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 expands Quattroporte cable recall to 1,000 units

It was nearly two years ago that Maserati issued a recall for a number of Quattroporte sedans. At the time, the recall only affected 63 units in the United States. But now the Italian automaker has broadened that campaign to include nearly 1,000 examples across the country. The issue in question is related to the battery positive cable for the alternator and starter motor, the insulating cap of which may not have been installed correctly. The cable may not have been secured properly in the engine bay, too. According to the statement below from the National Highway Traffic Safety Administration, the problem could increase the likelihood of the cable shorting out, causing the wiring harness to overheat and potentially start a fire, or the engine to stall and potentially cause the vehicle to crash. The expanded recall still only affects certain examples of the 2014 Maserati Quattroporte GTS with the V8 engine – namely those manufactured between October 1 and December 31, 2013. That now includes an estimated 984 vehicles in the United States, the owners of which can expect to hear from their local dealer to have the cable inspected and, if necessary, replaced. Related Video: RECALL Subject : Starter Motor Cable may Short to Ground Report Receipt Date: OCT 21, 2015 NHTSA Campaign Number: 15V686000 Component(s): ELECTRICAL SYSTEM Potential Number of Units Affected: 984 Manufacturer: Maserati North America, Inc. SUMMARY: Maserati North America, Inc. (Maserati) is recalling certain model year 2014 Quattroporte GTS V8 vehicles manufactured October 1, 2013, to December 31, 2013. In the affected vehicles, the battery positive cable for the alternator and starter motor may not have its insulating cap installed properly at the starter motor. Additionally, the cable may not be adequately secured in the engine bay. These factors may result in the cable shorting to ground. CONSEQUENCE: If the battery positive cable shorts to ground, the wiring harness may overheat, resulting in a fire. The car also may stall, increasing the risk of a crash. REMEDY: Maserati will notify owners, and dealers will inspect the vehicle to verify that the starter motor cable has a properly installed protective cap and that the cable is adequately secured. If not, the starter motor cable assembly will be replaced. These repairs will be performed free of charge. The recall is expected to begin November 11, 2015.

Maserati GranTurismo successor to be smaller, fight Porsche 911

The Chevrolet Corvette, Jaguar F-Type and Porsche 911 all belong to a club that shuns the Maserati GranTurismo as an outsider. You see, those three key sports cars all measure within an inch of one another in length - 176 to 177 inches and change - while the Maserati comes in at over 192 inches. Naturally, there's extra length between its wheels, as well.
While those extra inches would seemingly pay dividends in interior roominess and storage space, those are not exactly the most important attributes in the segment, which values proper proportions and proper driving feel over all else. All of this is why it comes as little surprise that Maserati is working on a smaller version of its two-door sports car platform when the next generation is ready in roughly three years.
According to Motor Trend and echoing rumors we've heard in the past, the smaller model will be known as the Gran Sport while a larger model will still be called GranTurismo in coupe form and GranCabrio in convertible guise. We're told, again, to expect Maserati's new 404-horsepower supercharged V6 engine as standard, while the V8 would still be a possible option.
