Which is better and which has lower fuel consumption compared to rear wheel drive or front wheel dri

Fuel consumption is similar to that of rear-wheel drive and front-wheel drive. The front-wheel drive is generally an ordinary family car, and the rear-wheel drive is generally a high-end luxury car, such as Mercedes-Benz, BMW, Porsche. The weight of four-wheel drive is much heavier than that of front-wheel drive and rear-wheel drive, so the fuel consumption of four-wheel drive is slightly higher. Hope.

Front-wheel drive or rear-wheel drive when buying a car?

Four-wheel drive car must be higher than the general household rear-wheel drive car fuel consumption, four-wheel drive car power enough, fuel consumption is large, which is well understood, the more power, the greater the fuel consumption.

Yes, this is because four-wheel drive vehicles will require more fuel and power, so the fuel consumption will be higher than that of ordinary family rear-wheel drive vehicles.

No, the fuel consumption of this car is the same, unless it is different compared to some luxury cars, and the other cars are similar.

Rear-wheel drive vehicles are more comfortable to drive than front-wheel drive vehicles. The front wheels are responsible for driving and steering. Rear-wheel drive refers to the transmission of power from the engine through the propeller shaft to the rear wheels, with the rear wheels responsible for driving and the front wheels responsible for steering.

To a large extent, it is true that the rear wheel drive is easier to do more advanced than the front wheel drive. As a result, the steering capacity is stronger. Front-wheel vehicles tend to cause understeer when cornering at high speeds, while rear-wheel vehicles tend to cause oversteer.

The oversteer is effectively controlled under the coordinated control of the EPC system to maintain high-speed steering stability.

1.Since the drive part of the front-wheel drive car is in the front, there are no drive components such as propeller shafts connected to the rear wheels, which not only reduces the mass of the original car, but also frees up valuable cabin space. It is connected to the engine gearbox, and then directly outputs power to the front wheels through the left and right drive shafts, which can reduce unnecessary power loss and fuel consumption; Since the drive and transmission parts of the front-wheel drive car are in front, the main weight of the whole car is concentrated in front of the body, and it is easy to understeer when cornering at high speeds.

Specifically, when cornering at high speed, the front of the car does not point to the inside of the curve, but to the outside of the curve.

2.Rear-wheel drive cars tend to adopt vertical mode, because the driveshaft is required to transmit power to the rear wheel axle, resulting in a longer front of the car, squeezing the use space in the car, and there will basically be a big bulge in the middle of the rear seat, because the driveshaft needs to pass through here, so the sitting position of the middleman is often very uncomfortable and awkward.

3.The mechanic said that the rear-wheel drive has better handling, because the steering and driving of the rear-wheel drive do not interfere with each other, and the rear-wheel drive can get a more precise handling experience when driving, basically reaching a 5:5 body weight.

The center of gravity is in the rear half of the car when climbing hills, and rear-wheel drive can provide more tire grip and the car has more acceleration ability. At this time, compared with the front drive, the advantage is stronger than the front drive, and the front drive pulls and runs better than the rear drive. The above is the answer to the question of which is more comfortable to drive, front-wheel drive or rear-wheel drive.

Front-wheel drive cars are more comfortable to drive, because not only is the space particularly large, but also particularly fuel-efficient, relatively speaking, the cost performance is relatively high, while the rear wheel drive cars are prone to wheel slippage in snowy days.

It should be that rear-wheel drive cars are more comfortable, front-wheel drive cars are not good at high-speed cornering, and rear-wheel drive models are more stable and more suitable for dealing with unexpected situations.

I think rear-wheel drive cars are more comfortable to drive, and some rear-wheel drive cars in Germany handle very well, such as BMW, Cadillac, and rear-wheel drive cars will be more personal.

I think the front-wheel drive car is more comfortable to drive because all the power is concentrated in the front of the body, which makes the car very fuel-efficient and reduces the cost of maintenance.

The fuel consumption of the rear wheel drive is higher, and the fuel consumption of the front hall leakage is lower because the front wheel drive is more efficient, and the rear wheel drive is not as efficient as the front wheel drive.

The front wheels are generally used by some family cars, and the fuel economy of family cars is also relatively good.

The engine and transmission of the front drive are arranged horizontally. The power output from this car's engine is transmitted directly to the gearbox, which then transmits the power directly to the wheels via the final drive differential.

