    The all-new, direct-injected, twin-scroll turbo-ed, multiair2-ed 2litre petrol I4 engine for the ALfa Romeo Giulia (initially: will be used on all Alfa-s, and a cheaper version on future Dodges and perhaps Chryslers in the usa, the Dodges will of course be twinned to the Giulia&co, and perhaps even made-in-italy alongside them by 2018?).

    The Giulia 2litre turbo 276hp, and of course the QV engined one too, has notably more bhp-per- and torque-per-tonne/kg of any car of its class (Merc c-class+amg avatar thereof, BMW 3 series+M...)

    Clearly a class-best petrol engine, by a distance (esp relative to its capacity), as is the twin-turbo 510 hp Ferrari-deived one used on the Giulia QV and on Maserati-s including the new Levante.

    Alfa Romeo presented a summary of their 2.2 L diesel engine for the new Alfa Romeo Giulia [E. Bonamassa]. This is the first all-aluminum engine for FCA and comes in two ratings; 132 kW/450 Nm and 155 kW/470 Nm. The cast iron block engine it replaces was rated at 147 kW and 440 Nm. The aluminum block is produced with a low-pressure die-cast process developed by FCA subsidiary Teksid and yields an engine 30 kg lighter than the cast iron version. The single Honeywell VNT turbocharger is integrated into an insulated exhaust manifold, has a ball bearing cartridge, water cooled center housing and for the 155 kW engine, comes with a turbocharger speed sensor to allow maximizing boost pressure while avoiding over-speeding during transients and high altitude. A dual loop EGR system ensures sufficient EGR flow at all operating conditions. The aftertreatment system consists of a NOx adsorber and DPF. For RDE, a urea SCR catalyst will be incorporated.

    SCRs are the future and clean diesel will have it's uses for many more years.

    Ford has already started giving it in their latest pickup trucks. Others should follow too.

    why didn't they develop 1,2 tjet? Besides benefiting in India for excise duty benefit it can also be used in entry level hatchbacks worldover in different power versions.
    Also FIRE engines can be phased out.

    They already have begun the phaseout process of the Fire engines in Brazil, though not of the 1.4 t-jet multiair, which is very fine and still very competitive, though it too is due for gradual replacement in a few years in europe+latam, though likely not india?

    The Fire replacement engine family is known as the gse (global small engines): like the new and cutting-edge gme 2 litre turbopetrols mentioned for the Alfa Giulia (and set for Jeep and Dodge too), they will also be modular, will be all-aluminium, designed to be light, varying from an 80 hp 1.0 litre 3 cylinder to a 1.4 i4 + its turbo-ed version , eventually. These 3 cylinder gse is being deployed in the brazilian market right now. The i4 one will debut on the 2017 new Punto +new grand Sienna there. these engines are specifically designed for very good low end torque and a wide power band (rather than outright hp): even the non-turbo-ed versions. And for better-than-Fire emissions and overall weight+compactness.

    It remains to be seen if they bring these engines for localization on the new Punto etc that may (or may not! who knows yet?) launch in india in 2018/19, or whether instead they continue to use the 1.2 fire and the t-jet, perhaps with multiair this time?

    cheers

    An engine that is being hailed as 'one of the greats' and a unqiuely superior 'all-time-best' engine when considering turbocharging: turbocharged and yet zero 'lag', excellent real-world emissions and fuel efficiency for its size and class, and yet.....very high revving, with a very wide powerband and a strong topend (unlike most turbo-ed vehicles, and like all the NA v6 and v8 engines historically that Ferrari, Maserati, Alfa Romeo and Lancia are so famous for.

    @asimpleson

    FCA's new petrol (very definitely) and new diesel (less so) engines are like this one clearly bleeding-edge and respective class-leading, all parameters considered. With the new Alfa Giulia showcasing them all, especially the Ferrari-associated 510hp twinturbo v6 on the QV version of this car, and the new (more for usa, japan and china) 2 litre turbopetrol multiair which will come in tunes of 200odd hp and 280odd hp, with similar attributes to this highend ferrari engine: nearly no lag, direct injection, class leading emissions, refinement and efficiency (thanks to multiair electronic vvt and variable valvelift etc etc)

    (please use Google translate)

    The phase out of the FIRE family of small petrol engines is underway, first with the new UNO coming soon, and then to be deployed in 2017 on the 'new Punto' and 'new grand Sienna' (project namesx3h and x3s): in Brazil. Europe follows for the entry level petrol offerings on the 500 and the Panda.

    This is a very lightweight, very compact all-aluminium engine designed for greater lowend torque and a hefty torque upto no-more than 3500-4000 rpm, so as to enable fuel efficiency and responsiveness in traffic. Hence, it has 3x2=6valves. The new Punto etc will recieve the 1.3x=1.4 version also with 2 valves per cylinder+light weighting etc (around 100bhp, around 140Nm at lower rpms than the current FIRE 1.4 and than the benchmark, low-cost NA engines like the Toyota 1.5 petrol).

    Eventually of course there will be 12valve versions of the 1 litre engine (likely turbocharged) and also the t-jet multiair one will also be replaced by a turbo4 16v version of this same Fire-replacing new engine family ('GSE': Global Small Engine family.)

