Maserati presents the MC20, an engineering and styling masterpiece that opens a new era for the Trident brand. With the MC20, Maserati returns to a stage where it has always starred, that of Supercars that combine luxury and performance with the unique Maserati Style. The MC20 is a Maserati with mind-blowing aerodynamic efficiency. Its superb looks conceal an uncompromisingly sporty soul, with the new 630 horsepower V6 Nettuno engine that delivers 0-100 km/h acceleration in under 2,9” and a top speed over 325 km an hour.
The MC20 is particularly light under 1.500 kg, and thanks to its power output of 630 hp it is best in class in weight/power ratio, at 2.33 kg/hp. This lightweight was achieved without sacrificing anything in terms of comfort. The MC20 has all the contents cars of this type must have today to satisfy a sporty yet sophisticated clientele, looking not only for performance but also for comfort and luxury. So a great deal of work was done on the materials. The entire chassis is in carbon fibre and composites, with the benefits of lighter weight, faster tool-go times and greater stylistic freedom in the design of forms. Carbon fibre enables the creation of shapes impossible with press-formed metal. The butterfly doors are a very obvious example.
Over two thousand man-hours in the Dallara Wind Tunnel and more than a thousand CFD (Computational Fluid Dynamics) simulations have enabled the creation of a car with refined aerodynamics which is also a genuine work of art.
Elegant and sporty, efficient and lightweight
Conceptually, the MC20’s aerodynamic design divides the car into two parts: an upper part where stylistic considerations predominate and a more technical lower part, colour-coded in black and carbon fibre respectively. In the car’s upper section, the forms respond primarily to aesthetic priorities and the aerodynamic features are amalgamated into the lines conceived by the designers, to achieve high efficiency without interfering with the sleek, elegant bodywork.
The air vents on the bonnet and those at the side that provides the engine’s air intake and cool the intercooler are thus “natural” features, virtually invisible when the car is viewed from some angles.
What’s more, there are no obvious aerodynamic appendages: just a discreet rear spoiler that enhances the up-washing generated by the floor and enhances the downforce with no detriment to the car’s great beauty.
In the lower part of the MC20, on the other hand, the technical component takes control.
The top speed is over 325 km/h with acceleration from 0 to 100 km/h in less than 2,9 seconds and from 0 to 200 km/h in less than 8.8 seconds.
A monocoque for three
The monocoque, in composite material, is a concentrate of technology and performance. The design of the carbon fibre monocoque has been achieved through the partnership between Maserati and Dallara, both leaders in the design and construction of racing sports cars.
The monocoque has been developed from the outset for all three types of car to be produced in the coming years: the coupé, the convertible and the future electric version. The monocoque’s architecture and geometry are the same for all three versions. Still,a they differ in the distribution of the carbon fibres and layers, to provide monocoques with different structural characteristics for the three different types of car: the focus for the coupé will be on lightweight and performance; the convertible demands greater torsional rigidity due to the absence of a roof; and the electric version will have more overall strength and enhanced protection for the battery area. Therefore, a single design embraces three versions, through changes only in the type, quantity and arrangement of the carbon fibres.
The very compact front suspension features a
double-wishbone with semi-virtual steering, two bottom links and one top link. The same semi-virtual layout is adopted on the rear suspension, one of the very few cases of this application on the market today.
The use of semi-virtual suspension allows the tyre’s contact patch to be kept constant while cornering, ensuring high lateral accelerations and keeping handling natural and instinctive in any situation and at any speed.
The 630 horsepower 90° V 6 cylinder 3,000 cc turbo engine, called the “Nettuno”, is new and protected by an international patent, because it transfers to a road car a technology previously only found in Formula 1. It is an engine 100% made in Modena, and currently the highest-powered 6-cylinder powerplant in production. Designed component by component by the engine specialists of the Maserati technical department with constant support from the Modena Innovation Lab, it has the most advanced technology of any road-car engine on today’s market.
There are three main components:
The pre-chamber: a combustion chamber placed between the central spark plug and the conventional combustion chamber, to which it is connected by a series of specially shaped holes.
The side spark plug: a standard spark plug that provides
back-up to ensure smooth engine combustion in operating conditions when the use of the pre-chamber is not necessary.
The dual (indirect and direct) injection system: combined with the fuel delivery pressure of 350 bar, it reduces noise at low rpm, cuts emissions and saves fuel.
The new Nettuno engine has a dual combustion chamber for each cylinder. A design which includes a prechamber, in which the main spark plug is installed. It also generates a power output of 210 horsepower/litre. This makes it currently the best-in-class 6 cylinder engine in terms of specific power output. – Press Release
