The Maserati GranCabrio and the Mercedes-AMG SL are two of the most sought-after roadsters among enthusiasts. Two great roadsters that rely heavily on power, but whose real strength lies in their driving experience and the elegance of their shapes and interiors.

We try to compare them, analysing all the details that make them so special.

The exterior

Maserati and Mercedes leave no one indifferent. The softer lines of the GranCabrio and the more angular lines of the AMG SL both captivate at first glance. A combination of beauty and aggression, with polished surfaces that give way to an imposing radiator grille on both models.

The wheels are 21 inches for both convertibles, while the wheel arches feature the three slots characteristic of the Maserati and a thin insert on the Mercedes (the name of the version is present on both). There's plenty of aggression at the rear too, with four trapezoidal tailpipes on the SL and round ones on the GranCabrio.

The interior

Both roadsters boast refined interiors, with great attention to detail in terms of both upholstery and technology. In the Maserati, the electric soft-top controls can be operated at speeds of up to 30 mph, with the roof opening in 14 seconds and closing in 16 seconds.

The seats are in leather with elaborate backrest textures, while the dashboard is dominated by soft-touch materials. Digital instrumentation is represented by the 12.3-inch panel with configurable graphics, the 12.3-inch infotainment screen (with Maserati Intelligent Assistant voice assistant and wireless connectivity for Apple CarPlay and Android Auto) and the 8.8-inch screen for managing climate control.

The GranCabrio is also equipped with a neck heating system that blows warm air through the back of the front seats and is adjustable to three speeds. In addition, a windscreen can be fitted in front of the rear seats to reduce turbulence in the cabin when the roof is lowered.

Refinement and luxury also characterise the interior of the Mercedes-AMG SL. The German supercar's upholstery and interior design are equally meticulous, with carbon and metal mouldings alternating with leather elements. The Mercedes is equipped with a rectangular instrument cluster and an 11.6-inch infotainment screen.

The latter can be tilted from 12° to 32° to avoid glare, and can be used to control all aspects of the car, from climate control and driving modes to Apple CarPlay and Android Auto wireless connectivity. In the case of the Mercedes, the soft top can be operated at speeds of up to 37 mph and opens and closes in 15 seconds.

The front seats are sporty, with integrated headrests and an Airscarf to warm the back of the neck.

The Maserati GranCabrio is available with the 3.0-litre V6 Biturbo Nettuno producing 550 PS and 650 Nm. Combined with all-wheel drive and an 8-speed automatic gearbox, this six-cylinder engine propels the Maserati from 0 to 62 mph in 3.6 seconds and to a top speed of 196 mph. Four driving modes are available (Comfort, GT, Sport and Corsa), as is the ESC OFF function, which deactivates all electronic controls.

The Maserati GranCabrio Folgore made its debut later, a 100% electric version powered by three motors, one at the front and two at the rear, for a total installed power of over 1,200 PS. It has a 92.5 kWh battery and a claimed range of over 249 miles, calculated according to the WLTP cycle.
