Maserati switching to in-house twin-turbo V6 and turbo four

Automotive News has been able to put some output figures to the two primary engines that will power Maserati's renaissance. Last year the Italian luxury brand sent notice that it would terminate its deal to with Ferrari to use the Maranello-sourced F160 3.0-liter twin-turbo V6 and F154 3.8-liter twin-turbo V8. As new Maserati models appear and current models are overhauled, the brand will begin installing either Maserati's own 3.0-liter twin-turbo V6, or an FCA-sourced 2.0-liter turbocharged four-cylinder. The V6 will greet the world from the middle of the MC20 supercar poised for debut in September, assuming nothing goes worse with the world than it already has. Rumor from Mopar Insiders and Allpar forums is that Maserati began building its V6 based on Alfa Romeo's 690T V6. Alfa Romeo puts the 690T in the Stelvio and Giulia Quadrifoglio, the engine's development having started seven years ago with Ferrari's F154 V8 as its heart. Tuned for speed, peak output could reach 542 horsepower. After making its home in the racy coupe, the V6 will also serve a new midsize Maserati crossover coming next year, as well as the next GranTurismo coupe and GranCabrio convertible. In the crossover, power is apparently limited to no more than 523 horses. In Maserati's new V6, one piece of technology that permits such high output and emissions friendliness is turbulent jet ignition (TJI). German supplier Mahle has been developing the technology for at least 10 years, and put it to use in Ferrari's Formula 1 engine about five years ago, after which Japan's Super GT manufacturers picked it up. Instead of a spark plug igniting fuel directly in the combustion chamber, TJI places the spark plug and an injector nozzle at the top of a "jet ignition pre-chamber assembly." The injector shoots a mist of gasoline into the pre-chamber, the spark plug fires, and the force of ignition in the pre-chamber sprays the combustion through tiny holes at the bottom of the pre-chamber into the cylinder as the piston rises. Mahle says the shorter burn and improved combustion spread means cleaner-burning gas engines that emit fewer emissions.   AN says that the "new V-6 engine will be 'electrified' in some form." It's not clear if that means all versions of the V6 will get some sort of hybrid assistance, or if — as had been thought — there will be a non-hybrid unit.

Watch the Maserati MC20 unveiling

UPDATE: You can now read all the details and see photos of the MC20 here. Maserati has been teasing its upcoming MC20 mid-engined coupe since spring, and today we finally get to see it in the flesh. Maserati will begin the livestream at 2:35 PM Eastern, and you can watch along with us in the video above. If you need a reminder of what we're looking forward to, we're expecting a two-door performance car with a twin-turbo 3.0-liter V6 mounted amidships providing about 630 horsepower and 538 pound-feet of torque. Notably, that motor comes from Maserati itself, rather than sourcing it from Ferrari. In addition to the original teasers from March and a more recent studio teaser from September 1, we've also seen some spy photos of the MC20 out in the wild. There was also a MC20 tribute to Stirling Moss, as well as a 1940 Targa Florio tribute. Check those out to get up to speed, and watch the live event with us here shortly.

Maserati MC20 GT2 returns the Trident to GT racing in 2023

Seems we got ahead of Maserati, but now we're on the same page with the Italian carmaker. We wrote about the Maserati Project24 earlier this week, a limited-edition track car not built to race a specific series, instead chasing Maserati's own performance targets. We wondered whether the Project24 was a pivot from the rumored GT3 program planned for the MC20 years ago. Turns out the Project24 is an offshoot of the GT2 program for the MC20, the Italians in Modena announcing they've developed an MC20 GT2 to compete in the Fanatec GT2 European Series Championship next year. The base tech specs listed so far for the MC20 GT2 are the same as the Project24. The twin-turbo Nettuno V6 shifts through a six-speed sequential auto with paddle shifters, sending power to the rear wheels through a mechanical limited slip differential. Brembo CCMR racing brakes hang off a double wishbone suspension with anti-roll bars front and rear and adjustable dampers, just behind custom, forged 18-spoke center lock wheels on racing slicks that can be changed easily thanks to on-board air jacks. A single seat in the cabin is accessorized with an adjustable, multifunction carbon fiber steering wheel, an adjustable pedal box, and air conditioning. Safety features include an FIA fuel tank, rain light, roll cage, six-point harness, and fire extinguisher.  The differences that we know of include output, curb weight, and the aero package. Series organizer SRO says GT2 is "formulated to bring gentlemen drivers back to the front of the stage ... whilst being fast and spectacular enough to secure the values of SRO-promoted championships, should the current GT3 category become too expensive for too many of our teams and drivers." GT2 regulations cap output at around 630 hp, just nine more than the standard MC20 throws down — and 110 hp less than the Project24. The series' Balance of Performance rules will ultimately determine race weight and output. The regulations also draw limits around aero devices that Maserati Stile didn't need to heed on the Project24. The aero bit is especially important here because GT2 cars are more powerful than GT3 entries but designed to be less reliant on aerodynamics than GT3 cars, making GT2 versions easier for amateurs to drive at the limit.  This is Maserati's first dip back into GT racing above the GT4 class since the MC12 GT1 that snagged close to 100 wins between 2004 and 2010. The race division will sell cars to individuals and race teams.
