BOF, IRS, CKD, SUV… Automotive TLAs, What Are Your Most (and Least) Favorite Acronyms?

TTAC’s post by J. Emerson on how so-called Millennials’ automotive tastes have been shaped by their coming of automotive age in an era when their parents embraced body on frame sport utility vehicles brought forth a lot of thoughtful comment. One comment that caught my eye, though, had little to do with the topic of the post but rather was a complaint about the use of the acronym BOF. To most of us that means “body on frame” but to manga or Korean sitcom fans it might mean Boys Over Flowers and when you’re using abbreviations you have to be sure your audience recognizes them. In an earlier life I did IT support and we would make a recursive joke about the proliferation of TLA’s, three letter acronyms. Such acronyms, abbreviations, and jargon serve a useful purpose to those in the know, but can also function as a mark of group identification, a shibboleth, if you will. Sometimes the use of jargon can function as a barrier to others, which can be contrary to how inclusive we want TTAC to be. As a writer I have to realize that not everyone knows all the lingo of being a car enthusiast or industry watcher but at the same time I don’t want to condescend and assume that our readers don’t know about what we’re talking. Partly it’s a matter of following a style manual but it’s also an issue of respecting the readers. When discussion suspensions at a car site is it really necessary to say “independent rear suspension” the first time in a post before switching to IRS? When I’m reading about possible government targeting of tax-exempt groups for political purposes does a site have to write out “Internal Revenue Service” for me to know that in that context IRS has nothing to do with the Porsche 928’s Weissach axle?
Offhand I can think of a few automotive TLAs besides BOF and IRS. There’s the CAN bus I recently discussed, and SLA, short long arm, another suspension term. Getting back to the post that spurred this one, there’s SUV and CUV.
Sometimes, instead of exporting fully assembled cars or setting up full overseas assembly operations with a body shop and local suppliers, a lot of automakers will ship CKD, completely knocked down, kits that are then put together in their foreign markets with local labor (though some sources say that the abbreviation stands for “cars knocked down”).
While researching this post I discovered another related TLA, those fully assembled exported cars are referred to as CBUs, completely built units.
What other automotive acronyms can you think of? Which do you think most car enthusiasts should recognize without explanation? Which do you particularly like to use? Which do you find annoying?Ronnie Schreiber edits Cars In Depth, a realistic perspective on cars & car culture and the original 3D car site.

    The interpretation of "BOF" that I've seen most is from conferences in the IT business, where it connotes sessions for those with a special interest in the same sub-area or otherwise like-minded people: "Birds Of a Feather".

    One of my clients recognises the extent to which their over-use of acronyms has become a barrier to communication and has an "Acropedia" hosted on the company intranet. It helps, up to a point, but discerning the correct translation between 3 or 4 different entries that may make little to no sense can be frustrating.

  • Mia Hey there!I recently stumbled upon the Crack Eraser DIY Windshield Repair Kit (check it out here: and decided to give it a shot on a small chip in my windshield. I have to say, it worked like a charm! Super easy to use, and it saved me a trip to the professionals. If you're dealing with a similar issue, this kit is definitely worth considering. 😊
  • Rust-MyEnemy Whoa, what the hell is wrong with Jalop1991 and his condescension? It's as if he's employed by Big Plug-In or something."I've seen plenty of your types on the forums....."Dunno what that means, but I'm not dead keen on being regarded as "A type" by a complete stranger"" I'm guessing you've never actually calculated by hand the miles you've driven against the quantity of gas used--which is your actual miles per gallon."Guess again. Why the hell would you even say that? Yes, I worked it out. Fill-to-fill, based on gas station receipts. And it showed me that a Vauxhall Astra PHEV, starting out with a fully charged PHEV battery, in Hybrid mode, on my long (234-mile) daily motorway daily commute, never, over several months, ever matched or beat the economy of the regular hybrid Honda Civic that I ran for a similar amount of time (circa 5000 miles)."You don't use gasoline at all for 30-40 miles as you use exclusively battery power, then your vehicle is a pure hybrid. Over 234 miles, you will have used whatever gas the engine used for 200 of those miles."At least you're right on that. In hybrid mode, though, the Astra was using battery power when it wasn't at all appropriate. The petrol engine very rarely chimed in when battery power was on tap, and as a result, the EV-mode range quickly disappeared. The regular hybrid Civic, though, deployed its very small electric reserves (which are used up quickly but restore themselves promptly), much more wisely. Such as when on a trailing throttle or on a downward grade, or when in stop-start traffic. As a result, at the end of my 234 miles, the Civic had used less gas than the Astra. Moreover, I hadn't had to pay for the electricity in its battery.I look forward to you arguing that what actually happened isn't what actually happened, but I was there and you were not."Regardless, that you don't understand it appears not to have stopped you from pontificating on it. Please, do us all a favor--don't vote."You really are quite unpleasant, aren't you. But thanks for the advice.
