GEVCO Engineering Summary & Concept Feasability

This summary report is intended to capture the key items and issues identified during the GEVCO Phase1 regarding the overall feasibility of the vehicle concept and the main technologies to be applied. The layout closely reflects that of the report issued by the GEVCO/MIRA team at the end of the phase1, but has been summarised or reduced in a number of areas to provide the reader an informed insight in to the workscope and deliverables in a reduced format.To capitalize on the growing demand for electric and alternative, fuel-efficient vehicles, two concepts are to be developed and offered on a global basis, these being a city car and a mid range family vehicle. The Phase 1 study developed the concept of the small vehicle intended primarily, but not exclusively for urban use. This is called the iMav. The larger vehicle is only discussed in terms of the technology differences with the smaller product.

Visual Concepts

A series of targets were established prior to the start of the programme which would be challenging to deliver and would ensure that i-Mav would be one of the most technologically advanced and visually exciting EVs developed, incorporating technologies that would make it an exciting and viable alternative to conventionally powered vehicles.The project had a clear focus regarding the ‘GenY’ user group and their needs driving the requirement to design more than just another Electric Vehicle, it was to deliver a commercially viable technologically advanced vehicle that would be desirable and fun to drive reflecting the lifestyle and social values of the iPod generation, delivering a step-change in the way society views personal mobility.

Mulitplatform Development

The concept study was structured to ensure a solid technical foundation on which to progress to the next phase of the project by developing the vehicle technical and design concept, and identifying existing and near future technologies and appraising their suitability for application. To meet the challenges of achieving the targets and drivers established a philosophy adopted by the GEVCO/MIRA team during the 6 month programme was simple; to design and engineer a vehicle from the ground up for electric traction with a clean sheet approach regarding all aspects of the vehicle, ensuring the application of best practice in applying the new EV technologies without inheriting constraints from legacy based compromises on ICE vehicles.

The result is that the i-MAV incorporates new technologies never before seen on a production vehicle including: an electro-magnetic drive motor removing the need for a gearbox, reducing cost and complexity, a unique metal air battery with significant cost and technical advantages over conventional lithium based solutions and a cutting edge structure and body concept to meet the requirements of future legislation and NCAP safety standards.

The outline designs and engineering schemes presented demonstrate a positive basis on which to progress to the next phase of the programme and ensure informed decisions can be made on the vehicle strategic and technical direction. A significant number of strategic technical options have been appraised during this phase based on good engineering knowledge and general product cost data. To ensure that the correct strategy for technology application is made, further work is required to develop the cost model with supplier input.
