Look out, Cadillac CTS-V and Porsche Panamera Turbo, there is a new King of the "śRing. BMW's latest M5 sedan has reportedly completed a single lap of Germany's famed Nurburgring in just 7 minutes 55 seconds.

The Cadillac CTS-V was the first production four-door sedan to ever traverse the Nurburgring's North Loop in under 8 minutes - logging a 7 minute 59 second lap - but the Porsche Panamera Turbo one-upped the Caddy with a 7 minutes 56 second lap. However, both cars have now been knocked down a peg, with the M5 setting the new course record.

At the hands of a BMW factory test driver, the all-new M5 laid down an impressive time of just 7 minutes 55 seconds, no doubt thanks to its new 560 horsepower twin-turbocharged 4.4L V8 engine.

However, the M5 might not remain at the top for long. The more powerful Panamera Turbo S has yet to go round the "śRing and, with 50 horsepower more than the regular Turbo, the S will likely have what it takes to dethrone the new king.
