2014 Maserati Quattroporte goes on a night run

While it was in development, Maserati rolled out its 2014 Quattroporte for a little testing, but rather than slather the big luxury sedan in gobs of camouflage to protect from it prying eyes, engineers used the cover of darkness to conceal the vehicle's design. Then they made a video about their cleverness and posted it on the Internet. The team spent some time whipping around the Balocco Proving Ground with chief test driver Fabrizio Galvan at the controls to evaluate the sedan's new drivetrain, noise levels and handling in the real world.
We got our hands on the 2014 Quattroporte last month for a first drive ahead of the vehicle's North American debut at the 2013 Detroit Auto Show. You can read our impressions here, but first, take a look at the video below for a new glimpse at the machine's development.

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 teases MC20 prototype again reminiscing about the Targa Florio

Maserati spent its weekend reminiscing about victory in the 1940 Targa Florio, putting an MC20 prototype to work enhancing the gravitas of the anniversary. After winning the Targa in 1937, 1938, and 1939 with the Maserati 6CM and its 1.5-liter supercharged inline-six throwing 175 horsepower, the House of the Trident showed up in 1940 with the brand new 4CL powered by a 1.5-liter turbocharged four-cylinder cranking 220 hp. Luigi Villoresi, who'd driven the 6CM to triumph the year before, crossed the line first in the 4CL to close out European racing until the end of World War II. With a return to racing on the automaker's mind, Maserati took a camouflaged MC20 to the same Favorita Park roads that hosted the Targa. The soft-focus spy shots were taken in front of the Floriopoli stands, a stretch of bunting and banners not far from the Targa start line as historic competitors headed into the Sicilian mainland. The MC20 is as photogenic in these shots as all the others, and as mysterious. The automaker seems intent on making everyone wait until the September debut to for any details that the prototype doesn't put on display. Prime among enthusiast interest is the powerplant. With Ferrari shutting down its supply of engines to the fellow Modenese sports car maker, Maserati says its new mid-engined coupe will be "the first car to use [its] new engine, brimming with innovative technological contents, developed and built by Maserati in-house." Short odds figure on a molto potente twin-turbo V6 sending power to the rear wheels through an eight-speed dual-clutch transmission, the long money isn't afraid to bet on a 4.0-liter twin-turbo V8  to replace the F154 V8 that Ferrari provides. With race engineers undoubtedly sorting out a version for sports car racing as we speak, Maserati will certainly hope the competitive version matches the exploits of the 4CL. The vintage race car took pole in its first race, earned its first victory two races later, snatched up a bag of silverware before WWII, won the first race held in Europe after the war ended, and continued winning in 4CL and 4CLT trim until 1951 to take 31 total victories — nine more than the MC12 race car.
