Porsche Panamera Hybrid: Geneva Reveal

The Porsche Panamera Hybrid (click for bigger image) We’ve got to say, the news that the Porsche Panamera Hybrid (strictly speaking, the Porsche Panamera S Hybrid) is going to debut at the Geneva Motor Show in a couple of weeks time isn’t exactly a shock. After all, Porsche has made no secret of its plans to stick Hybrid gubbins in the Panamera; CO2 targets, and all that guff. But Porsche seems to think it is a surprise (unless they really have a surprise and are planning on revealing another Porsche hybrid altogether much sooner than we expected) as the press release we got in from Porsche has the enigmatic little tease of a headline – ‘Porsche: Hybrid world premiere’.

Aston Martin outlines Centenary celebrations

Aston Martin celebrates its centenary year in 2013 and has outlined plans to celebrate 100 years of Aston Martin. Officially, Aston Martin was founded in 1913 – although it was not until after the first world war ended that they actually started proper production – and with 2013 marking 100 years of Aston Martin there are celebrations planned throughout the year. On 15th January – exactly 100 years since Aston Martin was incorporated – the oldest surviving Aston Martin – the A3 – will join the latest Aston Martin Vanquish at Henniker Mews in Chelsea, where Aston Martin originally operated, to unveil a plaque to commemorate the anniversary with the Aston Martin Heritage Trust Walter Hayes Memorial Lecture taking place that evening with Sir John Standing telling the story of Lionel Martin’s early experiences.
