British journo and avid racer Chris Harris takes a more serious look at two of the fastest road cars money can buy: the Nissan GT-R and Porsche 911 Turbo.

However, we’re not talking about run-of-the-mill models here but rather the more extreme versions of both cars.

In the case of the GT-R, Harris is testing the recently launched ‘Track Pack,’ which is currently offered exclusively in Japan and the UK.

And for the 911 Turbo Harris is testing the sportier Turbo S model, the latest version of which was first launched in 2011.

Unfortunately, weather conditions meant the day’s driving was a little more subdued than we’re used to from Harris. It also didn’t help that he was complying with fan requests to drive a little more sensibly than usual, which turns out to be duller in the end.

Nevertheless, Harris raises some good points in contrasting the two cars. Go ahead and click play to find out which one he’d rather own.

The vital stats for each of the cars, starting with the Porsche 911 Turbo S is an output of 530 horsepower and 516 pound-feet of torque, which is sent to all four wheels via a seven-speed PDK dual-clutch transmission. The 0-60 takes just over 3.0 seconds and top speed is 195 mph. The GT-R Track Pack brings 545 horsepower and 463 pound-feet of torque to the table, as well as a six-speed dual-clutch transmission and all-wheel drive. It has a blistering 0-60 time of just 2.7 seconds but, as Harris points out, doesn't offer much over a standard GT-R despite costing significantly more.
