The LS is available in either regular wheelbase, or a long wheelbase version with limousine-like rear accommodations. A powerful 4.6-liter V8 sends power through a computer-controlled eight-speed automatic transmission. The addition of all-wheel drive is new for this year. The ultra-smooth suspension provides a quiet environment to listen to the premium sound system, and the voice-activated navigation system makes sure you arrive at your destination. Safety features include eight standard air bags, ABS, electronic brake assist, ESP, adaptive front lighting that turns corners, and tire pressure monitoring.
