A method for providing a data record of a vehicle to a third party includes: receiving a cryptographic key pair including a public, cryptographic key and a private, cryptographic key; receiving the data record of the vehicle; encrypting the received data record by the public, cryptographic key; transmitting the encrypted data record to a data memory for storing the encrypted data record; generating a cryptographic hash value for the encrypted data record; transmitting the hash value of the encrypted data record to a blockchain database for storing the hash value of the encrypted data record; receiving a request message from a third party for retrieving the data record; generating a first request message to the data memory and a second request message to the blockchain database on the basis of the received request message; transmitting the first request message to the data memory and the second request message to the blockchain database; receiving the encrypted data record from the data memory in response to the first request message and the hash value of the encrypted data record from the blockchain database in response to the second request message; validating the encrypted data record by the hash value; and, when validation of the encrypted data record is successful: decrypting the encrypted data record by the private, cryptographic key; and transmitting the data record in response to the request message from the third party to a server of the third party.

A permanent mold has a base made of metal. The base has a plurality of first mold portions, which are mutually spaced along a longitudinal axis and which are designed to shape a bearing tunnel of a crankcase. Second mold portions are arranged on the first mold portions and consist of a mold material.

Ingot mold and process for manufacturing a crankcase

The speed of a motor vehicle causes the production of an air flow which can produce disturbing noises at edges of motor vehicle components. To provide a motor vehicle in which disturbing noises due to the air flow when travelling are avoided, at least one spoiler element is provided, or in that a plurality of spoiler elements are provided. The respectively present number of spoiler elements is formed upstream and/or downstream of at least one existing edge of the particular component acted upon by the air flow. The number of spoiler elements is arranged and/or shaped in such a manner that the air flow striking against the respective spoiler elements is dispersed non-uniformly.
