Porsche’s intense rivalry with Nissan over Nurburgring lap times may have cooled off in recent months, but a new rivalry appears to be in the works, this time with Cadillac and the CTS-V. A report emerging from Germany today has the Panamera Turbo lapping the Nurburgring in 7:56 minutes – just over 3 seconds faster than the American uber-sedan.

It would also mean taking the mantle as fastest lap time for a production sedan, since the CTS-V holds that title now. Porsche hasn’t confirmed the time reported by Sport Auto, nor has it released its own times for the car, so it will remain to be seen if this is the final word.
