Maserati MC20 Cielo
In 2022, the trident-branded marque unveiled the MC20 Cielo, a drop-top variant of the MC20 halo sports car. 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. The roof system weighs an additional 65 kg, and the folding & unfolding of the roof sequence takes only 12 second.
In 2020, Maserati announced a six-cylinder engine for the MC20. The engine was described as a 90-degree, 2,992 cc (3.0 L; 182.6 cu in) V6 with a dry sump, twin-spark and pre-chamber ignition system. It also has dual turbochargers and fuel injectors. The 220 kg (485 lb) Nettuno engine can produce 630 PS (463 kW; 621 hp) at 7,500 rpm and 730 N⋅m (538 lbf⋅ft) of torque from 3,000 to 5,500 rpm. It redlines at 8,000 rpm.
The Nettuno engine's use of a passive pre-chamber is a unique quirk. Inspired by Formula 1 and combined with the use of twin-spark ignition, one inside the small cylindrical pre-chamber, placed at the center of combustion chamber, and another placed in the traditional combustion chamber, designed to help combustion in low-load scenarios.
