A super-frugal Lexus GS hybrid could carry a GS250 badge
Lexus engineers are working on a super-frugal version of the new GS Hybrid according to company sources. Although the new 3.5-litre V6 GS450h has a CO2 rating, depending on specification, of between 137g/km and 141g/km, Lexus bosses recognise that the executive car market in Europe is increasingly dominated by four-cylinder diesel-engined models.
The new hybrid model will arrive in the second-half of 2013 and is likely to use a downsized six-cylinder petrol engine. Referring to the new four-cylinder Audi A8 hybrid, Yoshihiko Kanamori, chief engineer said that the need for in-cabin noise cancellation to improve refinement in the German car was one of the reasons that a Lexus GS ‘could never have a four-cylinder engine.’
Although the Japanese company would not reveal more about the new GS Hybrid (potentially badged GS350h) it is possible that it will use a version of the 204bhp 2.5-litre V6 engine that is fitted to the new GS250. Hitting a CO2 figure of 119g/km - matching the BMW 520ed - is the likely aim of the new model. It would, though, also offer higher performance than the four-pot BMW.
