Renault Symbioz: Experience Tomorrow Today – Autonomous, Electric And Connected
• We are on the cusp of making history. Imagine you set out on a journey to work or for leisure, strapped inside a bullet – that accelerates as fast as a sports car – quietly, allowing you to take your mind off the road ahead, while you’re surrounded by concert-quality sound and cinema-quality screens. You arrive relaxed. Caught up. Entertained. Is this the future? Renault thinks so. But we’re providing a taste of it today with the SYMBIOZ demo car.
• After unveiling a vision for 2030 with SYMBIOZ, the concept car and house, at the Frankfurt Motor Show in September 2017, the SYMBIOZ demo car is the first rolling prototype built to be autonomous from the ground up, that gives us a more near-term experience to 2023.
• The SYMBIOZ demo car road tests provide Renault with the opportunity to demonstrate in real-life conditions a car that is autonomous, electric and connected, resulting in a whole new on-board experience and as much pleasure while driving as with hands off the steering wheel. In SYMBIOZ, the driver can automate driving and use travel time for other activities. We believe car travel will become a multi-sensory, personalized experience, with a cabin reconfigured differently for each driving mode, and the car becomes part of driver’s and passenger’s own ecosystem.
Renault SYMBIOZ demo car: The Car
“Technological advances in autonomous driving open up new opportunities for ways of using cars, especially new travelling experiences. The SYMBIOZ demo car is the first vehicle that has been designed for mind-off automation from the start. On authorised highways, the driver can fully delegate driving and concentrate on other things. This exploratory exercise has helped us to envisage what the future will look like for car occupants. As such, it’s been a really important and inspiring learning experience for our engineering and design teams.” Mathieu Lips – Director, SYMBIOZ demo car project
Advanced, Level 4 autonomous driving for additional free time
Autonomous cars use technology that is new to the industry. One of the goals of the SYMBIOZ demo car is to enable Renault to make the transition from theory to practice, to allow its engineers and designers to address the many challenges and opportunities presented by autonomous driving.
- From base level driving assistance like cruise control to full driving automation in any roads, SAE International* has defined five levels of autonomous driving. The SYMBIOZ demo car is capable of reaching Level 4, also known as ‘mind-off’.
- Level 4 frees up the driver from all dynamic driving tasks when the car’s automated driving system is switched on. It is no longer necessary for the driver to concentrate on the road ahead. The car is capable of moving into a safe position if it cannot deal with an unexpected incident ahead.
- On authorized highways or dual roads with a median strip, a Level 4 autonomous car like SYMBIOZ demo car can adjust the vehicle’s speed in accordance with the car in front, stay in its lane even when cornering, change lanes (i.e. to overtake another car or exit the highway) and function alone in traffic jams.
Level 4 driving automation is currently not permitted under French road rules. However, France’s road authorities (and similar organisations in other countries) allow trials to take place if someone is travelling in the car and can supervise the autonomous drive mode. This person needs to be able to take back control of the vehicle at any time. The SYMBIOZ demo car road tests will be conducted under these provisions.

- The batteries can then be charged to 80 percent of their capacity in less than half 1 hour.
Zero CO2 emissions and zero emissions of regulated pollutants during road use, in compliance with NEDC, excluding wear parts.
Innovative, people-focused design
- The innovative exterior design perfectly matches Renault ‘French Design’ styling: it is sensual and warm with fluid lines and a dynamic stance.
- The design is accentuated by the ‘Champagne’ body colour and pearlescent finish.
- As a low-slung, one-box car with sporty looks, SYMBIOZ demo car is:
- 4.92 metres long
- 1.92 metres wide
- 1.44 metres high
- mounted on a wheelbase of 3.07 metres
- The car’s steeply raked windscreen accommodates new interior features such as a horizontal layout and storage areas on the dashboard.
- The car’s upper section boasts a vast glazed surface to let ample light into the cabin and optimise outside visibility without detracting from the impression of robust strength.
- The floating glass roof takes on an iridescent appearance.
