Mysterious Maserati test mule could be upcoming Alfa Romeo Giulia

Well well well, what have we here? The truth is that we don't know. It seems to be a Maserati Ghibli, but since that model is already out on the market, we're likely looking at something else. Just what is the question, and the answer likely lies in the wheelbase. While this test mule, spied undergoing cold-weather testing in northern Sweden, is clearly wearing the bodywork (and likely most of the mechanical bits) from the Ghibli, it's riding on a shortened wheelbase. Which tells us this could be one of two things: it's likely to be a test mule either for the upcoming Maserati Alfieri sports car, or for the new Alfa Romeo Giulia. The Alfieri was presented in concept form at the Geneva Motor Show back in March, foreshadowing a new sports car to serve as a halo model in the Maserati lineup. The production version is expected to be smaller and nimbler than the existing GranTurismo and positioned against the likes of the Porsche 911, Jaguar F-Type and Mercedes-AMG GT, to name just a few. The Giulia, meanwhile, is slated to be the first all-new Alfa Romeo since the arrival of the 4C last year and the Italian marque's first mainstream model since the launch of the Giulietta in 2010. The new sedan is expected to go after the likes of the BMW 3 Series and the new Jaguar XE, slotting in below the larger Maserati Ghibli that seeks to challenge the 5 Series and XF. If this is indeed a test mule for the new Alfa sedan, the quad tailpipes would seem, as our spy photographers point out, to indicate it's laying the groundwork for the GTA performance version. One way or another, there's something enticing to be coming soon from Italy, so watch this space.

Maserati Levante crossover not Jeep based after all?

Maserati has been teasing its crossover project since 2011, which is when it first showed off the Kubang concept (pictured above). Still, the production version, rumored to be called the Levante, remains a complete mystery. The CUV was first rumored to borrow the platform from the Jeep Grand Cherokee, but new rumors indicate that the Italian, luxury crossover might actually take the underpinnings from the Quattroporte and Ghibli.
In a brief interview, Maserati CEO Harald Wester told CNN Money that the Levante wouldn't use Jeep's platform. Motor Trend spoke with an unnamed Maserati engineer who confirmed the rumor. Officially, the company says that no decision has been made.
We can add this to another long list of rumors about the Italian CUV. It was originally supposed to be built at Chrysler's Jefferson North assembly plant in Detroit. Then, plans were changed to build it in Italy.

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.
