RCA Citroen/Exa Double Challenge project

Second year students at the Royal College of Art in London revealed a series of projects at their interim degree show last week. Developed in collaboration with French automaker Citroen and the Exa Corporation, a leading supplier of aerodynamic software, the Double Challenge project asked students to design an ultra-compact model that could establish a unique Citroën e-vehicle aesthetic for the future, all while adhering to certain aerodynamic criteria that would not only reduce energy consumption and ensure stability at speed, but also visually communicate efficiency through its design. The project, which kicked off in October last year, was closely followed by representatives from Citroen and Exa, who examined each of the projects and chose a winner, Heikki Juvonen, at the event last week.

Audi A5 Sportback

Audi has officially revealed the Sportback, adding yet another model to the A5 range. Blurring the line between a sedan, a coupe and a conventional wagon, the emotional, progressive design measures 4711mm long and 1854mm wide, yet stands only 1391mm high (12mm shorter than a Mercedes CLS). With front and rear ends characterized by horizontal lines, the automaker's characteristic proportions are evident when viewed in profile.

Lexus LF-NX Concept Compact SUV with 2.0 litre turbo petrol at Tokyo

Lexus’ efforts to create an SUV/Crossover to sit below the RX and mop up some of the ever-growing demand for more compact SUVs tried hard to do the whole ‘Ugly but appealing’ school of design the Nissan Juke pulled off, but pretty much failed. There were some good ideas running around, but there were just too many jarring angles on the bodywork and not enough cuteness to love and the interior was very ‘concepty’ with a sea of blue and yellow everything and touchscreen surfaces abounding.
