Difference between 4 Wheel Drive and 6 Wheel Drive

Difference between 4 Wheel Drive and 6 Wheel Drive

Whenever we go to a showroom, there are different types of car ranging from 4-wheel drive, All Wheel Drive (AWD) and many more and today we are going to tell you the difference between 4 Wheel Drive and 6 Wheel Drive.

4 Wheel Drive is of the most well-known feature in cars and its main purpose is to get you out of muddy regions and in a four-wheel drive, power is sent equally to all four tires regardless of the car-type you have (Front Wheel Drive or Rear Wheel Drive) and in a 6 Wheel Drive or 6X6 car, power is sent to all six tires and a 6X6 car can get you out of any terrain because of its tough engine and an extra set of tires.
Who buys this type of cars?
4 Wheel Drive:
4 Wheel Drive is used by every normal person even if they are an off-road fan or not and in today’s time, almost every car company makes an SUV which has the feature of 4 Wheel Drive.
6 Wheel Drive:
Now, a handful of people buy a 6X6 car because first of all, very few companies are there who make this type of car and second is that, 6 Wheel Cars are available at high prices like Mercedes-Benz G63 AMG 6X6 which costs you around Rs 2.19 crore and is out of a normal person’s budget so, a 6X6 car is usually used for military purposes.

In India, there is only one company making a 6X6 automobile that is Ashok Leyland’s Field Artillery Tractor (FAT) and in 2017 Ashok Leyland, became the first Indian automobile company to manufacture a 6X6 military vehicle after Scania’s SBA11 was discontinued from 30 years of service by the Indian Government and Ashok Leyland replaced the Swedish Company (Scania) and won the contract of supplying 450 units of FAT 6X6 to the Indian Army.

Differential Lock

Differential Lock

A differential lock is very important equipment in a car and the main purpose of a differential lock is to transfer power separately to both tires and a common theory on why a differential lock or diff lock is used in a car is mentioned below:
Now, when a car makes a turn then its inner tire have less movement compared to the outer tire which has to rotate more in order to move the car so, the outer tire has more strain on it, compared to the inner tire which makes less rotation and the diff lock is the solution to the problem as it rotates both tires in equal speed and a differential lock is located on the center of the axle and it can be in the front or back, depending on the type of car you have, front-wheel drive or rear-wheel drive.

And in differential lock there are two types:
1. Locked Differential
2. Open Differential
- Locked Differential:

In a locked differential, power is sent equally to both tires and instead of moving at different speed both tires move at the same speed and it helps the car to have traction on slippery roads and a locked differential can be seen in professional racing cars or drifting cars where the car needs high traction and at the same time in full speed.
- Open Differential:

In an Open Differential, power can be transferred to a single tire depending on the constraint and both tires rotate at a different speed, to understand better let’s see an example:

You are off-roading your car and suddenly your car’s right rear tire is stuck in a big hole and you’re constantly putting your feet on the accelerator but the car is not moving, because only three tires have traction on the land while the fourth tire has no traction and is hanging on the air and whenever you accelerate, both tires move at an equal speed so, the power is utilized to only one tire (left rear tire) and the right rear tire is wasting power because it has no traction so, the answer to this problem is an open differential system and as soon as you turn it on, whole power will shift to the tire having most traction which is the left rear tire in this scenario and your car will be easily out of the hole.

Apart from normal cars, an open differential can also be seen in a tractor and it can be turned on by pressing a small pedal which is perfectly placed below your heel.
How to use a differential lock?

Step 1-

As you turn on the switch, the car will show a diff lock sigh in your automotive head-up display and now, slowly press your feet on the accelerator pedal and move the car.

Step 3- 
Once, you gain traction in all four tires, stop the car, turn off the diff lock switch and continue your journey.

In today’s time, you can see a differential lock in almost every second car in India and one of the pioneers to bring the diff lock feature in India, has to be Force Motors who introduced the first generation Gurkha in 2008 and it came with a manual differential lock which can be used through a lever and the latest car coming with a diff lock feature is the 2020 Mahindra Thar and it has a mechanical differential lock and it does not require a switch or lever to start as the system automatically turns on, when it senses wheel speed difference of over 100rpm.

