver power of up to 4kW/h. With torque of 450Nm between 1,700 and 3800rpm, the diesel engine provides comfort and flexibility at all engine speeds for long-distance driving pleasure. The 2.0 dCi unit takes Ondelios from a standing start to 100kph in just 7.8 seconds. Driving through a seven-speed, double-clutch gearbox, it affords outstanding driving pleasure, while keeping fuel consumption at a frugal 4.5 litres/100km and CO2 emissions at a lowly 120g/km – very impressive for a top-of-the-range vehicle. Similarly, the body, chassis design and hybrid powertrain contribute decisively to protecting the environment.

Ondelios is a long-distance travel-loving aerodynamic crossover born for the open road. It is proof that caring for occupants and the environment is entirely compatible. Ondelios is a concept car that illustrates Renault’s vision of the high-end car of the near future.
