Ferrari unveiled two new car models on September 18 2018. They are titled the Monza SP1 and Monza SP2.

Ferrari just unveiled sports cars that have no roof or windshields and run on the most powerful engine the company has built, according to the luxury car-maker. The Monza SP1 and SP2, the first models in a new concept of limited-edition series called Icona announced on Sept. 17, can go from zero to 60 miles per hour in 2.9 seconds and zero to 124 miles per hour in 7.9 seconds. They have a max speed of 186 miles per hour — a speed only experienced by Formula 1 drivers, according to Ferrari.

As many as 499 will be made and each will cost around $1.75 million each, according to Car and Driver. The Ferrari Monza SP1 is a single-seat road car, meaning the driver is the only passenger, while the Monza SP2 is a two-seater. Both cars have an 810 cv V12 engine and a sort of cockpit carved from the car's volume that wraps around the driver. They are constructed entirely out of carbon fiber, which makes the cars lightweight and the absence of a roof and windscreens helps with aerodynamics. Both cars are inspired by barchetta-body models (typically "open" two-seaters with no side window structures that are built for racing, according to RodAuthority.com) like Ferrari's iconic 1948 166 MM, the 750 Monza and the 860 Monza. These three cars helped Ferrari win five of the seven World Championship for Sports Cars series in the 1950s.

Managing the aerodynamic air flow inside the cockpit in the absence of a windscreen was a challenge for Ferrari, so it developed patented technology called the "Virtual Wind Shield" that allows air to shoot up just in front of the driver behind the steering wheel. (The purpose is to deviate part of the air flow to maintain driving comfort.)
