Lexus has re-thought its plans to sell only hybrid versions of its models in Europe.
The new GS, which is just being rolled out across the UK, will be available with a 2.5-litre petrol engine by popular demand.
Paul Van der Burgh, director of Lexus Europe, said that customers, particularly in the top-selling countries - Russia and the UK - still want the option of a petrol engine rather than a hybrid.
He said: "There are some 7,000 petrol GS owners out there since the car was launched in 1993 and they have remained loyal to us and we want to keep them.
"We are making petrol models for other markets around the world so there is no great cost implication in making them available for Europe."
The new model goes on sale next month and the GS250 petrol starts at £32,995 with the luxury version costing £35,995 and the F Sport version £39,995.
