Maserati GranTurismo Folgore
The fratelli Maserati got their automotive start building 2.0-liter grand prix racers for Diatto while overseeing their own spark-plug-manufacturing business. In 1926, when Diatto suspended racing operations, the brothers started building highly successful Maserati race cars. To improve profits and ensure funding for their racing efforts, the brothers set about adapting their winning 1.5-liter racing engine and chassis for road use in 1941, with the resulting A6 1500 Gran Turismo appearing in 1947. Today, circumstances are again forcing Maserati down a new path—this time toward electrification—and the brand will again incorporate motorsports tech on its first production EV. Fittingly, it will again be a grand tourer. But rather than adapting a race car for road use, this time Maserati co-developed an all-new Formula E race car alongside the 2024 GranTurismo Folgore.
The racer will run in the ninth e-Prix season in early 2023. The road car arrives later in the year, and we just got an exclusive opportunity to test it out on Maserati's home track—Autodromo di Modena.
The heart of any racing or performance car is its powertrain, and just as motorsports has always done for combustion engines, Formula E racing development is unlocking new ways to maximize power and minimize energy use. The solutions aren't always cheap, but big racing budgets and luxury grand-tourer sticker prices can help incubate innovation. The 2024 Maserati GranTurismo Folgore employs three motors, designed and built by Maserati. Each arrays 100 permanent magnets in intricate vee formations within the rotors. Note: These are traditional barrel-shaped radial-flux motors, not the pancake-style axial-flux type; none can be declutched, so they're always powered, and all those magnets make these motors too pricey for mainstream Maserati EVs like the forthcoming Grecale Folgore SUV.
To achieve the same low seating position and leg environment found in the Nettuno V-6-powered GranTurismo (which changes little relative to the previous model), the battery pack fills the center tunnel, expanding into the engine compartment in front and the area beneath the rear seats in back. Pouch-style batteries comprise 32 modules to form the pack, which is built at Maserati's Mirafiori factory near Turin. Total capacity is 92.5 kWh, 88.0 of which are usable. The 800-volt pack can be DC fast-charged at 270 kW, taking the battery from 20 to 80 percent in 18 minutes. Level 2 AC charging can be as fast as 22 kW with a 100-amp L2 charger, and an upgrade to 300- or 350-kW fast-charging is anticipated.
Each motor gets its own power inverter (to convert DC battery power to AC motor power or vice versa), and Maserati says it will be first to production with these more efficient, costlier Formula E-derived silicon-carbide MOSFET inverters. They play a key role in delivering both the GranTurismo's power and its comparative efficiency.
All those permanent magnets can handle a lot of electromagnetism to deliver stout torque over a wide rpm range. Each motor can deliver 402 hp and 332 lb-ft of torque to the road. But the battery can only deliver 751 hp total, and then only for 30 seconds of continuous full power. (Note that the system can recover a total of 818-hp worth of regen braking.) And although the EPA has yet to get its hands on a 2024 Maserati GranTurismo Folgore for testing, the manufacturer expects a 250-mile rating—impressive given the car's size, long-legged gearing, and lack of a disconnect mechanism for highway cruising (which aren't a thing in racing).
