Ingolstadt handed Gumpert the 40v version of the 4.2-litre V8 it had previously used to power the S8. He furnished it with two gigantic KKK turbochargers and set about extracting up to 800hp. Around it his team built a latticework of tubular steel, incorporated a carbon tub for two bucket seats and shrouded it all in a fibreglass body that only a blind aerodynamicist could love.
The result weighed less than 1,200kg though and could do almost 225mph even in its 'base' 650hp spec. Equipped with a better power-to-weight ratio than a Ferrari Enzo, it was unquestionably one of the fastest cars in the world at the time. But it was also savage and somewhat crude, and probably not the easiest sell given its rivals. By 2013, the company had gone into liquidation.
That car though is apparently no more, and by the end of 2016 the firm had parted ways with its founder. One might have expected it to falter at this point, but lo and behold, just shy of 12 months later, Apollo Automobil is back with a teaser video and all guns blazing. There is no car just yet, but there is a name: Intensa Emozione - Intense Emotion - or, mercifully, just IE.
If that name doesn't exactly fill you with hope, then there is at least the prospect of new-from-the-ground-up design apparently based on a carbon fibre chassis. We wouldn't be shocked to our cotton socks to see a little Arrow influence left in there - but the LMP1-style fin between the rear wing and engine cover suggests that Apollo has gone to town on it, as does speculation of a naturally-aspirated V12 installed beneath.
We await the official unveiling next week with interest. Until then, there's this shadowy video to watch, and - incredibly - even a classified to peruse if all this talk of Gumpert has you pining for the good old days.
