Upcoming Rivian Vehicles May Employ Steering-Through-Wire Control Systems
Rivian, the electric vehicle (EV) manufacturer, is actively developing steer-by-wire (SBW) technology for its fleet of EVs. This technology, already proven in the aviation sector, is slowly making its way into the automotive industry [1].
The SBW system replaces the physical connection between the steering wheel and the front wheels with electronic actuators. Inputs from the driver are translated into digital signals, which are then processed to turn the wheels accordingly [2]. This technology could shrink turning radii for Rivian's full-size EVs, improving maneuverability in tight city streets, parking lots, or off-road trails [3].
The potential advantages of the SBW system include sharper responsiveness and greater design flexibility [2]. Rear-wheel steering could also be integrated alongside steer-by-wire, benefiting larger models like the R1T pickup and R1S SUV [3]. This combination could make these vehicles more nimble in tight spaces.
Rivian's job postings suggest that SBW is a critical technology for its future vehicles. A Senior Staff Technical Program Manager role involves overseeing the SBW subsystem from concept to launch, including supplier coordination, quality control, and reporting to investors [4]. Another job listing for a Sr. Mechanical Design & Release Engineer - Steering mentions both steer-by-wire and rear-wheel steering [5].
As of now, Tesla's Cybertruck is the only production vehicle in North America using steer-by-wire, while Lexus plans to launch one soon, but it has yet to enter production [6]. The introduction of SBW on a more affordable model could help cut manufacturing costs for Rivian [7].
The upcoming R2 crossover, scheduled for a 2026 release, could debut with Rivian's steer-by-wire system [1][3][5]. This timeline aligns with industry norms, as implementing new steering systems with safety as a priority typically requires two to three years [1].
In summary, Rivian is developing its own steer-by-wire technology, which could significantly change how its electric vehicles handle and feel on the road. The SBW system, along with potential rear-wheel steering, could help Rivian differentiate itself in a crowded EV market. The R2 crossover is expected to be the first model to feature this technology, with a possible debut around 2026.

- The steer-by-wire (SBW) technology, currently being developed by Rivian for its EV fleet, is initially inspired by its use in the aviation sector, moving steadily towards the automotive industry.
- With steer-by-wire technology, Rivian could potentially reduce turning radii for its full-size electric vehicles, enhancing maneuverability in urban settings, parking lots, or off-road environments.
- By integrating rear-wheel steering alongside steer-by-wire, Rivian's larger models, like the R1T pickup and R1S SUV, could become more agile in tight spaces.
- The SBW system, along with potential rear-wheel steering, could aid Rivian in differentiating itself within the competitive electric vehicle market, making its vehicles more nimble and offering a unique driving experience.
