Whats a sand cast block? Has Mercedes been using "sand cast" blocks for a while now?I guess we'll know about turbo lag (or lack of) once it becomes available to the automotive journalists like Edmunds, Auto Week, C&D, etc. The engine block is sand cast so it will be pretty strong.
I'm curious how strong the engine block is, cause I know eventually tuners will want to add bigger turbos and just crank out more power. Hopefully it's a really strong block that can handle a ton of power.
