This picture shows that oil hasn't changed much during 2013.
Let's compare to early 2013. WTI has gone up a few dollars since January 1, 2013. Brent is flat right now.

There are a few new EVs coming out during 2014 but not a lot of progress is being made for enough compelling models for the USA car-buyer to choose from. The automakers are all looking at new battery technologies and ways to save money during manufacturing and this should make for a much more dynamic EV marketplace in the late 2015 and early 2016 time period.
The countries absorbing many of the EVs are those which have high incentives. Norway, Denmark, Holland and a few others have given away a large amount of incentives to start to move new EV sales. Norway is very interesting as they do not charge the import car tax which they do charge on ICE vehicles. BMW, Nissan, Tesla and others are taking advantage of that by fast becoming a few of the top cars selling in Norway during the fall of 2013.
