No. A character in Body mode is not also in Bot mode.
This means that cards like Escape Route do not flip a Body mode character to Alt mode. For an example of a card that works with both Body mode and Bot mode characters, look at how Mission Briefing explicitly says 'in bot mode or body mode'.
Note that cards like Start Your Engines and Hunker Down do not flip the characters from Body mode to Alt mode, however if the characters have Car and Tank traits respectively, they still get the secondary effects of those cards.
