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.

The Other Car

MyTrajet

People Mover! I hear you shout.  Truly agreeable with you on that one.  It is NOT a car.  Its a bus.  Initially it was an embarrassing idea to have one.  Yet I have a family with three above average size children with above average appetite.  Plus we used to have a lived in maid from Indonesia.  Therefore, it is a must have.  It is a Hyundai Trajet GLS circa 2002 but we bought it in 2004.  The only automatic transmission car that I own.  My wife actually owns it.  I just pour in the fuel and pay the monthly dues and do all the maintenance on it.MyTrajet

A bit of history.  Hyundai made this to compete against the Toyota Estima, Honda Oddysey and the GM/Opel Zafira.  Wherever they meet.  I would think Asians would be the preferred market as the Europeans are dead set on station wagons.  Aisans tend to have a sizeable family extended or not.

It drinks a lot.  Petrol I mean.  Wherever you go except for national highways which seem to be just about ‘ok’.  The fuel consumption is a real issue when it does not travel in one huff.  Stop and Go traffic is stressful on the heart and the wallet.  It does not have a fuel consumption meter.  Which makes it hard to guess how efficient it is at doing its thing.  However, big lugs like this are the ones that supposed to get the highest attention.  Reducing fuel consumptions on behemoths should be the main focus of car designers.

Therefore, in the spirit of chasing efficiency, I plugged in the washing machine hose thingy into the airbox.  Drilled an M25 hole and simply push it in.  The other end with the funnel could be placed anywhere.  So I did.

The Trajet's turn

Secondary Intake for Hyundai Trajet

I had it go through various orifices.  I had to remove the front grille to make my hand accessible to where I want it.  I then decided to run it through the bottom grill.  I found this not to be the ideal place.  The wake from the bumper would have a slight pressure drop where I had it.  It ws a bit lengthy and would cause some measure of pressure loss.

Since then I had cut it up and placed it just over the left light cluster.   What I do want to see is using a snorkel and mount it right over the radiator.  That would be Trajet Snorkel 2.0

I still have no clue if there was any improvement.  I leave that one to faith.

MAA seeks longer feed-in tariff period for hybrid cars

MAA seeks longer feed-in tariff period for hybrid cars

I am going to do this like Tun Dr. Mahathir in point form.  The Hybrid car in Malaysia is a pet peeve of mine.  Why is this so?  Reasons

  1. As I have calculated the Total Cost of Ownership of a hybrid defeats it purpose in subsidized petrol land of Malaysia.  A hybrid’s price, even after the 0% tax that it gets, is so expensive, that it would take 28 years to get back the savings on a similarly petrol engined car2012 Honda Comparison
  2. The Fuel Consumption on the CivicHybrid does not look much better than my Satria Neo R3 does it?  The Civic Hybrid uses a 1.5cc engine mated to motors.  Yet it cost 50% more.  The top 3 in the comparison list has the same capacity engine of 1.5litres.  It seems the more you save; the more you pay.  What’s the bloody point?
  3. Any battery will not last forever. Rechargeable or otherwise.  Be it car batteries, mobile phones, tablets.  You name it.  If the warranty for an auto battery that you shelved USD3,000 for is for 5 years.  It would have estimated to have 7 years of life.  The warranty period is always the safest bet for any manufacturer.
  4. This makes it that after 7 years of ownership, either you sell it off to the next punter, or buy new batteries.  Either way, the 26 years Return on Investment just got longer.
  5. It sucks.  Has anybody driven one?  Because the battery is big, huge and heavy either
    • Its too long or
    • Its too cramped or
    • Its an SUV which is an moronic reason for a hybrid
  6. If you really want fuel savings AND reduce carbon emissions; its LPG.  There is more subsidy for cooking fuel than it is for transport.  That’s the main reason why there is no LPG cars in Malaysia.  The subsidies will be enormous.  But they sell the Persona Ecologic in the UK where LPG is not subsidized.  And it makes bloody good sense.
  7. Bankers of the World have been asking Malaysia to reduce its subsidy on fuel.  This is (allegedly) reduce the public from unrealistic low cost of living.  Apparently they are not too happy that life in Malaysia is much cheaper.  This is yet another lie for European automakers to sell their diesel here.  Nobody here likes diesel because they remind us of old cramped Bus Mini that we used to depend on to get outselves to and from work.  Well ask them to reduce their subsidies on veggies and they’ll shut up.  About the only thing that stopped the World Trade Organization from coming to a common agreement.
  8. Adam Smith; “People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public.”  That is what the MAA is.  Malaysian Automotive Association.  In many known worlds such a collaboration of the Automotive Industry is illegal.  Its known as ANTI COMPETITION.   I’d will it to be dissolved.  We all know there’s only one real Malaysian manufacturer.  The other is a proxy for a foreign maker.  While the rest are all selling somebody else’s car.  Assembling is NOT making.  MAA only stands for the benefit of selling more cars which ‘ends in a conspiracy against the public‘.  Of which this is it.  I am so amazed that nobody has taken this seriously.

