What does MR mean?

[LaSpencer]

MR stands for "Middle Engine, Rear Drive", which means "mid-engine, rear-wheel drive", also known as "mid-rear drive", and is one of the driving forms of two-wheel drive vehicles. Here is some additional information: Advantages and disadvantages: The biggest advantage of MR is obviously the even axle load, which provides a very neutral handling characteristic. The disadvantage is that the engine takes up space in the cockpit, reducing space utilization and practicality. Therefore, most cars that adopt MR are sports cars that pursue handling performance. Examples include the Ferrari 458, Ferrari 488, Ferrari LaFerrari, Lamborghini Huracán, McLaren, etc. Mid-rear and front-mid: A mid-engine car places the engine behind the cockpit and in front of the rear axle, which is called mid-rear. Such sports cars do not have a trunk; instead, they have a front trunk, and the engine cover is at the rear. Mid-rear-drive supercars offer great driving pleasure and excellent handling. There is also another layout called front-mid. Front-mid-engine cars are relatively rare, and the Mercedes-AMG GTR is an example of a front-mid-engine car.
