 ## Introduction
 
-This is a Power-Split Hybrid Electric Vehicle (HEV) model in Simscape,
-suitable for the system level simulation of
-longitudinal vehicle behavior as it runs faster than real time.
+This is an Electric Vehicle model in Simscape,
+demonstrating some new festures of the recent releases
+of MATLAB®
+and featuring Subsystem Reference which enables
+modular physical modeling workflow.
+
+As an application, this release includes
+an abstract Power-Split Hybrid Electric Vehicle (HEV) model
+with a simple rule-based controller
+for speed tracking simulation.
+For more engaged uses in automotive applications,
+it is recommended to use dedicated toolboxes such as
+Powertrain Blockset™.
+
+The included abstract model is suitable
+for the system level simulation of
+longitudinal vehicle behavior
+as it runs faster than real time.
 The model consists of components such as motor, engine,
 power-split device, and so on,
-and it is built in a modular manner using Subsystem Reference
-demonstrating a workflow where components are built and tested
-individually and also they can be easily integrated into
+and they are built in a modular manner using
+Subsystem Reference and Simscape™ Product Family
+demonstrating a workflow where

+and also they can be easily integrated into

 The HEV model and its components are managed in
-a MATLAB® project and
+a MATLAB project and
 some components come with their own test setups.
