Plus, the majority of the weight is positioned over the front wheels, offering good traction when its slippery. Rear-wheel drive used to be the most common drive system until the advent of front-wheel drive in the early 80s. However, RWD vehicles can handle more horsepower and higher vehicle weights, which is why it is often found in sports cars, performance sedans, big trucks, race cars, and law enforcement pursuit vehicles.
The RWD cars have always found a special place in the hearts of automotive enthusiasts as these RWD cars allow them to slide the rear end out. The RWD cars tend to have a better balance due to a more evenly spread out weight throughout the vehicle. RWD cars are usually known to handle more horsepower and vehicle weight, which justifies the fact that technology is used mostly in sports sedans, law enforcement vehicles, race cars etc.
Although, due to the driveshaft the cars tend to have lesser space in the interior and might not have great traction on slippery roads. FWD means that the power is being delivered to the front wheels of the vehicle. FWD technology came into the limelight in the s when manufacturers like Audi and Saab began adopting this configuration.
Most of the cars in India as well as around the world run on the FWD drivetrain. The front wheeled drivetrain is said to be more efficient due to its less weight which results in lower carbon dioxide emissions, gives better fuel economy, offers good traction on a slippery patch of road and gives a spacious cabin to the passengers. The four-wheel driven option tends to provide power to all 4 wheels of a vehicle providing much better power and traction. The 4WD vehicles are usually equipped with a transfer case which allows the car to change to RWD transmission in order to save fuel and get back to 4WD mode if and when required.
While both of them have all the 4 wheels running, and they run on the same principles, there are some key differences which set the two breeds apart. Most of the AWD vehicles these days are equipped with an engine control unit ECU which decides the amount of power and traction that a wheel gets unlike a 4WD vehicle which provides an equal amount of power to all the wheels irrespective of the situation, the car is in.
Which is the best drivetrain for India? At the end of the day, the drivetrain of the car does matter. You should go for a car that best suits your needs. The biggest advantage of a 4WD vehicle is that it provides the versatility and power to take on any terrain or weather condition. All-wheel drive: A drivetrain that employs a front, rear and center differential to provide power to all four wheels of a vehicle. As the name implies, all-wheel-drive systems power both the front and rear wheels all the time.
But in practice, there are actually two types of drivetrains that are called AWD. We want to help you understand the similarities and differences between the two main types.
If a vehicle features front wheel drive FWD , the transmission transfers power from the engine to the front wheels. Most of the time, front-wheel drive cars get better gas mileage because the weight of the drivetrain is less than that of a rear-wheel vehicle. FWD vehicles also get better traction because the weight of the engine and transmission are over the front wheels.
