Lamborghini Egoista revealed at Lamborghini’s 50th Anniversary celebrations UPDATED

The Lamborghini Egoista (which translate as the Lamborghini ‘Selfish’) gets its name because it is designed as a single seater, purely for the pleasure of the driver. Designed by Walter De Silva, the Egoista sports dramatic styling that is said to be inspired by the Apache helicopter (and isn’t entirely successful – the Apache looks better) and extensively uses carbon fibre with a canopy that can be removed for real single-seat fresh air thrills. Power comes from the Gallardo’s 5.2 litre V10, although so far all Lamborghini has done is release a single photo of the Egoista (above), so we don’t yet know whether the Egoista will be a one-off special like the Aventador J, a short run at silly prices like the Veneno or just a concept that will never see the light of day again.

Infiniti-designed Santa's sleigh (2010)

Today's sleighs are courtesy of Infiniti. The design team in Japan have sketched out a couple of Infiniti sledges for Father Christmas to deliver his presents across the globe in imperious style. The first sleigh looks like an Essence supercar concept meets an FX crossover - from that long snout and high-mounted, wedgy headlamps to the complex, textured surfaces, sliced and diced by a laser-pointer's worth of sloping lines flying off at all sorts of angles.
