2012 Lexus LS 460 Fuel Economy

5.0
Fuel Economy

The Lexus LS lineup is made up of some of the most technologically savvy vehicles on the planet--not the least of which is the complex, gas-and-battery LS 600h L hybrid. With all the electronics and innovation, though, the LS sedans still are only about as fuel-efficient as a seven-seat crossover.

The EPA rates the rear-drive LS 460 and its long-wheelbase companion at 16/24 mpg, about what you'd see in Toyota's Highlander ute. All-wheel drive lowers the highway rating by one mile per gallon. The LS 600h L hybrid, meanwhile, earns a rating of 19 mpg city, 23 highway—superb in the class.

In its class it's quite green, but the Lexus LS range is still more competitive with crossovers and SUVs than with efficient large sedans.

And purely from a green perspective, the standard LS 460 is a better pick for carrying five adults in comfort than most full-size sport-utility vehicles. That said, if you can forgo a little interior space, the Mercedes-Benz E350 Bluetec has a clean-diesel engine and enables an even better 33 mpg on the highway.