Front-wheel drive does not change direction and transmits the power of the engine to the wheels, which is more efficient.

Typically the rear-wheel drive engine is vertical, and the car's engine power delivery is also transmitted to the gearbox, which has a drive shaft leading to a differential for the rear wheel axle.

In the rear axle differential, the direction of power transmission needs to be changed by 90 degrees, and then the power is transmitted to the wheels.

Due to the need to change the direction of transmission of primary power, the transmission efficiency of rear-wheel drive is low.

But most rear-wheel drive cars don't care about losing power because most rear-wheel drive cars have more horsepower than front-wheel drive cars.

The front drive can't withstand more horsepower, the rear drive can.

Due to the different lengths of the first two half-shafts of the front drive, if the horsepower is too high, the front drive will turn into torque when accelerating, which is not conducive to control.

Normally, the front-wheel drive is more fuel-efficient than the rear-wheel drive, and the mechanical components of the front-wheel drive car are few and simple, and the transmission shaft device is omitted, and the weight of the body is reduced a lot. However, fuel consumption is affected by many factors, such as vehicle conditions, road conditions, driving habits, etc., which require car owners to consider from many aspects.

From the perspective of car structure, front-wheel drive is relatively cheap to manufacture, because it does not need to transmit power to the rear of the car, there is no need for the drive shaft and rear axle housing, the transmission and differential are assembled in a housing, and fewer parts are required. At the same time, the front-wheel drive design can also reduce the weight of the whole vehicle, so that the fuel economy of the car is improved, because most of the mass of the vehicle is concentrated in the front of the vehicle, the adhesion of the front wheels can be increased, the braking ability is improved, and it is not easy to lock during emergency braking. The drive does not need to leave space on the floor for the rear-wheel drive equipment like the rear-wheel drive, so there is more leeway in the use of space.

However, front-wheel drive also has disadvantages, the front wheels are overloaded, the front wheels are responsible for both traction and steering, too many tasks are naturally not perfect, the steering is not precise enough, the front axle is overburdened when accelerating and braking, and the head and nod are more obvious, affecting comfort.

The advantages and disadvantages of rear-wheel drive are just the opposite of front-wheel drive, the rear wheel is responsible for traction, the front wheel is responsible for steering, the division of labor is clear, the whole driving handling will be improved a lot, the weight of the car is also more balanced, starting, accelerating, climbing is also more powerful than front-wheel drive, so sports cars and high-performance cars will use rear-wheel drive. However, rear-wheel drive is expensive to manufacture, and the power generated by the engine is transmitted to the rear axle through the propeller shaft, resulting in a loss of power output. There are many rear-wheel drive parts, and the assembly is complicated, and at the same time, the interior space is reduced.

However, with the adoption of the independent suspension system for the rear wheels, there is a lot of room for improvement in the space of the rear-wheel drive car. (Photo by Wu Binbin, Pacific Automobile Network).

Because rear-wheel drive is not as efficient as front-wheel drive, rear-wheel drive has higher fuel consumption than front-wheel drive. Transmission efficiency is also an important factor affecting fuel consumption. Rear-wheel drive due to the complex transmission system, large power loss, high fuel consumption is a normal phenomenon.

Most front-wheel drive vehicles are equipped with a front-transverse engine, and the drivetrain structure of this type of car is very simple.

If the engine is horizontal, so is the gearbox.

After the power of the engine passes through the gearbox, it can be directly sold from the section fiber gearbox with two half-axles connected to the wheels, so that the power can be transmitted to the wheels through the gearbox.

The engines of rear-wheel drive cars are all vertical, and the gearbox of vertical engines is also vertical.

In this way, the power output of the engine passes through the gearbox, and then the gearbox will extend a propeller shaft to the differential of the rear axle, and the differential of the rear axle will extend out two half-shafts to connect the two rear wheels, so that the power can be transmitted to the rear wheels.

Front-engine, rear-wheel drive cars have to go through a 90-degree change of direction during power transmission.

When power reaches the propeller shaft behind the gearbox, the propeller shaft transmits power to the differential on the rear axle. The power is in this part of the 90-degree commutation, and there will be some loss in the process of commutation.

There is no need to change the power direction of the front engine during transmission, so the power loss is small. Grip which imitation.
