It's called delta wing because the wing is shaped like the Greek letter delta: Δ.

Delta wing is the swept back wing design seen on jet airplanes like the Concorde.

It is also a race car used in Le Mans in 2012.

The delta wing has the ability to fly at higher speed because the barrier formed by the accumulation of air particles at the leading edge of the wing is evaded. Most of the wing is ahead of the barrier and thus the ability to fly better at higher mach numbers.
