This is America's version of the Toyota iQ, which is being sold as the Scion iQ.
It's mildly modified from the Toyota, getting darkened headlamps and tail lamps, and a new front bumper with modified upper and lower grilles. The changes have prompted some sections of the American media to dub it 'the working class Aston Martin Cygnet".
The second generation Scion's tC coupe was also unveiled. Scheduled to go on sale in the autumn, it gets a new chassis, all-new interior and a more powerful 180bhp 2.5-litre petrol engine with 173lb ft of torque, linked to either a revised six-speed manual gearbox or a new six-speed automatic with sequential-shift.
The panoramic 'moonroof' from the first generation model remains.
