Overview
Cars like the 2018 Lexus GS 450h Sedan might not be able to give you the direct benefits one might expect from its hybrid powertrain. However, its usefulness must not be overlooked. The GS 450h uses its 3.5-liter gasoline V6 engine and a large electric motor to produce 338 horsepower and 254 lb-ft of torque. This gives the GS 450h a 0-60 of 5.6 seconds. The hybrid engine here is to support the gasoline engine to boost performance and offer slightly better fuel economy than what a single gasoline engine would be capable of. That said, the GS 450h achieves a combined fuel economy of 31 MPG. As part of the midsize sedan, the GS 450h competes with the Acura RLX Hybrid, the Mercedes Benz E400 Hybrid, and the BMW 5 Series Hybrid. It offers one trim, starting at an MSRP of $63,635
