Each team will be allowed to run just two cars on Fridays, to be manned by either racer or a nominated tester. Given the added running time on the first day of GP weekends, the two-race engine regulations will now only apply to the second day of practice (Saturday) and the day of the race.
Does this mean that the teams will now have to bring four cars to a venue (two with two-race restricted engines for Saturday & Sunday, and two without restrictions for Fridays)?

I'd say multiple engines and aerodynamic pieces. I mean, if the new pieces test well, you'd probably want to use it in the race as well.

Friday free practice will be extended to two 90-minute sessions, from the current two 60-minute format. However, teams will be limited to using two cars in any one session which will be driven by a nominated third driver or the team's regular two race drivers. In another twist, Friday practice will be exempt from the two-engine rules.

At the moment engines must last for two successive Grands Prix and any unscheduled engine changes incur a ten place grid penalty. This has meant that the main drivers have not run much on Fridays to conserve engine mileage. The new rule is designed to fix that problem.

I guess that means two cars, with engines that, while are sealed, can be removed for the friday session, only to be replaced for saturday and sunday.

still seems weird, but okay...
