guys,

quick check, based on UK and Singapore's lexus site, the boot size of the standard IS is 480 litres.

however, the US site says its only 391 liters. 13.8 cu ft (391 L)

Not that i can measure it, which site is correct?

 

I think it depends on the measurement method. In Japan, they use VDA and the boot size for gasoline engine (aka IS250/350) is also 480 L whereas for is300h, the boot size is reduced to 450L by VDA standard. What is being quoted in US is probably the SAE method.
