Jaguar is seeking a new advertising agency following a rebranding campaign blunder six months ago, developed by Accenture Song and Spark44.The company has not officially commented on the rumor but Accenture Song is contracted until mid-2026.The review of the advertising agency is reportedly triggered by the 25-percent tariffs imposed by President Trump on imported cars from the UK.Jaguar aims to emulate Land Rover's business model by selling fewer cars at a high price, but it has faced challenges with the repositioning strategy.
