For anyone thats interested, the chief engineer for the ZR2 is going to be talking about the truck & answering questions this afternoon on Autoline After Hours.
Show goes live at 3pm (eastern) & can be watched
here. You can watch it later or listen to it as a podcast as well.
If you've got any questions to ask, send it to Autoline's viewer mail (address is on their website somewhere). They also take phone calls (pre-recorded) if thats more your style.
