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.

2018 Maserati GranTurismo First Drive | Better with age?

There are not many rational reasons for owning a Maserati GranTurismo (or GranCabrio convertible, for that matter). Even Maserati admits this. The short list occupies a single paragraph. Firstly, the GranTurismo is not German. Don't laugh. For some people, that's enough. Secondly, it has rear-seat space and comfort that remains the class benchmark. Thirdly, its cabin is the place where art and craftsmanship meet. There are far more rational reasons to not buy one. Let's tick them off, since we're in the mood. Firstly, it's already had its tenth birthday. It's not jeepers-fast by today's standards and neither is it remotely frugal. It drives the back wheels through a six-speed transmission, so it has 50 percent fewer gear ratios than AMG. Also, the only thing light about it is the weight of its driver-assistance systems. The 4.7-liter GranTurismo and its roofless GranCabrio sibling prospered in the plus-minus ledgers early in their careers, but they now operate outside them, in the sketchbooks of translated emotion. The Pininfarina-designed body is still stunning, a decade on, from any angle. It's had some tickles on the front and rear bumpers to make the grille more like the one on the Alfieri concept car, there are new headlights in the same space and the aerodynamics have been cleaned up so it can streak beyond 186 mph. When we say "streak" we really mean "creep" because it tops out at 187 mph. It has air vents behind the front wheels now, but they're not functional, and neither are the three signature vents high up on the front fenders. Maserati's aero guys tested German cars with working air vents and found their aero contributions were minimal. The air inlet on the MC's is, though, and so are the twin hot-air outlets that give the carbon-fiber hood its exaggerated contours. The big news from the Powertrain Department is that it's been busy eliminating stuff, rather than doing new things. It simplified its life by killing off the entry-level 4.2-liter V8, so the only engine in the entire range now is the Ferrari-built 4.7-liter, 90-degree V8. Don't think of bolting in the torque-rich twin-turbo V6 motor from the Ghibli, Quattroporte or Levante – or the twin-turbo V8, either – since neither are available. The V8 also comes in just the 453 horsepower version, regardless of whether you like the standard GranTurismo Sport or shell out another $17,745 for the $150,570 GranTurismo MC.

Electric Maserati Grecale Folgore will have over 500 horsepower

Maserati is beginning to release details about its Folgore-badged range of EVs. We know that the battery-powered version of the next Gran Turismo will have over 1,200 horsepower, and Autoblog learned preliminary details (including output and range) about the Grecale Folgore. Due out in 2023, the electric Grecale will share its Giorgio platform with the gasoline-powered model. Pictured in the gallery above, the architecture will incorporate a 105-kilowatt-hour lithium-ion battery pack and a pair of electric motors for through-the-road all-wheel-drive. Federico De Medio, Maserati's head of vehicle validation, told us to expect over 500 horsepower and more than 300 miles of driving range. "We were able to install the battery pack in the lower part of the car while keeping the Giorgio platform, which is a very versatile architecture that can be multi-energy," he said. "I've heard people say, 'It can't underpin an EV!' Well, you can clearly see that it can." Maserati will rely on lightweight materials, like aluminum and carbon fiber, to partially offset the weight of the battery pack. It will give the Grecale a 400-volt electrical system, a solution chosen for its flexibility, and the motors that will power the SUV will not be the same units fitted to the Gran Turismo. Clearly, there is no one-size-fits-all answer to electrifying a portfolio of models as diverse as Maserati's. But, while electric cars make headlines, gasoline-powered cars make volume, and Maserati isn't giving up on that part of its range quite yet. It tentatively plans to offer only electric cars by 2030, but until then (and maybe even beyond then) it will let customers choose what they drive. "We are one of the few brands still making investments in two technologies: internal combustion and electric," said Bill Peffer, head of Maserati's American division. "People have asked us why. The reason is simple: We're adding products to the lineup, and the [EV] adoption curve is different in different parts of the world, so we're going to let the customer choose. The customer is going to decide what the rate is going to be, and we have the flexibility of ramping up or ramping down depending on demand. There's a long runway between now and 2030."
