Support when you need it most – the Verification and Validation Framework

Case Study Overview

Guaranteed access to HORIBA MIRA’s heavily-subscribed climatic wind tunnels and electromagnetic compatibility (EMC) test facilities were vital to electric vehicle start-up Tevva during the development of its 7.5-tonne truck.

Early on in the project it became clear that significant delays to the programme could occur if these key facilities and services were unavailable – for instance, if they had been reserved



Support for the project was provisionally scheduled, based on the anticipated test and development requirements. Time, for instance, was pre-booked in the climatic wind tunnel at HORIBA MIRA’s Nuneaton facility to ensure access.

As with all projects conducted under HORIBA MIRA V&V frameworks, flexibility is key. Although based loosely on a pre-booked schedule, there were no penalties for cancellation or deferment. Instead, Tevva held dates using the framework agreement and had first refusal if other manufacturers requested the same dates.

A pragmatic governance process was put in place to control expenditure. Within the framework, extra services could be authorised immediately in response to changing situations. If, for instance, a vehicle in the wind tunnel required electrical engineering support, this could be provided on-site without waiting for an additional purchase order to be raised, which is often too late.

The end result was a highly agile process, with priority access to key facilities such as HORIBA MIRA’s climatic wind tunnel, Advanced Battery Development Suite, XiL test beds and EMC testing. This minimised the potential for delays, provided peace of mind for the project and gave the most value from the HORIBA MIRA ecosystem.

Successes and benefits

HORIBA MIRA’s flexible V&V frameworks offer:

  • Priority access to the HORIBA MIRA vast range of service, including pre-booked slots in heavily-subscribed facilities.
  • Rolling contract with the freedom to expand capabilities covered within the framework.
  • Flexibility to divert funds from the framework to other HORIBA MIRA capabilities to cover unexpected contingencies.
  • No financial penalties for cancellation or deferment.

OEMs and startups need to move quickly. This framework provides heads of department with a direct link to HORIBA MIRA, allowing them to authorise work immediately with a simple signature, knowing that all the paperwork is already in place.
