Topic:

I think we will be the last generation of drivers with performance petrol cars.

All the new technology is moving toward, electric cars cars that drive themselves...

I wonder what my kid will be driving in 20 years time, maybe I should store a Citi golf for him/her....:)

LOL about citi golf!

I dont mind electric cars, as long as they are powerfull

Look at that Tesla, id kill for 1 ,

Still do love my petrol engines!



Speaking of petrol engines, need a new car man! have a 2007 honda civic 1.8 vxi , getting way too slow for me now! done 40000kms with it and its getting stale! LOL

want a honda s2000 or a lotus elise, but at the moment i cant as im in a 1 year contract for FIFA and dont think its wise to purchase such a expensive car not knowing where my income will come after the world cup! :( woe is me! lol

They should make some sub forums for this Motoring section.

Maybe one for VAGs & Lancia or something like that.
They can call it VAG & Lancia Pride :p

there is not going tobe any oil left in the future! lol

But ya, watched a docu a while basicaly saying the US goverment stoped electric cars or something to that effect cause they would loose money on oil etc

Who knows though, i personaly believe it!

Anyone watched Zietgiest! crazy stuff man! crazy! - personaly i also believe it, i might be gullable, but it does make sense !

excuse my spelling! working and foruming at the same time! LOL

Electrical cars wont need petrol to run, so petrol companies wont have anything to do = loss of jobs.

But then again, advantage for the consumer

I've got tons of topics but mostly favouring the Alfa's and lambasting the VW's!

I'll post some more threads for you fanboys soon!

In hot weather the air pressure in CT is 800mbar. It is usually 800mbar in JHB.

Why do cars have an altutude sensor/why do tuners have different altitude maps?

At a fixed pressure a cubic foot of air should have the same number of 02 molecules?

Even more so on a turbo car where the car fuels on MAP (manifold absolute pressure) which at, say, 2000mb (1000mb boost) just means the turbo has had to add a little bit extra to compensate, but 2000mb on the MAP at the coast is the same as 2000mb on the MAP at the Reef?

Most of the tuners have different ECU maps for altitude and coast - usually because they say there is less air pressure and therefore less oxygen at altitude. (This is also the reason we get lower octane at the REEF (sorry!).)

On fuel injected cars there is often a sensor called a MAP (manifold absolute pressure) which measures the absolute air pressure in the manifold. On normal cars this is often the same as the ambient air pressure. On a turbo car this is the ambient air pressure plus the boost pressure. But the turbo can just work a little harder and make up the difference (if there is any to start with in the 1st place) - so why the different maps?

While the Tesla shows what can be done, it's still not at a stage where it's as practical and convenient as a petrol car. Thrashing it around will give you about a 100km range, and everyday driving should give you about 300km. And it takes far too long (16 hours!) to recharge.
