About Rear mid-engine, rear-wheel-drive layout

In automotive design, an RMR, or rear mid-engine, rear-wheel-drive layout is one in which the rear wheels are driven by an engine placed with its center of gravity in front of the rear axle, and thus right behind the passenger compartment. Nowadays, such cars are more frequently called 'RMR', to acknowledge that certain sporty or performance-focused front-engine cars are also referred to as "mid-engine", the main engine mass being located behind the front axle. Until the early 1990s, RMR-layout cars were just called MR, or mid-engine, rear-wheel-drive layout), because the nuance between distinctly front-engined vs. front mid-engined cars often remained rather vague.