- It features a system to adjust the opacity of the glass and the LED lighting that can be accessed from the Renault MULTI-SENSE 3.0 system interface.
- To improve the car’s efficiency, the SYMBIOZ demo car is fitted with a range of all-new aerodynamic features:
- Vertical air intakes in front of the front wheels and extractor vents behind them to reduce drag and turbulence
- Side wind deflectors to channel the air flow as close as possible to the car body
- Roof spoiler which deploys automatically when the car reaches 43mph (70kph)
- The side wind deflectors house sensors that can unlock and open the rear doors and a third stop light is built into the wind deflector located on the roof.
- The SYMBIOZ demo car’s exterior styling incorporates various sensors for autonomous driving:
- Lidars concealed in the front head lights and rear bumper
- Radars and ultrasound sensors positioned behind the bodywork
- Front camera in the upper part of the windshield; rear camera built into the Renault diamond logo
- Lateral cameras hidden in the door handles
- The model’s exterior lighting signature includes C-shaped lights both front and rear. This is a Renault design hallmark today that will extend to the future.
- To assert its personality, the SYMBIOZ demo car lights up in blue when autonomous drive mode is activated, also making it easy for surrounding cars to know it is operating in this mode.
The exterior lines of the SYMBIOZ demo car were also designed to showcase the interior with its many design features devoted to travelling comfort.
- The cabin layout has been flexibly designed to accommodate the car’s different driving modes and Level 4 ‘mind-off’ automation, allowing the driver to stop paying attention to the road and do something else. For example:
- There is no centre console
- The air vent system has been redesigned to achieve a flat floor through to under the dashboard
- The storage areas in the dashboard have been moved to free up space on the sides
- The door panels have been optimised with built-in lighting
- The SYMBIOZ demo car boasts a living room-style cabin with a focus on safety and comfort in the individual seats for each passenger.
- The front seats offer a degree of modularity never previously seen in a car: the ‘zero gravity’ position in the RELAX layout and the front armrests automatically drop down and the seats turn 10 degrees towards the inside in the LOUNGE layout.
- The rear of the cabin has been designed like an alcove, with a concealed rear window, for greater privacy.
- The cockpit layout of the SYMBIOZ demo car changes automatically according to the driving mode selected.
- In the AD mode, the steering wheel and dashboard move back 12 centimetres to free up space in front of the driver.
- In the Dynamic mode, the driver’s seat features additional lateral support for a bucket seat feel.
- The L-shaped digital display developed by LG saves cabin space, while also providing new features.
- It comprises three customizable OLED screens which display information in real time about driving, navigation and cabin comfort.
- This display offers a unique user experience especially for on-board entertainment: you can watch a high-definition movie or discover the activities proposed on the next rest area of the highway.
- The car also features a large windscreen-mounted head-up display to provide the driver with data from the autonomous drive system
Renault SYMBIOZ demo car: The Experience
Three driving modes and three journey experiences
Courtesy of the Renault MULTI-SENSE 3.0 system, an upgraded version of the current MULTI-SENSE system, the SYMBIOZ demo car features three driving modes:
- The Classic mode is the standard mode. Occupants are at one with the car and feel at home. The driving position is conventional and the car’s settings are focused on comfort.
- The Dynamic mode boosts driving sensations. Driving is more active and the driver’s seat features additional lateral support for a bucket seat feel. The engine response, steering and chassis settings are all geared towards a dynamic driving style.
- The AD mode optimises the space available in front of the driver so they can do different things. When the AD mode is switched on, the steering wheel and dashboard – which comes with a unique L-shaped display – automatically move back 12 centimetres.
The driving mode is selected by pushing the Renault logo in the middle of the steering wheel which is lit up like a hologram.
In AD mode, the driver can choose from three layouts depending on how they want to spend their free time.
- The Alone@Home layout frees up space by retracting the steering wheel and dashboard and taking advantage of the extra foot room provided by the vehicle platform which has been optimised for autonomous driving and to house the electric motor (no centre console or transmission tunnel).
