Autonomie 2 Gasoline in details - Featherweight and effectiveness

This high prototype on leg does not pass unperceived. Its hull is from the same mould as the higher hull of Autonomy 1 and has a flat bottom. This allows him a fall of 30% of frontal surface compared to Autonomie 1, and thus a fall of the aerodynamic resistance of the same order of value.

Mechanics includes/understands, one-cylinder engine STIHL gasoline 4 strokes 31 Cm3. Worked again and developed with the bench, it is now equipped with an electronic injection.

This vehicle designed in 2002 for the race at the BASIC price (1) uses in fact of conventional materials. Autonomy 2 thus has a frame out of tubular steel lattice, modified in 2004 it is now more compact thus lighter and rigid.

The vacuum glass fibre hull laminated is a model of the kind only 4 kg (15 kg for that of Autonomy 1) thanks to the use of a very effective manufactoring process which required a very significant development.

Weight ratio/rigidity, This one is very interesting for a vehicle concourrant for the price BASIC, a true exploit, only 45 kg for this prototype having a steel frame.

It has a nose gear and of an aluminium direction. The 3 wheels lay out of rims mixed aluminium/complex triangulated out of glass fibre.
