The INFINITI Q50 (2015-19) 4DR SALOON 3.5H V6 SS 364 EU6 HYBRID PREMIUM EXECUTIVE AUTO7 is a large, four-door premium saloon, aimed at buyers seeking comfort and pace rather than a practical hatchback or SUV. Its petrol-electric hybrid system combines a smooth V6 with electric assistance, giving this Q50 a distinctive alternative to conventional executive cars in the UK saloon market today. mycarcheck.com has recorded just four checks for this exact version, covering one VIN, so its figures are a small snapshot rather than a market-wide guide. Those checks show an average private-sale valuation of £12,900, recorded mileage of 57,000 miles, annual use of 3,000 miles and two previous keepers on average. The Q50 suits commuters and couples wanting a refined motorway car, with a roomy cabin and Premium Executive trim; it is less suited to buyers needing SUV-style access or boot flexibility. Against the BMW 3 Series, Audi A4 and Mercedes-Benz C-Class, its hybrid V6 stands out for performance and character.
