Toyota has released the first details about the 2012 Aygo, ahead of its debut at the Brussels Motor Show on January 10th.

Completing the B-Zero platform sharing project triangle between Toyota, Citroën and Peugeot, the Toyota Aygo is the last of the triplets to receive its facelift. Earlier today we reported the other two facelifts for the 2012 Citroën C1 and Peugeot 107. All three triplets make their public debut at the Brussels Motor Show on January 10th.

On the styling front, the model has a Yaris-inspired front fascia with a revised grille and optional LED daytime running lights.  There's also a new hood and restyled steel wheel caps.

The cabin features a revised dashboard, a new steering wheel and colored air vent trim. Other highlights include additional sound-deadening material and a new audio system with Bluetooth/USB connectivity.

Under the hood, the 1.0-liter three-cylinder petrol engine has been upgraded with a new combustion chamber and iridium-tipped spark plugs. Despite the tweaks, the engine still produces 67 hp (50kW / 68 PS) and 93 Nm (69 lb-ft) of torque. However, fuel consumption has been lowered to 4.4 L/100 km (64.2 mpg UK) while CO2 emissions are reduced to 102 g/km.

There will also be a new ECO variant which has longer 3rd gear ratio and low-rolling resistance tires. This will enable the car to average 4.3 L/100 km (65.7 mpg UK) with CO2 emissions of 99 g/km.
