As your car makes a turn the outside wheels need to turn faster to make it. So, since there is an acceleration (and a deceleration in the case of the inside one) I figure there must be a force causing it. What force is that?

friction is the force acting on the body that is the vehicle

Its because the outside wheel follows a larger arc and thus covers more distance. The force is simply the wheel moving over the road.

There’s not necessarily an acceleration on the outside wheel. Any acceleration there is due to the engine. There is a deceleration on the inside wheel due to a combination of axle losses, bearing losses, and friction. Mostly friction to the road. If there were no friction, the wheel would continue rotating at the same rate, but the connection to the vehicle prevents it from running off at its same speed.

It’s really the whole system.
