Rinspeed iChange Concept

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.
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 that are available in two different stack configurations for short- and long-distance driving. 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 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.

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.

With the Rinspeed iChange Concept Rinderknecht, a passionate C. F. Bucherer watch wearer, and his partners once more want to provide food for thought for the automotive industry. The Swiss car visionary: "If we want to maintain our individual mobility in the future we have to rethink the car in its entirety, without taboos. Most of all, we have to take its ecological aspects into consideration." And in the end everyone has to personally answer the same question: Am I ready and willing to change myself, do and can 'I change'?

Rinspeed sQuba Concept, 2008

The Thirty 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 movie fake now becomes reality for visitors of the Geneva Motor Show (March 6th - 16th, 2008). Rinspeed boss Frank M. Rinderknecht (52) is known for his extraordinary automotive creations. The acknowledged James Bond enthusiast and Swiss automobile visionary kept revisiting this scene in his mind over and over: "For three decades I have tried to imagine how it might be possible to build a car that can fly under water. Now we have made this dream come true."

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 materials, so-called Carbon 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's 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.
