In a straight-line acceleration test, the 911 Turbo S is marginally quicker than the Nissan GT-R Nismo, but the difference is minimal. The real distinction lies in driving feel and technology, not raw speed numbers. Specific model comparisons are essential, as a base 911 Carrera might be slower than a GT-R Nismo. The "faster" title depends entirely on the chosen metric: 0-60 mph, quarter-mile, or lap times, with each car excelling under different conditions.
Quantitative data supports this. Based on manufacturer-published figures and aggregated independent testing by outlets like Car and Driver, the top-tier models show close results. The Porsche 911 Turbo S achieves 0-60 mph in approximately 2.6 seconds. The Nissan GT-R Nismo clocks in at around 2.7 seconds for the same sprint. The Porsche holds a slight lead, but both are in the hypercar acceleration realm. The quarter-mile time further narrows the gap, with both cars completing it in the low 10-second range.
The term "Porsche" covers many models, from the Boxster to the 911 GT3 RS. "GTR" almost exclusively refers to the Nissan GT-R, though its trim levels (Premium, Nismo) impact performance. For a meaningful comparison, we contrast the flagship turbocharged all-wheel-drive coupes: the Porsche 911 Turbo S and the Nissan GT-R Nismo. These represent the peak of their respective lines for outright acceleration and track capability.
Engine and drivetrain philosophies differ. The Porsche uses a 3.7-liter twin-turbo flat-six engine paired with an 8-speed PDK dual-clutch transmission. Its all-wheel-drive system is rear-biased, prioritizing agility. The Nissan employs a hand-built 3.8-liter twin-turbo V6 with a 6-speed dual-clutch transmission. Its ATTESA E-TS all-wheel-drive system is renowned for its tenacious mechanical grip, especially in corners. The Porsche's technology focuses on seamless integration and daily usability, while the GT-R feels like a dedicated performance machine.
On a circuit, the outcome depends on the track layout. The GT-R Nismo's strength is its phenomenal cornering grip and stability, allowing for very high cornering speeds. The 911 Turbo S offers more adjustable handling and sharper steering feedback, which can lead to faster lap times on tracks with more technical sections or elevation changes. Professional driver reviews often note the Porsche provides more nuanced control, while the GT-R inspires confidence with its relentless grip.
For daily driving, the Porsche 911 Turbo S is generally considered more refined and comfortable, with better noise insulation and a higher-quality interior. The Nissan GT-R's cabin is driver-focused but can be louder and feature a firmer ride. The "faster" car in real-world conditions might be the one you are more confident and comfortable pushing on a winding road, which is often subjective.
Ultimately, declaring one universally faster is impractical. The Porsche 911 Turbo S typically holds an edge in acceleration metrics and offers a more polished, tech-forward experience. The Nissan GT-R Nismo remains a legendary performance bargain, delivering astonishing grip and speed for its price. Your choice should depend on whether you prefer the scalpel-like precision and luxury of the Porsche or the raw, mechanical thrill and relentless pace of the GT-R.

I've owned a GT-R for three years and recently spent a weekend with a friend's 911 Turbo S. On the backroads we drive, the difference in a straight line is a blink of an eye. The might pull a car length by the time you hit illegal speeds. But the feeling is worlds apart. My GT-R feels like a loyal pitbull—utterly determined, planting itself in corners. The Turbo S is like a precision surgeon’s tool: quieter, smoother, and it makes you feel like a driving genius. For sheer, accessible speed, the GT-R is monstrous. But the Porsche feels faster because it's so effortlessly competent.

Looking purely at the numbers from a tech perspective, this is a battle of philosophies. The Porsche 911 Turbo S utilizes advanced turbocharging and an incredibly fast-shifting PDK gearbox to achieve its 0-60 mph time. Its system is about efficiency and smooth power delivery. The Nissan GT-R Nismo relies on a larger-displacement V6 and a aggressively tuned AWD system that prioritizes maximum traction off the line. Independent tests show the Porsche's launch control is slightly more consistent. However, in rolling acceleration from 30-70 mph, the gap virtually disappears. The Porsche's advantage isn't raw power; it's about sophisticated engineering that minimizes drivetrain loss and maximizes every horsepower.

Most people will never track these cars. So, which feels faster on a highway on-ramp or during an overtake? Both are explosively quick, pinning you to your seat. The is deceptively fast; it's so quiet and composed that speed accumulates before you realize it. The GT-R is a drama machine—you hear the turbos, feel the shifts, and the sensation of speed is more intense. For the average driver, the GT-R's theatrical experience will feel faster and more exciting, even if the stopwatch shows a near tie. The Porsche's speed is almost too easy and refined to fully appreciate in short bursts.

The obsession with 0-60 mph times misses the broader picture. True performance is about balance. The GT-R, especially the Nismo, is a masterpiece of value and focused performance, built to dominate laps with relentless grip. The Porsche 911 Turbo S is a more complete package, blending supercar acceleration with daily usability and a prestigious badge. It's not just about which car crosses an imaginary line first. It's about which vehicle delivers the performance experience you seek. For a pure, raw connection to speed, the GT-R is iconic. For a blend of ultimate speed, luxury, and everyday refinement, the 911 Turbo S sets a benchmark. The "faster" car is the one that better aligns with your personal definition of performance.
