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.

2020 Maserati Quattroporte S Q4 Driveway Test | Are you louder than a Dodge Challenger?

The 2020 Maserati Quattroporte is an Italian luxury sedan that comes in several flavors. Recently, we've had a couple pass through the Autoblog short-term loaner fleet, and I decided to take the opportunity to record an exhaust clip and see whether it's louder than my 2013 Dodge Challenger SRT8 392.  You thought we were done with this, didn't you? Hah.  The Maserati is a bit of an odd duck. Like the Alfa Romeo Giulia Quadrifoglio, which kicked off this series, it's an Italian sedan powered by a turbocharged V6 producing a respectable 430 horsepower. Unlike the four-cheese, the Quattroporte in our garage was not its high-performance variant. In fact, if it were, it would have a V8, as all things should. I'm kidding. Or am I? Sadly, the V6 probably holds the S Q4 back in this particular "test," which resulted in a reading of 78.2 decibels. That's far short of my Challenger, which checked in at 85.7 dB and remains our reining champion ... for now.  The Quattroporte is in reasonably decent company, though, thanks to the Porsche Cayenne S Coupe, which produced a similar result. Yeah, that's an SUV, but this is a luxury car, right? So the missions are similar. Heck, they even make about the same power.  These tests are only vaguely scientific, and I conduct them using a free Android OS sound-measuring app and the mostly enclosed space of my personal garage. For those who are unfamiliar with my methodology (and again, I use that term somewhat loosely), you can refer back to my previous tests with the Alfa or the Cayenne S Coupe for more details.  Or, just click the pretty links to hear engines go burble-burble; it's entirely up to you.  Disclaimer: Autoblog accepts vehicle loans from auto manufacturers with a tank of gas and sometimes insurance for the purpose of evaluation and editorial content.
