Maserati switching to in-house twin-turbo V6 and turbo four

Automotive News has been able to put some output figures to the two primary engines that will power Maserati's renaissance. Last year the Italian luxury brand sent notice that it would terminate its deal to with Ferrari to use the Maranello-sourced F160 3.0-liter twin-turbo V6 and F154 3.8-liter twin-turbo V8. As new Maserati models appear and current models are overhauled, the brand will begin installing either Maserati's own 3.0-liter twin-turbo V6, or an FCA-sourced 2.0-liter turbocharged four-cylinder. The V6 will greet the world from the middle of the MC20 supercar poised for debut in September, assuming nothing goes worse with the world than it already has. Rumor from Mopar Insiders and Allpar forums is that Maserati began building its V6 based on Alfa Romeo's 690T V6. Alfa Romeo puts the 690T in the Stelvio and Giulia Quadrifoglio, the engine's development having started seven years ago with Ferrari's F154 V8 as its heart. Tuned for speed, peak output could reach 542 horsepower. After making its home in the racy coupe, the V6 will also serve a new midsize Maserati crossover coming next year, as well as the next GranTurismo coupe and GranCabrio convertible. In the crossover, power is apparently limited to no more than 523 horses. In Maserati's new V6, one piece of technology that permits such high output and emissions friendliness is turbulent jet ignition (TJI). German supplier Mahle has been developing the technology for at least 10 years, and put it to use in Ferrari's Formula 1 engine about five years ago, after which Japan's Super GT manufacturers picked it up. Instead of a spark plug igniting fuel directly in the combustion chamber, TJI places the spark plug and an injector nozzle at the top of a "jet ignition pre-chamber assembly." The injector shoots a mist of gasoline into the pre-chamber, the spark plug fires, and the force of ignition in the pre-chamber sprays the combustion through tiny holes at the bottom of the pre-chamber into the cylinder as the piston rises. Mahle says the shorter burn and improved combustion spread means cleaner-burning gas engines that emit fewer emissions.   AN says that the "new V-6 engine will be 'electrified' in some form." It's not clear if that means all versions of the V6 will get some sort of hybrid assistance, or if — as had been thought — there will be a non-hybrid unit.

2021 and 2022 Maserati models recalled over fuel leak risk

Maserati is recalling a handful of 2021 and 2022 models to fix a problem that can cause a fuel leak. While the number of cars included in the campaign is relatively small, it covers every member of the company's lineup ranging from the entry-level Ghibli to the MC20 supercar. Documents published by the National Highway Traffic Safety Administration (NHTSA) explain that about 409 cars sold in the United States are fitted with a fuel line sensor housing that can crack and leak. It adds that this problem can reduce the engine's performance by not delivering enough fuel to the cylinders; alternatively, the leak can cause a fire, though the notice says that's only in "rare circumstances." There are 274 units of the 2021 and 2022 Levante, 88 examples of the 2021 Ghibli, 43 2021 Quattroporte sedans, and four 2022 MC20s affected. Maserati estimates that the Levante models included in the campaign were built between September 18, 2020, and October 4, 2021. For the Ghibli, the date range provided by the Italian firm is November 3, 2020, to June 7, 2021. Quattroporte models were built from October 28, 2020, to June 7, 2021, while the four MC20s were manufactured between July 12 and September 29, 2021. Maserati notes that it acted quickly: it found out about the problem on October 8, it opened an internal investigation into the part's supplier the following day, and it issued the voluntary recall on November 4, 2021. As of writing, there have been no accidents, injuries, or fatalities linked to the problem.  Maserati will replace the fuel line sensor housing in all affected cars free of charge. It will begin notifying owners on December 27, 2021. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

The List #0100: Drive the Italian Alps

The List travels to northern Italy to experience driving the Italian Alps. For this grand drive, we need a proper grand touring sports car. The Maserati Quattroporte fits the bill, with four doors, space for luggage, and all-wheel drive for those snowy mountain passes. But first our hosts make a quick stop at the Museo Casa Enzo Ferrari in Modena to take in an exhibit celebrating 100 years of Maserati. "The scenery is unbelievable," says host Patrick McIntyre. "If you're going to come all the way to Italy, rent a car and drive through [the Alps]." Join Jessi and Patrick as the check 'drive the Italian Alps' off of their list. Have an RSS feed?
