*Figures are provided for comparability purposes; only compare fuel consumption and CO₂ figures with other cars tested to the same test procedures.  Figures may not reflect real life driving results.  Fuel consumption and CO₂ produced varies significantly depending on a number of factors, including the accessories fitted (post-registration), driving style, conditions, speed and vehicle load. 
All mpg figures are tested according to the new World Harmonised Light Vehicle Test Procedure (WLTP), which replaced the New European Driving Cycle test procedure (NEDC).  More information can be found by visiting: The Vehicle Certification Agency website
All CO₂ figures quoted are still tested under the NEDC equivalent until the 1st April 2020. The NEDC figures are used to calculate vehicle tax on first registration.   After 1st April 2020 all CO₂ figures will change to show the WLTP figure. As a result, car tax and recommended 'on the road' prices for new vehicles are subject to change. Please contact your local Lexus Centre for further information.
