    Pure Pleasure: Highly Efficient 1.4-Liter Turbo in the New Astra

    Opel Media Online
    2015-06-17

    - All-aluminum: four-cylinder gasoline unit of the latest engine generation
    - Instant throttle response: Dynamic response and ample performance
    - Pure high-tech: Direct fuel injection and turbocharging for highest efficiency
    - Milestone: Eight millionth engine from Szentgotthárd a 1.4-liter turbo





    Rüsselsheim. The full name of the new Opel engine is 1.4 ECOTEC Direct Injection Turbo and it will celebrate its world premiere in the new Opel Astra at the International Motor Show in Frankfurt (IAA) in September. The four-cylinder turbocharged unit with central direct fuel injection will be available in two outputs, 92 kW/125 hp and 110 kW/150 hp. This combination links the new all-aluminum engine to the recently introduced 1.0 ECOTEC Direct Injection Turbo known from Opel ADAM and Corsa. In fact, the new 1.4-liter four-cylinder engine is the big brother of the one-liter, three-cylinder unit that has been praised by the trade press since its introduction in the ADAM ROCKS and the new Corsa generation. Both engines are members of the so-called small gasoline engine family – a group of high-tech engines with three or four cylinders and a displacement below 1.6 liters. They are key players in the biggest engine offensive in Opel’s history which will see 17 new engines brought to market from 2014 to 2018.

    Best in class: The new Opel four-cylinder engine purrs like a kitten

    A lot of attention was paid to dynamic responsiveness and high performance while curbing fuel consumption during the development phase of the 1.4-liter turbo. The engine delivers maximum torque of up to 245 Nm very early. The maximum power is available between 2,000 and 3,500 rpm – an outstanding torque plateau. Perfect conditions for driving pleasure in combination with efficiency. According to preliminary data, the powerful turbo with Start/Stop will consume a mere 4.9 liters of gasoline per 100 kilometers in the combined cycle (114 g/km CO2). The 1.4-liter turbo will therefore be able to outperform even two-liter gasoline engines in all performance characteristics and replace them. The engineers once again paid close attention to low noise levels and vibration behavior during the development of the 1.4-liter turbo – just like they did for the one-liter, three-cylinder unit. The engine block was constructed with resonance reduction in mind, the oil pan split into two, the integration of the cylinder head into the exhaust manifold is noise protected, a sound absorbing cam cover has been designed, the high-pressure injection valves decoupled and the timing chain trimmed for quiet concentricity.

    “Our new turbocharged 1.4-liter, four-cylinder engine with central direct injection is part of the newly designer small gasoline engine family and embodies its attributes ‘powerful, efficient and cultivated’. The all-aluminum unit is not only environmentally friendly but also sets new standards in driving comfort,” said Christian Müller, VP GM Powertrain Engineering Europe.

    The lightness of being: The new degree of efficiency

    Based on its construction, the new 1.4 ECOTEC Direct Injection Turbo adds less weight to the car. The aluminum engine block alone weighs ten kilograms less than the cast-iron block of the current 1.4-liter turbo, making it the perfect match for the new, highly efficient Opel Astra. Apropos efficiency, this is where the 1.4 turbo can really show its technical advantages: to make the engine as light as possible, the crankshaft is hollow cast, the oil pump drive is especially low friction and the oil pump works in two pressure levels accordingly. The entire engine is designed for low friction oils with a viscosity grade of 5W-30. All of these measures ensure fuel efficiency of the highest standard.

    While the three-cylinder Opel units are typical representatives of engine downsizing (smaller, lighter, more efficient), the Opel engineers speak of “rightsizing“, i.e. the perfect balance between low load and high load efficiency, when talking about the new 1.4-liter four-cylinder engine.

    Milestone engine from Szentgotthárd

    The 1.4 ECOTEC Direct Injection Turbo is manufactured in the Opel Flex Plant in Szentgotthárd. And it is already responsible for setting a new milestone for the Hungarian plant. The eight millionth engine from Szentgotthárd left the production line today and it was, of course, an all-aluminum, four-cylinder unit that will make its debut in the new Opel Astra from September.

    “We have world class flexible engine plant in Hungary and it plays a key role in our product strategy. Congratulations and a huge thanks to the entire team here – eight million engines is something to be very proud of and I am sure that we will be able to celebrate even more milestones here in the future,” said Peter Christian Küspert, Vice President Sales & Aftersales Opel Group, who attended the celebrations along with Marc Schiff, Executive Director Manufacturing Opel/Vauxhall Europe, members of the Hungarian government and local officials.

    For those wondering, 245 Nm torque = 181 Lb. Ft.

    That's an increase of 12 horsepower and 33 Lb. Ft. versus the 1.4 turbo in the current Cruze. I wonder if the new Cruze will feature this DI aluminum mill.

    This will probably power the Cruze in the US. I wish they would push it to at least 200 HP.

    Pure Pleasure? Where's the pleasure? In the gas savings, I guess?

    I like how the performance is labeled as "ample".

    VS the 1.0L "little brother" and a market stuffed with low powered C segment hatches 150 BHP IS powerful

    Same engine as in the Chevy Sonic, no?

    The Sonic Turbo has 138hp and 138lb/ft of torque...what wouldn't be pleasurable about this engine in the Sonic? 45 more ponies sounds awesome to me. Maybe GM will do an even better Sonic RS to compete with the Ford Focus ST.

    We can at least hope...

    Compared to the driving dynamics and NVH of the 1.3 CDTI (95hp/210Nm), the new 1.4 is pure pleasure.

    The SGE family has been slow to make it to these shores. I think the only uses so far are the 2016 Volt and base Malibu. I'm sure next gen of the others (Cruze, Sonic, Equinox...) will all show up with a version.

    No - the Sonic uses the old Family 0 LUV engine, 138 hp / 138 lbft, with cast-iron block - this is an all-new version of the Small Gasoline Engine (SGE), 150 hp / 181 lbft, aluminium block

    HOW many USDM cars have bean designed AFTER the SGE was well enough along? Opel designing the SGE would allow them more "access" the the SGE program and even then how wide spread is SGE in Opel? NOW

    the SGE would I assume be in the NEXT GEN sonic/aveo/"carl" that was spy shown in Korea a month ago I assume at least in USDM trim

    Definitely true. With so many MCEs instead of full redesign we're waiting for next gen on many models for SGE implementation.

    I believe DI is standard on all SGE variants, so yes the Cruze will come with DI. (Bring on the tuners!)
