I've yet to find out how bad your roads are. Are potholes sharp-edged and more than 100mm deep? There were French cars around from the 1950s-1980s which could handle the most atrocious roads at high speed with little more than a distant thump heard - with little or no movement of the body. French roads in the 1940s and 50s were very, very poor - many English cars which went there apparently never made it back in one piece! Cobbled roads, poor foundations, roads in poor repair with the ravages of six years of war etc. made French suspension what it was. |
Hi Flatout
I am not sure about the dimensions of the potholes but its generally a poorly executed expansion joint on a bridge or the tar between the section of bridge is worn out.
You are doing 120 to 140 kmph on an open straight highway and "bamm" you hit the expansion joint on the bridge.
Or you enter a rough patch of tar and you slow down to about 60 kmph or so and think you made it without downshifting but around the end where the good part starts would be a large undulation of the fresh patch of tar whose height would be too high then again same thing.

I know what you mean about heat getting to you even with the AC on full. This is due to being surrounded by minimally-insulated metal which is radiating heat - a heat which is much more effective than hot air. Cold air struggles, especially when at the relatively low volumes which come through the little vents. I remember some cars being so well ventilated that even in 35C (which is
very hot for a Yorkshireman!) the car's interior remained acceptably fresh. Internal airflow to maximise cooling is something not considered anymore - the engineers assume AC will do the job.
One answer would be to insulate - in Australia and Africa there are Land Rovers and the like with a secondary roof, to keep the rays off. Combined with modern insulation, the situation could be made much more bearable. I wonder if reflective foil would make much difference when the sun is at its strongest? Little can be done with regard to the steep rakes of the modern car windscreen, although I imagine people do cover the large expanse of black plastic dashboard top with light-coloured cotton?
Commuting is an unpleasant form of Western life which the whole world seems to be doing. The internet is slowly changing things, but it is slowly. Long? A poor engine with its noise and vibration tires me after a little more than an hour and a half or 200km. I deliberately didn't specify 'long' - but we all know when a trip becomes a 'long' one. For me, in Northern England, I would call a long journey one which takes more than three hours or which is more than 650km. This is plenty of time for a car's true abilities, or weaknessess, to begin to show themselves. As the brain tires, every noise, vibration, discomfort and inconsistency is multiplied until you can reach the point where even a decent-enough car can feel like a clunker. This is when a genuinely good car begins to shine.
I once drove the six cylinder Mercedes over a long distance, at around 180kmph. It was a warm day. I then transferred to a more modern Audi of similar size and with more power. At first experience the Audi would feel the better car - it feels to respond more quickly, feels more comfortable and feels faster. It flatters the driver - but after half an hour behind the four circles I realised how inferior the whole machine was - it wasn't just me adapting. Although quieter and lower revving, the engine wasn't as smooth, the handling at high speed not as sure, the ride edgy in comparison to the Mercedes', there was much more heat soak from the engine and exhaust, the steering was far less precise, the brakes less sure, all the messages less accurate and with more 'white noise' to confuse and tire. It is under conditions like those when you really begin to see what matters in a car. Both cars were my own and in proper working order.
I'm talking about travel uninterrupted by sleep, I think my longest was about 1200km around England one busy day, collecting items I had bought online, even buying a car. The particular car I was in was good (powerful, responsive engine with high gearing and a turbo to mask the layout of the four cylinders, the suspension the very best and roadholding exceptional) except for one thing - the steering. It grew more woolly and more vague until it began to irritate beyond about 750km.[/quote]
I have driven Maruti Zen, wagon R, Honda city quite a few times on the highway but can tell you heat makes you feel sleepy and tired. The A, B and C pillars generally have a plastic cladding but the main heat ingress is from the front windshield and the other glasses. These glasses actually become so hot you that cant touch them and I am saying this about the glasses having a sunfilm on, and which by the way has been made illegal to be used and hence to be removed.
Now how is the A/C system going to deal with that. Surely it wont.
Of course I have not had the good fortune to drive the premium cars so cannot comment on its behavior.
Placing a light coloured fabric on top of the dashboard reflects on the windshield and is not at all comfortable to the eyes.
Importance of road holding and handling becomes more pronounced on twisty roads and mountain roads. On normal dual carriage highways with long straights and gentle banked bends an average suspension system does the job.
So to sum up my personal opinion driving in hot conditions is the most tiring and all else is secondary.
