What is the best part of a modern auto show? It’s not the constant running from one press release to another. It certainly isn’t fighting your way to the front of the throng to get some blurry photos of the latest sports car. It isn’t even the airport-grade lunches and cheap booze. No, it’s the cutaways. Nowhere else will you find the sheer quantity and quality of mechanical cutaways as an auto show. There are engine cutaways, transmission cutaways, and cutaways of entire vehicles.
