After more than a decade of playing catch up to BMW, Mercedes is finally eclipsing its biggest rival – last year, it sold 2.2 million vehicles, making it the world's best-selling premium car maker.

Volume isn’t everything, though – net profit was just under €8.6 billion for 2016, which is a modest growth of 1% over 2015. BMW hasn’t announced its full-year profits yet, but based on its profit of €5.4bn in the first nine months of 2016, it doesn’t seem likely it’ll match Mercedes.

So what has helped Mercedes along the way? Well, firstly, its core offering is vastly improved on recent years. Buyers should now consider a C-Class over an Audi A4 or BMW 3 Series, which certainly wasn’t the case in previous generations.

Talking at today’s announcement on 2016’s financial results, boss Dr Dieter Zetsche said SUVs make up 30% of Mercedes' sales. That’s no surprise when you look at industry trends, and that growth for Mercedes will only accelerate. It introduced the GLC Coupé late last year and we already know that a GLB model sitting between the GLA and GLC is on its way.

Other than that, Zetsche said Smart had played a role – sales increased by 19% to a new record high of 144,400 units. “Sales were especially popular in China, rising by 70% compared with 2015,” he commented.

One jewel in Mercedes' crown is AMG, which Zetsche described as a “major sales driver”. The performance brand sold 100,000 cars in 2016, an increase of 44%. And AMG boss Tobias Moers told Autocar recently that he expects that figure to grow considerably this year, too, even if it doesn’t quite match that rate of growth. Zetsche also mentioned AMG's highly anticipated hypercar, which will use Formula 1-derived hybrid drive technology. “This offers a preview of things to come at AMG. We will define performance in the era of electric drive,” he said.

Zetsche on Trump and Brexit

However, despite Mercedes’ bright outlook, there were plenty of questions posed at today’s conference about market volatility around the world. Zetsche - like many manufacturer bosses Autocar has spoken to recently – was reluctant to comment on President Donald Trump or Brexit and their possible effects on business.

“Times certainly seem to be more volatile,” he said. “When it comes to Brexit, nobody can tell what this will mean for trade flows and trade relations. This is merely speculative at this point and that is why we don’t want to speculate. Our task is to work with the general conditions imposed by politicians and work to make it as successful as possible.”

When asked about Trump and his plans, Zetsche dodged most questions, but did say: “We prepare for things once we know the facts at hand. We, at Daimler [Mercedes’ parent company] are convinced that the entire world will profit from free trade. We have always done and will always do so, and we will try to take measures to facilitate free trade.”

EVs will cost same as petrol within a decade

Naturally, there was plenty of talk about connectivity, autonomy, shared services (or mobility) and electric plans, which Mercedes labels ‘CASE’. Despite Mercedes’ claims on being at the forefront of that, with millions of miles of autonomous testing and its Car2Go car-sharing programme – plus a new co-operation with Uber -  plenty of other car makers claim the same. Zetsche said: “We intend to occupy a leading position in all of these fields. We will continue to focus on the things that have made us so successful today. We’ve also identified several fundamental changes which are taking place in the automotive industry,” he added, referring to those CASE elements.
