Maserati teases MC20 prototype again reminiscing about the Targa Florio

Maserati spent its weekend reminiscing about victory in the 1940 Targa Florio, putting an MC20 prototype to work enhancing the gravitas of the anniversary. After winning the Targa in 1937, 1938, and 1939 with the Maserati 6CM and its 1.5-liter supercharged inline-six throwing 175 horsepower, the House of the Trident showed up in 1940 with the brand new 4CL powered by a 1.5-liter turbocharged four-cylinder cranking 220 hp. Luigi Villoresi, who'd driven the 6CM to triumph the year before, crossed the line first in the 4CL to close out European racing until the end of World War II. With a return to racing on the automaker's mind, Maserati took a camouflaged MC20 to the same Favorita Park roads that hosted the Targa. The soft-focus spy shots were taken in front of the Floriopoli stands, a stretch of bunting and banners not far from the Targa start line as historic competitors headed into the Sicilian mainland. The MC20 is as photogenic in these shots as all the others, and as mysterious. The automaker seems intent on making everyone wait until the September debut to for any details that the prototype doesn't put on display. Prime among enthusiast interest is the powerplant. With Ferrari shutting down its supply of engines to the fellow Modenese sports car maker, Maserati says its new mid-engined coupe will be "the first car to use [its] new engine, brimming with innovative technological contents, developed and built by Maserati in-house." Short odds figure on a molto potente twin-turbo V6 sending power to the rear wheels through an eight-speed dual-clutch transmission, the long money isn't afraid to bet on a 4.0-liter twin-turbo V8  to replace the F154 V8 that Ferrari provides. With race engineers undoubtedly sorting out a version for sports car racing as we speak, Maserati will certainly hope the competitive version matches the exploits of the 4CL. The vintage race car took pole in its first race, earned its first victory two races later, snatched up a bag of silverware before WWII, won the first race held in Europe after the war ended, and continued winning in 4CL and 4CLT trim until 1951 to take 31 total victories — nine more than the MC12 race car.

Ferrari to stop supplying Maserati with its engines

The Ferrari Q1 earnings call was full of information, and perhaps the biggest revelation was that Ferrari is going to stop supplying engines to Maserati. CEO Louis Camilleri broke the news, and The Motley Fool posted a transcript of the whole call online. "Eventually, we will no longer supply engines to Maserati, which actually from our perspective is actually a good thing, both from a margin perspective, but also the fact that we can transfer a lot of the labor that's been focused on the engines to the car side of the business," Camilleri says. Maserati has used Ferrari engines (arguably, one of the most compelling reasons to buy a Maserati) in its vehicles since 2002, a little while after Fiat passed Maserati off to the prancing horse. The partnership continued as both Ferrari and Maserati were under the same house at FCA. Then when Ferrari was spun off from FCA in 2015, they kept the supply steady to Maserati. Those engines include a 3.8-liter twin-turbo V8, 3.0-liter twin-turbo V6 and a 4.7-liter naturally aspirated V8. Camilleri said Ferrari will officially stop in 2021 or 2022, with no intention of supplying anybody with engines beyond that. Of course, this leaves Maserati high and dry with no engines for its growing lineup. Maserati will have to reach into the FCA parts bin, find a new outside supplier or develop its own engines. Battery electric sounds out of the question. As of now, there doesn't appear to be a clear plan going forward. We've reached out to Maserati to see if they have any comment on the situation as it stands.

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.
