On the basis of our general assumptions for the development of the world economy and of the automobile markets important to us, Mercedes-Benz Cars assumes that its unit sales in 2021 will be significantly above the level of the previous year.
This expectation is supported by the ongoing renewal of our attractive and innovative model portfolio. We intend to launch more than half a dozen new and revised models in the year 2021. Both the new GLB and the new S-Class should contribute towards the positive sales development.
We continue to systematically expand our global production network for electric mobility. The sub-brand Mercedes-EQ, which stands for electric intelligence, offers vehicles with all-electric drive. We intend to electrify the entire portfolio of Mercedes-Benz Cars by 2022. By 2025, we assume that up to 25 % will be purely electric cars. By 2030, plug-in hybrids and all-electric models should account for more than 50 %.
Mercedes-Benz Vans plans for a slight increase in unit sales in 2021 compared with the previous year. In the EU30 region, rising unit sales of our vans with electric drive should offset the discontinuation of the X-Class. In addition, we anticipate significant sales growth especially in North America. In China, we expect slight growth in unit sales.
Following the decline in demand in 2020, a recovery of important truck markets is expected this year. This should have a corresponding positive impact on unit sales by Daimler Trucks & Buses, which therefore anticipates significant sales growth in 2021. This development will be mainly driven by our expectations for the markets in North America, Indonesia, and the EU30 region.
Daimler Mobility anticipates a slight increase in new business and a contract volume at the prior-year level in 2021. We aim to utilize new market potential in the used-vehicle market and with more flexible leasing and rental products, especially for electric vehicles. And we intend to make use of additional market opportunities and enhance customer satisfaction with the continuous expansion of our online sales channels.
We see further growth potential in fleet management, the insurance business and mobility services, especially in the luxury segment.
On the basis of our assumptions concerning the development of automotive markets and the divisions’ planning, we expect the Daimler Group to achieve total unit sales in 2021 significantly above the level of the year 2020.