- The Relax layout enables the driver to sit back and relax in their seat in ‘zero gravity’ position. They can use a special headset developed by Ubisoft to enjoy a virtual reality experience simulating different environments and settings.
- The Lounge layout lets the driver move closer to the person in the front passenger seat. The front armrests lower automatically and the seats turn 10 degrees towards each other to facilitate conversations between the driver and front-seat passenger.
A glimpse into the future of entertained travel
The SYMBIOZ demo car is packed with technology. Of course, what is most important are people and what sort of experience they can enjoy. In this respect, the car is very much part of the people-centric ‘Easy Life’ approach core to Renault’s DNA. SYMBIOZ demo car truly allows the driver and passengers to ‘engage the senses’ during journeys.
The journey starts at home. In our scenario, the passenger’s personal agenda is displayed on the home TV, updated via smartphone, tablet or PC and shared between the car and the home.
- Fifteen minutes prior to departure, trip information is displayed on the home TV and the tablet inside the house. This will include the destination, hotel booking and an option to update Facebook, among other information.
- Five minutes prior to departure, information about the car (charge level, driving range of batteries) and the journey (traffic and weather) can be displayed instead.
- The driver can call the SYMBIOZ demo car on their smartwatch (connected to their smartphone). The car then picks up the driver and passengers – this is the ‘valet parking’ feature associated with the car’s autonomous drive mode. The driver can watch the car approach from outside, courtesy of a bird’s-eye view camera.
Onboard SYMBIOZ demo car, the Renault MULTI-SENSE 3.0 system, an advanced version of the current MULTI-SENSE system, reinforce the sensory experience delivered according to the driving mode selected. Three sensory experiences will be available with different lighting environments, acoustic ambiences and in-car fragrances.
- Lights on! SYMBIOZ demo car surrounds its passengers with selected colors to enhance the feeling of well-being on board. The lighting environment varies according to the situation and driving mode.
- When getting into the car, the driver is welcomed by a wave of light running along a belt of LEDs positioned mid-height on the doors and dashboard.
- Dynamic light displays are featured in each driving mode
- In the Dynamic mode, for example, a red light runs from the back to the front of the vehicle.
- In contrast, selecting the AD mode bathes the cabin in a gentle gold ambient light.
- A “wow effect” is also guaranteed with the sound environment. Courtesy of a partnership with Devialet, SYMBIOZ demo car unleashes the full emotional impact of sound, helping to redefine automotive travel experience.
- Audio modules feature the same technology as Devialet’s Phantom speakers but on a much smaller scale.
- They are built into the car’s centre pillars, the middle of the dashboard and between the rear seats.
- The modules are connected to sound bars that run around the cabin.
- The resonance of the interior materials was taken into account in order to optimise sound resonance in the cabin.
To illustrate an extreme of “mind off” driving, the virtual reality experience designed by our partner Ubisoft is another way to enjoy the whole new experience proposed while travelling in autonomous mode with SYMBIOZ demo car. Immersive and contemplative, the experience allows the driver to sit back and relax while the vehicle is in autonomous drive mode.
- Put the helmet and change your vision! A virtual reality headset can be worn to enable the driver or its passengers to go on a virtual journey. It begins with a realistic real-time representation of the car and road before taking them to more abstract and surreal places.
- To interact with the real-life environment, the system uses data from the car, such as speed, trajectory and position on the road and other cars detected nearby by AD sensors.
- This provides a link between what the driver can see when they look through the virtual reality headset and what their body actually feels so they do not suffer from motion sickness.
- It also heightens the immersive environment and the feeling of getting away from it all, while delivering a unique experience specific to each journey.
- Passengers will also enjoy a specially-scented environment. Three fragrances – one for each driving mode available: Classic, Dynamic and AD – have been developed for SYMBIOZ demo car.
- The identity fragrance (in Classic mode) is based on the essences of the materials found in the cockpit. The different selected scents (ginger, cedar, birch, vetiver, etc.) provide a sweet, welcoming and warm identity.
