• Watch the 992 Porsche 911 Turbo S Take on the 991 Porsche 911 Turbo S

Can the 991 911 Turbo S beat its successor, or will the new model win the bragging rights?

Porsche replaced the 991 911 Turbo S with the 992 model and it came with quite a few changes on the outside, inside, and in the mechanical department. The 992 came with better specs on paper and was a step up over the 991. But, does it reflect the same on a drag strip? Well, Carwow decided to pit them both against each other to see who reigns supreme.

Does The 991 Hold The Candle Against the 992 911?

The Porsche 991 911 Turbo S came with a 3.8-liter, six-cylinder, twin-turbo engine that made 580 ponies and 553 pound-feet of torque. Power is sent to the wheels via a seven-speed dual-clutch automatic gearbox, which is arguably one of the best transmissions out there. It also features launch control and weighs around 3,530 pounds.

The Porsche 992 911 Turbo S features a 3.8-liter, flat-six twin-turbocharged engine that churns out 650 horses and 590 pound-feet of torque. Power is sent to all the wheels via an eight-speed dual-clutch automatic gearbox. It also features a launch control. The car weighs roughly around 100 pounds more than the previous 911. Porsche has mentioned that the new 911 is two-tenth of a second quicker to 60 mph from a standstill and 0.3 seconds quicker to a quarter-mile. Does that happen in this race too?

The Latest-Gen 911 Turbo S Is Definitely Faster

Spoiler Alert: The 992 911 Turbo S is the clear winner here. The old one is not a slouch by any means, but it shows how the current-gen model is a big improvement over its predecessor. There were three drag races here and the 992 won all of them rather comfortably. The latest car took 10.1 seconds to a quarter-mile whereas the 991 took 10.8 seconds! The difference here is more than Porsche’s take, but it could be the road conditions, tires, or the driver’s reaction time.

The rolling race from 50 mph, the 991 took off a lot quicker than its successor in the auto mode and only overtook it only after crossing 150 mph. But with gears in driver’s control, the new car beat the other one clearly.

What Are The Primary Differences Between The Two?

We’ve laid out the basic engine specs above, but here are some other facts. The gearing has been increased from seven to eight speeds and the gear shifts are now smaller. A larger central intercooler at the rear is 12-percent larger than the twin intercoolers of the previous model and this allows the engine to breathe better. Even the engine compression ratios have been increased from 10.1:1 to 10.5:1. The boost pressure, however, remains the same at 16 psi.

On the outside, the basic changes come in the form of a revised front fascia that now comes with rectangular air vents, sharper door handles, and a resculpted lower fascia. At the rear, you get a single-strip slim LED taillight. Also, the air vents are equipped vertically.

The cabin design and layout feel a little toned town as compared to the cockpit-like vibe of the 991. An 11-inch touchscreen system sits on the center console and replaces a lot of buttons seen previously.

The 992 Porsche 911 Turbo S is certainly superior to the 991 911 Turbo S and we witnessed the same in the numerous races seen here. But, when it comes to such cars, everyone has a different liking irrespective of which one is better than the other. What’s your pick here, though? Let us know in the comments section below.
