How much HP can a V12 have?
Large V12 diesel engines are common modern cruise ships, which may have up to six such engines. An example of a currently produced V12 marine engine is the Wärtsilä 46F engine, where the V12 version has a displacement of 1,157 L (70,604 cu in) and a power output of 14,400 kW (19,300 hp).
Can a V8 beat a V12?
A V8 engine is not ‘faster’ than a V12 engine. The engine has no speed; the vehicle in which it is placed determines the speed. What speed a vehicle is depends on a number of factors, including its aerodynamics, weight, engine power, etc.
How fast can a car with a V12 engine go?
A 7.3L V12 engine makes 678-horsepower and 575 lb-ft of torque allowing the car to reach a top speed of 217mph. it glides from 0 to 60mph in 3.3 seconds flat and achieves the quarter-mile drag time in 9.94 seconds.
Why are V12 engines not used?
Why don’t we use v12 engines in race cars if they produce so much horsepower? They are more complicated and have more parts to fail than fewer cylinders with the same displacement. There is no need for a super smooth engine in racing.
Are V12 engines efficient?
In addition to that six cylinders in a row can be balanced perfectly, better than 4 cylinders in a row. That is the reason that many luxury sedans rely on V12 engines – they run significantly smoother than V8 engines. On the other hand a V8 engine is simpler, lighter and has a better efficiency (less moving parts).
Why do luxury cars use V12?
More cylinders are preferred for two reasons: more cylinders can be used to create more power, and more cylinders (especially in sixes) make the engine more balanced (less vibration). So V12s are used to fit in 12 cylinders, which produce a lot of power smoothly. This is better for the driver and passengers.
Is Lamborghini getting rid of the V12?
After 10 years of production, Lamborghini is finally saying goodbye to the Aventador, and with it, its V12 engine. Lamborghini isn’t ditching the V12 entirely and is diligently working on a brand-new replacement unit that will share only its cylinder count with the current Lamborghini V12.
Is a V8 or V12 better?
In general, V12 engines are more powerful as more cylinders allow for more displacement, which in turn generates more power. It can often be heavier too (though this depends on what materials the engines are made from), so all else being equal, a V8 would offer a better power-to-weight ratio.
Why don’t V12 engines get high fuel mileage?
Because the V12 configuration has smaller swept volume per cylinder, there is a greater surface area to volume ratio with the V12 cylinder and, thus, greater heat transfer of the energy into the cooling system! That’s why it is difficult to get high fuel mileage with a 6 liter V12.
Why does Lamborghini use a V12 engine?
Ferrari and Lamborghini probably used a V12 for these reasons: The valve area is greater for 12 cylinders than 8 for the same capacity, no. of valves per cylinder and stroke:bore ratio, so it should make more power and rev higher.
How many cylinders does a V12 engine have?
On a V8, at any given time you will have a maximum of two cylinders on their combustion (BANG) stroke. On a V12, the timings are interleaved more so that during the majority of operating times, three cylinders are at some point on their combustion (BANG) stroke.
Why did Ferrari choose the V12 for his first car?
I’ve been informed by collectors that Ferrari chose the V12 because of the smoothness he witnessed with Ford built V12 engines in military transport vehicles during WWII. Ferrari’s first car, the 125, was only 1.5 liters in engine size but he chose the V12 configuration!
