Maserati details the new, 630-hp V6 that will power its mid-engined MC20 coupe

Maserati is done leaning on former sister company Ferrari for technical support. It has unveiled the six-cylinder engine it designed and will build in-house to power the MC20 supercar that's scheduled to make its debut later in 2020. Ferrari's willingness to develop and/or build engines for Maserati shrank significantly when it split from former parent company Fiat-Chrysler Automobiles (FCA) in early 2016 and became independent. Insiders knew the division would be spun off, so they began designing Maserati's new engine (which is called Nettuno) in 2015 and accelerated the process in 2017. It's a 90-degree, 3.0-liter V6 with a dry sump and a twin-spark, pre-chamber ignition system rooted in racing. In this application, it's twin-turbocharged (the turbos are mounted on the outside of the engine rather than in the middle of it) and it's equipped with both direct and indirect fuel injection.  All told, the 485-pound Nettuno engine develops 630 horsepower at 7,500 rpm and 538 pound-feet of torque between 3,000 and 5,500 rpm. It continues revving to a redline of 8,000 rpm.  Matteo Valentini, Maserati's chief engineer, explained the Nettuno engine will ultimately power the company's entire range of vehicles, though he stopped short of naming the specific models that will use it after the MC20. He added the six-cylinder will "bring Maserati back into the world of racing," meaning its output will likely grow in the not-too-distant future. We'll learn more about the engine when the MC20 makes its debut September 9. What remains to be seen is whether Maserati will replace the V8 available in the Levante and the Quattroporte, or if it will surf the downsizing wave sweeping across the industry. Developed jointly with Ferrari in the early 2010s, that engine makes 590 horsepower when it's bolted in the Levante Trofeo's bay, meaning its output is eclipsed by the Nettuno V6's. Both engines are built around a 90-degree architecture, so the 3.0-liter V6 could turn into a 4.0-liter V8 if it's modular enough to gain a pair of cylinders — and if Maserati sees a market for another eight-cylinder.

Stirling Moss-crashed 1956 Maserati 450S to be auctioned in Monaco

RM Auctions has some very special and expensive Italian sportscars of the 50s and 60s consigned for its auction in Monaco on May 10, but the one that currently carries the highest estimated value at between 4 and 5.5 million euros ($5.5 - $7.5 million) is a 1956 Maserati 450S with some very interesting provenance.
The Maserati started its life as a six-cylinder 350S that Stirling Moss drove in the 1956 Mille Miglia race. Unfortunately, the brakes failed, and it crashed into a tree and nearly into a ravine. Moss and his co-driver weren't injured, but the car was kaputt.
Maserati repaired it and used the chassis as a test mule for its new 5.7-liter V8 racecar called the 450S. It featured an extended wheelbase to fit the larger engine and a new body with a single seat. The racer hit the track again at the hands of Moss and Juan Manuel Fangio in the 1957 Buenos Aires 1000 KM but retired with transmission issues. Later that season, it crashed again at the 1957 Mille Miglia at the hands of driver Jean Behra. After that, the car sat around the workshop until it was sold without an engine in 1965.

Maserati GranCabrio revealed in high-output Trofeo trim

As has been the tradition with Maserati over the past couple of decades, now that the four-seat GT coupe has launched, it's time for the drop-top version. And this latest convertible adopts the same name as its predecessor: GranCabrio. It is, in almost every respect, the same car as the GranTurismo, but with a fabric roof and a bit more weight. Said roof is available in five colors: a navy blue, dark red, black, grey and "greige." It is indeed fabric in order to fold more compactly and allow for cargo space with the top folded, though it will still take up a bit of trunk space when retracted. It also folds quickly at just 14 seconds, and it will come back up in 16. Operation of the top can be done at speeds up to 31 mph. To keep occupants comfy in all temperatures with the top down, the front seats have air vents in the seat backs to blow air onto the neck. Optionally available is a fold-open wind blocker that fits behind the front seats, though it can't be used with rear occupants. The soft top does bring some extra weight, around 220 pounds compared to the equivalent coupe. Maserati didn't specify exactly what contributes to the gain – whether it's more just top components or if some of it comes from chassis reinforcements (both seem likely). Interestingly, the extra weight actually gives the GranCabrio slightly better balance than the GranCoupe. The drop-top's front and rear weight distribution is 51/49 to the coupe's 52/48. Maserati is only offering the GranCabrio in the top-spec Trofeo internal-combustion trim for now. That includes the twin-turbo 3.0-liter V6 making 542 horsepower and 479 pound-feet of torque, eight-speed automatic transmission and all-wheel drive. The weight does ever so slightly blunt acceleration, dropping it by 0.1 second to 3.6 compared to the GranTurismo Trofeo. The same staggered 20-inch front and 21-inch rear wheels and Brembo brakes carry over from the coupe, too. And while the Trofeo is the only version for now, Maserati notes that the chassis remains designed for internal combustion and electric power, so an all-electric Folgore and more entry-level Modena gas-powered models will likely be added later. Maserati did not give a specific time for when the GranCabrio will hit dealers, but it should be sometime this year. Pricing is also a mystery, but should carry a premium over the GranTurismo coupe.
