The new Portofino M, which stands for Modificata, is an improvement upon an already stunning Ferrari, but it’s natural to compare it to its contemporaries rather than its forebears. If you find yourself thinking about the merits of the Ferrari Portofino M vs. Mercedes-Benz AMG GT, you’re certainly not alone — fortunately, it quickly becomes clear that one of these supercars is in a class above the other.

Portofino M and AMG GT Roadster: Performance and Powertrain

A quick look at the raw numbers confirms what most auto enthusiasts might assume: the Ferrari offers vastly superior performance to the Mercedes-Benz. This is clear once you get behind the wheel of either, of course, but even a cursory glance at the specs of each vehicle makes it apparent.

In terms of raw power, the Portofino M 3.9L V8 Twin-Turbo engine produces 612 hp and 561 lb-ft of torque. The GT Roadster’s 4.0L V8 gives you less power despite its greater displacement, offering only 523 hp and 494 lb-ft of torque. This power disparity has real-world consequences, too: while the Ferrari Portofino M can jump from a standstill to 60 mph in 3.45 seconds and reach a top speed of 200 mph, the Mercedes AMG GT Roadster takes 3.7 seconds to reach 60 mph and can only manage a top speed of 193 mph. It may not sound like a big difference, but it feels like an eternity on the track.

Exterior Design

What makes a Ferrari a Ferrari is about more than what’s under the hood: it’s the thoughtful, elegant design that’s gone into the vehicle’s svelte body to maximize its aerodynamic efficiency and make it the envy of the road from Indianapolis to Milwaukee.

There is a harmony and a balance to the design of the Portofino M that the AMG GT Roadster doesn’t offer. The Mercedes-Benz has a brutishly large front end, giving the vehicle an unbalanced appearance — a stark contrast to the Portofino. But the Ferrari’s advantage here is about more than just aesthetics: it’s a masterwork of aerodynamic engineering. The M’s tail is more compact than the standard Portofino’s due to a new exhaust system that’s allowed for the removal of the silencer assembly, for instance; the new rear diffuser is now completely separate from the bumper, allowing it to be made of carbon fiber; and the front bumper also incorporates new air intakes.
