Maserati to show GranCabrio MC in Paris

Maserati sure seems to be milking the GranTurismo franchise for all its worth these days. In addition to plenty of limited editions and sport models for both the coupe and convertible, Maserati recently launched the MC version of the hardtop. Now, ahead of its debut at the Paris Motor Show, the Modenese automaker has dropped details on its latest iteration of the GT platform, the GranCabrio MC.
Visually, the droptop's most noticeable change is its new face, which has been lifted directly off the MC Stradale coupe. This means the car is a full 48 millimeters longer than the standard and Sport versions of the GranCabrio, but we like the decidedly more aggressive look to that big ol' schnoz. The large rear spoiler has also been reworked for the MC, providing even more downforce to keep that large body firmly glued to the road.
Maserati has not released powertrain details, but we assume that the GranCabrio MC uses the same 4.7-liter Ferrari-sourced V8 as the MC coupe, good for 444 horsepower and 376 pound-feet of torque, mated to a six-speed automatic transmission.

2023 Maserati MC20 Cielo First Drive Review: Fine-tuned from the top down

CATANIA, Sicily — “We wanted to give the Cielo the same behavior and character as the MC20 but with the sharp edges made a little smoother,” explained Federico Landini, the man in charge of the MC20Â’s development. Cielo is the name Maserati chose for the convertible MC20 — it means “sky” in Italian and sounds less generic than Spider, Spyder or another arachnid-inspired label. This new version of MaseratiÂ’s first supercar in over a decade slots in the range as a softer, more touring-oriented alternative to the coupe. While the two MC20s look a lot alike, Maserati ensured the Cielo has its own personality. Same heart, different bones Like the MC20 coupe, the Cielo is powered by MaseratiÂ’s excellent 3.0-liter Nettuno V6 engine, which is twin-turbocharged to develop 621 horsepower at 7,500 rpm and 538 pound-feet of torque from 3,000 to 5,500 rpm. While 600+ horsepower is par for the course in this segment, achieving that number with six cylinders is rather unusual. The engine develops 207 horsepower per liter of displacement. If every engine offered this level of power density, weÂ’d have a 414-horsepower Volkswagen Golf GTI to play with. This engine also powers variants of the Grecale SUV, though the MC20 models use a dry-sump lubrication system. Landini told me Maserati felt confident sending a V6 into a ring dominated by rivals with eight or more cylinders because it fitted the engine with both direct and indirect fuel injection systems. This innovative technology — which traces its roots to Formula One racing — adds pre-chambers inside the cylinder head and a second set of spark plugs to the 90-degree V6 to provide a 100-horsepower boost. Mid-mounted, the Nettuno spins the CieloÂ’s rear wheels via an eight-speed automatic transmission linked to a pair of steering-wheel-mounted shift paddles. Maserati quotes a 0-62-mph time of a little under 3 seconds and a top speed of approximately 199 mph, so the coupe is slightly quicker and faster. Giving up two or three tenths of a second to highway speeds and forfeiting a few miles per hour at the top end is a fair trade for unlimited headroom. Going topless also makes the Cielo about 143 pounds heavier than the coupe: it tips the scale at roughly 3,400 pounds, which remains reasonably light.

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.
