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.

Mysterious Maserati test mule could be upcoming Alfa Romeo Giulia

Well well well, what have we here? The truth is that we don't know. It seems to be a Maserati Ghibli, but since that model is already out on the market, we're likely looking at something else. Just what is the question, and the answer likely lies in the wheelbase. While this test mule, spied undergoing cold-weather testing in northern Sweden, is clearly wearing the bodywork (and likely most of the mechanical bits) from the Ghibli, it's riding on a shortened wheelbase. Which tells us this could be one of two things: it's likely to be a test mule either for the upcoming Maserati Alfieri sports car, or for the new Alfa Romeo Giulia. The Alfieri was presented in concept form at the Geneva Motor Show back in March, foreshadowing a new sports car to serve as a halo model in the Maserati lineup. The production version is expected to be smaller and nimbler than the existing GranTurismo and positioned against the likes of the Porsche 911, Jaguar F-Type and Mercedes-AMG GT, to name just a few. The Giulia, meanwhile, is slated to be the first all-new Alfa Romeo since the arrival of the 4C last year and the Italian marque's first mainstream model since the launch of the Giulietta in 2010. The new sedan is expected to go after the likes of the BMW 3 Series and the new Jaguar XE, slotting in below the larger Maserati Ghibli that seeks to challenge the 5 Series and XF. If this is indeed a test mule for the new Alfa sedan, the quad tailpipes would seem, as our spy photographers point out, to indicate it's laying the groundwork for the GTA performance version. One way or another, there's something enticing to be coming soon from Italy, so watch this space.