- The Dynamic and AD modes fragrances are derived from this identity fragrance.
- In the Dynamic mode, the fragrance is more stimulating and energetic, thanks to the highlighting of ginger, cardamom and bergamot.
- In the AD mode, the fragrance opens the space being more airy and fresh, thanks to caraway, sandalwood, musk and saffron powder.
Renault SYMBIOZ demo car: The Ecosystem
“We designed SYMBIOZ Demo car keeping in mind that people want increasingly personal experiences, and the car too can be a very personal experience. We’ve decided to extend the use of the smartphone to allow SYMBIOZ Demo car to automatically recognize its drivers and passengers, which will influence everything from seat position to mood lighting and entertainment. We think people who try SYMBIOZ Demo car will be inspired by how customized their experience can be, and what’s possible in personal mobility of the future.”
Sandrine Woll – SYMBIOZ demo car project manager
The dividing line that has long separated the car from the home and the workplace is becoming increasingly blurred. Connectivity and constant data sharing between the different parts of the device ecosystem promise to better maintain a continuous link between all aspects of the customer's life.
The on-board connectivity system on the SYMBIOZ demo car allows the driver and passengers to access their digital lives and enjoy a wide range of services. In harmony with the personal smartphone, the customer's link to their media and data is never cut.
- Occupants are identified by their smartphone regardless of where they are sitting. The smartphone interacts with the car’s human-machine interface (HMI) to determine their seat settings, air conditioning settings and music preferences, among other functions.
- Thanks to a full suite of connectivity features (GPS, 4G, Wi-Fi), occupants can access their digital environment, media and services just like at home or in the office.
- The L-shaped dashboard display, which is the car’s primary HMI, lets users interact remotely with the outside world, like road infrastructures or their home.
- They can check what happens in their house thanks to a 360-degree camera view on the screen of the dashboard.
- They can also adjust the heating settings or access other domestic appliances like a fridge.
In connection with infrastructures
More and more, local, regional and national governments are exploring investments in the internet of things, smart cities, and ways to enable better communication between people, vehicles and infrastructure. Renault works closely with governments, NGOs and private sector partners as part of these efforts around the world to help advance sustainable mobility for all.
With SYMBIOZ, the journey is made more leisurely thanks to SYMBIOZ demo car connection to road infrastructure from Sanef’s network. Sanef is a subsidiary of the Albertis group, the world’s leading highway operator that Renault worked with on this project. This vehicle-to-infrastructure (V2X) trial uses communication protocols defined under the EU’s SCOOP project. Some examples of public-private partnership opportunities:
- Driving will be safer and more relaxing because the car can be warned in advance of any hazards up ahead, including roadworks, accidents, poor weather and congestion. This means the car is able to ‘see’ further than its own sensors.
- This V2X connectivity notifies the SYMBIOZ demo car of which toll lanes operate as electronic toll collection (ETC) lanes so it can go through a toll gate on the A13 highway in autonomous drive mode.
- The connection with road infrastructure also brings new types of data to the occupants of the car. Near a tourist spot, information about this place is displayed on the L-Shape screen of the dashboard.
A home at one with the car
On its stand at the Frankfurt Motor Show, Renault presented the SYMBIOZ concept car alongside a connected home to allow visitors to experience the way cars may be interacting with their environment in the future. When parked inside the home, the SYMBIOZ concept car showed how cars could play an even more important role in our everyday lives.
This connected home will also be on display during the SYMBIOZ demo car road tests.
- The house is 21 metres long, 7 metres high and 8 metres wide.
- It was designed for Renault by Marchi Architectes, the 2008 winners of the Nouveaux Albums des Jeunes Architectes Paysagistes (NAJAP) Award from the French Ministry of Culture and Communication.
- One of the up-and-coming architecture firms in France, Marchi Architectes share the warm, people-focused approach which is central to Renault’s design DNA.
