Porsche's 2025 911 GT3 reaches 60 mph half a second sooner with its dual-clutch than with its manual. The manual is still faster flat out.
The short answer
In a sprint, the dual-clutch wins: in every same-car pair below it reached 60 mph 0.2 to 0.6 seconds sooner. The manual wins back weight, sometimes money, and the fun of shifting.
How much quicker is a dual-clutch?
| Car (0 to 60 mph) | Source | Manual | Dual-clutch |
|---|---|---|---|
| 2025 Porsche 911 GT3 | Porsche | 3.7 s | 3.2 s |
| 2021 Porsche 718 Cayman GTS 4.0 | Porsche | 4.3 s | 3.8 s |
| 2015 BMW M4 | BMW | 4.1 s | 3.9 s |
| Porsche 718 Cayman GT4 (2020 manual, 2021 dual-clutch) | Car and Driver tests | 3.7 s | 3.3 s |
| 2022 VW Golf GTI | Edmunds test | 6.5 s | 5.9 s |
Quarter-mile times agree, manual first: 11.9 and 11.6 seconds for the GT4, 14.6 and 14.0 for the GTI.
Why is a dual-clutch faster?
One clutch runs the odd gears, the other the even ones, with the next gear preselected. A shift hands power from one shaft to the other. Volkswagen says each DSG shift takes under four-hundredths of a second.
Car and Driver launched its dual-clutch GT4 with launch control at 6,600 rpm.
Off the line, it can be a tie: Car and Driver's 2022 911 Carrera GTS hit 30 mph in 1.2 seconds with either gearbox. By 60, after one shift, the manual trailed by 0.4.
Where does the manual still win?
Weight. Porsche says the GT3's manual is 17 kg lighter.
Price. The dual-clutch cost $3,730 extra on the 2022 Cayman GTS 4.0 and $1,500 extra on the 2024 Hyundai Elantra N. The current GT3's manual is a no-cost option.
Feel. In early 2021, Porsche told Bloomberg about 70 % of US GT3 buyers picked the manual.
On the street
Porsche calls its dual-clutch PDK; Volkswagen says DSG. By Porsche's 2019 count, over three-quarters of its delivered 718s and 911s had PDK. Related: turbo vs supercharger and limited-slip differentials.
FAQ
Is a dual-clutch an automatic?
It shifts itself. BMW describes it as two gearboxes, each with its own clutch.
Is a dual-clutch worse in traffic?
Kia warns that repeated stop-and-go starts on steep hills can overheat its dry dual-clutch.
Is a manual ever faster?
At the top end, sometimes: Porsche claims 195 mph for the manual GT3 and 193 for the dual-clutch.
