Import/export tariffs and duties on top of European regulations that would apply on countries without a proper trade agreement. Just a few weeks ago Toyota warned on 10% duties on UK-built cars. But this is just the tip of the spear.Why? (Not doubting, just want to understand the mechanic in this particular case.)
Factories across Europe have to compete with each other in order to produce new models or keep the ones already in place. It isn't just salaries, but supporting partners in the region and the capacity to expand if necessary. This is a little known fact that is the cause of much bitterness in the industry. Japanese companies have already frozen investment at their UK plants due to the sheer uncertainty of the situation, which means that money will go elsewhere, propping factories in other regions and making Sunderland and other British locations less competitive. And this won't be just a 2016 thing. Nissan, Honda and Toyota will be extremely wary of making significant new investments in the UK for several years (at very least until the UK has exited the EU and the economic factors have stabilised), specially when they already have competitive factories in the continent that are more than willing to take in new models.
Sooner than later mainland factories will take some volume or even entire model lines, British parts providers (which are absolutely critical and can be used to measure the health of the automotive industry of a given country, since they are usually the fist to fall due to reduced margins and increased financial exposure) will start to fold/reduce their numbers due to the decrease in orders and the British automotive industry won't be competitive anymore. And Sunderland is a privileged location as it "only" exports 55% of its total production, which includes several models. It will be bled out of them over time. Other factories, specially those hosting a single model, exporting most of their output or simply taking most components from abroad will be even less fortunate. General Motors factory in Ellesmere Port is super fucked.
Financial and trade uncertainty in the British car industry is expected to last well over five years. It may take up to eight years before the climate allows for new investment in large quantities, meaning that trade with the EU is not severely impacted. Meanwhile, other locations will receive funding and models currently asigned to the UK as they become more competitive and trade restrictions take their toll. The entire European industry is going to go through some difficult times since the UK's market will contract (this is not an "if"), but the UK is going to take the most damage since its automotive renaissance was built on the back of Japanese companies, which are now incredibly vulnerable. Others such as GM aren't even that lucky.
