Here, dressed in sheet metal and under hot show lights, is an engineering feat that promises to set into motion a new phase of interior, safety and powertrain technology. The powertrain, for example, is the most powerful hybrid system ever built, featuring V12 power with V8 fuel economy, a SULEV emission rating and 430 horsepower. We can only imagine what the torque rating will be. Safety features include Toyota’s VDIM technology, with some significant advances, such as three outboard cameras that detect large and small objects, and a dashboard camera that monitors your face and activates a safety sequence should the camera detect that you’re not looking at the road. Interior enhancements include a body temperature reading and NVH that’s so quiet, according to Lexus vice president Bob Carter that you can hear the whirring of gears and gyros doing their work.
