Rinspeed iChange Concept, 2009

The Swiss auto powerhouse Rinspeed presents the Rinspeed iChange Concept, the world's first car whose body adapts to the number of passengers on board. For Rinspeed boss Rinderknecht the vehicle is more than just a clever concept car. "The Rinspeed iChange Concept is a symbol for the fundamental changes the auto industry undergoes worldwide. And it is clear that only those companies will survive that have innovative answers for the demands of a new automotive era." The visionary Rinderknecht is convinced that the days of gas-guzzling behemoths are coming to an end: "The Rinspeed iChange Concept is a signal for the coming global changes to individual mobility. We need to be ready to meet these challenges with new ideas."

In seconds a streamlined one-seater sports car transforms into a comfortable car with ample room for three. The trick: At the push of a button the rear end of the teardrop-shaped car magically pops up. "We have designed and built an extremely flexible vehicle. In it we have brought the themes of versatility and continually changing energy demands to their logical conclusions." The result is a streamlined, lightweight zero-emission car with dramatically reduced energy consumption.

The basic idea behind the 'Rinspeed iChange Concept: The energy demand of a vehicle depends mostly on its weight, the type of engine it uses, and its aerodynamic properties. The engineering-services company Esoro that traditionally builds Rinspeed concept cars has built an extremely lightweight car weighing in at only 1050 kilograms. To power the car, the Swiss specialists chose an electric motor. The idea of the pop-up rear end was conceived to account for the sizeable effect aerodynamics play in fuel consumption.

The energy for the electric motor comes from lithium-ion batteries. The electric motor of the Rinspeed iChange Concept produces 150kW, capable of propelling the car to a top speed of 220 km/h. The sprint from rest to 100 km/h takes just slightly over four seconds. This impressive performance is made possible with the help of a six-speed pre-selector gearbox from the Subaru WRX car. The central research department of Siemens AG (Corporate Technology, CT) supplied the integration technology for engine/generator, electronics and battery connection interface. Siemens has long been one of the world leaders for energy systems and eco technology with pioneering concepts for electric drive systems. Its products cover the entire electric value-added chain from generation to distribution to consumption. The gearbox and drivetrain are lubricated with eco-friendly lubricants from Motorex. Custom-made lightweight 17" and 18" forged wheels with aerodynamic shrouds are supplied by light-alloy wheel specialists AEZ. Pirelli P Zero tires in size 215/40-17 in front and size 245/40-18 in back provide optimal grip.

An initial walk-around reveals that the concept car has no doors. The entire electrically powered roof section of the car measuring just 1.03 meters in height tilts forward to allow passengers to board. Also gone are such mundane things as a key. The Rinspeed iChange Concept is drastically different than ordinary cars in every detail: At the heart of the concept car lies the groundbreaking next-generation Harman/Kardon infotainment system. The system uses an innovative Intel processor technology that guarantees minimized power consumption. The same is true for the Harman/Kardon high-efficiency audio system. This revolutionary technology meets highest demands on sound quality, weighs much less than ordinary systems and at the same time uses only a fraction of energy. The opens the door to a new dimension of energy efficiency. The route guidance of the navigation system is also especially eco-friendly: The system calculates the most energy-saving route and displays the directions in realistic 3D view. Eberspächer Group from Esslingen, Germany is one of the world leaders in car heaters. Specifically for the „iChange" project Eberspächer developed custom-tailored electric and fuel-burning heating systems. Both systems are geared toward the specific requirements and conditions of electric vehicles.

The pure wool used in the interior was further refined into high-tech wool by Schoeller using state-of-the-art processes. The wool is spun and died in accordance with the highest eco standards. It provides an extremely extravagant ambiance in the Rinspeed iChange Concept, looks stunning and is delicate to the touch. The competence partner Strähle + Hess transformed this natural product into a striking interior. Its surface character and materiality combine to create a symbiosis of shell, firmness and frothy air. Unconventional techniques create unusual surfaces. The seams of the seats are reversed and the removable seats cushions are adorned with the prototype's name. Xmobil provided further customization services. While textiles can be found in the Rinspeed iChange Concept in their original form in other areas, they are newly interpreted on seats and cargo floor using various refinement techniques such as braiding and gathering and a combination of both. Leather strips alternate with technical textiles. The seat cushions are interchangeable, braided felt alternates with technical textiles formed into three-dimensional shapes. This transfers the adaptive concept of the Rinspeed iChange Concept to the interior as well. The diamond-coated anti-slip floor is supplied by abrasives specialist KGS.

