Under the bonnet sits a 2.0 litre petrol engine that meets Euro 6 emission standards, offering a balanced driving experience that combines performance with modern efficiency. The vehicle is well equipped for daily use, featuring the M Sport Pro Pack and Driving Assistant technology to support the driver on various road types. Practicality is a key strength, as the car offers a large boot space for luggage and shopping, while the sun protection glass adds a touch of comfort for passengers.

Furthermore, its low insurance group rating makes it a sensible choice for those seeking a premium driving experience without the high running costs often associated with similar vehicles.