- 80 percent of the rectangular-shaped ground floor’s glazed surfaces use clear glass, taking inspiration from the world of home design, to let in as much light as possible.
- The house has no interior pillars or walls, so it is easier to move around inside and provide a special area for the SYMBIOZ demo car to pick up occupants.
- The car is still visible from the outside of the house when it is inside because practically all the walls are transparent.
- The first floor of the house is cylinder-like and features a warm copper colour.
- This ‘night-time area’ includes the bedroom and the corridor to the rooftop terrace.
- Unlike the ground floor, the walls on the first floor are opaque for greater privacy.
- Three light wells at the top of the cylinder let light flood in to the ground floor.
- Some of the furniture and homeware inside the house have been designed by promising French designers who share Renault’s drive for innovation and authenticity. These include Ionna Vautrin (lights, worktops), Constance Guisset (mirrors, poufs), Iratzoki Lizaso (table, chairs), Guillaume Delvigne (marble objects, crystal glasses), Samuel Accoceberry (mirror, rug), Cléo Joffre and Cardew Bonniot (dinnerware).
Renault SYMBIOZ demo car: The Development
The SYMBIOZ demo car was developed simultaneously alongside the SYMBIOZ concept car at the ‘Garage’, a dedicated collaborative workspace at the Technocentre in Guyancourt, France. This project comprised cross-functional teams from engineering and design. It also included extended teams bringing partner technology and creative industry leaders together in an ‘open innovation’ approach. Groupe Renault highly values this form of collaborative working. More about Open Innovation can be found on our website here
Six “open innovative” partners
The six core partners involved alongside Renault teams in the development of SYMBIOZ demo car provided input in their specific areas of expertise:
- LG has been involved in the development of the human-machine interfaces
- Ubisoft has provided on board virtual reality experience for autonomous driving mode
- Devialet has developed a new user experience through advanced sound system
- Sanef has worked on the way the car communicates with road network infrastructure
- TomTom has contributed with its geo-positioning expertise
- IAV has provided autonomous driving engineering expertise
How did we develop this platform? A mule story!
The Renault SYMBIOZ demo car was designed on a special EV platform. How did our engineers develop this platform? In fact, it all starts with a mule…
- The chassis was developed on a test mule named Road Runner, which was one of the three test mules used for the prototype. The many hours of testing allowed the engineers to ensure a high level of comfort, handling and reliability before other components were fitted to the SYMBIOZ demo car.
- Since the vehicle platform was conceived from the outset to accommodate an electric drivetrain, the position of the motors and batteries was optimised in order to deliver:
- A maximum cabin space with no transmission tunnel. The rear-wheel drive system also enabled the front seats to be brought forward.
- A dynamic drive thanks to a lower centre of gravity and optimum weight distribution, including the battery.
- Safety, in order to minimise roll and limit the onset of understeer while driving.
Renault SYMBIOZ demo car shows what will be possible tomorrow by offering an experience now. Alongside some interior and exterior styling elements, the technologies featured in this vehicle are an example of what could also appear in the Renault range over the next few months and years.
- Autonomous drive features will be progressively deployed in Renault’s range under the name ‘Renault EASY DRIVE’.
- The first model to come out in 2019 will offer Level 2 driving automation, offering assisted driving "eyes-on" on motorways and in peri-urban areas.
- Cars with Level 4 “mind-off” driving automation will come starting in 2022, pending government regulatory approvals.
- Some examples of connected services and new-generation motoring will be rolled out cross the range under the ‘Renault EASY CONNECT’ name, in conjunction with the new MY Renault smartphone app.
On October 6th, Groupe Renault announced Drive The Future, its new 6-year plan aligned with its vision of sustainable mobility for all, today and tomorrow. By 2022, Groupe Renault will offer:
- 8 pure electric vehicles and 12 electrified models to continue to lead in electric vehicles,
- 15 AD models benefiting of Renault-Nissan-Mitsubishi scale effect and technologies,
- 100% connected vehicles in key markets.
