A sub-100g/km diesel Toyota Yaris will be available in 2014 as range structure changes bring the car in line with other Toyota models.

The Yaris adopts a new four-grade structure for 2014: Active, Icon, Icon Plus and Trend. Active and Icon replace the previous T2 and TR designations, while Icon Plus offers a better specification and extra styling elements.

The 2014 Yaris 1.4 D-4D has CO2 emissions of 99g/km, reduced from 104g/km, and is in Band A for Vehicle Excise Duty, with no annual charge. Less money will be spent on filling up as well, as combined cycle economy has improved from 72.4mpg to 74.3mpg.

Active becomes the new entry level model, and has a six-speaker audio system, aux-in and USB connector, steering wheel-mounted audio controls, electric front windows, height-adjustable driver’s seat, seven airbags (including a driver’s knee airbag) and electronic stability control.

Icon adds 15-inch alloy wheels, body-coloured electric heated door mirrors, body coloured door handles, Toyota Touch multimedia system, rear-view camera, rev counter, air conditioning, leather-covered steering wheel and gear knob, and Bluetooth integration.

Icon Plus adds front foglamps, automatic headlamps and rain-sensing wipers, LED rear lights (except 1.0-litre manual), automatic dual-zone climate control, electric rear windows, raised centre console (manual only), cruise control with speed limiter, air conditioned glove box with interior light.

The Trend model adds 16-inch alloys, exterior chrome trim, matt black C-pillar and rear privacy glass and white interior trim inserts.

Hybrid models all come with LED daytime running lights, but otherwise the equipment reflects the rest of the range.

A Smart Pack (£300) offers keyless entry and push-button start, while the Appearance Pack (£750, Icon Plus only) adds a matt black C-pillar decal to create a 'floating roof' effect, plus dark-tinted rear privacy glass and a fixed panoramic roof.

The Protection Pack (£700) provides front and rear parking sensors, floor mats, mud flaps, black side mouldings and boot liner and a rear bumper protection plate.

The Style Pack (£500), includes LED daytime running lights, aluminium scuff plates and chrome trim on the tailgate and exhaust pipe.

In addition, Icon, Icon Plus and Trend versions of the 2014 Yaris can be upgraded with Toyota’s Touch & Go multimedia system (£650), providing satellite navigation, Google Local Search connection and access to a range of useful, downloadable applications.

Prices start at £10,895 on the road for the petrol range, £15,670 for the 1.4 D4-D Icon Plus and £15,495 for the Yaris Hybrid.
