Why are all Mustangs rear-wheel drive?
Because the guys who built the Mustang have chosen to make it rear-wheel drive. There's nothing more to it, really. A design choice. Like BMW chose to make the majority of it's cars also rear-wheel drive (recently there's more all-wheel drives coming from BMW). Or just like VW chose to make the majority of it's cars front-wheel drive, etc..It's true that a lot of sports cars are rear-wheel drive. Mustang, Corvete, Viper, BMW, etc. . This may be because the handling is better in cars where only the rear wheels drive the car, so that the traction on the rear wheels is used to move the car forward (occasionally backwards ). While the whole traction on the front wheels goes into handling the car. Meaning the front wheels(friction) only need to care about how to keep the car on the road/track and make it take curves fast and safe. That's why (almost)all race cars are rear-wheel drive. Think Formula, GT, Le Mans, etc. . Also Dragrace and Nascar but for those see Tim Hofstetter's answer for a reason.Note that I was taking a guess here because I don't know why exactly they chose to do so or in what this decision was based.NOTE. There's also race cars like those that compete in Really races that are 4wd but the thing is that in Really races the track is mostly not asphalt/concrete. Usually the tracks are asphalt mixed with mud or mud and snow, etc. .And there are also sports cars like the big ones. Ferrari(FF), Lamborghini, some versions of Porsche, etc. that are awd. All of these models made in the last couple of years have the power divided asymmetrically, always in favour of the rear wheels. Some even argue that these cars are just sophisticated 2 wheel-drives because, in the case of automated awd, not all of the four wheels are driven at the same time. The front wheels are engaged only in certain cases. What all of these cars have in common is the placement of the engine in the 'back' (actually it's in the middle ) of the car.
What are the pros and cons of a maltese and chihuahua?
I dont know about maltese maybe you have to get them groomed because their hair grow but chihuahuas are very fragile they get hurt really easy thats the only problem with mine.
What is the difference between automatic and semi-automatic cars?
Automatic transmission in a car means that the gear changes are all done by the car.These sticks means that the car is completely automatic - you only need to put it on drive mode, and the car will do all the necessary gear change by itself.P is park,R is Reverse,N is Neutral, meaning the car can roll by itself,D is Drive,The lower 2 may changed, but those two are options to lock the gears in one gear ratio. L is the lower gear, and 2 only allows the car to use first or second gear.However, the semi-automatic is different in that while it does not change gears by itself, it instead “helps” the driver switch through gears.(They are also called paddle-shift gearboxes, because there are usually paddles on the back to change the gears)The semi-automatic transmission has no need for a clutch for this reason - it does it for the driver.So, all the driver has to do is tell the car what gear he wants, and the car does it for him/her.For semi-automatic cars that have a stick for gear changes, they have up or down :Modern semi-automatic cars usually do have a automatic gear change option as well. The picture above shows the gears in semi-automatic mode, but if the driver pushes it left, it will be automatic.So basically:A semi-automatic has the driver order the car to move up or down a gear,An automatic has the car doing everything for the driver - the driver doesn’t have to worry about gears at all.
