Honda Civics are a line of cars that were very popular and manufactured by Honda. 
I agree.  Know for being one of the most durable brands on the market today.
They were originally a subcompact but now they are larger and more upmarket. They have moved into the compact car section of the market.
Excuse me I meant Known* for being...  I did not know that about them being a subcompact at first and now moving into compact.  That's interesting.  Sounds like they've gotten larger.
EPA guidelines for vehicle size required a car having combined passenger and cargo room of that of a mid size car.
The EPA is a very important agency.  I hope that it continues to be allowed to do it's job at full capacity.
Initially the Civic had a reputation for being fuel efficient and environmentally friendly. Later iterations have become known for performance and sportiness, in particular the Civic Type R.
That is true.  Later iterations of many vehicles in the early 2000's around the time of the movie Fast and Furious, started getting the Type R tag and similar names.
