Mercedes-Benz has revealed that its incredible, one-off 3000hp racer is coming to this year's Goodwood Festival of Speed (12-15 July).
And the jaw-dropping numbers just keep on coming with the 1939 T80.
This six-wheel, triple-axle single-seater is eight metres long, three metres wide and powered by a colossal 44.5-litre V12 aeroengine.
Inspired by Hans Stuck in 1936, the T80 was designed by Ferdinand Porsche to set a new land-speed world record.
And here is that massive 44.5-litre, twelve-cylinder engine
However, as you may have guessed, history overtook it.
Not content solely with its Grand Prix wins, Mercedes was on a world-record hunt in 1939.
Rudolf Caracciola broke a number of records on a stretch of motorway near Dessau, then on 12 October the T80 completed its first run on a chassis dynamometer.
But the outbreak of WW2 meant the project progressed no further.
Silver Arrows will also be at Goodwood – here's the W165 at the 1939 Grand Prix of Tripoli, the only race it entered (and it won)
