One of the most technically advanced four-cylinder engines ever just launched. A small, two-liter inline-four is cranking out 324 horsepower, but it’s not just the power that’s impressive, as it’s thermal efficiency can rival that of a Toyota Prius engine. The secret? Turbulent Jet Ignition - the same technology used in Formula 1. A tiny pre-chamber surrounds the spark plug, which when it fires, shoots out flames from the pre-chamber, igniting the air-fuel mixture rapidly, reducing the likelihood of knock, and efficiently producing power. Compare this to traditional engines, where the flame propagation is much slower. This rapid combustion is combined with a variable geometry turbocharger, rare for gasoline engines, that supplies up to 35 PSI of boost pressure, resulting in a highly potent engine, that sips fuel politely.

This is going to be Stellantis's most technologically-advanced oil leak to date
35 PSI in a stalantis design? Uh oh
Sounded good until you mentioned Jeep
And it’s stalantis so you know it’s gonna live in the shop
When I see a small engine make such power, I'm impressed at how far engineering has come, but I also have to wonder how long such engines last, as this must put a lot of stress on its parts no?
Power and technically advance means nothing if it's not reliable.
Turbos and Stalantis. Yeah... Moving on.
I mean, the Corolla GR puts out 300 hp from a 1.6...
And it’ll run for a staggering 60K miles before blowing up!
My miata is giggling in the garage.
The technology in this is amazing, but I can’t say that the best work from the minds at Chrysler, Fiat, Peugeot, and Citroën has left me very confident that this won’t end up completely grenading itself are those high boost pressures.
I can only think of how it will peform over 100k
Great! Advances in pressure. Any advances in metallurgy to handle it?
do they know how much a head gasket replacement is going to cost their customers?
Translation: this engine will grenade itself after 200000km and will be prohibitedly expensive to repair. Also my european mind cannot comprehend calling a 2l engine "small".
One of the most technically advanced bombs ever made by stellantis.
And then they will ruin it by running the belt in oil?
You lost me when it was compared to the Prius. So does it get at 50 mpg?
Took them 50 years to catch up to cvcc😂
Great to signs of life at Stagnantis
