Start GS450h , and you will see there is no tachometer , power and charging only a speedo next measure . Turn the Drive Mode button for the sport , and measure the power disappears and turns into a tach , number and all . In addition to getting a tachometer , turn to sports to send more water to electric drive motors to increase its role in the acceleration - the acceleration of our tests are conducted in sport mode .

The system uses two electric motors , one under the hood which mainly handles charging and the other in the rear differential to help drive the wheels ; the latter works in concert with Atkinson - Cycle V - 6 to produce 338 hp ( 32 more than the rest of the lineup GS ) . Course , direct and port injection V - 6 making 286 hp , 20 less than the 3.5 - liter V - 6 in the GS350 .

Drive it like a Prius , and GS450h handily beat the fuel economy of gas - only GS models . In our hands , it achieves 27 mpg in a mix of highway and city driving . More careful driver should be able to match the EPA fuel economy ratings of 29 mpg city and 34 highway .

Despite the extra power of the hybrid system , we tested it on is still the slowest member of the new GS lineup , turning in a 0 - to- 60 - mph of 5.7 seconds . The GS350 and GS350 F Sport AWD we have tested a little faster to 60 , at 5.5 and 5.6 seconds . Passing power in hybrid better than the gas - only version , however , such as electric motors provide the impetus turbolike once GS450h is up to speed .
