Jeep’s New Engine Uses F1 Tech to Make Shockingly Big PowerThink of the new 2.0-liter Hurricane 4's secret weapon as something like a mini blowtorch. Turbocharged 2.0-liter inline-four engines practically grow on trees these days. Every major automaker has one, typically making between 240 and 280 horsepower and deployed in a wide range of mass-produced cars, crossovers, and SUVs. Jeep’s corporate overlord Stellantis is no exception, with its soda-sized four-banger powering everything from the Alfa Romeo Giulia to the Jeep Wrangler to the Ram Rampage compact pickup sold in South America. The replacement for that engine, though, is anything but ordinary. Stellantis’s new Hurricane 4 uses a few high-tech tricks—unusual in an engine that will be produced by the hundreds of thousands—to make significantly more power than competitors’ boosted four-cylinders. When it launches in the 2026 Jeep Grand Cherokee later this year (read our First Look here), the new turbo 2.0-liter inline-four will churn out 324 horsepower and 332 lb-ft of torque. That’s a power density of 162 horsepower per liter, 26 percent greater than the Hellcat Redeye supercharged V-8 achieved. Giving the Power to the PeopleThe Hurricane’s healthy power output is made possible in part by turbulent jet ignition, which is employed in Formula 1 engines and the Maserati MC20’s 621-hp twin-turbo V-6. Also called prechamber ignition, TJI adds a small, cup-like combustion chamber inside the main combustion chamber. During the compression stroke, fuel and air are pushed from the primary combustion chamber into this prechamber. A spark plug in the prechamber ignites the gas and jets of fire spray into the main chamber where they ignite the main mixture. “Instead of a spark plug, you’re putting a blowtorch in the chamber,” explains chief engineer Ashish Dubey. The result is extremely fast and complete combustion, which reduces emissions, improves fuel economy, and increases power. Jeep claims the new engine uses 10 percent less fuel to deliver 20 percent more power than the boosted 2.0-liter it replaces. In the refreshed Grand Cherokee, we’re told the Hurricane 4 will be good for 0–60-mph times between 6.0 and 7.0 seconds, a 6,200-pound towing capacity, and up to 23 mpg combined. While the size of the prechamber is nearly identical between the Maserati V-6 and the new inline-four, the hardware has been revised for mass production in Dundee, Michigan, where Stellantis will ultimately crank out 111 engines per hour, and in Kokomo, Indiana, where assembly will begin at a later date. Maserati’s Nettuno V-6 uses a large copper insert, roughly the size of a spark plug, that threads into the cylinder head. The Hurricane four uses a copper chamber the size of a pencil eraser that is press-fit into the head. The difference can be seen in the picture below. Micky Bly, head of global propulsion systems at Stellantis, says the hardware has been consistently reliable during development and that the engineering team has had to focus its efforts on calibrating the advanced combustion system. Each cylinder is fit with two spark plugs, one in the prechamber and one in the main chamber. When the driver demands high torque, only the prechamber spark plug fires. At moderate loads, the prechamber plug fires first followed by the main chamber plug. At idle, low loads, and cold starts, the spark plug in the main chamber leads the prechamber spark plug. A Clean-Sheet DesignWhile the name Hurricane 4 makes the new engine sound like an update of the current GME T4 Hurricane four-cylinder engine, Dubey says only a handful of nuts and bolts carry over along with the 84-millimeter bore and 90-millimeter stroke. The turbocharger, which can cram up to 35 psi of boost into the cylinders, now features variable turbine geometry for quick low-rpm and transient responses and less exhaust restriction on the top end. The torque curve plateaus relatively high in the rev range from 3,000 to 4,500 rpm, but 90 percent of the max 332 pound-feet is available from 2,600 rpm to 5,600 rpm. Power peaks at 6,000 rpm. The Grand Cherokee will run on 87 octane, although the output and fuel economy ratings have been achieved on premium gas. The engine operates at a 12.0:1 compression ratio and runs on the Miller cycle, which closes the intake valve earlier than the traditional Otto cycle for greater efficiency. That change led engineers to adopt an electric intake cam phaser in place of the old engine’s hydraulic adjuster for more precise control. It should enable smoother restarts during stop-start events. The engine incorporates several measures to improve noise, vibration, and harshness as a result of feedback from current owners of Stellantis vehicles. The cylinder walls are thicker (made possible by trading cylinder liners for a super-thin sprayed-on iron coating), the main and connecting-rod bearings are larger, and the crankshaft damper is fluid-filled. Gearing the balance shafts directly to the crankshaft rather than driving them via chain should be quieter, and the addition of port fuel injectors eliminates the noisy clatter of high-pressure direct injection at idle.

