BMW cars or Audi cars?




joey


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.

Rear wheel drive tires question.?

Would it be correct to put the "better" or more-tread tires on the front on rear ? I have heard varying answers, that the better tires should be where the power is (rear), or that they should be on the fronts because of steering. Both seem logical.


Answer
It really depends on the tire size, including the tire width, and the vehicle size and weight.
for instance, if you have a 4,000 lb. vehicle like a luxury car that has narrow tires (like 215.75.15) it would be better to put the newer tires on the front. You aren't looking for optimum traction, just safety, so it's worth while to put the meat where 60% of the weight is, and 70% of the stopping effort is provided. On bigger, longer RWD cars most of the weight is in the front. it's more controlable to have a tail-wag condition (rear swings to the sides AKA understeer)than a plow condition (front end goes straight even when steering wheel is turned AKA oversteer).
If you have a smaller car that has a wider tire like a sports car with a 235.60.15, than that car is engineered to be more even in weight distribution and it might be worth while to put the tires in the rear.
