Traction Control:

An electronic brain which works in tandem with ABS which detects when one drive wheel is spinning faster than the other/s and sends a signal to the engine to reduce the torque by cutting the ignition.


The width between the wheels. The front track can sometimes be different to the rear track.


The engine’s incoming charge of air and fuel is pressurised by an exhaust driven turbine for more efficient filling of the cylinder which produces greater power. The turbocharger is fitted in the exhaust system and is driven by the exhaust gases as they leave the engine. The engine’s incoming air is routed through the turbocharger which increases the air pressure for delivery to the engine’s intake manifold where it is mixed with fuel delivered by the fuel-injection system. Turbo charging is preferred on small engines because it doesn’t use up any of the engine’s power, but turbocharged engines can suffer from a delay in power delivery known as turbo lag.

Turbo Lag:

The delay in response from and engine after the driver presses down on the accelerator. Because the turbocharger is located in the exhaust system a small amount of time is lost while the exhaust gases flow through the engine and reach the turbocharger, so the engine feels slow in response while the turbo is catching up to the driver’s needs.

Tyre Inflation Pressure:

The pressure in a tyre. The recommended tyre pressure can be found on a sticker either in the glove box or on the passenger side front door pillar. It can also be found in the owner’s manual.

Tyre Tread:

The area of the tyre that makes contact with the road. The tread’s function is to remove water from the tyre’s contact patch for better grip on the road.

Tread Wear Indicators:

Bars running across the tread moulded into the tread grooves that are hidden until the tread wears down to a dangerous level when they’re exposed to indicate the tyre is worn out and should be replaced.
