The updated Infinity Q50 was revealed to the general public at the International Spring Geneva Motor Show in March 2017. The model is the first planned and not very deep restyling. The novelty has stylish elongated headlights with lensed optics and LED “eyelashes”. The radiator grille is made in the corporate style and flaunts the manufacturer’s logo.

It consists of many diagonal intersecting ribs and chrome edging along the contour. Below, on the front bumper, there is a rectangular air intake, also covered with a plastic mesh. On the sides of it, you can see special grooves with round fog lamps and LED lights. All in all, the car has received several minor cosmetic changes and has not lost its family traits.

The mid-size sedan Infiniti Q50 is one of the most striking and driving cars of the premium Japanese brand. It is not surprising that this model is popular with women who do not just strive to stand out but are looking for a practical and safe car with a sporty character. We brought one of the most advanced performances of the “fifty” to a confrontation with Eva Motornaya – a sedan in the Sport configuration.

Such cars, in addition to generous equipment, are distinguished by aggressive bumpers, denser suspension, reinforced brakes and proprietary DAS (Direct Adaptive Steering) steering, in which there is no mechanical connection between the wheels and the steering wheel, and the turn is carried out by order of the electronic control unit.

Today the Q50 is the most popular model of the brand in the world market, and they are not joking with such things. So the Japanese chose the path of slow evolution – and they did the right thing.

A little over a year ago, the second generation of the Direct Adaptive Steering system was presented, DAS 2.0 – the famous steering “by wire”, along with it a number of technical innovations were proposed, and now the time has come for aesthetic changes. Neat and careful, so that only sophisticated Infiniti philes will be able to immediately notice the changes, but enough for us to become interested in the new product and take it for a test.
