The new model will go on sale in the UK on July 1. Both three and five-door versions will be available in three trim grades: T2, T3 and Sport.
From launch Aygo will be powered by a new three-cylinder direct injection 1.0-litre VVT-i engine.
It will develop 67bhp for a top speed of 98mph and 0-62mph acceleration in 14.2 seconds. In 2006 a 1.4-litre common rail diesel engine will join the range.
The target figure for fuel consumption on the combined driving cycle is 61.4mpg, with CO2 emissions expected to be 109g/km (band AA for Vehicle Excise Duty).
A five-speed manual transmission will be standard, but Toyota’s multi-mode manual transmission will also be available as an option, offering a clutchless gear selection.
Electric standard power steering is standard on all versions.
Standard features include colour keyed bumpers, sound system with radio and CD player, folding rear seat and heated rear window with wiper. Driver and passenger front airbags, seatbelt warning system and ABS with Electronic Brakeforce Distribution (EBD) are included in the safety package.
The T3 trim grade introduces colour-keyed door mirrors and door handles, electric front windows, a 50:50 split-folding rear seat, remote central locking, adjustable rear headrests, keyless entry system and an upgraded sound system. Side airbags and ISOFIX child seat anchor points are also provided.
Aygo Sport includes 14-inch five-spoke alloy wheels, integrated front fog lamps and a tachometer. Air conditioning and metallic paint are also options for the T3 and Sport.
Prices will be announced nearer the time of launch.
