Koenigsegg steal the limelight at Geneva with the Regera, a "1500hp plus" hybrid megacar. Headline figures are 0-400kmh in under 20 seconds, on the tyre slip limit up to 270kmh, 1100hp 5.0l V8 and maximum 700hp electric motors. Power is delivered via a system to optimise performance and the claimed figures will leave anything else in its dust.
