Lexus IS 300h News | RMB Automotive


Lexus’ IS 300h has been recognised as the most fuel-efficient in its class by What Car? magazine, beating the hybrid version of Mercedes’ C-Class to the title.

The motoring publication measured real-world MPG figures for the IS 300h and various other luxury saloons in the class to gain an accurate understanding of each car’s true efficiency. This test differs from the official mpg figure, which is based on government laboratory tests.

In total, 14 executive models were assessed by What Car? but none could compete with the IS’ figure of 59.6mpg, including the Mercedes C300 Hybrid and vehicles from Audi and BMW. The automotive magazine praised the Lexus as a “compelling company car option”, and emphasised its low running costs for business users when compared to rival diesels. The manufacturer was also commended for its superb reliability record and the service excellence delivered by partner dealerships.

Helping the IS 300h to its title is a 2.5-litre 178bhp direct injection petrol engine which links with a high-output electric motor. The Japanese carmaker calls this system Lexus Hybrid Drive, and it allows the driver to select EV (Electric Vehicle) mode to use no petrol and therefore emit no CO2. In hybrid mode the unit releases just 99g/km as it returns satisfying real-world fuel economy.

Despite these impressive efficiency and emissions output, the IS 300h is still great fun to drive. The Drive Mode Select dial includes a Sport mode which instantly enhances the responsiveness of the drivetrain. At its quickest the saloon will sprint from 0-60mph in around 8.3 seconds, and the inclusion of Active Sound Control gives the powertrain a sophisticated engine note.
