Finding comparable vehicles to the 2010 Lexus RX 450h isn't an easy task, but two German SUVs and a downscale Toyota come closest to the Lexus' fuel economy and interior room.
The Mercedes-Benz ML320 CDI sports that maker's BlueTEC diesel engine and gets highway fuel economy in the mid-20s, while offering a plush and expensive five-seat cabin.
The coming VW Touareg diesel is similar in mission to the Benz, minus the coveted badge and brand name; those wanting a slightly sprightlier driving feel might also like the Audi Q7, which late in the 2009 model year comes in a fuel-efficient TDI version.
Toyota's own Highlander Hybrid is another alternative; it's substantially cheaper than the new Lexus hybrid, while offering a similar powertrain and additional seating for two more passengers—with blocky, unrefined looks and loose, unengaging handling.
