No. They are losing support as their voter base is more right leaning but currently support a center left government. Tactically, that’s a tricky situation to be in.
And, no, they didn’t promise „fancy technology“ to solve all problems. They actively support monetary and regulatory climate change mitigations. However, as Germany’s only classical liberal party they want the government to take a mostly neutral stance on _how_ we mitigate climate change meaning technology decisions should be done by the private sector. That’s why they are actually in favor of carbon taxation and emissions trading (both of which happen to be already a reality for years in Germany) but don’t want the government to prohibit combustion engines.
While it is unclear what future role such engines play in private transport, there might be many niches where they are necessary: For generators, lawn mowers (because you don’t want to have a cable dangling next to rotating knives), agricultural machines and possibly trucks.
And that’s why I do think it is actually a reasonable point of view.
