Acronyms that definitely require a definition

What does VW TSI and TFSI stand for?

Nothing makes you feel like you’re a part of something like knowing all the jargon, in the same way that not knowing leaves you feeling completely left out. The automotive industry can be particularly guilty of this, despite the fact that mass-production indicates that things should be easy on you, the consumers. We can’t control other brands, but we can clear things up for those shopping VW. Engines like the TSI, sometimes called the TFSI, are just the start of it, as we’ll dive into vehicle names and various features that are often abbreviated.

Common VW and automotive abbreviations

The below list doesn’t just represent definitions common for VW, though some are unique to the brand, but a variety of different acronyms you might come across.

ABS: Anti-Lock Braking System, which prevents wheels from locking up.

ACC: Adaptive Cruise Control, which uses the same forward collision sensors to sense when a car in front is moving slower than your car, and adapts the speed to retain a safe following distance.

AWD: All-wheel drive, which is mechanically different from 4×4. You’ll likely see other variations like FWD (front-wheel drive) or 2WD (two-wheel drive).

DRL: Daytime running lights are lights that remain on at all times to help increase your visibility to others.

GTI: Grand Tourer Injection, or Gran Turismo Iniezione, for the Golf GTI, a hot hatchback that’s a performance version of the Golf. Not to be confused with the Jetta GLI, or Grand Luxe Injected.

Mk: When looking at older model years, you’ll see this abbreviation quite a lot, as in the MkIII Golf. Mk is short for “mark” which is another term for a generation of a model. Each generation represents a design, and a completely redesigned model represents a new generation of that vehicle. The current model year Golf is the MkVII, the seventh generation, and it was redesigned for the 2015 model year.

MQB: You’ll be seeing more of this acronym, as it’s the name for the new VW platform for a variety of models. It literally stands for Modularer Querbaukasten, but in English we call it the Modular Traversal Toolkit.

TSI: As promised, what’s the TSI? The TSI engine isn’t a fancy name, but a descriptive acronym. A gasoline-powered engine, it simply stands for “turbocharged stratified injection.” The turbocharged forces air into the cylinders to more efficiently burn fuel. Stratified injection means that the fuel is injected into the cylinder before injection, so this forced air and fuel meet at the same time for a more efficient design. The extra F in TFSI simply stands for fuel, rather than a different engine type.

These are some of the top acronyms for VW, but we’re sure there are plenty more. If you run into one that confuses you, let us know and we’ll add it to the list. Otherwise, be sure to check back here at the Puente Hills Volkswagen Blog for more posts on all things VW.