The Swiss Federal Ministry for Energy (Bundesamt für Energie) supports the „iChange" project as a groundbreaking research and development project. Solar panels on the top and sides of the roof provide electricity to the fan to keep temperatures in the Rinspeed iChange Concept comfortably low on hot summer days. The large Sharp solar panels also provide additional eco-friendly charging of the batteries.

Rinspeed sQuba Concept, 2008

The 30 years after the movie thriller 'The Spy Who Loved Me' hit the silver screen Rinspeed sQuba is the first car that can actually 'fly' under water.

Zumikon - "Dive it again, James!" If the situation gets too hot for the secret agent he'll go underground - or under water. So demonstrated impressively by Roger Moore in 'The Spy Who Loved Me" in 1977 when he dove below the waves in a sleek vehicle that moments before seemed to be an ordinary car. The only problem: The scene never really took place; it was an animation.

With the Rinspeed sQuba, the world's first real submersible car. The acknowledged James Bond enthusiast and Swiss automobile visionary kept revisiting this scene in his mind over and over.

This submerged stabile flight at a depth of 10 meters that sets the Rinspeed sQuba apart from military vehicles. While the latter can go under water, they are limited to driving slowly over the submerged ground. Rinderknecht: "It is undoubtedly not an easy task to make a car watertight and pressure resistant enough to be maneuverable under water. The real challenge however was to create a submersible car that moves like a fish in water."

It also had to be a sports car that was converted into a diving dream in the facilities of Swiss engineering specialist Esoro. In a first step the combustion engine was removed and replaced by several electric motors. Three motors are located in the rear. One provides propulsion on land, the other two drive the screws for underwater motoring. They are supported by two powerful Seabob jet drives in the front, which 'breathe' through special rotating louvers from HS Genion (for opening and closing the water intake). The rotating outlet jets were designed to be extremely light yet twist resistant by using high-tech nano materials, so-called Carbon Nano Tubes.

It is a sure bet that the Rinspeed sQuba will steal the show from any 'Baywatch' beauty on the beach. And easily, too: You drive the car into the water and the car floats. That is, until you crack the door to let the water in. Immediately the Rinspeed sQuba starts on his way to the underwater world. The occupants' breathing air comes from an integrated tank of compressed air that divers know from scuba diving. Rinderknecht: "For safety reasons we have built the vehicle as an open car so that the occupants can get out quickly in an emergency. With an enclosed cabin opening the door might be impossible." But safety wasn't the only reason for choosing an open-top design: With an enclosed volume of just two cubic meters of air the vehicle weight would have to increase by two tons (!) to counteract the unwanted buoyancy, giving the Rinspeed sQuba the land mobility of a turtle. Without occupants the Rinspeed sQuba surfaces automatically.

It is even capable of autonomous driving on land thanks to a sophisticated laser sensor system from the Hamburg company Ibeo - without any help from the driver or passenger.

Power is supplied by rechargeable Lithium-Ion batteries. Rinderknecht: "The 'sQuba' is a zero-emission car as documented by the rotating license plate in the rear. It produces no exhaust emissions. The Swiss are among the world's pioneers in the area of hydropower. The 'sQuba's' filling station is the water reservoir." It is no surprise that the vehicle features powerful yet energy-saving LED lighting technology.

3-D foil elements with embossed fish and sharkskin patterns from Wetzel Processing Group and Hornschuch add visual pizzazz and streamline the exterior. Together with styling elements from Foliatec they create a harmonious velvety matt-white appearance.

For shore leave the Rinspeed sQuba relies on a stainless coil-over suspension from KW automotive and large Pirelli tires mounted on custom-made forged light-weight wheels from AEZ with 17- and 18-inch diameters. But the Rinspeed sQuba is really at home in the water. To make the occupants feel at home there as well the innovative salt-water resistant interior from Strähle + Hess features genuine mother-of-pearl trim and diamond-plated non-slip inlays from KGS Diamond, normally used in high-tech abrasives. After all, 'diamonds are a girl's best friends.' The high-tech VDO instrument cluster and controls create a futuristic ambiance and allow controlling all vehicle functions even while submerged.
