Porsche Museum opens 911 Identity exhibition

As the seventh-generation Porsche 911 hits the market, the Porsche Museum is honoring its brand-defining model with a new exhibition called 911 Identity. The display in the company's Stuttgart museum highlights each generation of 911, from the 1963 original through to the 2012 991, offering facts, figures and artifacts from their year of launch. As well as road going variants of the 911, motor sport versions are on show, from the 911 Carrera RS 2.7 Safari, through to the current 911 GT3R Hybrid, via the fearsome 935s of the 1970s and '80s.

SEAT Altea Copa & Altea XL Copa Editions launched. Price from £16,425

The SEAT Altea Copa and Altea XL Copa Editions have been launched by SEAT with more equipment for no more money. The SEAT Altea has been with us for a very long time and is not quite as enticing as it once was as a sporty take on a compact MPV – based on the SEAT Leon with a higher roofline and slightly raised suspension  – so SEAT are launching the Altea Copa (and Altea XL Copa) to try and breathe a bit of life in to Altea sales. In the process of launching the Altea Copa, SEAT are also simplifying the Altea range a bit by dropping the ‘S Emocion trim along with the 1.4 litre 85 PS and 1.4 TSI litre 125 PS petrol engines, which leaves three engines to choose from in the Altea range - 1.2 TSI 105 PS, 1.6 TDI 105 PS, and 2.0 TDI 140 PS.
