How much does the roof down affect the speed of the car?

How much does the roof down affect the speed of the car? Paul Maric from the YouTube channel CarExpert tried to answer the question. He lined up two Porsche models, the 911 Turbo Coupe and the 911 Turbo Cabriolet.

Both models are powered by a 3.8-liter twin-turbo flat-six engine with 572 hp (421 kW) and 553 lb-ft (750 Nm) of torque. They are equipped with an eight-speed double clutch automatic gearbox that transmits power to all wheels.

The first test was at the 1/4 mile where the 911 Turbo Coupe achieved a time of 11.4 seconds at 206.3 km / h and reached 62 mph in 3.7 seconds. The 911 Turbo Cabriolet (Roof Up) achieved a time of 11.5 seconds at 207.5 km / h and reached 62 mph in 3.7 seconds.

Test 2 (Roof Down) – At 1/4 mile both models had the same time of 11.1 seconds. The 911 Turbo Coupe reached 62 mph in 3.3 seconds, while the 911 Turbo Cabriolet reached 62 mph in 3.2 seconds.

Test 3 (Roof On) – They equalized the weight of both cars, since the Babriolet is 20 kg heavier than the Coupe. This time, at 1/4 mile the Coupe achieved a time of 10.9 seconds and reached 62 mph in 3.1 seconds. The 911 Turbo Cabriolet achieved a time of 10.8 seconds and reached 62 mph in 3.0 seconds.

Test 4 (Roof Off) – 911 Turbo Coupe achieved a time of 11.0 seconds at 206.6 km / h and reached 62 mph in 3.1 seconds. The 911 Turbo Cabriolet achieved a time of 10.8 seconds at 208.2 km / h and reached 62 mph in 2.9 seconds.

Test 5 – They swap lanes and this time the Coupe was faster with 10.8 seconds, while the Cabriolet achieved a time of 11.1 seconds.

How relevant this was, we’re not sure. Maybe some other tests would show more accurate results. One thing is for sure, it was interesting to watch.

2022 Porsche 911 Sport Classic

According to some rumors, the Porsche 911 Sport Classic will debut early next year in a limited edition. Like the previous model which was made in 250 units and sold before the official presentation, the same is expected from the new 911 Sport Classic.

The arrival of the new 911 Sport Classic is confirmed by spy photos in which the car is shown with a bit of camouflage on it, which means that the tests are coming to an end. As we can see it shares the design with the 911 Turbo model but with some minor modifications, such as the rear spoiler with brake light and front grille.

The Porsche 911 Sport Classic will be powered by a 3.0-liter twin-turbo direct-injected flat-six engine with 473 hp (352 kW) at 6500 rpm and 420 lb-ft (569 Nm) of torque at 2300 rpm. The same engine uses the Porsche 911 GTS. Reaches 62 mph in just 3.3 seconds with a top speed of 193 mph (310 km / h). Power is transmitted to the rear wheels via a 7-speed manual or 8-speed twin-clutch automatic transmission. It is mounted on slightly larger wheels with five-spoke aluminum rims.
