Group from Ireland -- vehicle shown in article, overturned (7)
I believe the answer is:
nirvana
'group' is the definition.
(US musical group)
'ireland vehicle shown in article overturned' is the wordplay.
'ireland' becomes 'ir' (abbreviation for Ireland).
'vehicle' becomes 'van' (van is a kind of vehicle).
'shown in' means one lot of letters goes inside another.
'article' becomes 'an' (indefinite article).
'overturned' is a reversal indicator.
'an' in reverse letter order is 'na'.
'ir'+'van'='irvan'
'irvan' placed within 'na' is 'NIRVANA'.
'from' acts as a link.
(Other definitions for nirvana that I've seen before include "Buddhist version of Paradise" , "Buddhist heaven" , "Iran van (anag) - blissful state!" , "Transcendent state of Buddhists" , "Transcendent state - US grunge band" .)
