I have seen the Audi A7 on our road a few times. It was pretty sight to behold. During these encounters, the C pillar of the vehicle reminds me of a much more humble car – The 1992 Toyota Corolla liftback. Not only that, both have a ducktail-like boot. When I was young, I always find the Corolla liftback an attractive design among the commonly found notchbacks. The similarities between the 2 cars sparked a question in my mind on the originality of coupe-like sedans.
My curiosity inspired me to do some research on the internet. My research leads me to the term ‘fastback’, which is defined as a car body style whose roofline slopes continuously down at the back. 'Fastback' was first recognized as a definition by Merriam-Webster in 1954. Some of the early days 4-door fastback include the Tatra T87 (1936-1950) and the Citroen CX (1974-1990).
And there you got it, the term “4 door coupe” is merely a modern day term for a 4 door fastback. Therefore, a 4 door coupe design is nothing groundbreaking but is brought back to popularity by the first generation Mercedes CLS. It goes to show that old school rocks!