LISA – Free/Affordable Finite Element Analysis Software

Screens

LISA – Free/Affordable Finite Element Analysis Software.

LISA is a mathematical program to calculate and show various effects on a material. The calculation method is known in engineering as Finite Element Analysis. Its breaking up a piece of material into smaller and simpler planes. It then calculates this parts individually. It then compares the part next to it and applies the same calculation method again.

LISA comes as a free download for calculations based on up to 1300 nodes, or points of calculation. I intend to play around and get familiar with it. Then I can think of using it somewhere in the near future.  The main area where I think I should be looking into is the front suspension arm of the MacPherson strut.  This seems ambitious for the moment as I would actually need to get hold of one.  I would then need to take measurements off it and buid the model in LISA.

Lessons from Porsche owners

RSR engine mount bar – Page 2 – Pelican Parts Technical BBS.

I had the idea of reducing more weight.  A lot of my friends just dumped something like RM 2,000.00 for a factory Carbon Fiber unit and the claimed savings was about 7kg.  I doubt it very much.  I have carried it myself.  Its bulky and the strength to hold it was more spent on trying to get it balanced onto the mountings.

I have found this picture from a Porsche owner forum.  It started off a plans to change engine mounting of a rear wheel drive car.  This was impressive.  The model itself is pretty light and powerful.  What drew my attention was the work done on the bonnet (or hood for you Americans) of the engineless front of a car.  A car which is honestly light in the first place yet was known to be slap happy around the bends.  So a lighter front end seemed to be the last thing you would want?

Cheezing a Hood

I think its important to leave untouched the material close to hinges as the weight will transfer on it before reaching the hinge.  This hood above may be light but its also shaky.  I especially hate moving bonnets at high speed.

Lightening of Hinges

Ford Escort front bonnet hinge mechanism

Some lightening works done on a Ford Escort.  The pictures with the holes seem to come from the front bonnet hinge, back bonnet hinge and wipers.  Interesting.  Some of this could not be implemented in our car as the current design does not use so much material.  Especially the hinge for the hatch.  Nevertheless, it gives some ideas of what people go through to make their cars lighter.  Suddenly I feel vindicated

Rear boot hinge lightened and quite possibly sand blasted by the look of it. Off a Ford Escort

Hinges seemed obvious targets as the are typically thick.  In design, they need to provide rigidity when the bonnet/hood/hatch is moved.  The two hinges provide a movable point and bears the load.  Thefore, rigidity and stiffness is a requirement.  If we look at door hinges, they are the more thicker and bulkier of the rest.  The load is entirely on them until the door is closed.  When a door is closed, the load is shared around the door sill and not on the hinge alone.

What I have done on my car much earlier was removal of the hinges and made more holes.

Hinges Before After

The lightening work was not as extensive as the top two.  The M6 bolts on the top hinge were replaced with Pro Bolts Aluminium ones while the bottom was a Titanium one.  I chose Ti rather than another Aluminium as I was worried that the torque was insufficient against the aerodynamic force on the top bonnet.  So the Ti bolt gives me the ability to tighten it up, whereas if it was Aluminium,  I could easily damaged the thread of the bolt.

