Why are Subaru engines so noisy?
The noise is caused by the timing chain and tensioner.” We reached out to Subaru of America to see if they could (would) explain the unique sound quality of the engines, so many of us know and love.
The release of the high-pressure combustion gasses entering the exhaust system causes this noise..
What is the difference between a boxer and a flat engine?
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.

What cars have flat 6 engines?
The most notable use of flat-six engines is the Porsche 911 sports car, which has used flat-six engines continuously since 1963. Several other car manufacturers, including Subaru, have produced flat-six engines at times. Flat-six engines have also occasionally been used in aircraft and motorcycles.
Is a boxer engine a flat 4?
The most common type of flat-four engine is the boxer-four engine, each pair of opposed cylinders moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however the two cylinder heads means the design is more expensive to produce than an inline-four engine.
Are Subaru engines made by Porsche?
Subaru celebrates 50 year of continually using the boxer engine. … They use it in the Forester, Outback, Crosstrek, Impreza, WRX/STI, Legacy and BRZ. Porsche is the only other automaker that uses the flat, H-shaped, opposed-piston “boxer” engine. It’s a good design and it’s winning awards.
Which Subaru engines to avoid?
Subaru 2.5-L Turbo Four Cylinder Owners of 2009-14 Subaru Impreza WRX and WRX STI models have launched a class-action lawsuit, alleging the pistons and PCV (positive crankcase ventilation) systems in the high-performance 2.5-L turbocharged engines may overheat or malfunction, requiring a king’s ransom in repairs.
Why does Porsche use flat engines?
The ideal choice for sports cars This lowers the centre of gravity, allowing for a sportier and more dynamic style of driving – and not just when cornering. If the flat engine is installed at the rear as in Porsche vehicles, traction is improved because the weight of the engine rests on the drive axle.
Do Subarus have engine problems?
The most recent recall that Subaru has put into place for its engine issues was in April of 2020. 188,000 vehicles were recalled over risk of the engine stalling. This covered the 2019 Subaru Ascent, the Subaru Impreza, the Subaru Legacy, and the Subaru Outback. the problem related to a faulty fuel-pump.
Why are V engines better?
V engines, on the other hand, prioritize power and space. Because of the way they merge, V-shaped engines can fit more pistons into a smaller space, produce more torque at lower RPMs, and generally have greater engine displacement.
Does any car have a v4 engine?
There’s really only a few companies that produced V4 engines in any sort of appreciable, mass-market quantity: Lancia (they liked these, and used them in a bunch of models), Ford of Britain (the Essex V4), Ford of Germany (the Taunus V4, also used by Saab, which made that brand fairly famous for such motors), AMC (only …
Are boxer engines reliable?
Due to the low, wide mount, the boxer engine can prove difficult to service. Even changing spark plugs can be a substantial job. However, boxer engines are known for their reliability, and should require less service than most other engine types.
How does a flat 4 engine work?
In the flat-4 engine, the pistons point opposite of each other, which means the forces balance out. This is why a flat-4 is smoother than an inline-4; the inline-4 engine has no way to balance the forces out, which causes vibrations and less balance.
What is an H 4 engine?
Subaru has marketed its flat-four and flat-six engines as “H4” and “H6” and “H8” respectively. The letter “H” in this case refers to “horizontally-opposed”, an alternative term for flat engines; these engines can also be said to look like a “H” or conjoined “H”s, albeit from the top and in schematic form.
Do Subaru engines last long?
Subaru is very different from other car brands in that they are very reliable and last forever. It is not unusual to see a Subaru that is 15+ years old with well over 200,000 miles and still running strong. … They do easily last this long IF you take care of the car, oil changes, timing belt, etc.
What cars have flat 4 engines?
Subaru have been producing cars with a front-engine, four-wheel-drive layout powered by flat engines (mostly boxer-four engines) since 1971. Examples include the Subaru Leone (1971-1994), Subaru Legacy (1989-present) and Subaru Impreza (1992-present).
Is straight 6 better than v6?
An inline six is actually more refined than a V6 with the same displacement. In fact, improvements in refinement were one of the main reasons why Jaguar Land Rover decided to switch back to inline sixes (an engine configuration the company had abandoned decades ago in favour of V6s).
Why are boxer engines bad?
On one hand, the boxer engines provide an unmatched performance to a sports car. However, the wide configuration makes it a bit hard to work on these mechanically. Besides, the obstruction of airflow they create in the engine area might even lead to their failure at high speeds.
Does Subaru make a flat 6?
3.6-liter Flat-6 The largest SUBARU BOXER engine available, this 3.6-liter 6-cylinder serves up 256 horsepower and 247 lb. -ft. of torque.
What is the best Porsche engine?
1) M97/74 – Porsche 997 GT3 RS 4.0 This water-cooled wonder pushed the limits of the modern flat six; the Porsche 911 can barely take an engine larger than 4.0 litres. Torquey yet still with the wonderful GT3 RS peak, this engine has it all. We wonder if Zuffenhausen will ever beat it.
Is Boxer engine better than inline?
Boxer engines derive several performance advantages inherent to their design, since the center of gravity on an opposed engine is much lower to the ground compared to an in-line or V design. This allows for better lateral acceleration. In addition, the benefits to handling are enormous.
