After unveiling the Symbioz concept at this year's
Frankfurt Motor Show in September, Renault is now giving journalists the chance
to climb inside an actual prototype and go for a test drive. This is the first rolling prototype built to be autonomous from the
ground up, setting us up to experience the year 2023, in the present.
Aside from featuring Level 4 autonomous driving
capabilities, meaning you can take your mind off the road, the Symbioz is also
a zero emissions vehicle, powered by two electric motors, and fully connected.
The demo car's two electric motors are located on
the rear axle, and work together with Renault's 4Control all-wheel steering
system, offering improved dynamics on the road. In terms of specs, the
prototype delivers 360 kW (489 PS) and 550 Nm of torque continuously, although
the maximum power is rated at 500 kW (680 PS) and 660 Nm of torque. The result
of that is a 0 to 100 km/h time of 6 seconds flat.
While the prototype features a 72kWh battery back,
the architecture itself can accommodate batteries with a capacity of up to
100kWh. As for charge times, you can juice them up to 80% in less than half an
hour.
The Symbioz measures 4.92 meters long, 1.92 meters wide
and 1.44 meters high, with a wheelbase of 3.07 meters. It's quite a large car,
and thanks to its styling (the vast glazed upper), it will let ample light into
the cabin while optimizing exterior visibility.
Speaking of styling, the exterior has a wide range
of aerodynamic features, such as the vertical air intakes, side wind deflectors
and a roof spoiler (deploys automatically in Dynamic mode). Beneath the design,
you'll find Lidars concealed in the front headlights and rear bumper, radars
and ultrasound sensors behind the bodywork, a front camera, rear camera and
lateral cameras hidden in the door handles.
Inside, there is no center console and the air vent
system has been designed to achieve a flat floor. Meanwhile, storage areas in
the dashboard have been moved to free up space on the sides and the door panels
have been optimized with built-in lighting.
The entire cabin layout of the Symbioz demo car
changes automatically according to which driving mode you've selected. In AD
mode, the steering wheel and dashboard move back 12 cm, while Dynamic mode
offers the driver additional lateral support for a bucket seat feel, while
changing engine, steering and chassis settings. As for Classic mode, that's the
standard mode, where everything is positioned like in a conventional car.
If you want to let the car do all the driving, you
can relax and use the Symbioz's virtual reality experience. Just put on the
helmet and go on a virtual journey. It's important to note that the system
makes sure to reproduce the speed, trajectory, position on the road as well as
the surrounding vehicles in real time so as to provide a comfortable
experience.
According to Renault, the Symbioz demo car was
developed simultaneously alongside the concept car, with partners such as LG
and Ubisoft providing technical expertise. The next step for the French
automaker will be to offer Level 2 autonomous driving in one of their cars in
the year 2019, while Level 4-ready models will appear starting in 2022, pending
government regulatory approvals.
