Porsche Panamera

Porsche today revealed the first official photos of its new four-door grand touring sports car, roughly nine months before its scheduled market launch. Joining the 911, Boxster and Cayman sports cars as well as the sporty Cayenne SUV, the Panamera is Porsche's fourth model series. The designers of the Panamera sought to position their latest offering as a brand-new and truly different model while retaining the defining Porsche look.

McLaren P1 gets an Arctic shakedown (+video)

So McLaren are busy throwing the worst conditions they can at the P1 to make sure it can perform even in the harshest of conditions and be the best driver’s car in the world – even when there’s several feet of ice under its wheels. McLaren has had several XP prototypes of the P1 running round the world’s harshest climates – hot and cold – and have delivered a video of the P1 prototype playing on the ice in the north of Sweden – inside the Arctic Circle – to keep interest in the P1 bubbling along ahead of its dynamic debut in the UK at the Goodwood Festival of Speed in July. Despite its enormous power – 903bhp from a combination of its turbo 3.8 litre V8 and electric motor – the P1 does look composed and capable, even with sub-zero temperatures and a surface that has zero grip.

The nadir for Saab should reasonably be followed by its rapid consignment to the annuls of motoring history, but a tiny glimmer of hope has risen from Saab’s putative investors in China.
