TEOS Powertrain Engineering

The design office of Mecachrome France was transferred in:

TEOS Powertrain Engineering, company created in 2011 and 50% owned by IFP Investment and 50% by Mecachrome. TEOS is a company specialized in engineering of powertrain systems and based in Montigny-le-Betonneux, in Paris region.TEOS Powertrain Engineering develops different kinds of innovative propulsion systems in aeronautics, motorsport and automotive industries.

TEOS offers a large rage of development possibilities starting from a sub-system optimization until a complete project development in order to ameliorate the performances of such engines like gasoline, Diesel or Jet-A1, atmospheric, turbo and hybrid engines, as well as associated transmissions, gearboxes and reducers.


Powertrain engineering:
Engineering, manufacturing, assembling, testing and validation.


  • Automotive (ex: electric reducer for a demo-vehicle Twizy, e-turbo system for luxury sedan)
  • Motorsport (ex: GP2, GP3, Le Mans 24 hours, Formula 1, WRC)
  • Aircraft (ex: project Clean Sky in partnership with Airbus Helicopters and Austro Engine)  
  • Energy (production / recovery)

Center of excellence:

  • High performance engine
  • Innovative and advanced solutions  
  • Best weight / power ratio on the market for pistons engines for aeronautics applications thanks to our patents

A few examples:

GP2 Powertrain 

LMP1 Engine
