The company claims the it has managed to reduce average consumption by 13.2 per cent across the range (excluding the OPC / VXR model) with 5 out of 6 engines emitting less than 125g/km.
The most fuel efficient model of the range is the new 1.3 CDTI 95HP diesel ecoFLEX model, which achieves 76.3mpg UK (63.5mpg US or 3.7lt /100km) on the combined cycle and 88.3mpg (73.5mpg US or 3.2lt /100km) on the extra urban cycle).
The diesel range also comprises of a 75HP version of the same 1.3 CDTi that emits 114g/km of CO2, and a more powerful 1.7 CDTi which now produces 130HP, yet drops 12g/km in CO2 emissions.
The tweaked 1.0-litre petrol engine gains an additional 5HP for a total of 65HP while CO2 emissions drop to 117g/km. The 1.2-litre petrol also gets a 5HP boost to 85HP while the 1.4-litre petrol now produces 100HP instead of 90HP and returns 51.4mpg (42.8mpg US or 5.4lt /100km), up from the current model's 46.3mpg.
In addition, most models in the range get a new eco gearshift indicator housed within the instrument cluster.
Complementing the powertrain upgrades is a revised chassis with new set-ups for the steering and suspension systems.
The automaker's engineers added softer springs in the front suspension, mated to an anti-roll bar with new bushes and an increased diameter to improve ride and control characteristics. Furthermore, the 2010 Corsa also gets revised damper settings all round, an optional re-tuned ESP system and enhanced steering geometry.
As far as the Vauxhall-badged version of the Corsa is concerned, the new model gains additional standard features such as cruise control and an on-board computer on the SE, SXi and SRi trim levels while the SRi, which starts at a lower price point, gets revised suspension settings, air conditioning, 17-inch five-spoke alloy wheels, and a VXR styling kit fitted as standard.
On-the-road prices for the 2010 Corsa in the UK start from £10,285 for the 1.0-liter 65HP ecoFLEX model and top off at £17,155 for the sporty 1.6-liter Turbo VXR.
Vauxhall celebrates the tenth season of its Fashion Scout with the first ever car-walk. Made out of three new Corsas and hovering 1.5 meters above the ground, the unique installation featured a three hour show as part of London`s Fashion Week. The models, who normally floated on the polished stages in front of Anna Wintour and Co., spent a week tackling the high-rise podium before showing off the carefully choreographed moment.
