Although it doesn't look a world different from the later evolutions of the original Koenigsegg CC the new Agera raises the Swedish supercar builder's game to a whole new level.
Debuting in production form the Speed Racer liveried R version - complete with ski roof-box - puts out a stunning 1,115hp on biofuel, Koenigsegg reckoning it's on for a Veyron humbling 273mph on a good day. Truly stunning.
Koenigsegg Agera R
With the 458 Italia comfortably setting the benchmark by which all other supercars are judged, Ferrari has been given the freedom to do something a bit different. The four-wheel drive, four-seat FF is just that.
A replacement for the 612 Scaglietti, the 660hp FF is a wholly different proposition from its mad shooting brake styling to its all-wheel drive chassis. Luxurious and spacious it may be but it'll still do 0-62mph in 3.7 seconds and 208mph.
Monstrously fast and mega hardcore, the Gumpert Apollo is a hell of a piece of kit but, let's face it, blessed with a face only its mother could love. For this more mainstream Tornante, Gumpert has wisely enlisted help.
Who better than legendary coachbuilders Touring Superleggera, lightweight pioneers behind classic Astons and Ferraris of old. Thus, Italian style and German engineering combine to spectacular effect, with Gumpert's 700hp brutalism toned back slightly for a (relatively) more relaxed drive.
The Zonda proved former Lamborghini man Horacio Pagani's mastery of carbon fibre as an art form so expectation was high for its replacement, the Huayra. Confusion still reigns about how to pronounce the name though!
Everyone agrees the million-Euro, 700hp, Mercedes-powered Pagani is an absolute stunner, mixing fabulous design with technical trickery - like the four moveable flaps controlling downforce and weight transfer under braking.
Lamborghini Aventador LP700-4
The honest truth? In pictures the Aventador LP700-4 looked like it might be a little too conservative for a flagship Lamborghini. No such worries having seen it!
In the flesh the Aventador is everything a Lambo should be - extravagant, exciting, aggressive and just a teeny bit mad. Given the tech at £200K it seems a relative bargain too!
MTM Audi R8 V10 Biturbo
Chrome wrap? Nope, MTM has actually got the wet and dry out and rubbed this R8's paintwork down to the bare aluminium and polished it for stunning effect. It took them 700 man hours but the result is fabulous.
As is the replacement of the regular 4.2-litre V8 with the 5.0-litre, twin turbo V10 from an Audi RS6. Tuned to 777hp it humbles the 525hp of the standard R8 V10 and unleashes the monster within, capable of 215mph.
Aston Martin Vantage S
The Aston Martin Virage also here at the Geneva Motor Show 2011 is a tasty piece of kit. But the 'baby' Vantage has also come in for attention, and though the changes are relatively detailed, on paper it promises to be an absolute stormer to drive.
There's a new seven-speed automated manual gearbox for starters, this giving a much more aggressive shift and raw feel than a dual-clutch transmission. 10hp extra, a faster steering rack and bulked up bodykit complete the Vantage S package.
Alfa 4C Concept
With all these 1000hp, 200mph-plus megacars around it's nice to see Alfa Romeo reminding everyone that the joy of driving a sports car isn't all about horsepower figures and chest-beating bragging rights.
Promised for production, the 4C will weigh less than 850kg and, as a result, needs nothing more than a 235hp 1750cc turbo engine (a significant number for Alfa fans) for a sub-5.0 seconds 0-62mph time and driving fun to match the stunning looks.
Brabus SLS 700 Biturbo
Brabus had teased with a wide-body styling conversion for the SLS. But we all know the Mercedes tuner is capable of more than that and, sure enough, the engineers have been busy unleashing more power from the 6.2-litre V8.
In the old days Brabus would have bored it out and gone big, but turbos are the way forward now, two of them attached to the V8 for a mighty 700hp and a top speed of 213mph.
Aiming to put Spain on the supercar map, newcomer GTA faces an uphill struggle making a noise for itself at a show with new cars from Ferrari, Lamborghini, Pagani and others. But the Spano does a good job of standing out from the supercar crowd.
It looks distinctive for a start and features like a glass roof that switches from clear to opaque are neat, ditto the carbon fibre construction and self-built 8.3-litre V10 with a mighty 820hp. GTA claims 0-62 in 2.9 seconds and a 217mph top speed.
