Rivian, an electric vehicle manufacturer, has released information about the first of its Electric Adventure Vehicles the R1T, an all-electric, 5-passenger pickup. The automaker will introduce its fully electric SUV, the R1S along with the R1T to the public on Nov. 27, at AutoMobility LA.
The highly anticipated truck features a range of up to 400+ miles, a wading depth of 1 metre, and the performance and precise control of quad-motor AWD and has been developed to help customers get out and explore the world. The R1T and R1S will be produced at Rivian’s manufacturing plant in Normal Il, from late 2020.
The foundation of the R1T and R1S is Rivian’s skateboard platform, which efficiently packages the battery pack, drive units, suspension, braking and thermal system all below the height of the wheel, leaving the space above for occupants and their gear.
Beyond the packaging benefits, this architecture delivers a low centre of gravity that supports the vehicle’s agility and stability. Adding to these inertial advantages is a sophisticated suspension architecture with unequal length double wishbone suspension in the front and a multi-link suspension in the rear. The suspension features dynamic roll control and adaptive dampers along with ride-height adjustable air-suspension – allowing the suspension to be adjusted for highway comfort, on-road performance or off-road capability.
Rivian’s vehicles also feature a quad-motor system that delivers 147kW with precise torque control to each wheel, enabling active torque vectoring and maximum performance in every situation, from high-speed cornering to low-speed rock crawling. With 3,500 Nm of grounded torque per wheel (14,000 Nm of torque for the full vehicle), the R1T can reach 60 mph in 3 seconds and 100 mph in less than 7 seconds. This powertrain and chassis also enable the R1T’s tow rating of 11,000 pounds.
“The beauty and elegance of our quad-motor setup isn’t just about brute power; this architecture provides instantaneous torque with extremely precise control at each wheel, which is completely game-changing from a dynamics perspective, both on- and off-road,” said Executive Director of Engineering and Programs Mark Vinnels.
Rivian’s energy-dense battery module and pack were developed with the most demanding journeys in mind — incorporating tough underbody protection and an advanced cooling system to give occupants the confidence to go further, regardless of terrain or temperature. Adaptive control algorithms learn driver behavior, optimising user-specific battery management for maximising battery life, reliability and second-life reusability. Three battery sizes are planned, with the 180 kWh and 135 kWh available at launch and a 105 kWh being made available within six months.
The battery is designed for fast charging with charging rates of up to 160kW. This enables approximately 200 miles of range to be added in 30 minutes of charging. In addition to DC fast-charging, an 11kW onboard charger facilitates rapid charging at a Level 2 charger.
Rivian has developed its connected car platform from a clean sheet to allow full control and flexibility over the vehicle hardware, software and user experience. The system operates on a high-speed Ethernet backbone that enables robust security. This platform supports granular over-the-air updates of vehicle software to enhance functionality and improve performance.
All Rivian vehicles connect to a cloud-ecosystem for data exchange and processing, enabling machine learning and data services. The digital experience extends beyond the vehicle into the cloud ecosystem and mobile/web applications and provides a consistent and seamless interface for vehicle status and control.
The in-vehicle experience consists of a custom 15.6-inch centre touch screen, 12.3-inch instrument cluster and a 6.8-inch rear touch screen. Understanding its customers desire for connected adventure, Rivian developed maps, music, navigation and other adventure-focused features to complete the digital experience.
The R1T will launch with a robust hardware suite with multiple modalities including camera, lidar, radar, ultrasonic and a high precision GPS coupled with high definition maps. This hardware enables “Level 3” (hands-off wheel and eyes off road) autonomy for highway operation. Beyond the highway Level 3, the vehicle will have a range of self-driving features focused on enabling active lifestyles.
