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.
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.
As well as the T80, Mercedes is also bringing some as yet unconfirmed Silver Arrows racers from 1934 to 1954.
These will be complemented on the hill by a 21st-century sibling, the 2016 Mercedes-AMG Petronas Motorsport F1 W07 Hybrid, driven by Valtteri Bottas on the Sunday and test driver George Russell the day before.
But that's not all. Alongside modern Mercedes and AMG road cars – and the Mercedes-AMG Project ONE hypercar – will be two other notable three-pointed stars.
The Mercedes-Benz Classic team is also bringing the Rudolf Uhlenhaut-designed 300SLR from 1955, plus the 1998 CLK LM, pictured here with Klaus Ludwig at the wheel.
So there's plenty for Mercedes fans at this year's Goodwood Festival of Speed. Indeed, if Stuttgart metal really floats your boat, the event's usually striking central display this year commemorates Porsche's 70th – which you can do yourself with C&SC's Porsche Greatest Hits.
