Rivian shows Electric Adventure Vehicles in LA
Electric vehicle startup Rivian unveiled its highly anticipated all-electric pickup and SUV at events in the lead up to the 2018 LA Auto Show. Collectively called Electric Adventure Vehicles, the R1T is a five-passenger pickup truck and the R1S a seven-passenger SUV. In top spec, the company promises more than a 400 mi (640 km) electric range and a wading depth of 1 m (3.3 ft) for the quad-motor AWD vehicles.
“Starting with a clean sheet, we have spent years developing the technology to deliver the ideal vehicle for active customers,” said Rivian Founder and CEO RJ Scaringe. “This means having great driving dynamics on any surface on- or off-road, providing cargo solutions to easily store any type of gear, whether it's a surf board or a fishing rod and, very importantly, being capable of driving long distances on a single charge.”
The vehicles ride on Rivian's skateboard platform, which contains the battery pack, drive units, suspension, braking, and thermal systems. All of these are kept below the height of the wheels to provide as much space above for occupants and their gear. When combined with a low center of gravity, a sophisticated (for the class) suspension of front unequal-length double wishbones and rear multilinks for better vehicle agility and stability. Dynamic roll control, adaptive dampers, and height-adjustable air-suspension allow the suspension to be adjusted for highway comfort, performance handling, or off-road capability. Ground clearance for the R1S is 205 mm (8.1 in) for kneel/park ground clearance, 245 mm (9.6 in) for aero mode, 285 mm (11.2 in) for standard curb mode, and 365 mm (14.4 in) in off-road mode.
The architecture enables active torque vectoring and “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.
The quad-motor propulsion system is offered in three versions, delivering total vehicle power (at gearbox input) of 300 kW, 562 kW, or 522 kW. Total vehicle torque ranges from 560 to 1120 N·m, with “total grounded torque” from 7000 to 14,000 N·m. The highest performance version has 0-60 mph (0-97 km/h) acceleration in 3.0 s and 0-100 mph (0-124 km/h) in less than 7 s, with top speed of 125 mph (202 km/h).
Fully-equipped vehicles with the highest performance level and largest battery pack will enter production first. Three battery pack sizes are planned, with the 180 kW·h and 135 kW·h available at launch, with the base 105-kW·h variant to follow within 12 months of the start of production.
Those pack sizes equate to ranges greater than 400, 300, and 230 mi (640, 480, and 370 km), respectively. Ranges will be about 10 mi (16 km) greater for the SUV. Fast 160-kW charging rates enable about 200 mi (320 km) of range to be added in 30 min. An 11-kW onboard unit facilitates Level 2 charging. The battery pack features toughened underbody protection and an advanced cooling system. Adaptive control algorithms learn driver behavior, optimizing management for maximum battery life, reliability, and second-life reusability.
Both truck and SUV feature the same strong proportions and clean body lines, short overhangs, high ground clearance, aggressive approach and departure angles, and Rivian’s signature “stadium” headlights and daytime running lights that extend the width of the vehicles. The R1S rear has a combination liftgate and small tailgate, with the tailgate providing an area to sit. The second and third row seats fold flat to provide room for any gear required.
They have the same 2015 mm (79.3 in) width, with mirrors folded. Height is 1815 mm (71.5 in) for the truck, slightly taller for the SUV at 1820 mm (71.7 in). Bigger variances are in length, with the pickup at 5475 mm (215.6 in) and the SUV 5040 mm (198.4 in), and wheelbase is 3450 mm (135.8 in) for the truck, 3075 mm (121.1 in) for the SUV. Vehicle curb weight is 2650-2670 kg (5840-5880 lb), and the gross vehicle weight rating is 3470 kg (7650 lb). Maximum payload is 800-820 kg (1760-1810 lb), and the trailer weight rating is 5000 kg (11,000 lb) for the pickup, 3500 kg (7700 lb) for the SUV.
Engineers were able to leverage the vehicle architecture to deliver more lockable storage than in any other vehicles in their respective segments. The 330-L (11.7-ft3) front trunk is easily accessed with a fully powered (up and down) hood. For the R1T, the lockable gear tunnel aft of the cab extends laterally across the vehicle for more than 350 L (12.4 ft3) of space to haul oversized gear and it acts as a step for loading items into the bed or onto the roof. There is a watertight, integrated tonneau cover for the bed, and beneath the bed floor is a 200-L (7.1-ft3) sealed bin that can also be used to store a full-size spare tire. The bed’s Gear Guard feature uses two integrated locking cables to secure bicycle frames and other gear, and a bed camera can alert owners if the bed or contents are tampered with.
The interior is intended to be a premium environment but invite rugged, daily use, with sustainably sourced wood in a natural finish used as a structural element that integrates the main center display and driver cluster. In the high-wear areas, materials take inspiration from sportswear and active gear.
“The biggest challenge was creating an interior design that delivered a premium experience, while still being comfortable as a space that is heavily used,” said VP of Vehicle Design Jeff Hammoud. “To do this, we looked outside the automotive industry and took inspiration from contemporary furniture, as well as hiking and outdoor gear, to drive the design.”
The clean-sheet connected car platform was engineered for ultimate control and flexibility over the vehicle hardware, software, and user experience. It operates on a high-speed Ethernet backbone for robust security and supports granular over-the-air updates of vehicle software. All Rivian vehicles will connect to a cloud ecosystem for data exchange and processing, enabling machine learning and data services.
A modern in-vehicle experience is enabled by a 15.6-in center touchscreen, 12.3-in instrument cluster, and a 6.8-in rear touchscreen—and Rivian-developed maps, music, navigation, and other “adventure-focused” features.
The company expects that the trucks’ safety systems and body-structure design will deliver IIHS Top Safety Pick Plus and NHTSA 5-Star ratings thanks to eight airbags for occupant protection and skateboard platform reinforcements to protect the battery. The R1T and R1S will launch with a complement of active safety systems and a suite of camera, LiDAR, radar, ultrasonic sensors; high-precision GPS; and high definition maps that enable SAE Level 3 (hands-off wheel and eyes off road) autonomy for highway operation. And a range of other self-driving features are promised.
Pricing starts at $61,500 for the R1T and $65,000 for the R1S, both after the Federal tax credit. Rivian is now accepting preorders for a refundable deposit of $1000. The trucks will be produced at the company's manufacturing facility in Normal, IL, with customer deliveries beginning in late 2020.
