Bentley's exploits in high-speed ice driving are well-known--and officially recognized. But for Nissan of Europe, the official Guinness certification apparently wasn't as important as going flat-out on Lake Baikal in a bone-stock GT-R.

You see, the claim made with this video is for the unmodified production car ice speed record. Bentley's ice speed record runs were made in a specially-modified "ISR," (Ice Speed Record) Continental Supersports model, in the hands of Finnish rally champ Juha Kankkunen. Top speed: 205 mph.

Not long after, another Finn, Janne Laitninen, piloted an Audi RS6 to a top speed of 206.1 mph on ice.

Now, the Nissan GT-R, in the hands of Roman Rusinov, has crossed Lake Baikal's gorgeous crust of ice at a speed of... 183 mph.

That's not nearly as impressive as the cars modified to hit top speed on ice, but on the other hand, it looked like one hair-rising ride in a showroom-stock street car.
