How can a Formula 1 team spend nearly £310million on running two cars for a season - especially when that's not even taking engine development costs into consideration? It's a question that must surely be giving a lot of people in the championship food for thought, not least Liberty, which is trying to get teams to reduce spending and make the business a profitable one for everybody.
That figure, you may not be surprised to know, relates to what Mercedes spent solely on its race team to win the 2017 drivers' and constructors' world championships. However, it's important to stress that only a small proportion of that - around £60m - was actually spent by parent company Daimler AG.
The rest came from sponsorship and income from the commercial rights holder. And the latter number is in turn related not just to Mercedes' ongoing success, but also to what was a record profit for the F1 business in 2016, the last year under the stewardship of Bernie Ecclestone. In other words, Mercedes earned a big slice of what was a bigger pie.
