The 2018 Lexus GS 450h F-Sport Sedan fares well in the midsize sedan segment. Adding $16,420 to the price of the standard gasoline variant, the GS 450h hybrid carries a base price of MSRP of $68,680 and is offered in a single trim. The engine on service here is a familiar 3.5L V6 supported by an 18.1 kWh battery pack. Mated to a continuously variable automatic transmission, it makes 338 horsepower and 369 lb-ft of torque. The combined fuel economy improves from 22 MPG on the standard gasoline variant to 31 MPG on the hybrid variant, making the increase in sticker price worth it. Performance of the GS 450h hybrid also improves here, with the car accelerating from 0 to 60 mph in 5.6 seconds. Lexus offers the same 8 colors for the GS 450h hybrid. The GS 450h mainly competes against the inexpensive Acura RLX Hybrid Sedan and the Infiniti Q70 Hybrid Sedan.
