2014 Maserati Quattroporte to get twin-turbo V6

As we wait for the Detroit Auto Show to get our up-close and in-depth look at the redesigned 2014 Maserati Quattroporte, some details are just starting to emerge about the car's powertrain, but nothing is official just yet. Autocar has posted a first drive of the new Quattroporte, finally spilling the beans about what motivates this sporty and luxurious sedan.
We already knew that the 2014 Quattroporte will offer two engines - a V6 and V8 - but what we didn't know is that both engines will get a pair of turbochargers and direct injection. Previously, we speculated that the smaller V6 would be supercharged, but this 3.0-liter V6 will get turbos instead helping it produce an estimated 410 horsepower. As for the larger 3.8-liter V8, this engine is said to produce 530 horsepower (confirming our previous report) to go with 479 pound-feet of torque; performance specs for the V8 include a top speed of 191 miles per hour and a 0-60 mph time of well under five seconds.
All cars will have a ZF eight-speed automatic transmission, and all-wheel drive will be optional allowing for all of the engine power sent to the rear wheel during normal driving and a full 50/50 split between front and rear axles when needed. As we suspected, the 2014 Quattroporte has grown in size to better compete with the Mercedes-Benz S-Class.

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.

Vastly Upgraded Italian Speed Sedan Kicks Off Brand Renaissance
The sixth-generation Maserati Quattroporte is big - and not just because it's 6.5 inches longer than before with a wheelbase that stretches 4.3 inches beyond its predecessor. The new Quattroporte is big also because it's a huge deal both for its segment and for Maserati. Just as FoMoCo is finally chucking $1 billion at Lincoln MoCo, so too is Fiat investing 1.2 billion euros ($1.55 billion at the time this writing) in Maser's future hopes of achieving the larger success we all have wished for it. And after a thorough drive over the intensely challenging mountain roads of France's Mediterranean coast, we can't deny that there's finally reason to put some faith in this long overdue investment.
The much-applauded outgoing Quattroporte enjoyed a reputation of being among the very fastest executive sedans of its day, all while delivering the sportiest overall ride and handling, even in base trims. Yet there was constant corporate-level dysfunction that kept all Maseratis from getting important upgrades or receiving much-needed investment support. So, the outgoing Quattroporte has up until now sort of languished nobly, largely resting on the laurels it earned when it launched way back in 2003.
