BMW cars or Audi cars?

Q. Which one makes better and more reliable cars I think BMW but I want to know which one you guys pick.


Answer
Audi is the youngest of the three german luxury car makers and is quickly on it's way to the top. having already surpassed Mercedes in sales, its only a matter of time until they overtake BMW. Audi is still innovating while both BMW and Mercedes have seemed to stop. Audi started the mid engine car, then they revolutionized all wheel drive and dominated rally races with the quattro. after that, they started pushing with turbocharged engines for smaller lighter more efficient engines that could still develop power. they also started dominating with lightweight strong chassis with the aluminium spaceframe which culminated in the audi r8 one of the best supercars of all time. now they are dominating le mans races with diesel hybrid technology planned to be part of a hypercar to compete ferrari, porsche, pagani, koenigsegg and mclaren.

BMW on the other hand are very good driver's cars. most BMWs are rear wheel drive with naturally aspirated (no turbos or superchargers) engines. they have very good chassis setups as well as suspension technology. BMW has always said that the chassis of a car must always be better than the engine. this setup allows a driver to really push a car to its limits with less fear of the car becoming unbalanced. their naturally aspirated engines respond with no turbo lag and with a smooth power delivery to help drivers get power down to the rear wheels precisely when they want it. BMW has also revolutionized interior technology for drivers. the iDrive centers paved the way for interior computer controls allowing for drivers to change an unheard amount of settings in the car. (settings range from simple creature comforts like time to turn off lights after engine shutdown, to how fierce the gearbox is or how stiff you want the suspension) BMW allows for a driver to have a car to behave exactly how they want it at any speeds.

in my opinion I like audi better than bmw. seeing as how they are comparable cars, they will have similar power and interior features. most audis are 4 wheel drive which have better traction to the rear wheel drive systems in most BMWs. Audis produce similar power to BMWs with smaller engines because of their turbos. audis tend to have more interior space especially for rear passengers because they are more designed to be family cars rather than sporty cars.
Audi also seems to be innovating more than BMW or Mercedes. BMW has almost removed itself from leading motorsport F1 while Audi is still leading in le mans where technology developed for racing is till being ported over to read cars. audi has also led more consistently in their motorsports fields with some of the greatest innovations of all time. they can be acredited for the mid engine, full time all wheel drive, diesel technology and recently the combination of electric and diesel powerplants to make a diesel hybrid for unrivaled fuel efficiency proving to be a killer on the long track and long race of the 24 hours of le mans. I've never trusted a car maker that's not involved in motorsports. not having the trust in your systems and engineers to compete scares me. this is the reason why I will never drive a kia as they still have never made a sports car.
audis also have the benefit of being closely related to VW cars which might allow for some slightly cheaper repairs if a VW dealership will accept it.

there really isn't a best, just what you feel is best for you. for me, that's an audi. the benefits of a smaller engine, all wheel drive and larger interior are better than a sporty more customizable driving experience even if I do enjoy sporty driving.

just remember that reliability is quite hard to measure on new cars since there aren't many accounts of them being broken. you can expect both makes to have great reliability if you take good car of them. what you are really paying for is the innate reliability of a really well made car. what sets them apart from each other is the features that make them best for you.

Did we have these luxuries 10 years ago?

Q. I'm trying to figure out how fast we're advancing.. I can't remember how the phones were like, if we had 3D, liquid crystal/plasma screen TVs, electric cars, motion sensor luxuries (games, TV), or if we had any touch screen devices (notepads, laptops, screens) in year 2000.
I'm not here to cry about how bad things are wherever you live, but to think about how well the human race is progressing technologically..


Answer
we had some motion sensor type things, i dont remember having a flat screen back then or touch screens. i dont believe we had electric cars til a few years ago. i never saw one til one backed into my car in a Hilton parking garage in LA (go figure). we did have cell phones then but they were giant green screen ones. on computers, i just remember those giant monitors with the separate keyboards. truth is, most electronic companies, mainly phone companies, release a new model/updated version of a product every 3-4 months so we're constantly advancing all the time on everything. in a lot of ways its extremely helpful but i also think we were much better off 10 years ago without all the fancy gadgets cause society is just get crappier the more advanced we get.

Other than the starting and stopping an engine, what exactly makes the instrument panel lights go off?

I am researching development of a Hybrid Electric Vehicle and I am trying to determine if power provided by an alternator from an electric motor to the battery or wiring harness will cause the dash lights to go off as it would normally when the engine is started. I want to turn the ignition to the on position and have the dash lights go off, instead of remaining on and hearing a chime. What is the actually electronic action that terminates the lamps and chime from working when a vehicle is started?


