2015 BMW M5 - Information and Photos
The 2015 BMW M5 supersedan continues the march of a new era for BMW's hallowed high-performance M (for Motorsport) division. Historically, M cars were powered by naturally aspirated, race-inspired engines with high redlines, such as the previous M5's V10, but in these miles-per-gallon-minded times, turbo engines are all the rage. That's largely why the current M5's engine is a lower-revving, twin-turbocharged V8. Instead of being a one-off design for M duty, it's essentially an amped-up version of what you'll find in the cheaper 550i.
