How small (and green) can you go? Manufacturers seem intent on answering this question while promising to deliver top-notch products. Have a look at this offering from Toyota.
The iQ concept, according to Toyota, marks a change in small car design by achieving exceptional space efficiency while meeting the lifestyle demands of modern, urban Europeans.
Falling just short of the three metre mark - the car is shorter than the Aygo, but comparable with Yaris on width and height - iQ has space for three adults and luggage or seating for a child passenger.
A product of Toyota's European design studio, the concept has been "designed to reflect and enhance the lifestyle of its owners" Wahei Hirai, the manager of Toyota's design activities said.
Exterior design has been kept simple with short overhangs and a cab-forward approach.
The cabin is as uncluttered, with the instrument panel and centre console following natural forms.
Space saving is key in a car of this size. The heating unit has been repositioned, a single central dial displays information directly in the driver's line of sight. Audio and navigation controls are steering wheel controlled with the information being projected onto the front screen using head-up display.
Styling inside the cabin is described as being "on the edge", incorporating purple shimmer in the white paint finish, mock snakeskin steering wheel trim and purple accents in the seats, door trim and dashboard.
