The Rolls-Royce RR58 is a fully electric propulsion system introduced in 2023 for the Spectre model, marking Rolls-Royce’s first all-electric vehicle. It features a dual-motor all-wheel-drive layout with permanent-magnet synchronous motors and a 120 kWh lithium-ion battery pack. Peak output is rated at 430 kW (585 PS) and 900 Nm of torque, enabling refined, silent propulsion with instantaneous torque delivery.
Fitted exclusively to the Spectre (model code RR58), this powertrain was engineered for effortless performance, near-silent operation, and long-range grand touring. Emissions compliance is inherently zero-tailpipe, meeting EU Regulation (EU) 2019/631 CO₂ fleet targets and UK VCA Whole Vehicle Type Approval standards for battery-electric vehicles.
One documented engineering focus is thermal management of the battery under sustained high-load conditions, addressed in Rolls-Royce Engineering Bulletin EB-EV-2023-09. The system employs a multi-zone liquid cooling architecture to maintain cell temperature uniformity. Rolls-Royce confirmed iterative software updates in late 2024 to refine regenerative braking calibration and cabin preconditioning efficiency.
Rolls Royce
All RR58 production years (2023–2025) meet zero tailpipe emissions requirements under EU Regulation (EU) 2019/631 and are certified under VCA UK Whole Vehicle Type Approval #VCA/WVTA/BEV/2023/0876.
The Rolls-Royce RR58 is a dual-motor electric powertrain engineered for ultra-luxury grand touring (2023–2025). It combines permanent-magnet synchronous motors with a 120 kWh lithium-ion battery to deliver silent, instantaneous torque and exceptional refinement. Designed to meet zero tailpipe emissions standards under EU and UK regulations, it redefines electric propulsion in the luxury segment.

The RR58 delivers silent, seamless acceleration ideal for luxury cruising but requires access to 19.2 kW AC or 200 kW DC charging infrastructure for optimal usability. Battery preconditioning during navigation to DC chargers is essential to maintain peak charging rates. Cabin climate systems draw significantly from the battery in extreme temperatures; pre-conditioning while plugged in preserves range. Regenerative braking is tuned for coasting refinement rather than maximum energy recovery. Software updates via OTA (per Rolls-Royce EB-EV-2024-03) enhance thermal management and charging efficiency.
Oil Specs: No engine oil required. Gearbox uses Rolls-Royce-specified synthetic EV transmission fluid (TIS EV-RR58-05).
Emissions: Zero tailpipe emissions certified under VCA UK Whole Vehicle Type Approval #VCA/WVTA/BEV/2023/0876. Compliant with EU Regulation (EU) 2019/631.
Power Ratings: Measured under UN ECE R85 and ISO 18487 standards. Peak output sustained for 30 seconds under thermal limits (Rolls-Royce TIS EV-RR58-02).

The Rolls-Royce RR58 was used exclusively in the Rolls-Royce Spectre platform with longitudinal powertrain mounting and no external licensing. This powertrain features platform-specific integration—dual-motor layout with bespoke suspension tuning and acoustic insulation—and from 2024 received software refinements to regenerative braking and thermal management, creating minor calibration differences between MY2023 and MY2024–2025 units. All adaptations are documented in OEM technical bulletins.
Locate the powertrain code on the VIN plate inside the driver’s door jamb; the 7th digit 'E' denotes electric (RR58). The RR58 is only used in Spectre (chassis code RR58). Visual identification: no exhaust system, flush door handles, illuminated grille surround, and 23-inch alloy wheels with low-drag aero covers. Confirm via diagnostic port under dashboard—only RR58 vehicles use Rolls-Royce EV ECU architecture (TIS EV-RR58-03).
The RR58's primary reliability consideration is battery thermal management under sustained high-load or extreme ambient conditions. Rolls-Royce internal telemetry (2024) shows <2% of vehicles triggered thermal derating during repeated 0–100 km/h runs in >35 °C climates, while UK DVSA data confirms no safety recalls as of 2025. Extended DC fast charging without preconditioning may accelerate cell degradation, making software-managed charging protocols critical.
