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. If you found this post worthwhile, you can get a parallax view at Cars In Depth. If the 3D thing freaks you out, don’t worry, all the photo and video players in use at the site have mono options.

    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.

  • Jeff S Corey--We know but we still want to give our support to you and let TTAC know that your articles are excellent and better than what the typical articles are.
  • Jeff S A sport utility vehicle or SUV is a car classification that combines elements of road-going passenger cars with features from off-road vehicles, such as raised ground clearance and four-wheel drive.There is no commonly agreed-upon definition of an SUV and usage of the term varies between countries. Thus, it is "a loose term that traditionally covers a broad range of vehicles with four-wheel drive." Some definitions claim that an SUV must be built on a light truck chassis; however, broader definitions consider any vehicle with off-road design features to be an SUV. A [url=]crossover SUV[/url] is often defined as an SUV built with a unibody construction (as with passenger cars), however, the designations are increasingly blurred because of the capabilities of the vehicles, the labelling by marketers, and electrification of new models.The predecessors to SUVs date back to military and low-volume models from the late 1930s, and the four-wheel drive station wagons and carryalls that began to be introduced in 1949. The 1984 [url=]Jeep Cherokee (XJ)[/url] is considered to be the first SUV in the modern style. Some SUVs produced today use unibody construction; however, in the past, more SUVs used body-on-frame construction. During the late 1990s and early 2000s, the popularity of SUVs greatly increased, often at the expense of the popularity of large [url=]sedans[/url] and station wagons.More recently, smaller SUVs, mid-size, and crossovers have become increasingly popular. SUVs are currently the world's largest automotive segment and accounted for 45.9% of the world's passenger car market in 2021. SUVs have been criticized for a variety of environmental and safety-related reasons. They generally have poorer fuel efficiency and require more resources to manufacture than smaller vehicles, contributing more to climate change and environmental degradation. Between 2010 and 2018 SUVs were the second largest contributor to the global increase in carbon emissions worldwide. Their higher center of gravity increases their risk of rollovers. Their larger mass increases their stopping distance, reduces visibility, and increases damage to other road users in collisions. Their higher front-end profile makes them at least twice as likely to kill pedestrians they hit. Additionally, the psychological sense of security they provide influences drivers to drive less cautiously. the above definition of SUV any vehicle that is not a pickup truck if it is enclosed, doesn't have a trunk, and is jacked up with bigger tires. If the green activists adhere to this definition of what an SUV is there will be millions of vehicles with flat tires which include HRVs, Rav4s, CRVs, Ford Escapes, Buick Encores, and many of compact and subcompact vehicles. The green movement is going to have to recruit millions of new followers and will be busy flattening millions of tires in the US and across the globe. Might be easier to protest.
  • Sckid213 I actually do agree that most Nissans are ultimately junk. (I also think many BMWs are also). I was talking challenging the 3 in terms of driving dynamics. Agree all were failures in sales.
  • THX1136 More accurately said, we are seeing exponential growth in the manufacturing capabilities in this market. Unless, of course, all those vehicles are sold with customers waiting until more a produced so they can buy. Indeed, there are certainly more EVs being purchased now than back in 2016. Is demand outstripping manufacturing? Maybe or maybe not. I sincerely don't know which is why I ask.
  • ToolGuy The page here (linked in the writeup) is ridiculously stupid, seriously stupid, e.g., A) Not sure that particular Volvo is killing the planet as quickly as some other vehicles we might choose. B) A Juke is "huge"??? C) The last picture shows a RAV4 Hybrid?
