Listen - 06:39 Aventurin Red is a chef's-kiss-dot-gif color. Steven Ewing/Roadshow The BMW M550i xDrive is 90% of the car the M5 is, and in some ways, it's actually better. The M550i offers strong V8 power and a long list of tech and creature comforts. What it lacks in outright track-attack ferocity it more than makes up for with greater overall balance and a much nicer ride quality. Given the choice, I'd pick the M550i as my daily driver.
