The 82nd Geneva motor show threw open its doors to the world's press on Tuesday and it didn't fail to impress, with world debuts from Ferrari, Lamborghini and more.
Best in show will be closely fought between the two Italian thoroughbreds, with Ferrari revealing the all-new F12 Berlinetta and Lamborghini surprising everyone with the dramatic, one-off Aventador J.
Not to be outdone by the Italian stablemates, Infiniti showed off the Emerg-E, which is powered by two electric motors and a small three-cylinder petrol engine. Combined, the motors and engine can propel the two-seater sports car to 60mph is just four seconds.
Meanwhile, the German powerhouses Mercedes and Porsche used Geneva to reveal the new SL 65 AMG and Boxter respectively - both offering significant weight savings over their predecessors. Elsewhere at the show, Land Rover officially announced the Range Rover Evoque convertible. While still a concept at the moment, the car could get the green light for production in just a few weeks' time.
Lamborghini Aventador J
The J is a nod to the Miura Jota, which Lamborghini produced in the 1970s, as well as - more obscurely - appendix J of the FIA motor sport rule book. Although why Lamborghini has chosen to make this reference could be anyone's guess.
The Aventador's striking vertical doors remain and there is a striking divide in the cockpit, separating driver and passenger, who both sit very low down in the car.
Lamborghini stunned visitors to the Geneva motor show with the Aventador J. Lamborghini describes the Aventador J, which sits just 1.1 metres off the ground, as "extremely open" - so they should, as the car has no windscreen, roof or windows.
The Italian manufacturer has stated that only one Aventador J will be made - but it is road legal and sold to one very lucky individual. We just hope that he has a good coat.
Infiniti Emerg-E Concept
The two-seater sports car by Infiniti is driven by two electric motors powered by lithium-ion battery pack, as well as a small three-cylinder petrol engine, combining to produce 402bhp.
Infiniti says the Emerg-E can accelerate from 0-62mph (100kph) in a supercar-rivalling time of 4 seconds and will run for 30 miles on electric power alone.
Ferrari F12 Berlinetta
One of the undisputed highlights of the show is the all-new Ferrari F12 Berlinetta. With its long nose, aggressive front end and muscular haunches, the F12 looks stunning.
Packing a 6.3-litre V12 producing 730bhp, it is the most powerful Ferrari ever produced,and can sprint to 60mph in 3.1 seconds.
Despite the impressive performance, the F12 produces 30 percent less emissions and offers 30 percent better economy than the 599, which it replaces.
Mercedes SL 63 AMG
Mercedes-Benz debuted the SL 63 AMG at Geneva this week, taking a lot of styling cues from the SLS supercar and the more compact SLK roadster.
The new SL is an incredible 125kg lighter than the old outgoing model, meaning that performance and handling will be much improved. With the optional AMG Performance Pack, the SL's twin turbocharged engine produces 564bhp
Porsche has revealed the all-new 2012 Boxster, boasting an ultra- light aluminium body and more agile design with "purposeful" styling, new engines and "significantly enhanced" driving dynamics.
With a dramatically reduced weight, longer wheelbase, widened track and larger wheels, the 2012 Boxster and Boxster S take Porsche's famous mid-engined sports car into a new era.
Power has increased from the out-going model and so has acceleration, with the new Boxster reaching 60mph in 5.7 seconds compared with 5.9 for the older generation; the Boxster S now hits 60mph in five seconds dead, 0.3 seconds faster than the old model.
