Maserati has chosen to collaborate with Bosch in the creation of the new Ghibli Hybrid; this is the first hybrid sports car produced by Maserati, and will be equipped with a 48V Mild Hybrid system made with the components and technologies supplied by Bosch. The installed battery is small, just 10cm thick and 13 kW of total power.
The system designed by Maserati includes a 48V lithium ion battery, a DC / DC converter and an electronic control unit ECU . All this will be combined with a 4-cylinder in-line engine of just under 2000cc, a seemingly strange choice but which is very easily explained: firstly, a smaller engine guarantees reduced consumption and emissions - while the performance gap is covered by the electric motor, so as to rightly maintain the sporting soul - and secondly it is a bureaucratic choice. In fact, China is a very important market for Maserati, and in China at the moment there are various concessions on the purchase of cars with 4-cylinder engines, so the engine chosen was designed to be easily sold in China as well.
On the emissions side, the small 4-cylinder engine with 48V hybrid system emits 25% less CO2 than the 350 horsepower V6 petrol engine, while maintaining a respectable performance of 330 horsepower.
The components dedicated to the hybrid system weigh about 15 kg, but the reduction in size of the engine, which went from 6 to 4 cylinders, allows for a total weight of 80 kg less than the Ghibli with a classic thermal engine.
Thanks to the technologies provided by Bosch, the new Maserati Ghibli Hybrid will also be able to offer a level 2 autonomous driving system, called Active Driving Assist.
