Lower CO2 from new Meriva 05 January 2010 by Parkers Average range CO2 reduction of 15 per cent Rear-hinged passenger doors Low CO2 EcoFLEX version to be offered Vauxhall has unveiled its second-generation Meriva promising lower CO2 emissions across the range and class leading flexibility from its rear-hinged doors passenger doors. The new Meriva, which will be shown in public for the first time in March, is unique in its class with its rear doors hinged at the back, which allows easier access to the rear and makes using child seats more convenient. Vauxhall calls them FlexDoors. The range will feature six turbocharged petrol and diesel engines with power outputs from 75bhp to 140bhp, while Vauxhall promises an average 15 per cent reduction in CO2 for the range - equivalent to 25g/km - along with a 15 per cent improvement in average fuel consumption. Inside there will be a versatile rail system called FlexRail that will allow the centre console area to slide between the front and rear compartments. Vauxhall says the rear seat folding mechanism is now more intuitive and easier to operate, while the position of the seats can still be moved to vary the amount of rear passenger space and boot space. The nre Meriva has a wider stance and longer wheelbase than the previous version, and as well as creating more interior space, Vauxhall also says it improves the car's comfort and driving behaviour. Vauxhall is claiming a unique feature with its back doors that differentiates it from other cars with rear-hinged doors such as the Mazda RX-8 and Rolls-Royce Phantom. The doors can be opened independently of the front doors without the need for the front doors to be open. However, an automatic locking system prevents the rear doors being opened on the move. The Meriva is expected to go on sale in the summer, with prices starting at about £16,000.
