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 teases us with its MC20 testing in the snow

It may be feeling spring-like here in parts of the United States, but there was still plenty of snowpack in Livigno, Italy, when Maserati took its forthcoming MC20 supercar out for a photo session during some cold-weather testing at Ghiacciodromo Livigno.  "During its cold-weather mission, the super sports car was tested to evaluate engine cold starting, the low-temperature performance of its elastic components and the car’s handling on cold and low-grip asphalt surfaces," said the accompanying release. "The test is also performed to verify correct functioning of the Climate Control System in cold conditions; tests were also conducted on the battery, suspensions and brakes." Just reading that, you'd think their trip was all business. Indeed, this is the latest stop on the MC20's worldwide durability testing tour, but from the playful scenes we see here, it's pretty obvious that the engineers had their share of fun giving the MC20's suspension and powertrain a workout in the low-grip environment.  2022 Maserati MC20 winter testing View 5 Photos The MC20 is a mid-engined, 621-horsepower, mid-engine super-coupe that was built with the race track in mind. Power comes from a new V6 that is the first in the company's new "Nettuno" (Neptune) engine series. The twin-turbocharged mill produces 210 horsepower/liter, making it one of the most power-dense engines in the world. It was designed, developed, and produced in-house by Maserati's engineers despite sharing some of its fundamental design with other performance engines in its corporate family.  Maserati has only unveiled the street-legal variant of the MC20 seen here so far, but we expect it won't be long before we hear more about its competition aspirations. 

Autocar compares new Maserati Quattroporte to Jaguar XJ

Autocar's Steve Sutcliffe took the 2014 Maserati Quattroporte on a spin along snowy mountain roads to test it for a specific brief: as a limousine for the chauffeured class. It's sporting credentials are impressive: Twin-turbocharged 3.8-liter V8, 532 horsepower, 475 pound-feet of torque in casual circumstances that rises to 532 lb-ft in overboost, a 0-to-60 mile-per-hour sprint of 4.7 seconds and a top speed of 191 mph.
However, citing Maserati's desire to not just increase its sales to 50,000-per-annum by 2015, but to sell many more of its cars in China, Sutcliffe wanted to find out if the livery side of the Quattroporte could match its sport sedan side. So after taking the pilot's seat and trying out the sport settings, Sutcliffe hops in back to test out the CEO's seat.
Then he compares the Quattroporte against the long-wheelbase Jaguar XJ with its supercharged V8, a sedan that's 15,000 pounds less expensive than the Maserati. It doesn't take long for him to find that one of them is a clear winner when it comes to transporting VIPs. To find out which one, enjoy the video below.
