The referendum result, in which almost 52 percent of the U.K. elected to leave the EU, has led to political and economic uncertainty and created questions about how it will affect manufacturing operations in the U.K.
"While it is clear there will now be a period of uncertainty, there will be no immediate change to our operations in the U.K," a spokesperson for car-maker Rolls Royce Motor Cars told CNBC via email.
"We know that many of the relevant conditions for supplying the European market will have to be re-negotiated, but of course we cannot say what this means for our U.K. operations until those future regulatory and legislative arrangements are agreed."
As a result of uncertainty, market analysts have revised down their expectations for the autos market. For instance, IHS Automotive now expects muted growth of light vehicle production between 2016 and 2018.
"A more significant reduction is seen in 2017, when we expect output at 92.331 million units against 93.515 million units in our June forecast," the company said in a press release last week.
"The reduction in output is 1.184 million units and reflects year-on-year growth of 1 percent compared to 2.1 percent anticipated in the current forecast."
