I bought a 450h new 5 years ago. 28 to 32 is the best I can get around town. Sure if I drive at 55mph on a long motorway drive I get very high figures but who wants to drive like that, it feels like driving a golf cart on a motorway. Lexus fuel figure are BS. Read Honest Johns test drive in the motoring section of the Telegraph for verification. A lot of Lexus owners live with the lie because they like the drive so much. But face it, its a 3.5 litre engine, with automatic transmission, and a lot of weight to haul. Ya just won't get better that 28-32 mpg outa any 3.5 litre engine unless its in the body of a VW Golf maybe.
