Maserati details the new, 630-hp V6 that will power its mid-engined MC20 coupe

Maserati is done leaning on former sister company Ferrari for technical support. It has unveiled the six-cylinder engine it designed and will build in-house to power the MC20 supercar that's scheduled to make its debut later in 2020. Ferrari's willingness to develop and/or build engines for Maserati shrank significantly when it split from former parent company Fiat-Chrysler Automobiles (FCA) in early 2016 and became independent. Insiders knew the division would be spun off, so they began designing Maserati's new engine (which is called Nettuno) in 2015 and accelerated the process in 2017. It's a 90-degree, 3.0-liter V6 with a dry sump and a twin-spark, pre-chamber ignition system rooted in racing. In this application, it's twin-turbocharged (the turbos are mounted on the outside of the engine rather than in the middle of it) and it's equipped with both direct and indirect fuel injection.  All told, the 485-pound Nettuno engine develops 630 horsepower at 7,500 rpm and 538 pound-feet of torque between 3,000 and 5,500 rpm. It continues revving to a redline of 8,000 rpm.  Matteo Valentini, Maserati's chief engineer, explained the Nettuno engine will ultimately power the company's entire range of vehicles, though he stopped short of naming the specific models that will use it after the MC20. He added the six-cylinder will "bring Maserati back into the world of racing," meaning its output will likely grow in the not-too-distant future. We'll learn more about the engine when the MC20 makes its debut September 9. What remains to be seen is whether Maserati will replace the V8 available in the Levante and the Quattroporte, or if it will surf the downsizing wave sweeping across the industry. Developed jointly with Ferrari in the early 2010s, that engine makes 590 horsepower when it's bolted in the Levante Trofeo's bay, meaning its output is eclipsed by the Nettuno V6's. Both engines are built around a 90-degree architecture, so the 3.0-liter V6 could turn into a 4.0-liter V8 if it's modular enough to gain a pair of cylinders — and if Maserati sees a market for another eight-cylinder.

Maserati Project24 is a custom, limited-edition, track-day special

Maserati joins the parade of limited-run, track-only cars designed to a set of specs instead of a set of established racing regulations. The entry is known by the codename Project24 at the moment, and Maserati says it will build just 62 examples. We don't know the significance of 24 nor of the production run. When the automaker launched the MC20, it said it planned to get return to heritage values founded at Formula 1 and sports car tracks around the world. While we wait on an MC20 developed for FIA GT racing, Project24 will be automaker's second outlet for racing aspirations, the Italians planning on entering Formula E next season. It's possible the Project24 is an offshoot of Maserati's reportedly dead GT3 program for the MC20. In December 2020, Daily Sports Car reported that a GT3 challenger "was said to be under development" when Maserati debuted the MC20, but perhaps due to ramifications of Covid, the circuit version was "shelved for the time being." The automaker hasn't divulged performance targets for the Project24, only a weight target: Below 1,250 kilograms, or 2,756 pounds. If achieved, the racer would be 552 pounds less than Maserati's claimed weight for the MC20. Part of the weight loss comes courtesy of carbon fiber bodywork that's two inches wider than on the MC20, Lexan windows, and making the passenger's seat optional. The gains should be felt everywhere around a track, especially because Project24's 3.0-liter V6 engine sports a larger pair of turbos that boost output by 119 horsepower, to 740 hp. The road car's eight-speed automatic is replaced by a six-speed sequential auto with paddle shifters, from there sending power to the rear wheels through a mechanical limited slip differential instead of the electric LSD in the MC20. 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. An adjustable front splitter and rear wing fine tune aero performance, on-board air jacks help pit crews put in the best performance.   The cabin offers an adjustable, multifunction carbon fiber steering wheel and pedal box. The wheel contains a digital display working alongside a dash and data acquisition system, but a driving performance optimization display is extra.

Maserati Grecale and Alfa Romeo Tonale delayed

MILAN — Maserati on Monday delayed the launch of its new Grecale SUV until the spring of 2022 from November this year due to a global chip shortage. The announcement by the luxury brand, part of Stellantis, comes as a shortage of semiconductors forces automakers around the world to slow or suspend production. Maserati said its decision stemmed from ongoing disruptions in the supply of parts. "In particular, due to a scarcity of semiconductors, production volumes would not adequately meet expected global demand," Maserati said in a statement. A global premiere for the Grecale, which will be produced in Cassino in central Italy, was initially scheduled for Nov. 16. Stellantis this month also confirmed it would present the Tonale, the new Alfa Romeo SUV, next March after it had been expected at the end of this year. Stellantis, formed this year though the merger of Fiat Chrysler and France's PSA, has halted production at several plants, including in Europe and Canada, due to the chip shortage. It has forecast it will produce 1.4 million fewer vehicles this year. The FIM-CISL union has said the impact of a semiconductor shortage on Stellantis' Italian production this year will be worse and longer-lasting than the damage to output caused by the COVID-19 pandemic in 2020.
