I would call this a three-quarter coat. I only buy that length as I always wear trousers and don't much like a long coat. I do think the one in the picture is only just about long enough to qualify though.
I'd wear a coat on top of a jacket, so as I wouldn't wear something over this I call it a coat. Length is immaterial to me. I wouldn't wear it as I don't want a coat where my bum freezes if I sit down outdoors, and because anything padded or quilted will end up with me reassembling Bibendum AKA the Michelin man!
I recently bought a jacket - in black corduroy with a grey fleecy lining. It's quite short and definitely a jacket. Soon I am going to buy a coat - possibly a pea coat or a duffle coat, I'm not entirely sure yet. That will be a longer length garment. As someone who is on the reasonably tall-ish side (183cm) I find some jackets look quite short on me if I get them in a fitted size, so I often buy the next size up. This means I get the length I want but not the fit.
I would call it a jacket because I always think of a coat as being longer & usually more formal. Having said that the car coat has always been this length, as has the pea coat & if I owned one I would probably say that I was getting, taking off or wearing 'my coat'. Blimey, I can't decide but I'm the person who wears a snowboarder shirt & calls it a jacket...
It looks the same as the TSV and the reviews on the QVC website make interesting reading as the majority of them give it 1 or 2 stars.
I'll own up to having bought the TSV because I wanted a slightly longer jacket than the ones I have. It arrived very quickly but was returned within half an hour of its delivery.
I've got a couple of Centigrade jackets already but, despite ordering my usual size, the sleeves were too tight and I'd have to take it off to drive which defeats the point of having a coat for the winter.
I've also submitted a review to go with the dozens that had the same problem as I did.
Whether it's deemed a coat or a jacket it's definitely a "fail."