MB.EA-M, stessa base come nuova GLC, quindi bev-only, non multienergy. Molto probabile avra guida autonoma level 3 fino a 110km/h.

quelle per la stampa naturalmente, Macroni non lo so ma molto probabile anche. In Germania sono immatricolati YTD09 29 DS8, di quale 28 per Stellantis stesso e 1 per un privato….🤣😝

ANE/Dataforce... 09/25 - 09/24 - YTD25 - YTD24 …Europe...

Ma non avrebbe una certa logica che, per finanziare i 13 miliardi di investimenti aggiuntivi annunciati negli Stati Uniti, fosse necessario risparmiare altrove? E come è possibile risparmiare somme così enormi se non riducendo la gamma di modelli da sviluppare in altre regioni, ad esempio in Europa?

Discussione basata sui articoli Argus/Milanofinanza, non ho capito quale di loro due era la prima.

Futuro della Lancia nel piano Filosa cosi??? ….Lancia, invece, rallenta la propria espansione. La nuova Ypsilon ha avuto un buon riscontro in Italia ma un’accoglienza tiepida all’estero. Per questo motivo i progetti di una berlina e di un crossover sono sospesi. Il marchio dovrà concentrarsi sul rilancio dell’immagine e sulla redditività prima di pensare a nuovi modelli........

La prima. Per ricordare, Alpina come azienda stessa/preparatore non esiste piu. Il marchio ha comprato BMW, quindi in futuro le Alpina made in BMW AG saranno, come gia scritto sopra, una sorta di allestimento super confortevole/pregiosa come le Maybach alla Daimler.

..alta in vista di chi? Una ragazza che compra una Junior perche a lei piace di piu rispetto una Mokka e perche esiste in rosso molto carina?- pensi davvero che e interessata in una hypercar prodotto in 30 esemplari? Nemmeno sa che questa esiste. Azioni come queste sono completamente senza senso.

Esatto…elezione „Auto Motor&Sport Best car 2025“, 95.500 partecipanti, analisi delle categorie per marca, si vede che il disegno e sicuramente l’ultima dei problemi che una Alfa ha in Germania…..

….Ecco - ora abbiamo trovato la vera e unica ragione del declino della FIAT/FGA: i malvagi tedeschi!!! 🤣🤣

…..Questo è già il primo errore di valutazione….. "…..Outro projeto brasileiro da BYD é o motor 1.5 híbrido plug-in flex, desenvolvido em parceria entre equipes do Brasil e da China…." https://quatrorodas.abril.com.br/carros-eletricos/byd-comeca-a-montar-carros-no-brasil-e-estipula-meta-de-600-mil-carros-por-ano/

…qualcuno può spiegare cos’è una motorizzazione bhev ??

Per quale senso?? Per spingwre le vendite di B-Suv a 3 cilindri? Proprio questa confusione impedisce la formazione di un profilo del marchio. Nessuno sa cosa voglia realmente rappresentare Alfa, il DNA del marchio rimane nebuloso e indefinito.

Esatto. Questo segmento per Usa e il segmento centrale e poi - quale cliente reale in Europa (non i wannabe al bar) interessa, che una X5 e prodotto a South Carolina? Nessuno e per il mercato attuale in Usa for make it great again questo fatto e comunque un vantaggio.

…al momento un motore non potrebbe essere EU7 perche la normativa in tutti i piccoli dettagli non e ancora deciso/in vigore finalmente dalla politica.

I ramp up veloci non controllati di Stellantis sono già la prima parte del fallimento.

