Il bello di viaggiare senza pensieri promozioni. Se fai il tagliando di manutenzione ricevi 1 anno di assistenza stradale gratuita. That’s one of the reasons behind Subaru’s highly competitive fuel economy numbers even with all-wheel-drive (AWD) drivetrains. Rinnova la tua serenità alla guida con SUBARU SAFE +1: protezione di anno in anno fino al raggiungimento dellottavo anno di copertura. Boxer engines also improve safety as they are more likely to drop below the passenger compartment rather than into it during a frontal collision.īetter fuel economy: Thanks to the flat layout of boxer engines, the flow of power from the engine to the transmission is more linear, reducing the need for extra components and increasing efficiency. La piccola compatta nipponica a motore e trazione anteriori segna linizio di una filosofia costruttiva che oggi domina tutta la produzione Subaru. As a result, these cars have better handling and experience less body roll. ll 14 maggio 1966 veniva lanciata sul mercato la Subaru 1000, primo modello dellazienda giapponese con motore boxer. It has been produced since 2004 for the Impreza WRX STi sport car which, in the various competition versions, achieved many successes in the international rally championships. The boxer engine EJ257 is one of the most powerful versions of the Subaru EJ family. Lower center of gravity: By virtue of being flatter, boxer engines have lower centers of gravity than other engines, which lowers the center of gravity of the cars in which they are mounted. Motore Subaru Boxer EJ257 - 2.5 Turbo 2004 - 2012 Tweet Description. This makes them much flatter than V or inline engines but also wider. Less vibration: Because boxer engines have pairs of pistons reaching dead center simultaneously in opposite directions, they inherently produce less vibration than traditional inline or V engines, which require additional parts to achieve the same effect. Dopo l’introduzione dell’ibrido e-boxer sulla Forester, la Subaru ha inserito nella gamma della XV lo stesso 2.0 elettrificato da 150 CV e 194 Nm, proponendolo come unica alternativa all1.6. Boxer engines, also known as flat engines, have the cylinders laying side-by-side in a horizontal arrangement. Low vibrations have made boxer engines popular in light aircraft… Generally, flat engines with four or fewer cylinders-like the 2.0-liter that powers the Subaru BRZ and Toyota 86-are referred as boxer engines while flat engines with six or more cylinders are simply called flat-six engines, flat-eight engines, and so on. However, people may not always match the terminology to that strict guideline. The difference between a flat engine and a true boxer engine can be boiled down to the following: boxers use one crankpin per cylinder while flat engines use one crankpin per two horizontally-opposed cylinders. They were first invented in 1896 by Karl Benz and were quickly nicknamed “boxer” engines because each pair of pistons moves in and out together like the gloves of a boxer. In Porsche’s case, though, those engines aren’t flat-fours, and instead, they have six-cylinders. Some of the most popular Porsche models already use boxer engines, including the Porsche 911. Another automaker that uses boxer engines is Porsche. Unlike V engines, flat engines have horizontally-opposed pistons, which makes them wider than traditional engines but more naturally balanced. Toyota, which collaborates with Subaru often, uses a boxer engine in the Toyota 86, for example. These advantages are evidence of the vision that Subaru has in using the Horizontally-Opposed Engine.The 2017 Subaru BRZ uses a four-cylinder boxer engine to make 205 horsepower and get 33 mpg hwyįor the most part, the term “boxer engine” is used to refer to flat engines. A prodigious 350-Nm of peak torque is delivered at a lower 1,600 rpm – providing smooth, free-breathing performance at any speed. And whilst meeting the ultra-clean EURO5 emission standards, the engine delivers even more torque compared to previous models. Ceramic glow plugs also quicken starting in cold weather. The result is a more compact combustion chamber and greater fuel efficiency, and combined with a higher pressure common rail fuel injection, an improved oxidizing catalyst with closed Diesel Particulate Filter (DPF), a variable nozzle turbo and electric power steering, these all help to reduce fuel consumption and CO2 emissions. With pistons moving horizontally, the SUBARU BOXER engine has a flat, low profile, almost perfectly symmetrical, for a well-balanced. The SUBARU BOXER, however, was originally designed with rigidity in mind, allowing the 92.0 mm x 75.0 mm bore and stroke of the 2.0-litre petrol four-cylinder engine to be changed to a square 86.0 mm x 86.0 mm design. When petrol engines are converted to diesel, strengthening of the engine block usually makes the engine bigger and heavier. The world's first commercial Horizontally-Opposed Diesel Engine developed for passenger vehicles is the SUBARU BOXER DIESEL.
