The Maserati MC20's new Nettuno V6 is a high-tech showpiece

It's been more than two decades since Maserati was in the business of developing an in-house 90-degree V6 engine, and the last one it had traced its genealogy back 30 years. That story started in 1968, when Citroen took a controlling stake in Maserati, and the French requested that the Italians create an engine for the 1970 Citroen SM. Famed Maserati engineer Giulio Alfieri designed a 2.7-liter V6 producing 170 horsepower that could be built using Maserati's existing V8 tooling, hence the 90-degree angle. Alfieri then revised that V6 and bored it out to three liters, upping output to 187 hp, for use in the 1972 Maserati Merak. A decade later, Maserati – now owned by Alejandro de Tomaso, who had fired Alfieri — started with Alfieri's V6 philosophy when developing a mill for a new sports car. The resulting V6 unit, in 2.0-, 2.5-, and 2.8-liter displacements, was the first twin-turbocharged motor put into a production car. That car? The hot, gorgeous mess known as the 1984 Maserati BiTurbo. Almost 10 years on, the 1992 Maserati Ghibli II would get a 2.0-liter version of this 90-degree V6 making 306 horsepower. The 1995 Ghibli Cup turned that mill up to 330 hp, crowning the 2.0-liter V6 as the most power-dense engine in a production car, surpassing 1990s icons like the Jaguar XJ220 and original Bugatti EB110 (both 155 horsepower per liter). When the Ghibli exited production in 1998, Maserati ceded engine development duties to Ferrari by order of Fiat, which owned both automakers. 2022 Maserati MC20 View 47 Photos Nettuno, the new beating heart of Maserati Now we have the Nettuno, a 90-degree 3.0-liter V6 created to power Maserati's renaissance and making its debut in the chunky, aerodynamic form known as the MC20. At 630 horsepower and 538 lb-ft of torque, the engine almost picks up where the Ghibli Cup left off: with 210 horsepower/liter, the Nettuno is one of the most power-dense in the world. The Bugatti Chiron, Ford GT, and McLaren 756LT don't crack 200 hp/l. The only production cars in the ballpark are Euro specials like the Mercedes-AMG A45 (208.4 hp/l). Beyond it are seven-figure hypercars like the SSC Tuatara (229 hp/l) and Koenigsegg Jesko (256 hp/l on gas, 320 hp/l on E85). The word we're looking for in Italian is bentornato. Welcome back, Maserati.

2019 BMW M850i xDrive: How it compares on paper with other GT coupes

Although the hot new vehicles for the rich seem to mainly comprise SUVs and supercars, the neglected luxury GT coupe segment is starting to see some life again. The latest to add a spark to this set is the 2019 BMW M850i xDrive. It goes on sale later this year, and revives the 8 Series that's been dead since the 1990s. The first version available to Americans will be one with a twin-turbo 4.4-liter V8, with other versions likely following. Before it launches, we wanted to get a lay of the grand-touring land and see how the new BMW stacks up to the competition in performance, practicality and price. While some of these models have higher-performance or more-affordable iterations, we picked the versions that would be the closest match to this 8 Series model. They include the 2019 Lexus LC 500, 2018 Mercedes-Benz SL 550, 2018 Mercedes-Benz S 560 Coupe and the 2018 Maserati GranTurismo. We will also provide some short summaries on our experiences with these cars, but to get a full picture of each model, be sure to check out their full reviews. And if you want to compare any of these cars with models you don't see here, be sure to try out our car comparison tool. Engines, transmissions and performance On paper, the BMW M850i xDrive is clearly the performer of the group. It has the most power and torque at 523 horsepower and 553 pound-feet. Coupled with all-wheel-drive and an eight-speed automatic, the car is able to overcome its relatively portly 4,478-pound curb weight to hit 60 mph in a scant 3.6 seconds. That's more than half a second quicker than the lightest car in the group, the Mercedes-Benz SL550, which weighs 4,012 pounds. The other three vehicles are in the low- to mid-4-second range to 60 mph. Though the Maserati is the slowest to 60 mph, it does boast the highest top speed of 186 mph. The M850i and SL 550 are electronically limited to 155 mph, while the Lexus is limited to 168 mph. The Mercedes S 560 has the lowest top speed at an electronically limited 130 mph.

The BMW and Mercedes resort to forced induction, whereas the Lexus and Maserati choose to stay naturally aspirated. This is likely why the Germans break 500 pound-feet of torque, while the others don't make it to 400. Also interesting is the spread of gear quantity. The Maserati has just six ratios to choose from, and the Lexus has a whopping 10.

Maserati dedicates MC20 prototype to Stirling Moss

Maserati is paying tribute to Stirling Moss, the British race car driver who died on April 12, by wrapping one of its MC20 test mules in commemorative camouflage. The mid-engined sports car is due out in September 2020. It's a fitting homage, because Moss logged thousands of miles behind the wheel of Maserati race cars like the 250F (which he called one of his favorites), the 300S, and the famous Tipo 61 Birdcage. It's difficult to add retro-inspired styling cues to the camouflage applied to a prototype, but Maserati pulled it off well. It added simple, eye-catching red graphics of the racer's name to the MC20's rear end and over its wheel arches. The rest of the car is plastered in a Maserati-branded black and white wrap, though there's a red trident emblem on the roof. On a secondary and more lasting level, the images published by Maserati give us a better look at the MC20 — a name that likely won't be retained for production — than previous spy shots. The four round taillights fitted to earlier prototypes have been replaced by a pair of seemingly production-bound horizontal units. We can see the outline of its rear window, and the vents that let hot air escape the engine compartment. The rear panel is held down by four pins. Its front end remains relatively well hidden, though we spot a grille that's low and wide. "Sir Stirling Moss would certainly have liked the new MC20," Maserati summed up. It also reaffirmed its commitment to returning to "a leading role" on the racing circuits, meaning we'll likely see the MC20 driving flat-out on some of the world's greatest tracks shortly after it makes its debut. It was scheduled to break cover in May, but its unveiling was pushed back until September due to the coronavirus lockdown measures. When it arrives, the MC20 will inaugurate a twin-turbocharged V6 engine developed in-house and allegedly tuned to deliver over 600 horsepower. Unverified rumors indicate a hybrid model will join the lineup a little later in the production run with at least 700 horsepower on tap. It will be the first in a long line of new Maserati models, including the next-generation GranTurismo (which will again spawn a convertible) that will be available with an electric powertrain. The coupe will arrive in 2021, while the roadster should appear by the end of 2022. Related Video:     Featured Gallery Maserati MC20 Stirling Moss Spy Photos Maserati Luxury Performance stirling moss
