Sales of the Fiat 500X fell by two thirds over 2016, prompting Fiat to usher in a series of tweaks to the small SUV for 2018.
In 2016, the brand sold 14,224 examples of the model, but this tumbled to 4814 in 2017, a collapse of 66%.
In response, Fiat has clipped the 1.3-litre Multijet diesel engine from the 500X line-up, leaving four engines remaining: the 1.4-litre Multiair and 1.6-litre E-torQ petrols and the 1.6-litre and 2.0-litre Multijet diesels.
Prices have been cut across the range, with the range-topping 2.0-litre Cross model taking a £1400 drop. An increase of £120 has been applied to bottom-rung Pop trim, however.
In addition, the higher-spec Lounge and Cross Plus trim levels have been pruned from the line-up, leaving Pop, Pop Star, Mirror and Cross.
Cross brings more rugged styling and the range-topping 2.0-litre engine.
Apple CarPlay and Android Auto smartphone mirroring are now standard across the board, while the 5.0in infotainment touchscreen has been upgraded to a 7.0in unit.
Explaining the cuts, a Fiat spokesman said: “The 2018 500X range includes greater connectivity as standard. Pricing and trim levels across the range have been streamlined to simplify the offering for customers.”
Last year's sales drop was unexpected for Fiat; the 500X is the only SUV in the brand's line-up in the midst of an SUV market boom, while the 500 continues to sell strongly despite a mild Europe-wide decline in the city car market.
It's also likely that the 500X range has been trimmed to accommodate the upcoming WLTP fuel economy and emissions testing procedure, under which every spec of a model must be separately tested.
