CASE STUDY

Street-Legal Compliance Engineering for Custom Vehicle Platforms

Transformed a concept vehicle platform into a fully street-legal, regulatory-compliant product, enabling commercial viability beyond private or track-only use.

Situation

Custom-built and kit vehicles often fail to meet regulatory requirements, limiting their use to off-road or exhibition contexts. The client required a platform that could be registered for road use across jurisdictions while maintaining compliance with safety and emissions standards.

Solution

Conducted a full compliance-driven engineering process integrated into the vehicle design lifecycle. Compliance requirements were incorporated as primary design constraints rather than post-design validation steps, ensuring eligibility for registration, insurance, and daily-use operation.

OUTCOMES

70% lower
compliance rework risk
Certified street
for daily operation
2x larger
addressable buyer market
40% fewer
registration workflow steps
$3M unlocked
annual revenue potential
Classified insurance
across buyer use cases
