Next-generation vehicles

Definition (what it is)

Next-generation vehicles (NGVs) are road vehicles across passenger, commercial, and special-purpose segments that combine electrified propulsion (battery-electric, hybrid, and hydrogen fuel cell), software-defined electronic architectures, pervasive connectivity, and varying levels of automated driving with lightweight, high-performance materials. They deliver step-change improvements in energy efficiency, safety, performance, user experience, and lifecycle sustainability relative to conventional internal-combustion-engine vehicles. The term typically encompasses battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), fuel cell electric vehicles (FCEVs), connected and automated vehicles, and software-defined vehicles.

Key technical characteristics

  • Electrified propulsion and energy storage: Compact e-axles (motor, inverter, gearbox), regenerative braking, onboard chargers, and DC/DC converters. High-energy-density lithium-ion batteries (e.g., LFP, NMC/NCA), with solid-state, lithium-metal, and sodium-ion chemistries under development. Fuel cells (proton-exchange membrane stacks) and high-pressure hydrogen storage (350/700 bar) for FCEVs. 400–800 V (and higher) system architectures to reduce current and enable fast charging.
  • Power electronics and electric machines: High-efficiency inverters and chargers using wide-bandgap semiconductors (silicon carbide, SiC; gallium nitride, GaN), advanced packaging (DBC/AMB substrates), and liquid cooling. Motor topologies include permanent-magnet synchronous (including rare-earth-reduced designs), induction, axial-flux, and switched-reluctance machines; hairpin windings and torque-vectoring for performance and efficiency.
  • Electrical/electronic (E/E) architecture and software: Centralized compute with domain/zonal controllers, high-speed in-vehicle networks (Automotive Ethernet, CAN FD, LIN), real-time operating systems and middleware, and over-the-air (OTA) software and firmware updates. Secure boot, hardware security modules, and data logging for diagnostics and continuous improvement.
  • Connectivity and cloud integration: 4G/5G telematics, Wi‑Fi/Bluetooth, and vehicle-to-everything (V2X) communications via DSRC or cellular V2X to support cooperative safety, traffic efficiency, and infrastructure coordination. Cloud services enable remote diagnostics, fleet management, energy services, and feature deployment.
  • Automation and ADAS: Sensor suites (cameras, radar, lidar, ultrasonic, inertial measurement units, GNSS) with sensor fusion and AI-based perception, prediction, and planning to deliver functions from SAE Level 1 driver assistance to Levels 2–4 automated driving, plus driver monitoring and fail-operational/fail-safe strategies.
  • Thermal and energy management: Liquid or two-phase cooling for batteries, motors, and power electronics; heat pumps and cabin preconditioning; battery preheating/cooling for fast-charge durability; thermal runaway mitigation and propagation-resistant pack designs.
  • Lightweighting, structures, and aerodynamics: Multi-material bodies using advanced high-strength steels (AHSS), aluminum and magnesium alloys, and fiber-reinforced polymers (CFRP/GFRP); structural adhesives and tailored joining; large structural die castings; low-drag designs with active aerodynamics and low rolling-resistance tires.
  • Charging and refueling: AC and DC fast charging (e.g., CCS, North American Charging Standard/NACS, CHAdeMO), plug-and-charge (ISO 15118), and wireless inductive charging in some applications. Bidirectional power (vehicle-to-grid/home/load, V2G/V2H/V2L) for grid services. Megawatt Charging System (MCS) for heavy-duty vehicles. Hydrogen refueling protocols for FCEVs and, in some markets, battery swapping.
  • Safety and cybersecurity: Functional safety (ISO 26262), Safety of the Intended Functionality (ISO 21448), cybersecurity engineering (ISO/SAE 21434) and regulatory compliance (e.g., UNECE R155 for cyber and R156 for software updates). High-voltage isolation, pyro-fuse protection, crash energy management, and battery safety standards (e.g., UN 38.3, UL 2580).
  • Sustainability and lifecycle: Life-cycle assessment-driven design; low-carbon and recycled materials; critical-mineral strategies (reduced cobalt/nickel content, rare-earth-free motors); modularity and repairability; second-life use of batteries; and end-of-life recycling (pyro-, hydro-, and direct recycling).

Relevance (why it matters in modern EV design)

  • Higher efficiency, range, and performance through advanced batteries, power electronics, lightweight structures, and aerodynamic optimization.
  • Faster, more durable charging and improved thermal control to enhance usability and total cost of ownership, especially for fleets.
  • Enhanced safety via robust ADAS/automation, connected safety services, and rigorous functional safety/cybersecurity engineering.
  • Continuous feature and quality improvements through OTA updates and data-driven development, enabling software-defined value over the vehicle lifecycle.
  • Grid and ecosystem integration with smart charging, V2G/V2H, and energy-services participation, supporting renewable integration and load balancing.
  • Progress toward sustainability and regulatory targets by reducing tailpipe and lifecycle emissions and improving material circularity.

Typical materials, components, and manufacturing methods

  • Body-in-white and closures: AHSS (including press-hardened steel), aluminum sheet/extrusions/castings, magnesium castings; mixed-material joining (structural adhesives, self-piercing rivets, flow-drill screws, laser welding, friction stir welding). Large structural high-pressure die castings (“gigacastings”) in some architectures.
