What does MR mean in automotive terms?

[HectorDella]

MR in engines stands for mid-engine rear-wheel drive. Drive: Mid-engine rear-wheel drive refers to the layout where the engine is positioned between the front and rear axles. The biggest advantage is obviously the even weight distribution, resulting in very neutral handling characteristics. The downside is that the engine occupies cabin space, reducing space utilization and practicality. Therefore, most sports cars that use MR are those that pursue handling performance. Many cars are mid-engine rear-wheel drive vehicles, such as the Ferrari 458, Ferrari 488, Ferrari LaFerrari, Lamborghini Huracán, McLaren, and so on. In cars with a mid-engine layout, the engine is located behind the cockpit and in front of the rear axle. This is called mid-rear placement. There is also another layout called front mid-engine. Cars with front mid-engine layouts are rare, but some do exist. The Mercedes-AMG GT R is an example of a front mid-engine car. Mid-rear-engine sports cars do not have a trunk. These sports cars have a front trunk, and the hood of such cars is at the rear.
