FORMULA One is to return to perhaps the most feared circuit of them all, the 'Green Hell' of the Nürburgring Nordschleife, in September, writes William Scholes.
Well, sort of... Don't expect to see Max Verstappen scampering into the distance on his way to another win, or Lewis Hamilton and Fernando Alonso duelling through the Karussell, or Ferrari botch their strategy yet again.
In fact, there won't be any F1 racing at all. Instead, this will very much be a Red Bull promotional event, one of those festivals of speed and adrenaline that the energy drink company specialises in.
The big draw is that Sebastian Vettel, who won four consecutive world titles with Red Bull, has been lured out of retirement to do a demonstration run in one of his championship-winning cars, the RB7 from 2011. But in an eco-friendly green twist - and Vettel is all about sustainability these days, even investing in sail boats - the car will run on synthetic, carbon-neutral e-fuel.
"Motorsport is my passion," says Vettel. "It's vital to me to demonstrate that racing cars can perform equally well and rapidly on synthetic, such as CO2-neutral fuel. This is no longer a future concept; it's happening right now."
Vettel has a keen sense of F1 history - his party piece is being able to name every world champion in chronological order - and has an impressive collection of important racing cars. He used 'Race Without Trace' carbon-neutral fuels to drive a lap of Silverstone in Nigel Mansell's 1992 'Red Five' championship-winning Williams FW14B at last year's British Grand Prix.
He is due to bring it and another iconic car from his collection - Ayrton Senna's 1993 McLaren MP4/8 - to the Goodwood Festival of Speed in July.

At the Nürburgring in September, Vettel will be joined by Daniel Ricciardo, who is Red Bull's development driver these days. The Australian will take an RB8 from 2012 around the circuit.
Current F1 racer Yuki Tsunoda, who drives for Red Bull's sister outfit Alpha Tauri, is also signed up for the Red Bull Formula Nürburgring extravaganza. He'll not be in a Formula One car, though, as he has been asked to take a Honda NSX GT3 racing car around the track. It's said the 23-year-old will be the youngest driver to tackle the circuit.
“I can’t wait to drive around it in my Honda NSX GT3 Evo, which is an incredible car and a proven race-winning machine at the highest level of GT3 competition," he says.
Tsunoda says he's using his video game console to learn the track: “The Nordschleife is a legendary circuit, I just experienced it on the Gran Turismo video game and already enjoyed it a lot.”
Motorsport fans will be disappointed that Verstappen hasn't been drafted in for a lap or two.
He said he had been banned from taking part - he is cantering his way towards a third world title, so Red Bull perhaps understandably want to keep their prize asset wrapped in as much cotton wool as possible.
Red Bull motorsport supremo Helmut Marko said as much, telling reporters at the last F1 round in Canada that Verstappen couldn't be trusted not to go to the limit.
"We all know Max," said Marko. "First he would have checked what the record was. Of course he wouldn’t want to beat that just by a second...
"Those cars aren’t suited for chasing records. It’s too dangerous."
When Marko talks of danger and a current F1 car not being suited to pursuing a Nürburgring lap record, he will be referring to how the car will have to be set up in a very different way from a normal race weekend.
Modern F1 cars achieve their aerodynamic efficiency in large part because they run so close to the ground, which also requires very stiff suspension. Two things you don't want at the Nürburgring, with its high kerbs and sudden gradient changes, are low ride height and firm, limited suspension travel.
That means the cars that Red Bull is bringing to the Nürburgring will need to have their normal race set ups compromised - expect to see the cars riding a lot higher and given more compliant suspension.
It means a tilt at the current lap record of 5:19.546 - held by Timo Bernhard with a time set in 2018 in a Porsche 919 Hybrid Evo Le Mans racing car - is unlikely to be on the cards in September.
Even so, the chance to see modern F1 machinery tackle the Nürburgring Nordschleife and its 73 corners is sure to be spectacular - and inspire some 'what if…?' thinking about whether a real F1 race would be feasible on the mountain circuit in the 21st century.
