GQbyCitroen unveiled in London

Two days after unveiling the Survolt and DS High Rider concepts at the Geneva motor show, Citroen last week pulled off a rare surprise by unveiling the GQbyCitroen - its third concept in three days. Instigated around a year ago, the project is a result of GQ Magazine's editor Dylan Jones questioning what his readers' ideal car might look like, and subsequently being put in touch with Citroen's Mark Lloyd, design manager for this project. The concept is a 4.5m long shooting break, based on the C4 platform.

GM have made some moves to consolidate their European operation with a co-operation agreement with Peugeot Citroen, but that deal has more of a sticking plaster feel to it than a real way to fix the issues of over-production in a difficult European market.