DRB-HICOM mulls ‘Asian Car’ project

DRB-HICOM mulls ‘Asian Car’ project.

This is a momentous occasion.  Not just due to the high profile idea.  Its huge because it means a lot to us in the region.  Its awesomeness is in the fact that someone bought this idea, toys around with it between a few local directors, made a decision and issues out a media statement.  Just think about it.  It is innovative even just thinking about it.  Let us ponder a moment of what a car is.  It is a means of transport and for the vain; a status symbol.

History

Throughout the world, there were foreign auto makers knocking on each country’s door.  The Japanese were the earliest to penetrate and be successful at it. Primarily as Asia was a market for industrial equipment.  Seemingly these marques delivered reliable products.  That is how brands grew back in the good ol’ days.  Branding activities were not so active.  In late 90′s foreign car makers set up shop in Thailand to produce cars meant for the regional market consumption.  Nissan even had made an ASEAN car which was conceived as the Nissan California or known here as the AD Resort.  Honda had their City.  It was only later that Toyota moved the production of the Corrolla to Rayong.  The Thais singled out the Corrolla to become the national taxi.  At the same time they built their Kijang in Indonesia and became a well accepted product.  Ford-Mazda came in late 1996 and produced pickup trucks.  They tried the old Japanese route; selling agriculture workhorses.  The Thais in their ingenuity, like the robustness of the pickup but hated its ride.  So they decided to do things on their own.  Workshops chopped and dropped the ride down to car levels.  They made roofs for the back and plugged in side facing seats.  In the 90′s Toyota changed their lineup from the mid market Corolla to produce lower rung Tercel.  Before the Vios sedan was introduced, the mini MPV Avanza was widely marketed through Thailand, Malaysia and Indonesia.  Indonesia with its highly populated cities on mainland Java, were bombarded with vans and mini MPVs.  To this day, it remains the biggest market for people movers.  They are used extensively for long distance travel.  Toyota now has a stranglehold on the MPV market in Indonesia through their subsidiary Daihatsu.

While Thailand became the “Detroit City of the East” automotive enthusiasts in Malaysia blame local government policies for hindering our chance at securing these FDIs.  I cannot understand that.  If you are a car fan, why does it matter if production was your neighbour.  Unless you are a car salesman.  You would think having production closer means lower buying cost and bigger margins and/or commission.  People have a misconception about Pricing.  It was back before the Reagan administration that people used to make a car within costs and adds margins ontop of the cost and therefore sell it at that price.  Nowadays, its backwards.  People think about the margins that they want, pick a price that people pay, and then work out the cost to make.  This reaches beyond just automotive products.  With the exception of Financial Services or, if I wanted to be rude; Bankers.

Thailand as a country, sells as much as it buys.  It makes 24% than Malaysia does.  But it has 300% more people than Malaysia.  It has a bigger market size than Malaysia.  But the general population is poorer.  Does not look good.

Indonesia as a country, makes 200% than Malaysia does. But it has 800% more people than Malaysia.  It has the biggest market size but the general population is much poorer.  Does not look good.

The region is home to a lot of foreign industries as they realize the need to be close to the market also gives them lower production costs as we are not stringent with labour and environmental rules.  Therefore you get a lot of FDIs in the region.  But they ensure that profits are repatriated back to their homeland in the guise of foreign income.  They could transfer profit into these countries and get taxed lower than if they keep it home.  The attraction has always been not just the brick-mortar kind.

But production of somebody else’s trade rights does not make your country rich.  Yes, it provides work.  But workers don’t elevate themselves in terms of salary more than profit for a few does.  Neither do they gain any effective knowledge.  The longer one stays on the FDI dependence, the longer it is to get economic independence.  If you look at the figures for Thailand, Indonesia and Malaysia, guess which one is the poorest?  Detroit of the East.  Have you seen what the actual Detroit looks like nowadays?
