Why V8 over V12?

The thermal efficiency of V8 engines is between 29% to 40%. In contrast, the thermal efficiency of a V12 engine can be 50%. However, the maximum brake power capacity of the V12 engine is 19,300 hp, and the V8 engine is 10,000 hp. The engine compression ratio of the V12 engine is 9.5:1, and the V8 engine is 13.7: 1.

Is a V8 engine better than a V12?

In general, V8 engines tend to be more fuel-efficient than V12 engines, due to their smaller size and fewer cylinders. The V12 engine has more cylinders and therefore has to work harder to produce the same amount of power as a V8 engine, which results in higher fuel consumption.

Why don't they make V12 cars anymore?

Environmental Protection

No need for a V12 here. Since 1970 the EPA has set increasing emissions standards, resulting in new US cars spewing out approximately 99 percent less common pollutants.

Why are V12 engines not used?

In cars, V12 engines are not common because of their complexity and cost. They are normally found only in high-end sports cars and luxury cars. For these cars, they are desired for their power, low vibration, and distinctive sound. Before World War II, V12 engines were found in many luxury cars.

What's the point of a V12 engine?

V12 Engines

Smooth Power Delivery: The V12 has a piston firing every 60 degrees of crankshaft rotation, giving it one of the smoothest power deliveries of any engine. Free Revving: Because the engine is naturally balanced, the crankshaft can be made with minimal counterweight, reducing rotational inertia.

Engine Layouts - Explained (V6, I6, V8, W12)

What are the disadvantages of V12?

Balance and smoothness

The drawbacks of V12 engines include extra cost, complexity, friction losses, and external size and weight, compared with engines containing fewer cylinders.

How much HP is a V12?

A V12 engine is a type of car engine with twelve cylinders. This means that it has more than six cylinders and therefore more than 1200 horsepower. 1. A V12 engine produces 690 horsepower and has a top speed of 200mph.

Are V12 more efficient than V8?

The thermal efficiency of V8 engines is between 29% to 40%. In contrast, the thermal efficiency of a V12 engine can be 50%.

Why are some V8 faster than V12?

A V8 engine is generally faster than a V12 engine for a few reasons. Firstly, a V8 engine is typically smaller and lighter than a V12 engine, which means it is less cumbersome and has a lower center of gravity. This can give the car an advantage in handling and acceleration.

Why is V10 banned in F1?

First of all, FIA, the governing body, decided at one point, that 3.0L V10 engines were too strong and wasteful, so they decided to reduce them to 2.4 V8. Those engines were no joke, even at very start, Cosworth claimed theirs can rev above 20.000 RPM.

Which car has V16 engine?

The Cadillac V16 engine is a term that applies to two different Cadillac-designed V-16 automobile engines, an overhead valve 45-degree 452 cu in (7.4 L) model produced between 1930 and 1937, and a 135-degree side valve 431 cu in (7.1 L) between 1938 and 1940.

Are there any American cars with a V12?

Falconer LS V12

In 1990, Falconer introduced its own V12 to the market. The engine is based on the venerable small-block Chevrolet V8, but with a brand-new casting featuring 12 cylinders instead of eight. It retains a 90-degree V angle instead of the 60-degree vee angle used by most V12s.

Why is a v8 so powerful?

Advantages of a V8 engine

The power of eight cylinders allows for heavier hauls and higher towing capacity. More power also means quicker acceleration and speed. If you prefer a performance vehicle with more power, endurance, and an exceptional feeling off-road, the V8 engine is a great fit.

Why is a v8 more powerful?

V-8 cylinders tend to have more of a perpendicular angle within the engine. V-8 engines have more power, which results in a higher power ceiling than a V-6. A vehicle with a V-8 can be more beneficial for fulfilling worksite needs.

Why are v8s louder than v12s?

Because both the V-10 and V-12 have a firing order (by right left) of R, L, R, L, R, L, etc. But because a V-8 uses a 90 degree crankshaft, the firing order is R, L, R, R, L, R, L, L- which makes the distinct sound only a V-8 makes.

Why old V8s was so underpowered?

The change to unleaded gasoline required lower compression. Lower compression means less power. Emission and pollution controls also reduced horsepower.

What is the most powerful V8 engine ever?

What is the most powerful engine for a car?

Why do v8s sound better?

Because they have twice the cylinder count, a V8 engine's frequency is in a higher and generally more pleasing acoustic range.

Can a V12 have twin turbo?

There haven't been many V12 SUVs. The Rolls-Royce Cullinan, which uses the same mega-smooth 6.75-litre twin-turbo V12 as every other Rolls, is the only one on this list. A controversial car to say the least, but very well executed. Click here to read our review of the Rolls-Royce Cullinan.

Is a V12 street legal?

Joining the now sprawling list of track-only hypercars is the new De Tomaso P900. Based on the P72 road-going retro-styled supercar, the P900 gets a 900PS V12 along with a dusting of aero frippery.

What is the most powerful V12 ever?
