Ken Block’s Gymkhana Five: The Streets of San Francisco

Everyone’s favourite Hooner and Drifter – Ken Block – is back with Gymkhana Five, a mad blat round the streets of San Francisco. If you want a car video full of tyre smoke, drifting and downright hooning madness, Ken Block’s your man. This time, with Gymkhana 5, the good Mr Block takes his 650hp Ford Fiesta on a blat round every familiar landmark in the streets of San Francisco, and manages to do it much more impressively than Karl Malden or Michael Douglas ever did.

Aspid GT-21 Invictus revealed – sort of

Aspid – the Spanish supercar maker which was IFR Aspid – has revealed the first images, and video, of the new Aspid GT-21 Invictus. IFR Aspid made the Caterham-esque – and rather bonkers – Aspid SuperSport, but after a change of name to just ‘Aspid’ they teased a new car back in May, which looked to be more mainstream. That tease arrives as the Aspid GT-21 Invictus, which takes the starting point of the very ‘open’ SuperSport and clothes it in a new body that turns it in to more of a GT car – even if it still gets open front wheels.

Porsche 911 Carrera 4 (2012) first official pictures

Porsche has a new four-wheel drive - but it's not the Macan crossover, or an SUV of any description.

It's also lost around 65kg compared with the old 997 Carrera 4, and Porsche claims it's a good deal faster too.
