This powerful 5.0-liter engine features both port and direct fuel injection. In addition, this V8 is paired with a high-output electric-drive motor, giving the LS 600h L a total 438 system horsepower (Ratings achieved using the required premium unleaded gasoline with an octane rating of 91 or higher. If premium fuel is not used, performance will decrease, and a 0-to-60 time of a mere 5.5 seconds (Performance figures are for comparison only and were obtained with prototype vehicles by professional drivers using special safety equipment and procedures. Do not attempt)

Direct Injection

With this direct injection system, a more effective mixture of air and fuel is attained. This boosts overall power. Plus, with the extra control over the air/fuel ratio, mileage is also improved. This system, in conjunction with traditional port injection, helps to achieve a smoother running engine and improved drivability.

EV mode (CAUTION! When driving a hybrid vehicle, pay special attention to the area around the vehicle. Because there is little vehicle noise in electric-only mode, pedestrians, people riding bicycles or other people and vehicles in the area may not be aware of the vehicle starting off or approaching them, so take extra care while driving) allows the vehicle to operate at low speeds on the electric motor alone and will not use the gasoline engine. This technology has two major benefits: low noise and zero emissions. Maximum driving distance for EV mode is approximately one-half of a mile, depending on battery charge and driving conditions.

Braking

The braking system on the LS 600h L features four-wheel ventilated disc brakes and Electronic Controlled Braking (ECB), which is a vital component of the Vehicle Dynamics Integrated Management (VDIM) system. A sensor detects the brake-pedal position and activates the master cylinder accordingly. Both the front and rear brakes are ventilated to help provide superior stopping performance.

Performance drivers may wish to consider the available high-friction brake pads (available with the Active Power Stabilizer Suspension System). They yield a higher coefficient of friction on the rotors to help provide better braking response.

The LS 600h L also includes a brake hold system that, when activated, helps hold the vehicle in place after a complete stop—without requiring the driver to keep their foot on the brake pedal. This helps prevent the LS 600h L from creeping forward or backward when stopped.

Also noteworthy is the electronic parking brake, which is activated the moment the vehicle is placed in Park. As soon as the driver shifts into any other gear, the parking brake is automatically released.
