I don't have one of those devices but from a quick google search, it seems as if the only way to connect it to the web is via a mobile app they provide. Perhaps you can ask the manufacturer or check the instruction manual? There is no way to analyze the data in bluemix if you can't get it from the car to bluemix. It is a common architecture for this to be via a phone (Bluetooth to the phone and then wifi or mobile network to the WorldWideWeb). Which is why it becomes important to consider the impact on the phone's battery life and the cost to the user of the amount of data transferred and minimize both.
