Why are v8s so inefficient?

Why are v8s so inefficient

Restricted port design means restricted flow, and that translates to less power, especially at high rpm, when the engine is trying to flow large amounts of air and fuel through the engine. High torque at high rpm is where big horsepower numbers are made, and high flow is necessary for high torque at high rpm.

Are V8 engines more reliable?

Some of the world’s most popular V8 engine might just be more reliable than you would think. You have heard of V8s. You might have even seen some up close. But even if you are not familiar with how they work, every gear head knows that V8s equal power.

What is a V8 engine?

The V8 engine with a cross-plane crankshaft is a common configuration for large automobile engines. The displacement of modern V8 engines is typically between 3.5 to 6.4 L (214 to 391 cu in), though larger and smaller examples have been produced, such as the 8.2 L (500 cu in) V8 engine used in the 1971–1978 Cadillac Eldorado .

Why do V8 engines Rumble?

The iconic rumbling exhaust sound produced by a typical cross-plane V8 engine is partly due to the uneven firing order within each of the two banks of four cylinders. A typical firing order of L-R-L-L-R-L-R-R (or R-L-R-R-L-R-L-L) results in uneven intake and exhaust pulse spacing for each bank.

What angle does a V8 engine use?

The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a larger width than V8 engines that use a smaller V-angle.

What is the worst V8 engine ever made?

While these cars are all underpowered, none come close to the Triumph V8, unleashed in the 1977 Stag. This engine is widely acclaimed as the worst V8 ever made, though of course if every part is replaced every 30,000 miles then any engine could be great.

Are V-8s getting rarer?

V-8s are getting rarer, but there are still plenty of great coupes and sedans with eight-cylinder power. The venerable V-8 engine is a dying breed as fuel economy and emissions regulations push automakers to downsize and electrify powertrains.

Is the V8 the future of cars?

The V8 engine has been available for cars for over 100 years, but we may be saying goodbye to them very soon. In a push to lessen the impact on the environment, most countries are looking to do away with gas-powered cars in general, shifting to electric-powered transportation.
