FRANKFURT (Reuters) - Germany's Sixt said on Thursday it would launch a new mobility platform this year that bundles its traditional car rental and transfer services with a car-sharing offering, challenging carmakers BMW (>> Bayerische Motoren Werke) and Daimler.

Sixt in January sold its stake in car-sharing service DriveNow to joint venture partner BMW, which is expected to combine the company with Daimler's Car2Go in an alliance.
