Automakers often evaluate the performance of their own vehicles by benchmarking them against competitors. Even a renowned brand like Ferrari keeps a close eye on the supercar market. A spy photographer named Varryx camped outside Ferrari’s headquarters in Maranello and captured footage of the company testing a Porsche 911 GT3 RS and a McLaren Artura. There were also numerous Ferrari models spotted during the testing.

The yellow Porsche 911 GT3 RS gets a lot of screen time in the video. It can be seen driving behind the gates, taking a run on public roads, and returning for further evaluation. The current GT3 RS is equipped with a naturally aspirated 4.0-liter flat-six engine that generates 518 horsepower and is paired with a seven-speed PDK gearbox. Official specifications indicate that the car can accelerate from 0 to 62 miles per hour in 3.2 seconds and has a top speed of 184 mph. The model features active aerodynamic elements at the front and a drag reduction system, and it holds a lap record at the Nürburgring, completing it in 6 minutes and 49.328 seconds.

The blue McLaren Artura makes a briefer appearance in the video. It is seen going on a single outing.

The Artura is McLaren’s first series-production plug-in hybrid car, which sets it apart from the limited-run P1 supercar. It is powered by a twin-turbocharged 3.0-liter V6 engine combined with an electric motor in the transmission bell housing. The only available gearbox is an eight-speed dual-clutch setup. The Artura has a total output of 671 horsepower and 593 lb-ft of torque, allowing it to accelerate from 0 to 62 mph in 3.0 seconds and reach a top speed of 205 mph. The car also features a 7.4-kilowatt-hour battery that provides an electric driving range of 19 miles.
