 massive, massively powerful 23-speaker. I don't know how you cram 23 speakers into a sedan, but a 23-speaker Mark Levinson surround sound system, which is spectacular, actually. You kind of just want to sit in the car and listen. But as I say, it's not the most powerful of the vehicles by a considerable margin. The base engine has 416 horsepower. It's a 3.5-liter twin-turbo V6.
