Marelli has announced that it will be supplying the three motor setup with installed power of 1,200 HP for the Maserati GranTurismo Folgore.
The company said that the e-motor solution has been fully developed and produced in-house by Marelli at its Modugno plant (Bari, Italy). Both the product and the related specific and extremely efficient manufacturing process have been developed in a two-year span, a record time to market.
The e-Powertrain system of the Maserati GranTurismo Folgore is based on state-of-the-art 800V Marelli’s electric motors, one placed in the front and two in the rear e-axle, resulting from the company’s extensive know-how in motorsport electrification and flow-down to series production applications.
The high levels of power density of (9.2 kW/kg) and the total torque of 1,350 Nm, ensure performance as well as driving comfort, with one of the best weight/power ratios on the market, the company said.
On the production side, leveraging on the internal engineering and manufacturing capabilities, latest generation processes have been applied, starting from the rotor production, in which a cryogenic cooling process, reaching a temperature of about -200°, ensures the shaft perfectly fits into the stack.
Also the stator manufacturing process is unique, due to the hairpin’s two-steps forming, one for the 2D and the second for the 3D forming. To grant product quality, an end-of-line station tests every single e-motor before it is delivered to the customer, assessing its electrical characteristics as well as its mechanical and NVH (Noise, Vibration and Harshness) performance.
This adds to the over 70 quality check that are performed during the whole production process on the most important characteristics, 41 of which are fully automated, the press release from Marelli said.
In addition to the electric motors, Marelli has also contributed to the exclusive lighting signature of the new Maserati Gran Turismo with full LED headlamps, that on specific trims also feature Adaptive Driving Beam Matrix system, while on the connectivity side, the vehicle is equipped with Marelli’s Telematic Control Unit.
Hannes Prenn, President- Electric Powertrain division, Marelli, said, “Our long-standing technical know-how in electric motors, combined with continued focus on innovation and established manufacturing capabilities were all key factors in allowing us to develop the best solution to grant the extraordinary performance of this unique car.”
