In 1988, BMW wedged an engine loosely derived from the company's 1970s M1 supercar in a commonplace 5 Series sedan. Ever since, the M5 has been the quintessential sports sedan: a seemingly ordinary luxury car that delivers extraordinary performance on the autobahn.
A third-generation M5 brought V8 power in 1999, and a fourth generation in 2006 introduced the thunderous V10 with more than 500 horsepower. In its current fifth-generation iteration, V8 power has returned to the M5—but it's now twin-turbocharged to return 560 horsepower and mated to a dual-clutch transmission to deliver lighting-quick shifts.
Despite its astonishing performance, the M5 remains a five-passenger luxury sedan with almost as many gadgets as the Pentagon. The M5 truly is truly the family man's—or woman's—supercar.
