You need to spend 45 minutes with the Volkswagen Group’s latest full-length financial press release to realise just how precarious the Volkswagen brand’s situation has become.

There are some bright spots. Between January and March this year, vehicle deliveries across the whole VW Group crept up to 2,508,000 units, a rise of 0.8% on the same period in 2015. And the VW Group now has a handy £19.8 billion in cash in the bank, a massive 25% jump on the same time last year.

But the bad news makes a much longer list. Overall sales revenue fell 3.4% (which VW blames mainly on exchange rate issues), profit margins after tax fell from 7.5% for the whole VW Group to just 6.3% and after-tax profits fell almost 20%, to £1.8bn from £2.24bn.

Despite the massive media bashing over the emissions scandal, the advantage of having a portfolio of brands is shown in the sales performance of the various marques. Audi was up by 4% to nearly 456,000 sales in the first three months of the year.

Skoda was up 4.3% to nearly 277,000 sales, Seat crept up 0.2% to 103,000, Porsche leapt 5% to just short of 56,000 sales and Lamborghini was up 5% to 928 sales, from 884.

Volkswagen sales decrease by 2% in first four months of 2016

(I’m going to divert quickly to Bentley’s situation. The British brand’s sales were down an alarming 30% in the first three months of the year, from 2232 units to just 1554. Profits collapsed from £37 million to a £41m loss. The company must hope that existing Bentley buyers are not switching straight to the Bentayga SUV, because these kinds of direct substitution sales will not grow the brand significantly).

Volkswagen brand sales were down just 1.3%, but dig into the fine detail and VW is showing signs of significant stress. According to the official figures, the VW brand had a sales revenue of £19bn, but VW’s operating profit collapsed from £392m last year to just £55.7m between January and March.

That’s in stark contrast to Audi’s 526,000 global sales and £11bn revenue, which delivered operating profits of £990m. Porsche’s 55,000 sales delivered £682m profits. Even Seat - which sold just 127,000 vehicles in the first three months - made £42m profit.
