RON means Research Octane Number. Sorry forgot about the chemistry already.
But anyways here's what it means for the engine. You see most people say that higher RON means more firepower. In fact it kinda means the opposite. The higher RON, the more energy it needs to make it ignite.

So therefore when you have a high compression engine, a higher RON will not make the fuel pre-ignite(knocking) because it takes more energy(more compression) to make it ignite. Higher RON also means a more progressive ignition. It is best to use RON97 (your engine supports it right?) and not lower than 92. 97 releases the engine's full potential because the engine senses less knock and adjusts the best spark timing. Going any higher won't make a significant(if any) difference at all. A 92 RON is safe and cheaper too.

Basically aspect ratio is the percentage of the tyre's width. 75 means the height of the sidewalls is 75% of your tyre's width.

Oh and regarding TS' question, does a V engine reduce fuel consumption. No.
It has the same fuel consumption and performance of a normal inline engine or any other configuration(same displacement and technology of course). The only advantage of it is it is compact in size. It is more complex however.

There's a research on it for heavy trucks. In traction control, the brakes are applied automatically and adequately to prevent wheelspin. Mercedes Benz S-Class has an Automated Braking System. The car brakes by itself. Yes.
ABS can also mean Antiblockiersystem (German), anti-skid brake system.
There are many meaning to the abbreviation ABS and all of them are correct.

Torque is basically the twisting motion that's happening to the cranshaft.
To put it a little simpler:
Imagine if you want to loosen a nut, you need a spanner right?
Okay when you are loosening the nut with the spanner, what motion do you use? What do you do with your hand when handling the spanner? You make a circular motion with the spanner by pushing/pulling the other end of the spanner right? So basically you applied torque to the nut.

For engines, just replace the spanner with a crankshaft and your hand with the a piston.

To calculate torque, the formula is: force x distance(from the point where the force is applied to the centre of the axis of the crank, sorry if explanation is a bit blur. )
The longer the crank, the more torque you produce. Also the more force you apply, the more torque as well.

Oh thanks dstl1128, forgot to mention the stroke .

BMW's VANOS means:
Variable Nockenwellen Steuerungi