Mitsubishi Pajero’s dominance in Dakar Rally

Mitsubishi Pajero’s dominance in Dakar Rally

The Dakar Rally is world’s toughest rally event where drivers and their cars go to their limits in the process of covering 7,000 kilometres in space of 14 days. Usually, when a family have a long trip then, the average distance is 500kms which includes reaching the destination and coming back.
In Dakar Rally, every car covers an average distance of 500 km in a single day and this continues till the team reaches the finish line and last year, the rally was held in Saudi Arabia with a total distance of 7,900 km.

First Generation Pajero

The Dakar Rally was started in 1978 and three years later, Mitsubishi made their debut in the Dakar Rally and the Mitsubishi Pajero is considered as Mitsubishi’s greatest asset and one of the best contributions to the world of off -roading and rally. Pajero or they say Montero in North America, is one of most iconic cars and is renowned for its suspension and speed.
The first generation Pajero was used in 1983 Dakar Rally and in its first attempt, Mitsubishi Pajero completed all stages and successfully finished the race at 11th position without any engine failures or retirement.

Next year, the Mitsubishi Pajero got its first podium in Dakar Rally which was a third-place finish in 1984 Dakar Rally and in 1985, Mitsubishi Pajero won the Dakar Rally for the first time and became the first Japanese team to win the world’s toughest rally. After having a great start and winning the Dakar Rally in their third year was a great achievement but later, Mitsubishi were not able produce the same magic by the Pajero for next 7 years because Mitsubishi didn’t win the Dakar Rally from 1986-1991. Not having won the event for 7 years was a tough thing but what came next was amazing as they won the Dakar Rally not once but twice as Mitsubishi won back to back Dakar Rallies in 1992 and 1993.
In just 10 years, Mitsubishi Pajero got five podium places and three overall wins and again the empty run came as Mitsubishi didn’t get any overall victories in next three years (1994-1996) but they did get three podiums in 1995 and 1996.

During this time France’s Citroen was quietly pushing their competitors because from 1987 to 1990, Mitsubishi and Peugeot dominated the Dakar Rally for four years until, Citroen elbowed both giants and won the 1991 Dakar Rally for the first time, followed by double podium finish (second and third) in 1993 and this three podiums and one win, boosted Citroen’s confidence as the French team won three Dakar Rallies in a row (1994-1996) with same drivers Lartigue/Perin and the car reached to its full potential and there were few cars who could challenge the duo Lartigue/Perin as they were relentless.
Japan’s Shinozuka along with his co-driver Fontenay won the Dakar Rally for Mitsubishi in 1997 and Kenjiro Shinozuka became first Japanese driver to win the Dakar Rally. So, Mitsubishi came back strong by winning back to back Dakar Rallies and the team had two dominant seasons as Mitsubishi got first-four places in overall standings in 1997 and 1998.
In the next two years, Renault won back to back Dakar Rallies in 1999 and 2000 while, Mitsubishi dominated remaining podium places in these two years.
Before the new millennium started, Mitsubishi motors announced that they are going to introduce a new line of cars and its design was inspired by their own creation the “Pajero” as Mitsubishi introduced the third generation Pajero or Shogun in 1999. The third generation Pajero was special because it was built from zero to complete beast and the car was officially used in Dakar Rally.

The Mitsubishi Shogun got its first taste of success in 2001, when Kleinschmidt/Schulz won the 23rd Dakar Rally and in the same rally, Jutta Kleinschmidt became first female driver win the prestigious Dakar Rally.

Now, this was start of a brilliant run as the third generation Mitsubishi Shogun went on to win six more Dakar Rallies so, the Mitsubishi Shogun won 7 consecutive Dakar Rallies in seven years from 2001-2007 and the reason of that strong performance was because of the spectacular Shogun which had an independent suspension, great stability and an ability to produce great speed on sand and many more qualities, that made the Shogun different from its rivals.
The 2008 Dakar Rally was cancelled due to security concerns and in 30 years Dakar Rally’s history (1978-2008), this was the first time it will not held and what looked like an adversity, was a beginning because an alternate event was born, “African Eco Race” and two event were held in 2009 (Dakar Rally and African Eco Race).

On 4th February 2009, a sad news came from the Japanese Automaker that, Mitsubishi Motors are going quit from the Dakar Rally. And after winning the Dakar Rally for a record 12 times (including 7 in row) from 26 entries and were competing in the world’s toughest rally for 26 years (1983-2009) and lastly, the most dominant car in the Dakar Rally, “the Mitsubishi Pajero” and the Japanese car manufacturer (Mitsubishi) finally called time and left the Dakar Rally forever.