    These all-aluminium, low emissions+high-efficiency engines have a modularized design, enabling large-sharing across these different configurations.

    It will be interesting to see whether they deploy the gse engines, locally made or at least assembled, in India when (and IF) FIAT launches its all-new models ('new Avventura/Punto...') They may not need to, since it is possible that the taxation disadvantages of the 1.4 Fire esp in turbo-ed configurations (t-jet) will be gone due to the GST?

    The Alfa Romeo Giulia with the 2 litre turbopetrol, with DI and multiair etc, will also get a 350hp, even-higher torque version, since it will apparently deploy an 'e-supercharger', that is based on a 48volt electrical system that gives about 30% higher turboboost instantaneously (no lag whatsoever, since it is electrically powered to very quickly spin at 75000 rpm or beyond.) With little if any cost to efficiency.

    The Giulia with the 350 bhp gme engine has been homolagated in europe and the usa, and will likely first appear when the Giulia launches in the usa.

    Most likely the supplier is VALEO, who'd extensively tested the development and demonstration editions of this e-supercharger on an Alfa Romeo Giulietta QV 1.75 tbi a few years ago.

    Meanwhile in Brazil the drastically facelifted Uno is launching right now: with the new 1litre (80 bhp, 100Nm) 3-cylinder all-aluminium Global Small Engine. 2 valves per cylinder for better low end torque. MUCH lighter and more compact than the 1.2 Fire it replaces, too.

    Next up will be the 1.3x litre GSE 8 valves (100 bhp, 140 Nm) that will be the entry level engine on the New Punto and new Grand Sienna (for 2017).

    Turbocharged versions of both the 3cylinder (12v) and the 4cylinder (16v) will be deployed in 2018 onwards, as much in europe as in brazil.

    The Fire and t-jet engine family will start their retirement now. Though the t-jet esp in multiair form, indeed even the Fire 1.4 Multiair with 105 bhp are still excellent, even in europe for many applications, and in India? I suspect India will continue on the mjd + t-jet-version-of-FIRE path, both on the Jeeps (2017 onwards) and the next-gen Fiats (2018 onwards).

    From Brazilian median:
    Tudo sobre o novo motor da Fiat que estreia no Uno - Motor Show
    Google translate:
    This new family will consist of 1.0 3-cylinder engines, as they do here Volkswagen, Hyundai, Nissan, Ford, Peugeot and Citroen (check here more details on the technical advantages of tricilíndricos thrusters). Furthermore, there is a 4-cylinder version and 1.332 cm³, using exactly the same technology as the cylinder 3 and the same components. That is, it is the same motor 3 cylinders, only one cylinder more. On an industrial scale, a tremendous savings, because we have two different engines that share its main parts.

    Let the numbers: the new GSE family will have a single command overhead valves with phase variator. There will be two valves per cylinder, as engineers more longed torque than the maximum power. Crankshaft will lag a few degrees between the handles, so as to reduce friction rolling and better enjoy the burning of fuel in the chambers generating a greater impetus to the crankshaft.

    Moreover, in some operating conditions, such as low load on the accelerator and constant speed or when the driver is not requiring torque or power and the motor is being used only to keep medium and moderate speeds, the engine runs almost in Miller Cycle , technology hitherto used in the propellants of hybrids: the electronic system reaches delay valve control up to 40 degrees for recirculating part of exhaust gases and thus the polluting emissions dramatically decreases and the fuel consumption reaches improve almost 7%. An innovative technology.

    The connecting rods are long and light, the compounds pistons of an alloy of aluminum and graphite to reduce friction and the nominal compression ratio is in the region of 13: 1. Of course all of them as much as 1.0 1.3, will flex and benefit from the high compression ratio which will improve the performance, giving strength at low revs, as will a low fuel consumption by improving the thermal efficiency of the machine.

    Preliminary figures are: 77 hp with a torque of 1.0 11kgfm for three cylinders, when fueled with ethanol while 1.3 4-cylinder engine will produce 106 horsepower and a maximum torque around the 14,7kgfm. If the power is not impressive, it's the torque that this new family that will produce more brilliant results to acelerador.Os pedal command torcudos new engines will be, as they say in the jargon of cars.

    A little bird told me too that are already planned turbocharged versions of these new engines. As in this case the goal is performance, these new turbo thrusters have heads 4 valves per cylinder and replace larger engines now in production. Just so you have an idea, these new engines have about 120 hp, 3-cylinder in version 1.0, and between 150 and 160 hp in version 1.3.

    They could be safely used in larger Fiat cars and even Jeep. The new engines will initially be launched in the new Uno after the 3-cylinder will move to the Mobi and gradually replace the older engines of all Fiat line. These new drivers, fruit of a work Brazil- Italy, guided whole new range of engines that are to be born throughout the Fiat group.


    --------------

    Apparently these engines will often run on the Miller (rather than otto) cycle, also making them extremely pair-able despite their small size, with batteries for full-hybrid-yet-good-performance applications (in the not-too-distant future when battery prices are low enough.)
