Porsche 911 GTS beats AMG GT63 and BMW M8 in ultimate coupe test

Porsche 911 GTS proves its edge over AMG GT63 and BMW M8 in speed, handling, and daily usability. Explore the full breakdown of this thrilling comparison.

When the question is speed, emotion, and daily usability — three contenders step onto the stage: the Porsche 911 GTS, Mercedes-AMG GT63, and BMW M8 Competition. Each has its own formula for success, but only one can claim the crown.

Performance Engineering Unleashed

The Porsche 911 GTS arrives equipped with a cutting-edge hybrid system powered by a Rimac-sourced battery. A turbocharged 3.6-liter flat-six, paired with electric assistance, rockets the car from 0 to 60 mph in just 2.82 seconds and down the quarter-mile in 10.79. The AMG GT63 relies on its tried-and-true 4.0L V8 and all-wheel drive, delivering 585 hp with thunderous authority. Meanwhile, the BMW M8 packs 625 hp from its 4.4L twin-turbo V8 — fast, no doubt (3.25s to 60 mph), but not quite enough to catch the Porsche.

The Sound of Power

If it’s all about exhaust notes, the AMG wins — hands down. It’s visceral, aggressive, and addictive. Porsche’s tone is more subdued, almost clinical. BMW’s exhaust sits somewhere in between — competent but not stirring.

Design: From Bold to Reserved

Visually, the AMG GT63 takes the lead with its muscular shape and sweeping lines. Porsche maintains its elegant silhouette, though the new front-end design polarizes. The BMW M8 looks sharp from the side and rear, but its front fails to excite.

Cabin Quality and Tech

Porsche once again takes the lead with an intuitive, clean, and quality cabin. The infotainment is well-integrated and the digital cluster is class-leading. AMG’s cabin looks stylish and modern but suffers from some cheap-feeling plastics. BMW offers space and traditional BMW build quality, but the outdated infotainment and layout hold it back.

Practicality, Considered

Surprisingly, the BMW proves the most practical, boasting a 420L boot and the most comfortable rear seats. Porsche offers a 135L front boot, while the AMG sits in between with 320L and hands-free access. All cars allow seat folding for extended cargo options.

On the Road: Confidence vs Comfort

The Porsche is the benchmark for driver engagement. Even with the added hybrid weight (around 150 kg), its sharp steering, confidence-inspiring brakes, and sublime balance remain intact. AMG’s GT63 surprises with its ease of control despite its size — a real point-to-point weapon. The BMW, while competent, feels more like a luxury GT than a focused sports machine. It’s smooth, comfortable, but lacks the thrill of its rivals.

Final Verdict: Head Meets Heart

The BMW M8 is the smart, comfortable choice for those who value space and refinement. The AMG GT63 blends drama with everyday usability, making it a compelling all-rounder. But it’s the Porsche 911 GTS that shines the brightest — thrilling, advanced, and reassuringly complete. It’s the sports car that captures both the heart and the mind. That’s why it wins this test.
