Car industry is in a pickle, caused by most governments. Gave us cool tax Incentives us to all go buy Diesels and now they are punishing us. Car's like X-Trails and Qashqui I would imagine be bought as Diesels, due to size to weight ratio and what engine would give you better MPG etc. Now you might not get the tax breaks etc, sod buying that, go back to Unleaded, if you go unleaded the weight would muller the MPG, so get a saloon or something.
I reckon we've got about 10-15 years left of new cars being the old fashioned Combustion Engine. Also Japanese dominance of the car market is slowly fading out, German cars are overtaking them in terms of tech, self drive, etc etc. God most Japanese cars have German ADAS tech in them (Bosch, Continental and ZF-TRW)
I believe Nissan have been looking to move manufacturing of the Qashqui back to Japan for awhile now, they did drop that Brexit bit in as after sentence, main reasons due to plummeting Diesel sales, which these odd SUV crossover cars are mainly bought as.
