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.

Alfa Romeo Giulia to get Ferrari-related engine

Alfa Romeo has a long, proud history of using V6 engines in its coupes, sedans, and sports cars over the years, but as the new Giulia sedan approaches, the Italian marque is allegedly turning to Ferrari for its next six-cylinder. This is obviously not the first time a Ferrari-sourced or derived engine has been found under an Alfa's long hood. While 8C Competizione famously used a version of Ferrari's F136 V8 during its short run, the Giulia's new V6 will be offered on a much larger scale, slotting in above an entry level, four-cylinder turbo (likely the next-gen version of the 4C sports car's 1.75-liter engine). According to Autocar, the new V6 will be "specially developed for Alfa Romeo," and will be built at the Termoli engine factory alongside the new turbo four-cylinder. As for the rest of the Giulia, Autocar has been able to shine a light on a number of other details about the new midsizer. It will, thankfully, be rear-wheel drive, and designed to counter the "mostly cold and clinical" and soulless cars of the German competition, Maserati chief Harald Wester told AC. Some of the new sedan's structural elements will even be shared with Maserati's entry level model, the Ghibli. Most notable of all, though, is what the Giulia means for American consumers. After the limited-run 8C and the niche 4C, the new sedan will lead Alfa Romeo's long-awaited, large-scale return, where it will combat the popular BMW 3 Series, Mercedes-Benz C-Class, Audi A4, not to mention rivals like the Cadillac ATS and Lexus IS. Look for more on the Giulia next week when it's officially revealed in Milan.
