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 video sheds a little light on mid-engined MC20 coupe

Maserati is preparing to unveil the MC20, its first new model since the Levante made its debut in 2016. It released a short video to whet our appetite before the mid-engined coupe makes its global debut on September 9. Posted on its official Twitter account, the five-second video does an excellent job of keeping the MC20's design under wraps, but it helps us decode what's lurking under the camouflage. It suggests Maserati stylists don't have a straight-edge in their arsenal of tools, because nearly every surface looks deliciously curved. We also get a quick glimpse at the vents chiseled into the hood, and at the air intakes positioned over the rear wheel wells. Out back, the coupe will feature louvers over the rear window, according to a different video posted on the company's Facebook page. We'd say it's safe to bet the cabin will receive the digital rear-view mirror that's slowly making its way across the Fiat-Chrysler Automobiles (FCA) portfolio. Louvers have never stopped carmakers from hanging a conventional rear-view mirror above the front passengers, but the MC20's represent a golden opportunity for Maserati to flex its technology muscles. Whether they'll be standard or optional is up in the air. Although Maserati is trickle-feeding us clues, earlier spy shots taken near its headquarters in Modena give us a much better look at the MC20. Its proportions reveal its mid-engined layout, and even the camouflage can't hide the low-mounted oval grille with the firm's trident emblem. It's a styling cue that subtly links the MC20 to the firm's past models, like the race-winning Tipo 61 (also known as the Birdcage) built from 1959 to 1961. This content is hosted by a third party.

Power for the MC20 will come from a 3.0-liter V6 engine developed in-house and twin-turbocharged to 630 horsepower and 538 pound-feet of torque. Called Nettuno internally, the 90-degree six-cylinder will have an 8,000-rpm redline, and it will spawn a track-only engine that will power Maserati's future race cars. Unconfirmed rumors claim the MC20 range will later grow to include a hybrid variant with at least 700 horsepower on tap, and a convertible. Maserati is investing significant resources into the development of electric powertrains, the next-generation GranTurismo will run exclusively on batteries, so we wouldn't be the least bit surprised if Maserati delivers an MC20 without exhaust pipes sooner or later.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
