What is difference between normal and a 4 wheel drive car
Answers:
Answer
There are a variety of drivetrain formats for cars there is no "normal" one. 4 wheel drive describes engine power is sent to all 4 wheels.
Here are the typical abbreviations to describe drivetrain layout, for 2 wheel driven layouts.
FR- Front engine, Rear powered wheels. (Corvette, Mustang) FF- Front engine, Front powered wheels. (Civic, Eclipse) MR- Mid Engine Rear powered wheels. (MR2)
As for the all wheel drive layouts.
FA- Front engine all wheel drive (Jeep, Hummer, Subaru) MA- Mid Engine all wheel drive (Lamborghini) RA- Rear Engine all wheel drive (Porsche)
Some cars may have the AWD designation they may not be AWD 100% of the time either. some designs are on demand AWD. Mercedes 4 matic comes to mind.
Why the complex answers? Either the car drives with 2 wheels or 4, it is marked 4 wheel drive somewhere on the vehicle. A push button on the steering column, words 4x4 on the side of the vehicle, a four wheel drive shifter on the middle of the floorboard. Just because it is designated as a 4x4 does not necessarily mean all 4 wheels are pulling at the same time. A true 4 wheel drive would be almost impossible to steer on an asphalt or concrete roadway.
The last statement is the correct one. A true 4 wheel drive vehicle is hard to find because most surely if it is true 4 wheel drive either you couldn't drive it on the concrete or you will for sure brake something in the drive train.
Not at all. I owned a '76 4WD Chevy Blazer. When I purchased it, it had power only to 1 front wheel & 1 rear wheel when I had the Transfer Case in 4H or 4L. I added a Locking Differential to both, front & rear axles. From then on, when in 4H & 4L, power was delivered TO ALL FOUR WHEELS AT ALL TIMES. I did indeed have what you term "True 4WD". For concrete & other dry surfaces, I stayed in 2WD. (Personal note: The only reason I no longer have that Blazer is because in 1989, Ohio passed a Bumper Height law. My Blazer exceeded the height limit by several inches & I was unwilling to invest the cost of lowering it down to legal height).-LubeExpert
