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.

Maserati confirms the Grecale SUV will get a high-performance version

Maserati will parachute its second SUV, the Grecale, into territory controlled by the Porsche Macan. It hasn't unveiled the model yet, but it has already confirmed a fire-breathing high-performance variant is in the pipeline. "We will have a Trofeo version of [the Grecale], we will have a Modena version of that. We will have a GT version," revealed William Peffer, the CEO of Maserati's North American division, in an interview with The Drive. While he stopped short of revealing specifications, Maserati saves the Trofeo name for its quickest and most powerful models. As of writing, all of its cars with the exception of the MC20 are available in Trofeo tune. They're powered by a twin-turbocharged, 3.8-liter V8 engine — even the smaller Ghibli — and they gain a number of chassis tweaks as well as several model-specific styling cues. We expect the Grecale will get a similar treatment. One ingredient of the traditional Trofeo recipe that the Grecale might not be cooked with is the V8. It's an older engine, and we're not sure that an eight-cylinder fits in the engine bay. Rumors claim the model will ride on an evolution of the Giorgio platform that Alfa Romeo's Stelvio and Giulia are built on, so the top engine might be a V6. Maserati is nearly done fine-tuning the Grecale. It will unveil the model in November 2021, and sales will start in time for the 2022 model year. Additional details about the firm's next SUV will emerge in the coming months. Related Video This content is hosted by a third party. To view it, please update your privacy preferences.

Ram/Jeep Ecodiesel engine has Maserati roots

The 3.0L turbodiesel V6 in the 2014 Ram 1500 EcoDiesel earned a slot on Ward's Automotive 2014 10 Best Engines for its power, fuel economy and refinement. In a piece looking at how Fiat subsidiary VM Motor developed the engine, Ward's also makes note of the fact that the same lump goes in diesel versions of the Maserati Quattroporte and Ghibli. They're tuned a bit differently, naturally, with the QP putting out 275 horsepower and 442 pound-feet of torque, the smaller, lighter Ghibli making do with the same number of horses but a lower torque output of 420 lb-ft.
The 240 horsepower and 420 pound-feet put out by the oil-burning six-cylinder in the Ram was tamed with a host of advances, but it appears that Ram hasn't tamed demand: the initial allocation of 8,000 engines was spoken for within three days of the truck going on sale. Head over to Ward's to read the story of how Ram worked out the equation light-duty-pickup + diesel = success.
