Engine and Transmission Overview
The Ram 2500 6.4 Hemi is powered by a 6.4-liter V8 engine that is capable of producing 410 horsepower and 429 lb-ft of torque. This engine is paired with either a 6-speed or 8-speed transmission, depending on the buyer’s preference.
The 6-speed transmission option is a heavy-duty manual transmission that has been designed to handle the high torque output of the 6.4-liter V8 engine. It offers smooth shifting and efficient power transfer,
Making it a great choice for towing and hauling heavy loads. However, the 6-speed transmission may not be as fuel-efficient as the 8-speed transmission.
The 8-speed transmission option, on the other hand, is an automatic transmission that is geared for better fuel economy. It has been optimized for low-speed, high-load operation and is equipped with advanced features such as fuel-saving technology and intelligent shift scheduling.
This transmission also offers a wider gear ratio than the 6-speed, which allows for more precise gear selection and improved acceleration.
Another key difference between the 6-speed and 8-speed transmission options is the number of gears available. The 6-speed transmission has 6 gears, while the 8-speed transmission has 8 gears.
This can impact the driving experience as more gears can provide a wider range of gear ratios to choose from, which can lead to better acceleration and fuel efficiency.
Additionally, the 8-speed transmission is also equipped with advanced features such as adaptive shifting and manual shift control, which can provide a more personalized driving experience.
The 6-speed transmission, on the other hand, may not have as many advanced features, but it can still provide a solid and reliable performance.
In summary, the 6-speed transmission option in the Ram 2500 6.4 Hemi is best suited for heavy-duty towing and hauling tasks, while the 8-speed transmission option is geared towards improved fuel efficiency and precise gear selection.
It is important to consider your specific needs and preferences when deciding between the two options.
Fuel Efficiency
When it comes to fuel efficiency, the 8-speed transmission is the clear winner. According to Ram, the 8-speed transmission can improve fuel economy by up to 1 mpg in the city and 3 mpg on the highway, compared to the 6-speed transmission.
Additionally, the 8-speed transmission is also equipped with advanced features such as fuel-saving technology and intelligent shift scheduling, which help to further improve fuel economy.
Towing and Payload Capacity
The towing and payload capacity of the Ram 2500 6.4 Hemi with the 6-speed and 8-speed transmissions are similar, with both options capable of towing up to 17,980 pounds and carrying a payload of up to 3,160 pounds.
However, the 8-speed transmission has a wider gear ratio, which allows for more precise gear selection and improved acceleration. This can be beneficial when towing heavy loads and navigating steep inclines.
Cost
The cost of the 6-speed and 8-speed transmission options in the Ram 2500 6.4 Hemi can vary depending on the trim level and other features that are included in the vehicle. Typically, the 8-speed transmission option is more expensive than the 6-speed transmission option.
However, it is important to consider the long-term cost savings that can be achieved through improved fuel efficiency when making your decision.
Ram 2500 6.4 Hemi 8 Speed
The Ram 2500 6.4 Hemi 8 Speed is a great truck for those who need a little extra power and speed. This truck comes with a 6.4-liter V8 engine that produces 410 horsepower and 429 lb-ft of torque. It also has an eight-speed automatic transmission that helps the truck get up to speed quickly.
The Ram 2500 6.4 Hemi 8 Speed can tow up to 12,560 pounds, making it perfect for hauling trailers or other large loads. It also has a payload capacity of 3,060 pounds, so you can take everything you need with you when you hit the road.
Is 8 Speed Faster Than 6 Speed
Is 8 Speed Faster Than 6 Speed? The answer is yes, 8-speed is faster than 6-speed. Here’s why:
8-speed has twice as many gears as 6-speed. This means that 8-speed can shift between gears more quickly and smoothly than 6-speed. 8-speed also has a wider gear range than 6-speed.
This means that you can pedal at a higher cadence (revolutions per minute) without running out of gears. For example, if you’re pedaling at 90rpm in 8th gear, you could still shift to 9th gear and pedal at 100rpm.
In contrast, if you’re pedaling at 90rpm in 6th gear, the next highest gear would be too hard to pedal in and you’d have to slow down.
So, if you’re looking for a bike that will help you go faster, an 8-speed bike is the way to go!
6.4 Hemi Life Expectancy
The Chrysler 6.4 Hemi V8 engine is a reliable and durable engine that can last for many years with proper maintenance. The average life expectancy of a 6.4 Hemi engine is around 200,000 miles.
However, some engines have been known to last much longer than this with proper care.
With regular oil changes and tune-ups, your 6.4 Hemi engine can provide you with years of trouble-free driving.
Best Transmission for 6.4 Hemi
There are a few different transmission options for the 6.4L Hemi engine. The most popular transmission is the six-speed automatic, which is offered by Chrysler, Dodge, and Jeep. This transmission is also available with an eight-speed automatic.
Another option is the five-speed automatic, which was offered on early model 6.4L Hemi engines. The six-speed automatic is the best choice for most people, as it offers good fuel economy and performance.
The eight-speed automatic offers even better fuel economy, but it can be slower than the six-speed in some cases.
The five-speed automatic is not as popular as the other two options, but it can offer better performance in some situations.