BMW Group launches demo fleet for diesel replacement fuels22.10.2025 PRESS RELEASE+++ BMW Group demands: HVO100-only vehicles to be included in fleet legislation +++ Proof of alternative fuels in demo fleet now possible +++ Since 2025: BMW diesel ex-works with HVO100 +++ Luxembourg / Munich. The BMW Group is using its presence at the "Fleet Europe Days" on 22 and 23 October in Luxembourg to show fleet operators ways to decarbonise their fleets. In addition to fully electrified vehicles, the focus will be on fuels based on renewable raw materials. Their advantage: the potential to save CO2. With more than 250 million existing vehicles in Europe, their CO2 footprint can be improved if the proportion of renewable fuels is increased. A new technical solution used by the BMW Group is proof that all BMW diesels in a fleet are fuelled exclusively with HVO100. Refuelling data from the vehicle is compared with data from the fleet operator's payment system. This means that the fuel used by the vehicle can be traced seamlessly. An important step towards an "HVO100 only fleet" for fleet customers. Dr. Martin Kaufmann, Head of Powertrain Development at the BMW Group: "Our goal is always to have more environmentally friendly and efficient vehicles on the road. With the diesel replacement fuel HVO100, we have an opportunity to reduce the CO2 footprint of vehicle fleets. Especially in the area of fuels that are not based on fossil fuels, we see a potential that we are ready to realise.” Bernhard Kuhnt, Head of Sales Region Europe, BMW Group: "Fleet customers are extremely important for sales in Europe and at the same time diesel remains a very good powertrain technology for many fleets. The use of HVO100 offers a way to quickly reduce CO2 emissions that takes into account individual use cases - whether driving long distances or towing a trailer - and can thus help our fleet customers reduce their CO2 footprint." Initial contractual agreements with the operators of large BMW diesel fleets in Germany and Italy are imminent. These test fleets, together with the internal BMW Group fleet that has already been launched, will provide important data and findings for the further improvement of the technical solution. HVO100 used in the first fuelling of all diesel produced in Germany Since January 2025, all diesel models produced in Germany are being fuelled with HVO100 before delivery to dealers. This step underlines BMW's commitment to making decarbonisation possible and achievable today. The abbreviation HVO stands for 'Hydrotreated Vegetable Oil' and the suffix '100' indicates that it is filled with 100 per cent pure fuel. "Neste MY Renewable Diesel™" HVO100 is used at the BMW Group plants in Munich, Dingolfing, Regensburg and Leipzig. The fuel from Finnish manufacturer Neste enables a CO2e reduction of up to 90 per cent ("well to wheel") compared to fossil diesel. The initial filling at the plants before delivery to the BMW Group dealer organisation is five to eight litres, depending on the model. For the BMW Group, technological openness is a top priority. "Options instead of bans" is its motto. The company continues to invest in a broad portfolio - from battery electric vehicles, plug-in hybrids and hydrogen fuel cells to highly efficient combustion engines that can run on renewable fuels. The BMW Group has long approved its vehicles for a variety of renewable fuels - including HVO100, B10 and eFuels according to the EN590 standard for diesel engines, and E25 and eFuels according to the EN228 standard for petrol engines. Regulatory framework conditions must catch up Regulation must catch up. To accelerate the uptake of renewable fuels across the market, the BMW Group is calling for an ambitious implementation of the Renewable Energy Directive (RED III), including national quotas that require at least a 30% reduction in greenhouse gas emissions from fuels, to be transposed into national law by 2025. Dr. Thomas Becker, Head of Policy, External Relations and Sustainability at the BMW Group, says: "The BMW Group demands that every measure to reduce CO2 emissions is taken into account at every stage of a vehicle's life cycle. This also includes the use of renewable fuels - especially for vehicles that primarily run on CO2-neutral fuel (CNF). These must be formally recognised in EU fleet legislation. The fuels are available, what we need now is a pragmatic and quickly implementable regulation that enables companies to develop innovations and make them marketable." (BMW Group)

…e se l’accordo Mercosur dovesse effettivamente andare in porto, a medio termine potrebbe essere più conveniente importare il motore anche per i LCV dall'Argentina piuttosto che produrlo a Pratola Sera.

si, ma tutto il mercato di brasile con i suo ca. 2Mio sta per circa 2,5% del mercato globale, quindi non di grande importanza.

si ma con quale volume ridicolo - e i cinesi stanno appena iniziando ad attaccare il Sud America.

Non necessariamente: come è consuetudine oggi nel mondo finanziario e delle grandi aziende, si separa la parte più produttiva dal resto meno produttivo per rendere la prima più attraente in borsa. Secondo questa logica, si potrebbe quotare in borsa la parte redditizia statunitense e lasciare che i due morti a piedi, Fiat e Peugeot, continuino a operare insieme in Europa.

…ma dal 2028 in quale modelli userano questo motore? Solo Ducato&fratelli oppure anche per auto?

..almeno crea utili questa strategia….. (CNBC)

…………… Secondo Tavares, Stellantis sta attraversando una fase complessa segnata da un calo della domanda nei mercati occidentali, dalla crescente pressione dei costruttori cinesi e da tensioni geopolitiche che condizionano le strategie industriali dei grandi gruppi automobilistici............ ...........Tra i vari scenari prospettati, Tavares non ha escluso la possibilità di una scissione tra le divisioni europee e statunitensi del gruppo. In tale scenario, Stellantis potrebbe decidere di ridefinire la propria presenza globale seguendo logiche di mercato più mirate. Ad esempio, le attività americane (quindi Chrysler, Ram, Jeepe Dodge) tornerebbero a concentrarsi sul Nord America, mentre le operazioni europee marchi come Fiat, Alfa Romeo, Lancia e Maserati potrebbero finire sotto il controllo di un costruttore cinese, interessato a rafforzare la propria presenza nel Vecchio Continente. Una strategia che ricorderebbe, almeno in parte, quella intrapresa da General Motors negli ultimi anni, con un progressivo disimpegno dai mercati meno redditizi………..
