This assessment gives a detailed comparison between a 12V VR6 and a 24V VR6. VR6 is a type of engine used specifically in cars. VR6 engines consist of V6 piston engines which have a narrow-angle between the cylinder banks and a single cylinder head covering both banks of cylinders.
Let us get into some details:
History of VR6
Volkswagen Group presented the principal VR6 motor in 1991 and VR6 motors as of now stay underway. From 1997 to 2006, Volkswagen additionally delivered a five-chamber VR5 motor in light of the VR6.
In comparison with a four-chamber motor, the VR6 is unnecessarily larger in size. This specification shows that the VR6 engine can be mounted transitionally in small front-wheel-drive cars without a hood with large space and size.
Volkswagen started work on a model 2.0-liter VR6 in 1978, however, when it was manufactured in 1991, the VR6 had developed to 2.8 liters to a great extent in order to address the issues of forcing hungry Americans.
The VR6 made its introduction in the Passat and found a home in the Corrado sports roadster presently. From that point, it multiplied into other VWs, including the GTI and the Jetta. The earliest adaptation of these motors had 12 valves while later models got 24.
Comparison Between VR6 12V and VR6 24V
Horsepower and Torque
Early VR6 12V motors had two valves for every chamber (for an aggregate of twelve valves) and involved one camshaft for the admission and exhaust valves of every chamber bank (without the utilization of rockers).
With two valves for every chamber, the first VR6 was created somewhere in the range of 172 and 178 hp, contingent upon the application. In any case, it wasn’t this motor’s result that portrayed it – – it was the VR6’s sound and perfection.
Without a doubt, the VR6’s refinement matched the best in-line sixes’. Now, this adaptation of VR6 has power going from 350 to 600hp. Despite the fact that the motor’s plastic cover said DOHC, the first VR6 was practically a SOHC plan, with every chamber’s valves activated by a similar camshaft.
In 1999, a 24-valve variation was conceived, additionally with two camshafts altogether, however, presently one worked all the admission valves while the other opened all the exhaust valves. Variable valve timing was presently conceivable, expanding VR6’s force bend .
The 24-valve adaptations utilize one camshaft for the admission valves of the two banks (utilizing rockers to arrive at the uttermost bank) and the other camshaft for the exhaust valves of the two banks (once more, using rockers). This working guideline is more much the same as a twofold upward camshaft (DOHC) plan, with one camshaft for consumption valves, and one for the exhaust valves.
The V6 12V adaptation has 5-speed manual transmission. With 172 BHP, the normally suctioned 2.8 Liter 12V V6 petroleum motor speeds up this Golf VR6 to 62 mph in 7.6 seconds and on to a most extreme speed of 140 mph. The 24V VR6 has Variable Valve Timing. It has 6-speed manual transmission.

These valves set the norm for all Turbocharged, Supercharged, Nitrous Oxide, and pressure confined race engines. These valves don’t require coatings. They are made with the best materials. The V24 VR6 is produced using the premium 300 tempered steel, which is evaluated at 170,000 psi elasticity. That is a lot more grounded than Grade 8 steel.
A valvetrain or valve train is a mechanical framework that controls the activity of the admission and fumes valves in a gas-powered motor. The VR6 V12 is the up-and-coming age of outrageous intensity safe valves, explicitly created to endure incredibly merciless discipline.
These studs are additionally, exceptionally consumption and intensity safe, for long assistance under the hardest circumstances, and they are cleaned to the mirror-like shine.12-point nuts.
V12 VR6 has a solitary chamber head. The benefits of having a solitary chamber head are that it has little relocation, a more modest motor, and it is simpler to bundle. It additionally utilizes moderately less fuel. This adaptation has lesser parts to break and lesser support cerebral pain. It is additionally lighter. The VR6 24V additionally has a solitary chamber head.
The Pros and Cons of VR6 12V
VR6 12V is the earliest model of VR6 motor fabricated and utilized by Volkswagen. The pros of adaptation of the VR6 motor are:
- It has an extraordinary low-end force. The benefit of having a motor with low-end force is that it gives a more loosened up driving experience. Assuming your vehicle has low-end force, it for the most part implies that you approach more motor power in lower gears. Subsequently, you wouldn’t need to down-change the gears so frequently while speeding up from low velocities, and the drive will feel looser.
- Another benefit of the V12 VR6 motor is that it has a sweet profound snarling exhaust note. Having a motor that has a sweet profound snarling fumes note upgrades the presentation of the vehicle. Be that as it may, swapping to the most stretched out distance across fume pipe would not improve power unless you have a truly strong motor. A fume pipe actually should be sufficiently restricted to improve fume gas’ speed.
The cons of using VR6 12V engines in cars are:
- The transmission time needs to be dropped to replace timing chains/guides.
- The cars are not able to produce as much power as VR6 24V engines.
- The cars have less torque than VR6 24V engines.
- The cars have a higher chance of oil leaks.
- The cars have a higher chance of engine failure.
The Pros and Cons of VR6 24V
The V12 version has the following pros & cons:
- The pro is that 24V VR6 has more transmission speed and it has 24 valves compared to the 12 valves in VR12. So, it will definitely increase the power of your car.
- The con is that this engine is more expensive than VR6 12V. So, you’ll have to consider your budget before making a purchase.
Is the 12v Just As Reliable As 24v?
In spite of the fact that there is a clothing rundown of issues recorded over, the VR6 24V motor is entirely dependable whenever kept up with appropriately. They can run for up to 150,000 miles or significantly longer, we have seen some last longer than 300,000 miles.
The assessment has given a detailed comparison between the V12 and V24 versions of VR6. Keeping in mind the above facts it is concluded that V24 version having 24 valves is more reliable as compared to the V12 version of the same engine. This version enhances the performance of cars. Using this model can be relatively more expensive, but the specifications pay their price.
Keep in mind that each person’s opinion will differ on what is important to them in a car. Some people may find that the increased power and torque of the VR6 24V engine is worth the extra cost and maintenance, while others may prefer the lower price and easier maintenance of the VR6 12V engine. The best way to make a decision is to test drive both types of cars and see which one suits your needs the best.
