Building Functional Concept Vehicles

Technical overview: pre-integrated EV chassis for concept vehicle development.

EV Skateboard Platform at Detroit Battery Show 2025

Building a functional concept vehicle typically requires full powertrain development — battery management systems, motor controllers, vehicle dynamics software, and safety validation. This document outlines how a pre-integrated rolling chassis eliminates these dependencies.

SECTION 01

Functional vs Static Concept Vehicles

Static concept vehicles — non-functional display models — limit validation to visual assessment only. Functional concepts enable dynamic testing: suspension geometry under load, thermal behavior during operation, NVH characteristics, and real-world ergonomics evaluation.

A drivable platform provides measurable data points: 0-60 acceleration curves, regenerative braking efficiency, weight distribution with body-in-white, and power consumption under various drive cycles. These metrics inform production feasibility studies.

02

Power Distribution

12V auxiliary and high-voltage taps for lighting, HVAC, displays, and custom electronics

03

Mounting Points

Standard bolt patterns for body attachment; CAD files provided for integration modeling

04

Drive-by-Wire

Steer, throttle, and brake inputs via electronic interface; no mechanical linkages required

Traditional Development Constraints

Ground-up EV development requires parallel workstreams: high-voltage battery architecture, BMS calibration, inverter tuning, thermal management loops, CAN bus integration, and functional safety certification (ISO 26262). Timeline: 18-36 months minimum.

For concept vehicles with limited production intent, this engineering overhead is prohibitive. The result: most OEMs default to static mockups with simulated lighting and non-functional drivetrain components. Design validation becomes theoretical rather than empirical.

SECTION 03

Pre-Integrated Rolling Chassis

The Olympus platform ships as a validated, road-ready skateboard chassis. Battery pack, drive unit, power electronics, vehicle control unit, and drive-by-wire systems arrive pre-integrated and calibrated. Body mounting points accept custom superstructures via standard bolt patterns.

Use Cases

OEM Concept Programs

Decouple body development from powertrain timelines. Test multiple body variants on a single validated platform without redundant EV engineering.

Design Studio Prototypes

Deliver functional vehicles to clients without in-house EV expertise. Platform handles propulsion; studio handles industrial design.

Film & Production Vehicles

Hero cars with actual driving capability for on-set use. Eliminates tow rigs and CGI for driving sequences. Repeatable performance for multiple takes.

Engineering Validation

Dynamic load testing, aerodynamic validation, thermal imaging under operation, and ergonomics assessment with actual vehicle motion.

Frequently Asked Questions

Stage display or fully drivable — what are the options?+
Both. The platform ships fully drivable (130 kW, 121 mph capable), but can be configured for static display if that's all you need. Most clients start with stage demos and enable full driving capability for customer experiences or validation testing.
What body materials work with the platform?+
The 3,550 lb payload capacity supports composite panels, fiberglass, carbon fiber, aluminum, and steel body constructions. Most show car materials work without modification.
How quickly can a concept car be built?+
Platform delivery takes 6-12 weeks. Body development depends on complexity, but show car bodies typically take 8-16 weeks. Total time from order to drivable concept: 4-7 months.
Can the concept later become a production vehicle?+
The Olympus platform is production-ready. A concept built on this foundation can transition to limited or full production without platform redesign.
Can the platform handle multiple show appearances?+
Yes. The platform is built for repeated use — transport between venues, drive on/off stages, run customer demo rides. Modular components allow field service if needed between events.
How does the platform integrate with custom lighting and displays?+
The platform provides 12V and high-voltage power outputs for custom lighting, interior displays, and show-specific features. Your design team can integrate any visual elements without worrying about power supply or electrical architecture.
What happens if something breaks during a show?+
The platform uses modular components designed for field serviceability. Critical parts can be swapped quickly. We also offer event support packages for high-profile reveals where downtime is not an option.
