Commandeer four-by-four across the Channel (5)

I believe the answer is:

seize

This clue is a double definition.

'commandeer' is the first definition.
(thesaurus)

'four-by-four across the channel' is the second definition.
('seize' is 16 or 4x4 in French)

(Other definitions for seize that I've seen before include "appropriate" , "Snatch" , "Get hold of" , "Grab by force" , "Grasp suddenly" .)

I've seen this clue in The Times.
