Our solutions : Optimisation of the external aerodynamics of land vehicles

Do you want to optimise the external aerodynamics of your vehicle? Whether in the wind tunnel or using digital flow simulations, our teams have the resources and expertise needed for the successful completion of your projects:

– Design of mock-ups for use in the wind tunnel

– Manufacture and fine-tuning of mock-ups

– Wind-tunnel tests

– Initiation and follow-up of tests

– CFD developments together with analyses, advice and the design of aerodynamic features

From series cars through HGVs and utility vehicles and on to non-standard vehicles, our scope of activity covers the entire spectrum of road vehicles. Whether your vehicles are subject to WLTP or VECTO, we are able to measure the aerodynamic savings they achieve with respect to the applicable standards.

Make sure that the range of phenomena studied is as representative and complete as possible by taking advantage of our wind tunnel with its rolling road which simulates ground contact effects and allows the wheels to rotate.

Our wind-tunnel team is flexible and happy to develop customised solutions. They will examine your requirements and, if necessary, modify the facility as needed for the conduct of your tests.

You can perform your wind-tunnel tests within an affordable budget thanks to our facilities and their limited running costs.

You can rely on our team of designers, all of whom are highly experienced in the use of wind-tunnel measurement techniques. If you wish, they will design and produce mock-ups that combine precision, repeatability and modularity at a reasonable cost.

By working in close cooperation with you, our teams will do everything they can to propose aerodynamically optimised geometries that satisfy regulatory constraints and meet your cost and manufacturing requirements.

Our areas of expertise


Coming from the world of motor sports and based in the technology centre of the Magny Cours circuit, the Aero Concept Engineering team is deeply immersed in the automotive world. From motor sports to series production, along with the world of non-standard vehicles, ACE has contributed its expertise to numerous automotive projects.


Our engineers have been involved in aeronautic projects for many years. They have studied certified aircraft, ultralight aircraft (ULMs), drones and even airships using CFD techniques or in the wind tunnel.


Since HGVs, construction machinery and agricultural machinery are subject to aerodynamic and thermal problems very similar to those affecting passenger cars, our teams are regularly called upon to work in these fields.


Pantographs, landing doors, carriage doors, train tunnel entries, crossings, air conditioning… These are just a few examples of the railway-related topics that we have been asked to address.


Are you responsible for the construction of a new district or a new building? Do you want to make sure that the aeraulic and thermal issues are dealt with prior to the construction work? Then please contact us!


Whether earthbound or airborne, armoured or not, take advantage of our experience to optimise the thermal and aerodynamic aspects of your military vehicles.

Sports and Records

Make your entry into the world of ultimate performance thanks to our sports-dedicated entity aeroptimum.fr. Our aerodynamic engineers will help you get the very best out of your machine and open the way to records, medals and victories!


Research has been one of our sectors of activity for many years. With our wind-tunnel tests, the design of mock-ups and our expertise in CFD, we have cooperated in the preparation of many theses and dissertations.