Answer
I'm having a little trouble figuring out what you want to do.

When the ignition key is set to ON various systems perform a self test. Part of the self test is to light the idiot lights on the dash make sure they are working and not burned out.

The oil pressure light comes on because the engine is not running causing no oil pressure. Once the engine is started the oil pressure comes up and when it reaches a set point the light goes off. If the pressure is below or falls below the set point the light will come on. The alternator light comes on because the alternator is not spinning generating electricity. The air bag light comes on during the self test and goes out if the test passes, the service engine light is the same way.

As for the chime it usually sounds because the seat belt isn't fastened. I've never owned a luxury car so I don't know about any other sounds that are made.

If you just want to listen to the radio you set the key to the ACCessory position. This leaves the engine and driving systems off conserving power.

What kind of new car technology means - hybrid, crossover, diesel, etc?

There are so many different cars out there now. I don''t plan to buy one soon but I'm having curiosity about things like hybrid, electric, hydrogen - as well as smart cars, crossovers - as well as diesel, unleaded, premium gasoline. What's with all these choices? Couldn't they agree on one! Thanks!!! Cheers!


Answer
Hybrid cars are cars that run on two sources of energy.
The first Hybrid was the Honda Insight in 2001 in America. It was a gas-electric hybrid. This means it used an electric motor when driving slow and a gas engine when driving fast. It got 60mpg city and 66mpg highway. The most popular Hybrid right now is the ugliest. The Toyota Prius.

Crossover is an SUV sitting on car chassis. The Honda CR-V is an AWD, higher, bigger Honda Civic. The Toyota Rav4 is sitting on Toyota Corolla chassis. The new Toyota Venza is a taller Toyota Camry, and so on.Crossovers hae been around for at least 2 years, but they are not getting more popular because of gas mileage.

Diesel is a different type of engine. This has been around for over 100 years. It is just starting to become popular in America, but just about every car sold in Europe has a Diesel engine option. Diesel engines work different than gas engines. They are much better on gas/petrol and they are used for towing heavy things. That is why Semi trucks and Lori's have Diesel engines. They are very reliable too. But they are slow cars and Diesel costs more than gas these days.

Electric cars are cars that run on just electricity. They use thousands of laptop computer batteries that would make the car last 40-200 miles before needing a recharge. Recharging is just plugging them into the wall and waiting 10-15 hours.

Hydrogen cars are cars that are powered by Hydrogen gas. This is highly compressed water. Right now, the only Hydrogen powered car in production is the Honda FCX Clarity. It is only sold in California because California is the only place with Hydrogen filling stations. Hydrogen cars make no pollution. All that comes out of the exhaust system is water that you could drink. They are very clean cars, but expensive to make. Hydrogen cars are also known as Fuel Cell cars.

Unleaded gas is gas that most cars use. When a car says to use unleaded fuel, they mean do NOT use Diesel. If you put Diesel in a gas car, you will break your car. There are many type if unleaded fuel. Regular(80-86 octane), Midgrade(88-89), Premium(90-93), Super(95-96) and Race(100+ octane). Cars with Turbochargers, superchargers, or powerful engines require premium fuel. All luxury cars like Acura's, Lexus, Infiniti, Audi, BMW, Cadillac, Lincoln, Mercedes, and others all require premium fuel. Honda Civic Si and VW GTI and Nissan 350z and almost all sports cars require premium fuel. Higher octane basically means beter quality. Putting Premium fuel in a car that just needs regular fuel does NOT make it more reliable or get better fuel economy. All it does is add about 5HP more to cars that recommend regular fuel.

Air powered cars are cars that run on compressed air. The compressed air is what moves the cylinders in the engine to make the car move. They could travel about 200 miles before needing more air. These cars are only sold in India so far. They have been around a few years.

Smart is a company made by Mercedes Benz. They make 3 cars. The Smart Fortwo, Smart Forfour, and Smart Roadster. In America, we only have the Smart Fortwo, which actually came out in 1998 in Europe. It is an old design. It is a regular gas powered car with a small 3 cylinder engine. It only has 70HP and is now the slowest new car in America. With its lightweight and small engine, you would expect it to be great on gas, but it is NOT. It gets 41 miles per gallon at best. A Honda Civic almost gets that. And the Smart Fortwo only seats 2 people. They are very unreliable and break down a lot. They use Premium gas. They are expensive to maintain. They are very bad cars. Old technology.
