Retaining its position as the fastest-growing performance brand in the UK, AMG reported a 75% rise in registrations for January.
Contributing to this high-performance result was the C 63 AMG Estate, the registrations for which rose by 125%.
As the weather conditions deteriorated, registrations of the M-Class rose by 386.3% compared to January 2012 – securing a substantial 14.4% share of the market segment.
The new A-Class captured a 6.2% share of its segment and it will be joined by the CLA four-door coupé in June.
Likewise, Mercedes-Benz made its debut in the small van market as the first examples of the new Citan were registered ahead of its market introduction in the coming months.
Marcus Breitschwerdt, president and CEO of Mercedes-Benz UK, said: “This promises to be an exciting year for us.
“We have advanced and desirable new models being added to our range – the new A-Class made its market debut this year – and we’re looking forward to the arrival of the new CLA and the new E-Class.
"This is bolstered by great new products from our Commercial Vehicles operation – including the new Citan – adding to the surprises in store for 2013."
