So far, Hyundai sits on top of the sales charts, with Toyota just behind, and Ford and Renault in third and fourth places. Hyundai's chart-topping performance is primarily being driven by the new Tuscon SUV, which has sold in big numbers - almost 900 have been sold since the start of the month. Part of that is down to pent-up demand from ix35 customers trading in, but an equal number must surely be down to Hyundai's much-publicised decision to launch the Tuscon at a discounted price, with those prices set to rise at the end of this month.
The Toyota Corolla was the second-best selling model, followed by the Ford Fiesta and the Volkswagen Golf. Volkswagen has lost both market share and raw sales in January, but company insiders aren't worried - as they point out, Volkswagen was fourth in the January sales charts last year and still finished 2015 as the best selling brand and with the Golf as best selling car.
Another strong performer was the Renault Kadjar, as the big French crossover actually managed to out-sell its mechanically-identical rival, the Nissan Qashqai, as well as other significant models such as the Skoda Octavia, Ford Mondeo and Opel Astra.
