What Do 45 and 63 Mean in AMG Mercedes?

If you have ever noticed the AMG 45 or AMG 63 written on the back of a Mercedes, you may have been left confused—what do these numbers, signified by these acronyms, actually mean?

The numbers 45 and 63 in AMG Mercedes reflect the various types of engines and the level of performance of the engines. In simple terms, the more the number, the stronger the car. The AMG 45s are sporty and swift, whereas the AMG 63s are highly powerful, luxury and brute in nature. These two are built by AMG, which is the high-performance Mercedes-Benz group.

Bringing this one back to the basics and thinking of it as a car enthusiast or a curious mind, here is how it can all be explained.

What is AMG?

Among the numbers, it is worth knowing what AMG means in reality. The AMG full name is Aufrecht, Melcher and Grossaspach, the names that are associated with the establishment of the company. Nowadays, AMG is a performance division of Mercedes-Benz, and ordinary cars become high-performance monsters.

A Mercedes with AMG written on it is a car that has received improvement in practically all areas, like engine work, suspension, styling, exhaust and brakes.

AMG 45: Goodbye to Space. The AMG 45 is the Clever One

One of the smallest models of AMG is AMG 45, though this detail should not be taken as deception. These are powerful cars.

• Engine: 2.0-liter 4-cylinder turbocharged
• Power: about 382–416 horsepower
• Examples: Mercedes-AMG A45, CLA45, GLA45
• Drive: Usually 4MATIC all-wheel drive
• 0–60: About 4 seconds or less

To Whom Is It Addressed?

These AMG 45 vehicles are wonderful for those drivers who desire a performance car that is small, fast, and useful. They are quite famous with younger aficionados who desire to enjoy AMG performance at non-AMG 63 prices.

Big Engine, Big Power: AMG 63

Now it is time to discuss the AMG 63. Such a badge equates to high-level AMG performance and provides a commanding V8 in most cases.

• Engine: 4.0L twin-turbo V8
• Power: 577 to more than 600 horsepower
• Examples: Mercedes-AMG C63, E63, G63, S63
• Drive: Many of them are 4MATIC+ AWD
• 0–60: 3.3 to 4 seconds

Who Is It Aimed At?

The AMG 63 cars are modeled to suit people who seek heavy power and luxury, and a sense of driving on the road. The cars tend to be more imposing, boisterous, and thuggish compared to their AMG 45 brother. They are suitable for those who desire to have supercar power with a luxury car husk.

So Why the Numbers?

And here is the neat thing. One would have expected that the numbers (such as 45 and 63) would have a direct connection with the size of the engine. This was the case previously, but not anymore.

The 63 on the older models Mercedes denotes Mercedes-Benz 6.3 liters back in the days, however, the current AMG 63 hatch is of 4.0 liters V8. The figures are more representative today. They are the level of performance and not engine size.

Therefore, with an AMG 45 with the 2.0L engine, and a 63 with the 4.0L, it is more about brand hierarchy rather than the size of the engine.

AMG 53 and Others: Halfway House

You could also find AMG 35, AMG 43 or AMG 53. They range in-between the entry-level Mercedes and the full-blown AMG 63s.

For example:

• The AMG 53 line models feature a mild-hybrid turbo inline-6 engine.

They provide some performance along with comfort, and they should be attractive to those who desire a relatively quick car, yet do not desire the full-blown power (or price) of a 63.
