Now 20 years since the Lexus GS model debuted as an inline six-cylinder sedan, the midsize luxury line has expanded to include a V8 and -- beginning in 2006 -- a hybrid option.
The current GS 450h features a second-generation hybrid system: a 3.5-liter V6 paired with two electric motors and a continuously variable transmission. With 338 horsepower on tap, the GS 450h can reach 60 mph in 5.6 seconds. Fuel economy is good, though not exceptional: 29 mpg city and 34 mpg highway.
