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.

FCA inline-six rumored to be real, headed for Jeep Wagoneer

In September, Allpar reported that that clues being dropped at Fiat- Chrysler headquarters, in the carmaker's factories, and on engineer resumes pointed to the development of an inline six-cylinder engine. The site has just proclaimed the rumor is reality, writing that the straight-six, "turbocharged to meet or beat 5.7 Hemi power ratings, with a smoother torque curve, is on the way." The motor's first outing is expected to be either the next-generation Jeep Grand Cherokee, debuting perhaps next year, or the Jeep Wagoneer, debuting in 2020 or 2021. "Tornado" is the purported codename for the power plant said to be just under three liters in displacement, expanding the family begun with the Global Medium Engine 2.0-liter turbo codenamed Hurricane. Engine bay constraints and a long use horizon mean engineers won't simply add two more cylinders to the GME, however. Allpar says the brief is to keep the Tornado GME-T6 — the alphanumeric for "turbocharged six" — no more than three inches longer than the Tigershark 2.4-liter four-cylinder. That means "major design changes" that could include a space-saving head, more closely spaced cylinders, and no cylinder liners. An FCA division called Comau could be called on for its "SmartSpray" plasma lining technology. Allpar muses that the standard version of the engine for Chrysler, Dodge, Jeep, and Ram could get a single twin-scroll turbocharger. Performance trims for Alfa Romeo and Maserati could get different heads and maybe twin turbos, an SRT version might also get both those tweaks. History shows that the Italian versions would make changes to the block, as well. Even so, the Tornado would be less expensive than any Ferrari-supplied V6. A straight-six would put FCA in company with current adopters BMW and Mercedes-Benz, future users like Jaguar, and perhaps Aston Martin. The engine would span the widest range of use cases in the U.S. carmaker's portfolio, though. Potential applications include being a base engine for Ram trucks, serving double duty as a base engine and 5.7-liter Hemi replacement for the Dodge Charger and Challenger, working in the high-end Jeeps, and as a properly hot trim — with Ferrari-designed heads — in the luxury Italian sports cars. The Alfa Romeo Giulia begs for just such motivation to fill the gap between the 280-hp, $42,695 Ti Sport RWD and the 505-hp, $73,700 Giulia Quadrifoglio RWD. And a twin-turbo inline-six in a Maserati Alfieri would stack up nicely with the Germans.

2017 Maserati Quattroporte First Drive

When German companies launch a new luxury sedan, they chat about more power, better economy, and leveraged links to Silicon Valley's hottest microchip and graphics powerhouses. It's not like that in Italy. The Mediterranean peninsula only has one authentic maker of luxury sedans, and cutting-edge consumer technology has never been Maserati's forte. Beautiful cars, sure. Compelling engine notes, yup. The prioritization of handling emotion above cornering speed and even ride quality? Absolutely. Three years ago Maserati thought that blueprint would be enough for its all-new Quattroporte. It wasn't. For starters, the car wasn't beautiful. Compared to the filigreed purity of its predecessor, the QP (as they call it in Modena) looked awkward, even clunky. A big part of that was the sheer scope of the 124.8-inch wheelbase, which made it nigh impossible to deliver the proportional elegance and unfussed panel pressings of its predecessor. Still, the added length provided rear legroom that takes surveyors to measure. More important than what it had (and whether that was good or bad) was what it didn't have. There was no button on the remote to open the trunk, no self-parking system, no reversing camera, definitely no 360-degree camera setup, no radar cruise control, no semi-autonomous steering, and no modern navigation or infotainment. By far the biggest Maserati (at 207.2 inches, it dwarfs most of the standard versions of almost any sedan, anywhere), the Quattroporte now has some small visual changes and enough driver-assistance stuff (like radar cruise) to bring it up to German levels. At least, that's the on-paper argument. Not one of the 2017 model's visual upgrades is metallic. The changes include a new plastic grille (inspired by the design language of the Alfieri concept car), updated lights, and some very subtle differences between the sportier GranSport and the more luxurious GranLusso versions, two new trim packages. The aero guys have been busy, too, with a flat floor and a new Air Shutter that lowers drag by 10 percent and by itself improves the fuel consumption by three percent (anything else is down to stop-start). In a tech, tech, tech world, the Quattroporte is the anti-Tesla. There are no plans to give the big boy any form of hybrid power much less a plug-in hybrid powertrain. Maserati's engineers look at you funny for mentioning hydrogen fuel cell or battery-electric power.
