∪ The symbol ∪ means union. Given two sets S and T, S ∪ T is used to denote the set {x|x ∈ S or x ∈ T}.

## What is E power?

e-POWER delivers a responsive drive with smooth acceleration like an EV. The e-POWER system allows you to enjoy all the benefits of an EV. e-POWER delivers massive torque almost instantly, which enhances drive response and results in smooth acceleration. Also, the system operates very quietly, much like a full EV.

## What does U mean in texting?
