As you might imagine, building a hybrid version of the popular GS performance sedan was no simple task. We started with a completely new hybrid powertrain, featuring a 3.5-liter V6 gasoline engine and a high-output permanent-magnet electric motor—all driving the rear wheels. These two potent forces combine to give the GS Hybrid an incredible 339 horsepower [1] and a zero-to-sixty time of less than 5.5 seconds [1, 2].

In fact, with its powerful electric-drive motor, you can look forward to maximum torque at a moment's notice. So while the GS 450h may have a V6 engine under its hood, it delivers powerful acceleration comparable to a V8. Even more amazing, it manages to accomplish all this while maintaining a combined fuel economy ranking akin to many four-cylinder compact sedans, not to mention a Super Ultra-Low Emission Vehicle (SULEV) rating.

Of course, the GS Hybrid shares the same sleek modern design as the current GS 430, along with a few distinctive touches: a set of exclusive 18-inch light-alloy wheels [3], subtle Hybrid badging on the lower side panels, and a new power meter that replaces the conventional tachometer.

But let's not forget, while it may be a hybrid vehicle, it's first and foremost a Lexus, so you can be certain there will be plenty of luxuries waiting for you inside. Not only that, many of the optional features on the GS 300 and GS 430 will come standard on the GS 450h.

Please keep in mind, this is only a sampling of what the GS Hybrid has to offer. As more information becomes available, we'll be certain to pass it along. Thank you again for subscribing to the Lexus Hybrid Newsletter. If you'd like to read past issues, please feel free to visit our archive page.
