Naming convention of old diesels

Post by VisaGTi16v »

Whilst discussing (read bickering) with my friend via email he was on about how my old Visa diesel was a 1.7
Now it was the 1769cc engine as fitted to the bx etc but why on the visa and bx was it badged as 17RD. Using the standard method of rounding off numbers, 1.750 or higher rounds up to 1.8 so therefore 1.769 rounds up to 1.8, why did citroen go the other way? :)

Maybe so the (uninformed) driver thinks "hmmm....this goes well for a 1.7....its just as quick as a 1.8 Pug, and that Rover .....must buy another of these Citroen things"

heh that would only work comparing with other diesels. My friends mk3 escort estate 1.1 petrol was as quick as my visa diesel! That car was great on the M4 though going from sussex to Bristol for uni, foot to the floor it would do 85-95 whole way, didnt need to think, in my zx it was far too easy to go madly over the limit. One trip I had a great 'race' with a 1.6 Orion diesel most of the way down the M4. He would go past me on the flat but every hill I went back past him. This continued for about an hour lol

It's the only engine I've known to be rounded down. Audi's 2144cc 2.2 and Talbot's 928cc 1 Litre Sunbeam are two rounded up examples I can think of.
The Rover 218 was a 1905cc in non-turbo form and 1769cc in turbo. Did Pug ever include the engine size of the XUD in their model names?

BL used to give different names to the same motor!!
The 1275 A series could be either 1275, as in the 1275GT mini, or a 1300, as in the Austin 1300 and its myriad variants.

they still do! the 316 compact went from 1.6 to 1.9, and a 323 is 2.5!

The BMW was the 316, it came with 1798cc engine. Had one great went like stink but threw a piston at 70mph on the way home from work. As for the diesel models being smaller in the shown room compared to the petrol equivelent. My dad told me (30years ago now) that this was to get around post war (2ww) taxes. After the war pertol was cheaper than derv so as to get the car industry back up and running. We didn't need lorries because of the yanks leaving us loads of petrol engine 5.5 and 10 ton trucks. Derv on the other hand was taxed quite heavly and so manufactures went for a smaller engine size by name not cc. So beating the jolly old tax man (hahahahah!!!). This seems to have stuck with the likes of Rover etc.

yeah, why did bmw do that? It was an obvious system they had before -325, is 2.5 litre etc. Why be awkward?
Also for the Rovers, 217 (1769) and 219 (1905) would have sounded a bit stupid I think.
