Clutchless manual - Basically, the cars electronics does the
clutchwork for you. You don't need to depress a clutch. This usually happens
using the gear lever (push and pull action) or paddles (buttons) on the
steering wheel. This allows the driver to select which gear they're driving in,
without the need to use a clutch. No bunny hopping.

Cylinders - The cylindrical shape in which pistons move and
function. More cylinders generally equates to more power output - and higher
fuel usage.
Damper - Aids shock absorption. The damper controls the
springs, creating a smooth/soft return to normal position after a bump. Bad
damping can significantly impact ride comfort.
Disc brakes - The wheel's disc (a round steel plate in the
middle) spins as the wheel spins. The calipers (which have brake pads attached
to them) close tight on the disc as you press the brake. This slows and/or
stops the vehicle. When brakes (brake pads and discs) are too hot they can lose
grip and fail. Discs are often 'ventilated' (holes drilled in them) to allow
better air flow to keep them cooler - providing maximum braking potential. A
lot of performance cars have ventilated discs.
Emissions - The harmful gases that are produced by your
fosil fuel powered cars. These are measured as the amount CO2 emissions (in
grams) produced per kilometer and they vary greatly depending on the type of
engine. For example a BMW 320d (2 litre, 4 cyl, auto) produces 160g/km compared
to the Ford Falcon XR6 Turbo (4 litre, 6 cyl, turbo manual) which produces
303g/km.
Green Car - A car that produces low emissions and is better
for the environment.
LED - Light-emitting diodes. Light technology now used in
head and tail lights, as seen on Audi, BMW and others. Rather than one big
light, it looks like a number of smaller lights.
Park assist - Assists your parking! Fitted to more and more cars these days, park assist can be invaluable - and a bumper saver. Some systems have sound alone to warn you, others have on screen displays that show you which part of the car you're about to ding. On some cars, the warning noise itself is more annoying than a ding!
