The Lexus GS450h is a wolf in sheeps clothing. The performance is outstanding and the linear acceleration due to the hybrid motor feeding in power leaves all but the exotica behind when accelerating above 50mph. Despite car test comments (based on early models)the ride is excellent but you need to dial it into sports mode for good handling. Fuel consumption depends on driving style but 34 -35 mpg (UK) is achieved cruising along major roads and motorways - amazing for a 3.5 litre car. In busy towns the electric motor takes over the car returns a fuel comsumption which is outstanding for such a large car. It is general urban motoring that leads to lower mpg. The only drawback I see is a small boot and no drop down rear seats. Reliability is excellent but to be expected from Lexus, customer service is second to none.

Nice car if you're made of money and want to kid yourself you're being environmentally conscious!
