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 video sheds a little light on mid-engined MC20 coupe

Maserati is preparing to unveil the MC20, its first new model since the Levante made its debut in 2016. It released a short video to whet our appetite before the mid-engined coupe makes its global debut on September 9. Posted on its official Twitter account, the five-second video does an excellent job of keeping the MC20's design under wraps, but it helps us decode what's lurking under the camouflage. It suggests Maserati stylists don't have a straight-edge in their arsenal of tools, because nearly every surface looks deliciously curved. We also get a quick glimpse at the vents chiseled into the hood, and at the air intakes positioned over the rear wheel wells. Out back, the coupe will feature louvers over the rear window, according to a different video posted on the company's Facebook page. We'd say it's safe to bet the cabin will receive the digital rear-view mirror that's slowly making its way across the Fiat-Chrysler Automobiles (FCA) portfolio. Louvers have never stopped carmakers from hanging a conventional rear-view mirror above the front passengers, but the MC20's represent a golden opportunity for Maserati to flex its technology muscles. Whether they'll be standard or optional is up in the air. Although Maserati is trickle-feeding us clues, earlier spy shots taken near its headquarters in Modena give us a much better look at the MC20. Its proportions reveal its mid-engined layout, and even the camouflage can't hide the low-mounted oval grille with the firm's trident emblem. It's a styling cue that subtly links the MC20 to the firm's past models, like the race-winning Tipo 61 (also known as the Birdcage) built from 1959 to 1961. This content is hosted by a third party.

Power for the MC20 will come from a 3.0-liter V6 engine developed in-house and twin-turbocharged to 630 horsepower and 538 pound-feet of torque. Called Nettuno internally, the 90-degree six-cylinder will have an 8,000-rpm redline, and it will spawn a track-only engine that will power Maserati's future race cars. Unconfirmed rumors claim the MC20 range will later grow to include a hybrid variant with at least 700 horsepower on tap, and a convertible. Maserati is investing significant resources into the development of electric powertrains, the next-generation GranTurismo will run exclusively on batteries, so we wouldn't be the least bit surprised if Maserati delivers an MC20 without exhaust pipes sooner or later.

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.
