[9] The car was developed by the Maserati Innovation Lab with an all-electric option slated to reach production in the future.

[12] The new car's logo appeared on a Maserati-sponsored Multi 70 trimaran's mainsail that was due to race in the RORC Caribbean 600.

[13] In late 2019, a series of spy shots were published online showing a highly modified Alfa Romeo 4C-based test mule of an upcoming new Maserati sports car.

The publication argued that the similarities that were identical to the aforementioned engines included the 90-degree V angle, the firing order of 1-6-3-4-2-5 (identical to the F154-based V6 engine found in the Alfa Romeo Giulia and Stelvio), arrangement of cooling passages, cylinders, and liners, oil filter mounting, bore and stroke, and rev limit of 8,000 rpm (the same as the Ferrari SF90 Stradale).

It features the same 3.0 litre twin-turbo V6 and styling but adds on the two-piece foldable hard-top that has an electrochromic glass roof.

Double wishbone suspension along with adjustable dampers, front and rear anti-roll bars provide ride height control for the car.

[26] The Nettuno engine has been fitted with two new turbochargers, increasing the power output to 544 kW (740 PS; 730 hp), sent to the rear 18 in forged aluminium wheels via a 6-speed sequential manual transmission paired with a mechanical limited slip differential.

[31] At the 2024 Monterey Car Week Maserati presented the GT2 Stradale, the GT2 version approved for road use but with extreme track performance.

The Maserati GT2 Stradale is powered by a 640 hp 3.0 twin-turbo Nettuno V6 with rear-wheel drive and a dual-clutch automatic transmission with 10 more horsepower and 60 kg less than the other MC20s.

While the engine and body shell remain the same as the road-going counterpart, the differences include an aerodynamic package consisting of a large rear wing, a new rear diffuser and a roof scoop, a stripped down interior having a single seat, fire extinguisher, adjustable steering wheel column and pedal box, a new 6.5-inch display and an FIA homologated roll-cage while retaining the air-conditioning, a six-speed sequential gearbox with a self-locking mechanical limited-slip differential, two-way adjustable dampers, a racing spec exhaust system and 18-inch forged alloy wheels.

Customers can also add the passenger seat, a rearview camera and a tire pressure monitoring system at an extra cost.
