Drives a car hard
New car: do you have to drive in a car?
Is it still necessary to drive in a new car today? Why you should take it easy and how to properly drive in a new car - the most important information and tips from the ADAC experts.
Avoid excessive revs for the first few kilometers
Defensive driving is good for the development of tire grip
A higher brake pressure is possible for the first few kilometers
Your new vehicle is ready to go in the dealer's yard and you would like to drive it out to the full right away? That's understandable, but not a really good idea. Because every new car should if possible retracted optimally become.
Avoid driving at high speed for the first few kilometers or unnecessarily stressing the brake pads with hard braking maneuvers. Then you will not only enjoy your new car more, but also longer.
Why do you have to break in a new car?
According to ADAC experts, the following generally applies: As a rule, running-in has lost much of its importance in modern vehicles, but one moderate handling with the new car does no harm.
First and foremost, the break-in affects the components engine and gears. This is because numerous mechanical parts, such as pistons and cylinders, easily rub against each other during operation. Since small inaccuracies still occur today - despite ever more precise manufacturing processes in the production of new cars - the mechanical parts have to stay together for a certain period of time run in first. Only then do they fit together optimally.
Thanks to lower manufacturing tolerances, the intervals between oil changes, for example, have increased significantly today. In the past, the first oil change on new cars was sometimes carried out after 1000 kilometers, the second at 5000 and the third at 10,000 kilometers Abrasion in the oil get rid of early.
Modern vehicles can partially with the first oil filling up to 30,000 kilometers because the more precise production and more precise washing processes prior to assembly mean that significantly less metallic abrasion ends up in the oil.
Basically: Please note (if available) the Notes on running in in the operating instructions for your vehicle.
What do you have to consider when breaking in a new car?
With this rule of thumb, you can generally drive in a new car well:
New car = considered driving style
In the beginning, accelerate as slowly as possible and avoid permanently in any case high speeds - especially if the engine is cold. Also, many and extremely short distances within a short time are rather disadvantageous when running in. Follow this recommendation for the first 1000 to 3000 kilometers.
Rather defensive driving is also good for them Adhesion development of the tires. Bring new tires during the first approximately 500 kilometers if possible not to your liability limit.
What has to be run in?
When running in, you should definitely keep an eye on the following components: engine, transmission, brakes, tires.
Breaking in the gearbox and engine
Do not overstrain either component during the break-in process - this is especially true for the engine. You should always handle a gear unit with the given caution.
Do not turn a diesel engine over about 3500 revolutions during the running-in process, a gasoline engine not over about 4500 revolutions. But applying the accelerator vigorously at low speeds is also disadvantageous because it increases the frictional forces in the engine and transmission. For the first few thousand kilometers you can do that speed and the Increase the maximum speed continuously.
You should also not use the maximum speed allowed for your new car at the beginning, because the engine speed will then be permanently high.
Breaking in the tires
The tires on new cars (and of course new tires in general!) Can only be used after a few hundred kilometers maximum grip level develop. Be particularly careful on wet roads: the braking distance with new tires is longer than with run-in tires.
Breaking in the brakes
The brakes are usually after a few braking maneuvers retracted well. The lining and disc are ground onto each other. Make sure, however, that a higher brake pressure may be possible for the first 200 to 300 kilometers so that you can achieve the same braking effect as with the brakes retracted.
Retraction of the landing gear
In comparison, the running-in process is far less important for the chassis. The mechanical components shock absorbers, springs and axle joints thank you in case of doubt longer lifespanif they do not have to carry and cushion a maximum load immediately during the running-in phase.
Drive in the car - this is how it works
Basically, you should be about to break in the new car at first 500 to 1000 kilometers If possible, do not push it to its technical limit, regardless of the components.
Long, leisurely tours overland are ideal for retracting.
