Koenigsegg Agera news - Geneva show: 898bhp Koenigsegg Agera - 2010

Koenigseggs: too slow, too underpowered, too boring to look at.

Until now, and this. This is the Agera, the latest hypercar from everyone's favourite mad Swedes.

Though Koenigsegg would love you to believe so, it isn't quite all-new, but instead a heavily modified, powered-up and angrified version of the outgoing CCX.

The Agera puts out - get ready - a deranged 898bhp from a 4.7-litre V8. Add in a not-immodest 811lb ft of torque and you're looking at a thing that can dispatch 62mph in 3.1 seconds and 124mph in under nine seconds before topping out at something very close to 250mph. Those are mad, mad numbers.

But our favourite number is a slightly more subtle one: 72kg. That's how much the Agera's entire carbon fibre chassis weighs, which is less than many normal-sized humans - most of whom are not, admittedly, made of carbon fibre.

The Agera gets adjustable suspension, a removable hard-top and bodywork rendered entirely in carbon fibre and Kevlar. Thanks to its flat underbody and many clever wings, it produces over 300kg of downforce at 155mph.

How much will it cost? Er, lots. We can't imagine that'll get in the way of Koenigsegg's desire to sell around 20 Ageras each year, though.

They say their order books are open right now at the Geneva show. Better get your man to put in a phone call quicksharp if you want one of these hypercars.

Actually, we're pretty sure Koenigseggs have just smashed right out the top end of the ‘hypercar' description. We need a new word.

Ultracars? Megacars? Suggestions please...
