Maserati puts an F1 spin on old tech to make 621 hp from a 3.0L engine

first_img Wow! Double-wow! A whopping 621 horsepower from only three litres!That’s more than two hundred horsepower per litre of displacement, a truly phantasmagorical figure considering that a) not a decade ago, 100 hp-per-litre was considered extraordinary; and b) the Nettuno is not (quite) a race engine.While you won’t see it on the track, it will, however, power the next generation of Maserati’s MC20 supercar, its 621 horses and 538 pound-feet of torque likely to generate Ferrari Pista-like performance. Speaking of Ferrari, the Nettuno powertrain is a radical departure for Maserati, as it is not some Maranello hand-me-down, but designed in the company’s own Innovation Lab in Modena. To get to that incredible power figure, the 90-degree V6 uses a Formula-1-inspired pre-combustion chamber. For those unfamiliar with what Formula 1 calls leading-edge technology, just go way back in automotive history to the ‘70s and look up the Honda Civics of the day.RELATED Created with Raphaël 2.1.2Created with Raphaël 2.1.2 The new Maserati-developed 3.0-litre ‘Nettuno’ V6  Maserati Trending Videos Cadillac CT4 uses innovative turbo tech to increase torqueIn their bid to get more power from less fuel, current F1 racers use Honda CVCC-like – and you truly are dating yourself if you remember that CVCC stood for “Compound Vortex Controlled Combustion” – technology that places a tiny pre-combustion chamber right above the main cylinder.Now the current form of the pre-chamber is much advanced, but the principle remains the same: the small pre-chamber gets fed a “rich” fuel mixture while the much larger main combustion chamber below is fed a “lean” mixture. The main spark plug fires the easily-lit fuel-heavy air in the pre-chamber and then the sends jets of burning gasses through some tiny, precisely located holes to light the leaner, more-reluctant-to-burn fuel in the main combustion chamber.Created with Raphaël 2.1.2Created with Raphaël 2.1.2The new Maserati-developed 3.0-litre ‘Nettuno’ V6 advertisement Maserati We encourage all readers to share their views on our articles using Facebook commenting Visit our FAQ page for more information.

Princess Diana’s humble little 1981 Ford Escort is up for auction An engagement gift from Prince Charles, the car is being sold by a Princess Di “superfan” It must work a charm, because the Nettuno makes only 40 less horsepower than a Ferrari 488 despite having two fewer pistons and a whole litre less displacement. Even the Pista version of Maranello’s latest supercar – massaging 710 hp from 3.9 litres of V8 – fails to match the Maserati’s incredible specific output — 182 horsepower-per-litre for the top-of-the-line 488 versus the 207-hp-per-litre of Maserati’s Nettuno. Maserati claims this is the first road-going use of F1 ‘stratified’ combustion. Trending in Canada In the Maserati version of the high-tech combustion, this is done to achieve maximum power while minimizing fuel consumption and CO2 emissions. To make this all work, the Nettuno combines “indirect” low-pressure fuel injection to feed the pre-chamber; and extremely high-pressure “direct” injection straight into the combustion chamber. Maserati also added a second “lateral” spark plug to further help fire that reluctant main combustion chamber.
