Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 23 - 24 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Well, it isn’t going to be cheap. You’ll be lucky to get 25mpg out of the 3.0 and depreciation isn’t the best. Fortunately it feels like a fairly expensive car.

GS performs badly on the eco front. With an average of 290 g/km CO2 across the range, its emissions are high for an executive saloon. It’s worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs. The range is disappointingly thirsty, averaging 24 mpg.

Lexus is Toyota really trying its hardest to be reliable – the GS feel very well put together and durability and dependability should be first class.
