Renault Alpine A110-50 Concept – Car Body Design

Renault Alpine A110-50 Concept – Car Body Design.

Continuing my interests in car up skirts photos, I peeked into one of the anticipated design from a french automaker; Renault.  The car that makes my heart aflutter is the Alpine concept car.

If you look at the broadside it was supposed to be as close as possible with the 2012 Renault Megane and its iteration from Renaultsport.

Like many arm chair browsing artist, I used major search engines to find some pictures of the frame of the current production car against that of the concept car.

Renault Megane Chassis

What you see is totally different.  While the production car is mostly pressed metal plates welded or screwed together, you see it differently on the concept car.  The concept is all bits of tubes held together by either welding or brazing and perhaps glue.

Tubular skeleton of Concept A110-50

The ‘Cup’ chassis is prevalent with anything with Megane RS sitting in the middle.  While searching for more tell-tale pictures, it seems that the hatch chassis is lighter by 25kg.  But of course the bhp on the RS blown 4 pot is double that of the undisclosed name for the normal 4 pot on the pedestrian hatch/sedan Megane.

But the different chassis in engineering used is a well known subject.  It is definitely cheaper to produce tubular skeleton if you only making a handful.  Pressed plate chassis is only economical when there is volume to consume the production.  You cannot discount the fact that when you do change from one offs to volume, there is bound to be trade offs.  In this case it is stiffness.  Something has just got to give.  The tubular cage is indeed a method used to meet intent; marketing.  While the pressed steel chassis is one for the real world.  The majority of commuters do not need the stiffness that enthusiasts yearn for.

No one would even think that this will even go into production as a commuter car.  This is after all; an Alpine.  If you think the RS models were rare, this will be rarer still.
